In Vol. XXXII. and XXXIII. of the list of Lepidoptera Heterocera in the British Museum, Mr. Walker described some species from “West Canada, in the Rev. Mr. Bethune's collection.” No records of specimens in the Museum are given, and the descriptions are of specimens apparently returned to the collector. On the chance of these specimens being still in existence I wrote Dr. Bethune, begging him for such assistance and information as was in his power to afford. He very kindly responded, saying, “I shall send you by mail to-morrow a box containing the few specimens that I have left that were named for me by the late F. Walker.

Catopsilia neleis, var. floridensis ♂ ♀.

A beautiful variety of C. neleis, Boisd. It differs from its tropical types considerably.

The ♂ ♂ have a bright sulphur-yellow in basal half of primaries, the broad anterior space beingof a creamy white instead of the citron colour in the typical form.

The same is the case with the secondaries, except that three-quarters of the area of wings are of bright sulphur.

♀ ♀ are not yellow, but creamy-white with large black discal spots, black rimmed apices and anterior margins of primaries, and with prominent citron tinge of the basal area of secondaries.

Pyrgus pelagica, n. sp.

Habitat: San José del Cabo, Lower California.

Expanse, 1.25 inches.

Descripition.—Under side of palpi and head covered with whitish hairs; top of same blackish-brown gray; forehead with some whitish hairs mixed with the darker. Thorax and abdoment blackish above, end of abdomen shading into gray, beneath whitish. Legs covered with whitish hairs, brownish at end. Antennæ blackish, with small white annulations at abse of each joint; club above blackish, tipped with light brown, below light brown down to joint.

At different times considerable attention has been paid to the general darkening in colour of our British insects, compared with Centrall European and with American forms. In Britian, many species become much darker(some absolutely black) on various parts of the West Coasts of Ireland and Great Britian, and, as a general rule, the more humid districts produce the darker specimens, e.g. Acronycta (Viminia) euphorbiœ var. myricœ, Xylophasia polyodon vars. infuscata and nigra, Viminia rumicis var. salicis, etc.

Egg.—Diameter, .03 inch; height, .03 inch; blunt conic; smooth. When first deposited white; after a few days yellow. Duration of this period, five days.

Young Larva.—Length, .07 inch. Cylindircal; head a little larger than body; six rows of tubercles bearing long hairs. Colour of body and hairs white; head black; a geminate black spot on top of joint 2. Duration of this period, three days.

Xorides caryœ, n. sp.

Female.—Length 11 to 16 mm. Black with yellowish-white markings. Head swollen, interior orbits, interrupted opposite antennæ punctured, between antennæ and ocelli polished; antennæ slender black. Thorax with the pectus and pleuræ finely punctate, polished; disc of mesothorax transversely rugulose; metathorax rounded, faintly sulcate medially and rugosely punctured and aciculated; sides of prothorax, two lines on mesothorax, two spots, sometimes confluent, on scutellum, the post-scutellum, the tegulæ and a broad stripe of pleura, contined on middle coxa, yellow-whitel legs, including coxæ, pale rufous or honey-yellow, anterior ones paler, the anterior coxæ stripe on middle coxæ outwardly, second joint of trochanters and the knees yellow, tibiæ and tarsi piceous or blackish, the former with a pale line within; wings hyaline, nervures and stigma black.

In September of last year I discovered the larvæ of a species of Nematus feeding upon a willow introduced from Russia by the late Mr. Charles Gibb. Like others of the genus these larvæ were gregarious and threw up the hinder parts of the body when disturbed. They were full fed and buried themselves on September 24th. The flies appeared in the end of March.

In Entom. Amer., Vol. VI., p. 173, in my description of Euchaetes conspicua there is erroneously inserted: “This insect comes near E. cadaverso, Gr.,” etc., etc. This should read: “This insect comes near E. abdominalis, Gr. It is easily recognized by its conspicuous costal lines. E. abdominalis is a Florida insect, whilst this seems to be the Colorado representative.” Entom. Amer. having caeased to appear, you will confer a favour on me by publishing this in your esteemed paper.
