﻿OF THE STATE ENTOMOLOGIST. 55 



SO often bred from ether insects; the other a pretty Ichneumon-fly 

 {Anomalon apicale Cresson) which may be called the Dark-tipped 

 Anomalon. 



Of a lot of over a hundred chrysalides received from Mr. John 

 Davis, Junction City, Kansas, fully forty per cent, were destroyed by 

 this parasite, which undergoes its transformations within the chrysa- 

 lis shell, spinning but a very thin layer of silk on the inside thereof, 

 and issuing finally by gnawing and pushing off the anterior portion. 



It is rather a pretty species, about 0.90 inch long, exclusive of 

 antenna?. The wings are smoky-brown, with deeper brown veins, a 

 golden reflection toward base, and a clearer space at tip of front ones. 

 The face and cheeks are pale yellow, with the top of head and eyes 

 black. The thorax is marked with yellowish-brown and black and the 

 compressed abdomen is reddish-brown, with the truncated end more 

 or less black. The legs are generally pale, with the exception of the 

 thighs and tips of shanks, which are darker. 



The third parasite is a genuine Ichneumon {Ichneumon hrevipen- 

 nis) originally described by Mr. Cresson from Colorado. It may be 

 popularly called the Short-winged Ichneumon and is characterized by 

 its pale reddish brown color and short, smoky wings.* 



KEMEDIES. 



It is quite evident from the foregoing history of this destructive 

 worm that the practical means of counteracting its injuries are 

 chiefly preventive. It cannot be successfully fought in the worm 

 state, and the wheat grower who has been troubled with it should 

 direct his attention to the destruction of the chrysalides by late plow- 

 ing and harrowing and to the capture of the moths in Spring by means 

 of lights and sweetened and poisoned fluids. We can hardly hope 

 that such preventive measures will be very generally adopted, espe- 

 cially as at best they would prove but partially successful ; and I con- 

 fess that the species, from the character of its food and of its life- 

 habits must be, with our present knowledge, placed in the category 

 of insects whose management baffles man, and must be left to the 

 work of their natural enemies. 



DESCRIPTIVE. 



Leucania albilinea — Egg — 0.5 m.m. wide, generally but half as deep, the top 

 and base being quite llattened. Color pale-yellowish, translucent and less iridescent 

 th?L\\ m unipunct a : with rugosities which assume on upward of 30 more or less dis- 

 tinct ribs : becornuig slate colored before hatching: shell extremely delicate and gen- 

 erally collapsing after exit of larva. 



*The specimeu, which Mr Cresson has kindly compared with his type, differs therefrom in hav- 

 ing the wings relatively longer and in tl>e narrow black bands at basal margin of abdominal joints 2, 

 3 and 4, being obsolete. It may be distinguished as a variety of brevipennis for which I propose the 

 variety najne obsolet us.
