THE ENTOMOLOGIST. 325 



S. subquaclratus, female, is at ouce distinguished by the 

 quadrate form of tJie head from the same sex of all the other 

 species ; the male most closely resembles that of S. gibbus, 

 the antennae being equally elongate and the joints monili- 

 forra, but the head is proportionably narrower and sub- 

 qnadrate, and the thorax is much more closely punctured. 



S. ephippia is distinguished by its small size; its head is 

 subquadrate, which separates it from small examples of 

 S. rufescens : some other distinguishing characters will be 

 found in the remarks upon that species. 



S. fuscipennis is at once known by its large size and black 

 wings.

Description of the Larva of Emmelesia decolorata. — In 

 last month's number of the ' Entomologist' (Entom. iii. 318), 

 Mr. J^orritt has given a graphic and most interesting account 

 of the proceedings of the female imago of this Eunnelesia. 

 As soon as the young larva emerges from the egg it per- 

 forates the capsule of the food-plant, Lychnis dioica, and 

 feeds on the seeds contained in the interior, of which it 

 henceforth takes possession, and uses, both as a granary and 

 dormitory, never leaving it unless for a similar tenement : 

 within this dwelling it rests in a bent posture, thus accom- 

 modating its body to the requirements of the chamber : 

 when extracted it crawls rather rapidly until it finds a 

 vacated capsule or some similar recess, where it can remain 

 concealed from observation : it is full-fed towards the end of 

 July. The head is narrower than the 2nd segment, ]jorrected 

 in crawling, very glabrous, and not notched on the crown ; 

 the body is rather obese, almost uniformly cylindrical, and 

 entirely without humps, but it has a few minute warts, each 

 oiwhich emits a fine but short hair from the sunnnit; the 

 2ud segment has a double dorsal glabrous plate. The colour 

 of the head and dorsal plate is wainscot-brown : the body is 

 putty-coloured, with two rather distant, rather narrow, purple- 

 brown stripes ; below each of these, yet above the sjjiracles, 

 is a linear series of markings of the same hue ; and below the 

 spiracles is a narrow stripe, also oi the same i)inpie-brown
