and placed upright against the stems of grass, but resting on the ground at the base, 

 their habit of living and feeding, indeed, being exactly like those of Cramhus 

 Warringtonellus as described by Buckler in the Ent. Mo. Mag. of November, 1880, 

 p. 130. By June 1st they had reached half to five-eighths of an inch, and were still 

 of the pale mahogany tint ; the hind pair of tubercles on each segment had become 

 much narrower than the front pair ; the front pair were nearly round though slightly 

 oblong, whereas the hind pair took almost the form of transverse streaks. At this 

 time most of the larvee appeared to be about moulting, and there was evident indi- 

 cation that with it would be a change of colour, for a greyish tint clearly showed 

 through. By June 17th they were evidently full-grown, and were described as 

 follows : — Length, three-quarters of an inch, stout, and of the usual Cramhus shape, 

 i.e., cylindrical, of nearly uniform width, tapering slightly at the posterior segments ; 

 skin semi-transparent, the head, plates, and raised tubercles, polished ; the front 

 dorsal pair of tubercles on each segment, and those on the sides, round, the hind 

 dorsal pairs narrow and almost oblong ; segments well defined, and each having a 

 sub-dividing transverse wrinkle in the middle. 



The ground is of a greyish-stone colour, some specimens having a brownish tinge ; 

 head usually pale yellowish-brown slightly freckled with darker brown ; but in 

 occasional specimens it is much darker brown ; in all cases the mandibles are dark 

 eienna-brown ; frontal plate of a slightly browner shade than the ground colour. 

 The greenish alimentary canal shows through as the dorsal stripe ; tubercles of a 

 darker shade of the ground colour, each contains a black spot from which springs a 

 single short hair ; spiracles intensely black. Ventral surface of a paler shade than 

 the dorsal area ; anterior legs ringed and tipped, and the posterior legs slightly fringed 

 with dark sienna-brown. 



All through they fed and lived in precisely the same manner ae 

 does the larva of O. Warringtonellus. The first two imagos appeared 

 on July 25th, and the others continued to appear until about the 

 middle of August, by which time T had bred a nice series. Every 

 specimen was of the pale-bronze veined form, and all were, as far as I 

 could judge, exactly intermediate between the ordinary white form of 

 perlellus and Warringtonellus ; so much so, indeed, that I was puzzled 

 to which species they belonged ; and the more so, as on submitting 

 some of them to Mr. Eichardson, he was uncertain as to whether he 

 had ever taken the white form on the ground where he had captured 

 the parent of my specimens. On submitting some of them to Mr. 

 Stainton, however, he referred them to perlellus. 



From the foregoing description it will be found that the larva of 

 perlellus agrees closely with that of Warrinr/tonellus, and the rearing 

 of it has not in any way shaken the opinion I have long held, that the 

 latter is nothing more thnn a form of the former.
