DESCRIPTIONS OF TWO NOCTUID LARV2E. 
By Harrison G. Dyar. 
Spargaloma 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 setae moderately long, single, white, normal in arrangement for the Noctuidae, 
iii rather close to the spiracle, iv substigmatal, posterior ; three setae on the leg plate. 
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 ( Apocynuiri ). 
Deva purpurigera Walker. 
Head small, green with black ocelli; width, 1.5 mm. Body slightly enlarged on 
joints 5, 6, 7 and 12; tubercles low rounded cones on the prominent segments, the 
segmental 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 subventrally; 
the subdorsal band is obliquely divided between tubercles i and ii, the hinder portion 
joining 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 
13, reddish tipped; thoracic feet green. Tubercles normal for the Noctuidae, iii, 
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 vii consists of 
three rather distant setae 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.
