new Species of Diploptera. 35 



abdominal segment, base of second segment, the legs (except 

 the coxae), ferrugineous. 



Wings hyaline, somewhat diffused with fuscous on the 

 apical area. Clypeus as broad as long, with a small semi- 

 circular emargination at the apex ; pronotum sharply angular 

 in front ; mesonotum posteriorly with a longitudinal carina, 

 obscure and shining; scutellum prominent, postscutellum 

 with a minute spine on each side, median segment with a 

 distinct longitudinal furrow. 



Abdomen : the first segment as long as thorax, slender, 

 broadening gradually to apex, second segment cup-shaped. 



Punctured ; the clypeus and whole thorax very coarsely 

 and rugosely, first abdominal segment less coarsely, re- 

 maining segments minutely. 



Length 10 mm. 



Hab. Angola (./. J. Monteiro) ; 1 S • 



Has a strong resemblance to R. natalensis, Sm., from 

 Natal, but differs in having no tubercles on the petiole, and 

 in the coarser puncturation of the petiole. It may possibly 

 prove to be the male of R. natalensis, altbough the distance 

 separating the two species geographically is very great. 



Calligaster turneri, sp. n. 



? . Black ; two small round spots on pronotum on each 

 side ferrugineous; tibiae and tarsi of intermediate and poste- 

 rior legs covered with a dense short fulvous pile, the vertex 

 and clypeus Avith a sparse grey pubescence. Clypeus as 

 broad as long, subtriaugular ; pronotum narrow anteriorly, 

 widening to the tegulae ; scutellum flat, median segment 

 rounded posteriorly, with a conspicuous longitudinal depres- 

 sion between the two sides, punctured ; clypeus, mesopleurse, 

 and mesonotum longitudinally striate, a short longitudinal 

 carina between the antennae, vertex rugosely, scutellum and 

 postscutellum coarsely punctured, two longitudinal furrows 

 on mesonotum ; an obscure furrow on scutellum and post- 

 scutellum ; abdomen shining, petiole more finely, following 

 segments minutely punctured, an arched keel on apical end 

 of petiole, a distinct transverse furrow anterior to it. 



Wings pale fuscous, with a metallic-bronze gloss. 



Length 15 mm. 



Hab. Shillong, Assam (i?. E. Turner). 



Easily distinguished from the nearly allied species by the 

 shape of the petiole, which is much shorter and more ovate 

 than in any other species with the exception of Calligaster 

 3-maculatns, Cam., from Darjeeling; in both of these species
