PLUSIA INTERROGATIONS. 117 



The perfect insect emerged on July 8th, 1869. 

 (W. B., 1869; E M.M., August, 1869, VI, 65.) 



TOXOOAMPA CRACOW. 



Plate CIV, %. 2. 



Larva (when full-grown) one inch and a quarter to 

 one inch and a half in length. When viewed from 

 above it tapers towards the head, and still more 

 towards the posterior end; but when seen sideways 

 appears almost uniformly long and slender. 



Its manner of walking is a partial looping of the 

 first six segments ; the first two ventral pro]egs are 

 very slightly shorter than the others, but to such an 

 extent as to be scarcely noticeable, and it generally 

 assumes an undulating posture in repose along the 

 stem of its food-plant. 



Along the back, commencing on the head, is a dark 

 brown, very finely mottled, broad stripe, widest along 

 the middle segment, and with an additional widening 

 on the eleventh segment ; in the centre of this is a 

 thin, rather paler stripe, enclosing the very dark 

 brown dorsal line. The subdorsal stripes are double, 

 brown, with a paler ochreous-brown ground, followed 

 by a pale stripe of ochreous, enclosing a very thin 

 brown line ; the lateral lines double, dark brown, 

 extending from the mouth to the anal prolegs ; edged 

 above with black at the anterior portion of each 

 segment; the upper one widening below in the 

 middle, along which are some black dots. Belly and 

 legs brown. Within the dark portion of the back, on 

 each segment, are placed four black dots in the usual 

 order, and on the eleventh segment there is an addi- 

 tional black dot on each side, outside the dark region. 

 Subdorsal lines also containing two black dots and a 

 minute ring. 



Went to earth on the 24th of June. (W. B., July, 

 1865 ; E.M.M., August, 1865, II, 67.)
