334 THE CANADIAN ENTOMOLOGIST. 



incompletely areolated, the areola alone complete or distinct pentagonal ; 

 abdomen subfusiform, longly petiolated, about one-half longer than the 

 thorax, subcompressed towards apex and entirely black, except the ventral 

 fold, at apex of the petiole and on segments 2 and 3, which is honey-yellow. 



Type.-- No. 8124, U.S.N.M. 



Host. — Lepidop. Eudemis botrana, Schif. 



Described from two specimens bred by Prof. M. V. Slingerland, at 

 Ithaca, N.Y., from the destructive Grape-berry Moth, Eudemis botrana, 

 Schif. It resembles the European Thymaris pulchricornis, Brischke, but 

 ^differs in sculpture, colour of antennae and legs, and in the incompletely 

 areolated metathorax. 



THE ROSEBUD FEATHER-WING. 

 ( Platyptilia rhododacty/a., Schiff.)

Scarcely a season passes that some newly-introduced, pernicious 

 insects from across the eastern or western oceans are not reported in the 

 United States or Canada. These immigrants, leaving behind them their 

 natural enemies, and apparently greatly invigorated by the change of 

 climate, usually multiply with rapidity and soon prove exceedingly 

 destructive. 



Among others which have recently appeared in the flower gardens in 

 the vicinity of St. Louis is a Pterophorid larva, which bores rosebuds and 

 threatens to become a serious additional pest on the already sorely beset 

 " queen of flowers." 



This insect first attracted my attention two years ago by its 

 characteristic manner of cutting into the receptacle of nearly-opened buds, 

 which caused them to incline on the injured side and form a sort of 

 bracket for the suspension of a rather dense, tent-like web, extending two 

 or more inches down the stem, with which the larva incloses itself as it 

 approaches maturity. 



The mature larva, when extended, measures 10 mm., the broadest 

 diameter being 2.5 mm., thick fusiform. Sutures distinct from their pale 

 colour, though but slightly impressed. General colour pale greenish- 

 yellow, with conspicuous dull red medio-dorsal stripe, most pronounced 

 on thoracic segments, where it is supplemented by two narrower sub- 

 dorsal red streaks. The entire surface has a woolly appearance, with 

 short, coarse, glandular or slightly knobbed hairs, interspersed with longer
