It appears that comparatively little is knorvn regarding the external sexual characters of species in the family Scolytidæ. Indeed, the species of this family are among the most difficult of Coleoptera to study, or to properly identify, unless one has access to a large series of correctly named and classified examples.

During the winter of 1891–2, I received from Miss Morton, of Newburgh, N, Y., six cocoons of P. columbia, which she had reared from ova, received from one of her correspondents in Ann Arbor, Mich. They were the first cocoons of that moth I had seen. Their extremely smali size as compared with Cecropia, their natty appearance and dark colour, relieved by flecks of white silk, was quite novel to me, so I frequently showed them to visitors.

The numbering is continued from page 193.

(13.) Tachardia cornuta, n. sp.—♀scales crowded on the stems of the plant, lively red-brown in colour, smooth and rather shiny, subtranslucent; elevated so as to form in outline a triangle, the base of which is greater than either side viewed from one side, but with the sides greater than the base when the scale is viewed from one end.

The following list has for its foundation a collection belonging to the Experiment Station of the Kentucky State College. The diurnal Lepidoptera have not been made the object of special collecting by the Station entomologist, and doubtless a good many species will be added in the future:-

1.Papilio ajax, Linn. Common in all wooded regions throughout the State. High Bridge, Nortonville, Clay's Ferry, etc.

Papilio turnus, ♀, Linn.—I received a curious example of a ♀ P. turnus, which has the outer margin greatly produced towards the apex of the primaries; the secondaries are more rounded and not so elongate as in the typical form; and the black discal bars are broader and more suffused.

The eggs are sub-globular, between that and sub-quadrate, shaped much like Luna and its allies; length, .06 inch; width, .06 inch, by .05 inch in height, smooth the apex flattened, but the base rounded. Colour, olive gree; those on one side of the twig, red tinted. They werr placed round a twig of food plant (willow) with one of the long ways across the twig. They were from California, and where deposited about the last of October. As they hatched the middle of the following April, this would give six months as the duration of this period.

On August 10th, I left by the 4.45 p.m. ferry fro the Isle d'Orleans, whch was reached about 5.30. A short walk uphill brought me to one of my favourite collecting grounds, and the remaining daylight was usefully spent looking for Coleoptera, a few good things being taken.
