DESCRIPTIONS OF TWO NOCTUID LARViE. 

 Bv Harrison G. Dvar. 

 SDargaloma sexpunctata Grote. 



Head small, pale yellowish testaceous, ocelli black ; width, 1.8 mm. Body slen- 

 der cylindrical, green; feet all about alike, the anal pair divergent. Tubercles con- 

 colorous set. moderately long, single, white, normal in arrangement for the Noctuid^, 

 iii rather close to the spiracle, iv substigmatal, posterior ; three set. on thelegplate 

 The larva is without marks, though the tracheal line may be seen with a lens. The 

 last three stages were observed with widths of head .8. 1.15 and 1.8 mm. 



Resembles the larva of Sarrothripa, but the setae are shorter and it 

 spins no web. Solitary on the Dogbane {Apocynwn-). 

 Deva purpurigera Walker. 



Head small, green with black ocelli ; width, i .5 mm. Body slightly enlarged on 

 loints c 6 7 and 12; tubercles low rounded cones on the prominent segments, the 

 egmenlal incisures deep, the segments rounded, so that the larva appears more 

 humped and angled than is actually the case. Color translucent green, not yellowish 

 marked with bright opaque white, in the semblance of oblique transverse bands. On 

 the thorax the white stigmatal band is still intact, though cut down at the incisures ; 

 behind on the abdomen it is cut through at these points and produced subventraly ; 

 the subdorsal band is obUquely divided between tubercles i and 11, the hinder portion 

 ioming the stigmatal white patch centrally on each segment. The bands unite con- 

 fusedly with a narrow geminate dorsal line. Feet only present on joints, 9, 10 and 

 X3 reddish tipped; thoracic feet green. Tubercles normal for the Noctuid^.m, 

 especially on joints 5 and 6, shining black. It was regarded at first as the egg of a 

 parasite till it was noticed that it was alike on both sides. Tubercle vn consists of 

 three rather distant set. on joints 5 to 8. Length about 30 mm. 



Solitary on Meadow-Rue {Thalictrum), towards the end of May. 

 Green and white, curiously hunched up.
