480 Mr. B. P. Uvarov— ^ Revision of 



1. Pachynotacris amethystina (Bol.). 



**1908. Acridoderes amethystinus, I. Bolivar, Mem. Soc. Ent. Belg. 

 xvi. p. 114. no. 120. 



Bolivar^s type, which I have studied, is badly discoloured. 

 One of two specimens in the British Museum, a female, 

 perfectly identical with Bolivar^s species in all the morpho- 

 logical characters, is very vividly coloured, being black and 

 sulphur-yellow; the elytraare black basally, gradually merging 

 into dark violet towards the apex, with a sharply defined 

 sulphurous stripe in the anal field ; wings vinous, but not 

 amethyst as in the type, which is undoubtedly discoloured ; 

 hind femora black all over except both upper areas and the 

 genicular lobes, which are yellow ; hind tibiae black all over, 

 including the spines. 



Geographical distribution. Stanley Falls (Belgian M. ; 

 Bolivar's type); Entebbe, Uganda, 1 c? , 1 ? (B.M.). 



VII. Genus Bryophyma, nov. 



Frontal ridge in profile distinctly convex, forming a wide 

 curve with the fastigium. Fastigium of the vertex strongly 

 sloping, somewhat convex, its margins not at all or scarcely 

 raised, distant behind. Distance between the eyes distinctly 

 broader than the base of the frontal ridge; the height of an 

 eye in $ distinctly less, in the (^ not more, than the height 

 of the subocular sulcus. Pronotum distinctly compressed 

 laterally, very feebly constricted in the prozona, coarsely 

 punctured and rugulose ; its front margin rounded, slightly 

 prominent in the midd'e ; hind angle about 90° ; median 

 keel in prozona tectiform, deeply cut by transverse sulci, 

 in prozona sharp, lowered before the hind margin. Elytra 

 transparent throughout, with not dense reticulation ; their 

 apex bent backwards, moderately narrow^ed, obliquely trun- 

 cate. Wings faintly coloured. Hind femora distinctly 

 widened basally; supero-external area granulated; the upper 

 keel of the externo-median area denticulate. Hind tibise 

 with 8-9 outer and 10-11 inner spines. Male cerci elongato- 

 triangular, compressed, with the apex incurved. Male 

 subgenital plate short, conical. 



Genotype : Cyrtacanthacris debilis, Karsch. 



Two known species may be included in this genus, namely, 

 dehilis, Karsch, and sigillata^ Bob, and I regard them as but 

 geographical races of the same species. 



1- Bryophyma dehilis (Karsch). (Fig. 3«.) 

 Though the material at my disposal is rather scanty.
