40 NOLA STRIGULA. 



were constructed, — a circumstance which rendered 

 their detection very difficult. After the escape of the 

 moths, which took place some time about the middle 

 of July, the cocoons still retained their form and 

 appearance. 



For the sake of close examination, one individual 

 was kept without bark until too late for its spinning a 

 perfect cocoon, and at last it attached itself to the 

 underside of a leaf by the tail amongst a few threads, 

 and there pupated much after the manner of an 

 Ejphyra. 



The full-grown larva is but little more than three- 

 eighths of an inch in length ; its body is rather stout 

 in proportion, thickest at the third and fourth seg- 

 ments, and tapered a little from the seventh to the 

 anal extremity ; the head is full and rounded, but of 

 less bulk than the second segment ; the body is 

 rounded on the back and sides, and rather flattened 

 beneath. It has three longitudinal rows of prominent 

 wart-like tubercles on each side, i. e. six on each seg- 

 ment, bearing fascicles of radiating hairs. It has 

 fourteen legs, the first ventral pair situated at the 

 eighth segment. 



The colour of the body is pale buff, sometimes 

 partaking of a flesh tint ; the dorsal stripe is yellowish 

 or whitish flesh colour, very broad, and well-defined 

 by a fine border line of brownish-grey ; the subdorsal 

 line is brownish -grey, but interrupted at the segmental 

 divisions ; all the tubercles are broadly ringed with 

 this colour. A conspicuous blackish-grey blotch covers 

 the back of the seventh segment and extends from 

 one subdorsal line to the other ; there are indications 

 of other blotches of the same colour on the tenth and 

 eleventh segments, but these are cut in twain by the 

 broad, clear, pale dorsal stripe travelling through and 

 separating them into a narrow dark mark on each side 

 of the back. The sides are flesh-colour, the spiracles 

 are entirely hidden from observation by the numerous 

 hairs which diverge near them from the tubercles ;
