DELPHAX PULCHELLA. 29 



raised, and sparsely furnished with setigerous granules. 

 Abdomen black above. Front legs black, with pale 

 yellow spots. Apex of tibiao whitish. Hind tibiae dark 

 ochreous. The tibial laminated spur is small, but 

 smaller crescentic spurs occur at the bases of the tarsal 

 joints. 



The form of this remarkable insect recalls that of 

 Nepa, the water-scorpion. Its limbs are flattened, like 

 those of the mole-cricket (Grijllotalpa), and are well 

 fitted for burrowing under the roots of grasses in dry 

 places, where it locates itself. It is the sole repre- 

 sentative of the genus in this country, and is rarely 

 taken ; or at least it has been very seldom recorded. My 

 figures are drawn from insects formerly in Mr. Dale's 

 collection. 



Expanse, 7*00 millimetres, or 0*27 inch. Size of body 

 and elytra, 4*00 millimetres, or 0*16 inch. 



Genus IX.— DELPHAX, Fah.

 hind tibiae. A large spur at the base. Abdomen black,

 (post-scutellum). Anal process of the male long, with
