 ON THE LARV^ OF TWO NOCTUIDS. 



By L. W. Goodell, Amherst, Mass. 



Charadra PROPINQUILINEA, Grote. — Mature larva, one speci- 

 men ; head round, slightly flattened in front, brown, smooth and 

 glassy. Body thickest near the middle, tapering to each end, of 

 a dirty white, with a large black spiracular spot on all the seg- 

 ments except the last two. It is covered with spreading tufts of 

 short, stiff, white hairs, several of the hairs on the last two seg- 

 ments long and slender, extending over the end of the body. 

 On each of the 4th and nth segments situated close together, 

 one behind the other, are two short pencils of light yellowish 

 red hairs, and on the same segments, just below the hinder pen- 

 cils, is another longer pencil of the same color. All the segments 

 are thickest through the middle. My notes fail to give the 

 length. Feeds on white birch, living in a sort of case made by 

 folding a leaf or drawing two leaves together, and attaching 

 them by their edges with silken threads. It changed to a pupa 

 within its case September 20, and the imago emerged June 6. 



Mamestra assimilis, Morr. Mature larva, one specimen. 

 Head as wide as the first segment of the body ; roundish, reddish 

 horn color. Body smooth, thickest in the middle, tapering 

 slightly to each end ; dorsal space reddish brown, shading to dull 

 red on the subdorsal ; yellowish green beneath. There is a 

 broad, straight, bright yellow dorsal stripe, with a narrow creamy 

 white stripe adjoining it on each side; another narrower bright 

 yellow spiracular stripe, with a creamy stripe adjoining it above 

 and below, the latter edged outwardly with black. Length when 

 at rest 27 mil.; when crawling 33 mil. Feeds on Golden Rod 

 (Solidago). Pupated in the earth September 30, and the moth 

 emerged May 29. 



NEW PYRALID^. 

 By a. R. Grote. 



Cataclysta MEDICINALIS, n. S. 



The smallest species yet known to me, with different 

 ornamentation from the Fiilicalis group. Brown, ochery and 

 white. A broad, inwardly oblique, silvery white sub-basal 

 band continuing over hind wings. A white median patch fol- 

 lowed by a curved white line. A white outwardly oblique band 

 at apical third, nearly meeting a white band along external mar- 

 gin, stopping at the middle of the wing; an ochre shade be- 

 tween the median patch and the oblique costal band; external 

 margin from apices downward margined by an ochre band, nar- 

 rowly divided by a brown line of the color of the wing from the 

 white exterior band ; the brown basal patch includes an ochre
