28 EPUNDA NIGRA. 



half to an inch and three-quarters in length, and were 

 cylindrical, of nearly uniform thickness, with the head 

 rounded, and but little smaller than the second seg- 

 ment, the anal segment tapering at the extremity. 



They were full-fed from the middle of May to the 

 10th of June, and the moths emerged towards the end 

 of October. 



There are several very distinct varieties, and others 

 that may be subdivided into further variations, but it 

 will be sufficient to give details of four, distinct in 

 colour. 



First variety. — Ground-colour a brilliant pale yellow- 

 green, sometimes a very bright grass-green ; others of 

 a bright olive-green, deepest in tint at the extremities, 

 and often suffused with pink anteriorly. 



The dorsal broad stripe in some being faintly 

 blackish, in others reddish, but intensely black or 

 red, forming a dark mark, just at the beginning of 

 each segment; in others this dark spot is confluent 

 with the two anterior tubercular large black dots, 

 thus forming blunt arrow-head marks pointing for- 

 wards. The subdorsal stripe of red or blackish is 

 sometimes complete, but oftener interrupted in the 

 middle of each segment; the skin-folds at the in- 

 cisions are bright yellow. 



The spiracles in all varieties are white, placed in 

 semicircular black marks, and immediately beneath 

 them is a narrow stripe of pale sulphur-yellow or of 

 greenish -yellow; belly and legs pale green, tipped 

 with red at their extremities. The tubercular dots 

 are sometimes absent, but when visible are black, and 

 the anterior pair very much larger than the pair 

 behind them. The head green, suffused with pink; 

 a dull pinkish plate on the second segment. One 

 olive-green larva had the plate dark red, and a large 

 crimson spot on the top of each lobe of the head. 



Second variety. — Ground-colour cinnamon-brown ; 

 a narrow pale greenish-yellow stripe beneath the 

 spiracles ; the folds of skin at the segmental divisions
