A Classification of Lepidopterous Larvae. 211 



lateral rows of little, shallow, pale colored pits. Color dark pur- 

 plish vinous; a pale yellow, elliptical spot dorsally on joints 5 and 

 11 edged with blackish; a much larger similarly colored one on 12 

 on each side behind the large process ; a large bright green patch 

 covers the back and sides of 6 to 10 like a blanket, extending a little 

 on 11 and 12 laterally, and leaving an elliptical patch of the ground 

 dorsally on 1 to 9 like a hole in the blanket. The blanket patch is 

 narrowly edged with black and broadly with white. Spiracles 

 round, elevated centrally, finely radiate, yellowish. Yenter whit- 

 ish, nearly colorless. Thoracic feet small, tipped with brown. 

 Head nearly colorless, black at the sides, mouth brown. 



Sibine trimacula Sepp. 



In this curious larva the long horns have disappeared, and we 

 find on the corresponding segments rounded, spinous tubercles. 

 The lateral series does not appear in Sepp's figure, and nmst be 

 greatly reduced, perhaps to merely a fringe of spines. The light 

 green blanket covers the whole of the dorsum and extends forward 

 laterally to joint 4. being without a "hole" centrally, and bordered 

 with yellow. The rest of the body is bright green, the small tuber- 

 cles only retaining the purplish color. The larva is much less con- 

 spicuous than the others of its genus, in correspondence with the 

 marked reduction of its defensive armor. I am unable to under- 

 stand why Mr. W. F. Kirby should have placed the names of this 

 species and S. vidua as synonyms of the same insect [S. nesea), as 

 he has done in his catalocrue. 



Parasa chloris Henich-Schaflfer. 



This larva is in a state of transition toward the second group. 

 The tubercles are much reduced, and the color, though ratlter bright, 

 is quite uniform, so that it is difficult to decide whether it is intended 

 for warning or not. 



Outline from above somewhat ovate, the last segment produced 

 into a little pointed tail; dorsal region flat, highest at joint 5, 

 diminishing to the extremities. Subdorsal ridge angulated, not 

 elevated, bearing on each segment after 2 a large round wart 

 covered with spines, those on 3, 4, 5, 11, and 12 large, the rest 

 much smaller. A similar row above the spiracles, all small. The 

 head is retracted within joint 2, and this in turn under joint 3. 

 There is a double row of blackish impressed spots in the dorsal 

 region, and elliptical depressions on the sides ; but the skin is nearly
