220 Mr. W. L. Distant on Dinidorinas, 



raised, and smoother than in P. quadrioculata. Tho sculp- 

 ture of the elytra is nearly the same, but the stri» are a little 

 more stronjjjlj impressed, and, being filled (in fresh examples) 

 with a sandy-white j)ile, are more conspicuous. The inter- 

 stices are broken up into irregular quadrate spaces by rugose 

 punctures ; the smooth raised parts are more convex than in 

 P. quadrioculata. The underside of the body is clotiied 

 (except along the median line) with whitish (or sandy 

 coloured) [)ile ; the first to fourth segments have each a 

 round smooth spot on each side, and the terminal segment 

 has an oblique smooth line.

'J'iie specimens from Nubia and Suez have the pubescence 

 on the underside of the body sandy coloured. 



XXXI. — Rhynchotal Notes. — VI. Heteroptera : Dinidorinse, 

 Phyllocephalinffi, Urolabidinse, and Acanthosomina^. By 

 W. L. Distant. 



This contribution completes the examination of the family 

 Pentatomidfe, as contained in the British Museum, including 

 the genera and species described by Walker in vols, i.-iii. 

 of his * Catalogue of Hemiptcra-Heteroptera ' (1867-8). 

 SoiBC recent acquisitions to the Museum and my own collec- 

 tion are also described. 



DiNIVOSINM. 



Genus Cyclopelta. 

 Cydopelta dorsalis. 

 Cyclopelta dorsalis, Wnlk. Cat. Ilet. iii. p. 478. n. 5 (1868). 



Allied to C. funebris, Fabr., but not separable by the 

 differential character given by Walker — " somewhat broader 

 than C.funebris^^ — but by having the lateral margins of the 

 pronotum much more oblique and less rounded than in the 

 Fabrician species. 



Cyclopelta parva, sp. n. 



Closely allied to C. obscura, Lep. & Serv., but differing by 

 its much smaller size and by the antenna?, which are shorter 

 and broader than in that species. 



T/ong. 10 12 millim.
