220 Mr. W. L. Distant on Dinidorinae, 



raised, and smoother than in P. quadrloculata. The sculp- 

 ture of the elytra is nearly the same, but the stria? are a little 

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

 with a sandy-white pile, 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 clothed 

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

 coloured) pile; the Hist to fourth segments have each a 

 round smooth spot on each side, and the terminal segment 

 has an oblique smooth line. 



llab. Upper Egypt, Northern Etbai (D. A. MacAUster) ; 

 "White Nile (Consul Pethcrick) ; Nubia; Suez. 



The specimens from Nubia and Suez have the pubescence 

 on the underside of the body sandy coloured. 



XXXI. — Rhynchotal Notes. — VI. Heteroptera: Dinidorina?, 

 Phyllocephalinae, Urolabidinaj, and Acanthosominre. By 

 W. L. Distant. 



This contribution completes the examination of the family 

 Pentatomidse, as contained in the British Museum, including 

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

 o c his 'Catalogue of Hem iptera- Heteroptera ' (1867-8). 

 Some recent acquisitions to the Museum and my own collec- 

 tion are also described. 



Dixidoeinjl. 

 Genus Cyclopelta. 

 Cydopelta dorsaUs. 

 Cyclopelta dorsalis, Walk. 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. 



Long. 10-12 millim.
