GRYLLID.E. DECTICUS. 17 



having three longitudinal ridges ; the antennas are also shorter ; the 

 elytra are spotted, and in the males are not very much longer than 

 the abdomen, furnished with an ocellus at the base ; the abdomen 

 has in that sex four small styles at the apex, and in the females a 

 longish, more or less recurved ovipositor.

Bright deep apple green ; head with a transverse yellow streak in front ; 

 antennae testaceous^ black without ; thorax entirely green, with three 

 dorsal ridges; elytra not quite twice the length of the abdomen, with a 

 yellow longitudinal streak at the shoulders, vanishing on the disc, the 

 latter with a row of distinct brownish spots and a few smaller dots, the 

 left elytron, in the male, with a rusty ocellar spot, and the right with a large 

 very transparent one; abdomen with a small black dot on the sides of each 

 segment, or in some examples entirely dusky; legs with a brownish spot 

 at the base of the hinder femora ; tibiae somewhat testaceous. 



A very local species : it once occurred in great plenty in a field 

 near Rochester in September, where it was observed by Professor 

 Henslow, to whom I am indebted for fine examples.

 of the same colour, slightly carinated, dilated behind ; abdomen piceous, 

 edges of the segments pale ; elytra pale fuscous, tinged with green, spotted

 the base; wings transparent greenish at their base ; legs griseous-yeilow ; 

 posterior thighs green at their base, variegated with brown. Female dull 

 and pale ochreous, variegated with brown; abdomen pale down the back; 

 piceous on the sides with irregular pale margins to the segments ; ovipositor 

 slightly recurved, brown, with a rosy tinge." — Curtis, I. c. 



Whether this be truly distinct from the preceding I am not prepared to say ; 

 it appears to be so; but, from Charpentier's account, De. verrucivora 

 appears to be a variable insect: — the above description is extracted from 

 Curtis. 



The only examples known of this insect have been taken near 

 Christchurch in the autumn by the late Rev. W. Bingley and 

 Mr. Dale.
