102 NEMATUS CAPEE^B. 



3 individuals I have found it very small and almost 

 square. There is no horny point in the second cellule. 

 In the males as a rule the stigma is darker than in the 

 other sex ; occasionally, however, it is quite yellow. 



Larva. The head is of the size of the second seg- 

 ment, the ground colour is yellowish-green or gray, 

 the vertex covered with small brown dots ; the eye 

 spots are black, and there is a small dark stripe 

 above them ; there is a clear light green triangular 

 space on the face ; the mouth is brown. The 

 body is cylindrical, rather thin, narrowed behind ; the 

 skin is beset with dots each of which ends in a hair ; 

 the colour is dark green to the spiracles where there 

 is a narrow white line, below which the colour 

 assumes a lighter tint. The dorsal vessel is observed 

 as a thin black line, bordered on each side by a white 

 one of the same breadth ; these are not visible on the 

 second and last segments. The junctions of the seg- 

 ments are marked by pale thin lines. Over the legs 

 the skin is raised in folds like blisters. The hairs on 

 anal segment do not proceed from raised points as do 

 the others. 



When full-fed the body becomes of a uniform green 

 colour, the white lines having disappeared; the 

 spiracles are then black, the head dark brown. A 

 rather rare variety of the larva is of a crimson-red 

 colour with the usual white lines, this variety being 

 of this red colour before and after becoming full fed. 

 When young the larvas are dull brownish-green with 

 pale yellow heads. 



These larvse feed on various species of Car ex, but 

 they will also eat grasses. Indeed, most of the speci- 

 mens that I have reared were fed on Poa annua or 

 any other grass that could be had conveniently. They 

 are very lively creatures, and roll themselves up and 

 drop at once to the ground if disturbed when feeding. 

 They eat along the edges of the leaves. The oblong, 

 thin brown cocoon is spun in the ground, or in confine- 

 ment between the leaves. The pupa is glassy green
