72 CAMPTOGRAMMA BILINEATA. 



and the spiracles is another undulating stripe less 

 pale and faintly outlined with darker; spiracles drab 

 colour, hardly visible. Belly of an ochreous flesh- 

 colour, with a central paler broad stripe and a 

 narrower one on each side, but at some distance. 

 Tiny warty tubercles, each with a fine short bristle. 

 It is rather rugose. Feeds on grass. Tucks its head 

 under the frontal segments on the least alarm. 

 Another larva just like it, but rather yellowish-green.

In the autumn of 1858, in the Entomologist's 

 Weekly Intelligencer, vol. iv, page 188, 1 published my 

 first observations on this species, having then lately 

 reared it from the egg, and proved that the difference 

 between the light and dark forms of the imago was 

 merely sexual. Since then I have reared many more 

 broods from the egg, and have largely supplemented 

 my early record of the various stages, until it seemed 

 that the additional information thus collected might 

 justify another and longer note. 



A more easy species to rear in confinement I do 

 not know ; it seems quite tame and domestic ; only 

 let the temperature be warm enough, the larva feeds 

 quietly and rapidly on food that grows everywhere ; 

 it spins up contentedly; ninety-nine pupae out of 

 every hundred produce perfect imagos, and these last 

 again make no difficulty about pairing and continuing 

 their race. In fact, cold alone, and no mysterious 

 instinct as to certain seasons in the year, puts a limit 

 to the number of broods in any given number of 

 months. Indoors, if the food can be supplied, 

 perhaps six or seven broods might be reared in a 

 year; in 1862 I had a female captured on the 22nd
