P YRA US TID^—NOMOPHILA . 265 



On the wing from June till October, but whether in one 

 or more generations is at present uncertain. 



Larva when at rest only three-fourths of an inch long and 

 tolerably plump; when crawling one inch in length and has 

 an attenuated appearance ; head a little wider than the 

 second, but hardly so wide as the third segment, highly 

 polished, the lobes rounded, and the jaws prominent, varying 

 from reddish-brown to dark sienna-brown, more or less 

 marbled with black, and with the mandibles black ; body 

 attenuated a little toward the extremities, cylindrical, but 

 the segmental divisions being deeply cut, and each segment 

 plump and divided, uneven in appearance ; a polished plate 

 on the second segment is a little browner than the following 

 segments ; skin semi-translucent and glossy, with a tough 

 appearance, warm olive-drab ; dorsal line dark olive-drab, 

 bordered with pale drab and very distinct ; no noticeable 

 subdorsal or spiracular lines, but there is a whitish waved 

 stripe below the spiracles — which are black encircled with 

 grey ; raised dots large, round, black, and polished, each in 

 a circle of pale drab ; ventral surface uniformly semi-trans, 

 lucent, dark olive-green. 



When young and till just before full growth, much more 

 slender, and having the head even larger than the third 

 segment. 



These larvae were about the liveliest creatures I ever 

 reared ; they wriggled backwards and forwards in all atti- 

 tudes, reminding me more of young eels than anything else, 

 in both colour and actions mimicking those creatures most 

 wonderfully. They were, too, very pugnacious, as two 

 coming in contact immediately showed fight, and bit each 

 other with their mandibles most unmercifully. (G. T, 

 Porritt.) 



August and September — doubtless also in other months — 

 on clover, grass, knotgrass, and probably other low-growing 

 plants, Mr. E. P. Felt supplies some interesting details as
