the middle of the abdomen, rounded, and blunt at 

 the anal tip ; the wing-cases nowhere projecting, but 

 smooth and large in proportion, and, like the rest of the 

 surface, unpolished. In colour it is of a dark, dull 

 purplish-brown, and it is thickly clothed with short 

 dark-brown bristles, excepting only the wing-covers, 

 which are blackish- brown and have no bristles. Its 

 appearance would assimilate very well to pellets of 

 earth. (W. B., E.M.M. VI, 38.) 



Cheysophanus Phl^as. 

 Plate XIII, fig. 4 



On the 4th of July, 1876, I received from the Rev. 

 J. Hellins a larva of G. Phlceas, which he had reared 

 to about the length of a quarter of an inch on Bumex 

 acetosa. It continued to feed well on sorrel, and by 

 the 10th of July had attained the dimensions of five- 

 eighths of an inch in length, and was thick in propor- 

 tion, somewhat onisciform, but without any dorsal 

 ridges or hollows ; the back curved, sloping on the 

 sides and at each end where it tapers a little. The 

 second segment is rather longer than the others and 

 bilobed at its front margin, the sides dilated a little 

 below the spiracular region ; the segments very well 

 defined by close and moderately deep divisions ; the 

 belly flat or rather hollow ; the head very small and 

 hidden beneath the projecting lobes of the second 

 segment, as are all the legs beneath the body. 



It is not easy to see the head even when the larva 

 is crawling or feeding, as the bilobed anterior margin 

 of the second segment projects so far over the head ; 

 the notch in the margin of the second segment seems 

 well adapted to receive and steady the edge of a sorrel 

 leaf whilst the larva is feeding. 



In colour the head is pale brown, with a darker 

 brown spot at the base of the papillas, and just above
