Sept. 1899.] COQUILLETT: LaRV.-E OF SOME LePIDOPTERA. 20i) 



One male, Alexander County, Virginia. Differs from the 9 type 

 in lacking all the dark purple brown shades. The 9 has also four 

 spurs on the hind tibiae but otherwise agrees. 



Larva. — This is the insect figured by Glover, (111. No. Am. 

 Cont., PI. II, Fig. i; PI. 20, Fig. 40) and referred to by me in some 

 detail (Proc. Ent. Soc. Wash., iv, 300). 



The larva occurs sparingly in the vicinity of Washington, D. C, 

 and has been known for a long time to the entomologists of the 

 Department of Agriculture, but has not before been raised to maturity. 

 There are some colored figures of the larva amiong the notes left by 

 Dr. Riley and I have copied a description written by Mr. Pergande. 

 Last season, with the kind assistance of Mr. Schwarz and Mr. Ash- 

 mead, I succeeded in getting a few larvae from which the above 

 described male moth was bred. 



The larva has the arrangement of tubercles of Phobetron and only 

 differs in their special modification. The subdorsal horns are of equal 

 length, the lateral ones though covered by the subdorsals are rather 

 long and slender and the whole larva is of a clear, pale green like 

 glass, covered with the clear, spinulose hairs. Found on beech and 

 oak.

 LEPIDOPTERA.

Hydroecia angelica Smith. 



The larvae live singly in the stems of Psoraka macrostachya, some- 

 times causing the tops of the infested plants to die, but never killing 

 the entire plant. Before pupating the larva gnaws a hole to the bark, 

 but never or very seldom through it, then retires several (sometimes as 

 much as eight) inches below this hole and closes the burrow both above 

 and below itself, pupating within the cavity thus formed. The main 

 burrow usually extends to, but never into the roots. The chrysalis is 

 of the usual form, robust, polished, dark reddish brown and terminates 

 behind in two diverging points; length, 22 mm. Eight of the
