292 CRAMBUS HORTUELLUS. 



Larva about half an inch in length, and of average 

 build in proportion ; the head has the lobes rounded, 

 and is very highly polished, as is also the horny front 

 of the second segment. The body is rounded above, 

 but flattened ventrally ; it is of tolerably equal width, 

 but tapers very slightly posteriorly ; the skin is glossy, 

 with a semi-translucent appearance, the segmental divi- 

 sions well-defined ; the raised tubercles are polished, 

 large and prominent, and from each of them is emitted 

 a short but moderately stiff hair. 



Ground colour dingy purplish-brown ; head pale 

 yellowish-brown in some specimens, in others very 

 dark sienna-brown ; frontal plate also of different 

 shades of brown in different specimens ; and the 

 tubercles in some are of a darker shade of the ground 

 colour, in others quite black ; spiracles black. There 

 are no other noticeable markings. 



Along with these larvse was one with an olive-green 

 ground colour ; it I kept separate, but as it seemed a 

 slightly more robust-looking creature, and I failed to- 

 rear a moth from it, I cannot be certain that it was a 

 variety of the same species ; C. culmellus and G. pra- 

 tellus occur on the same ground, so it is possible for 

 it to have belonged to either of them. (George T. 

 Porritt, 15th October, 1879; E.M.M., December, 1879, 

 XVI, 162.)

Although this is a very common species, yet its 

 history has, I believe, never been investigated, or any 

 description of the larva published, a desideratum I 

 have herein attempted to supply from the opportunity 

 afforded me by Mr. J. Gardner of Hartlepool, who 

 kindly sent me first a larva, in 1878, and in 1879 a 

 batch of eggs on the 22nd of August; these began to
