676 . Mr. B. P. Uvarov on new 



rugulose, except in their middle part. Head above smooth, 

 but not shining, and the fastigiura of vertex, therefore, dis- 

 tinctly separated from the ragulose and shining frontal 

 ridge. The median and lateral keels of the fastigiilim well 

 developed. Distance between the eyes subequal to the 

 vertical diameter of an eye. Pronotum very long and with 

 an unusually high and thin, transparent crest; its surface 

 distinctly granulose, except on the lateral lobes, which are 

 coarsely rugulose; transverse sulci feeble, obliterated on the 

 crest; sides of the metazona depressed and forming dis- 

 tinct rounded angles with the lateral lobes ; the length of 

 the lobes not more than half the length of the crest. Pleurae 

 coarsely rugose. Elytra extending well beyond the hind 

 knees ; discoidal false vein straight ; the ulnar furcus with 

 two rows of cells and a straight false vein. Hind femora 

 very narrow and slender; hind tibiae with 14-17 spines on 

 each side. 



Head green, with the lower part of the frontal ridge 

 reddish brown ; middle portion of the cheeks pale ; lateral 

 facial keels and oblique streaks before and behind the pale part 

 of the cheeks blackish ; upper median fascia and postocular 

 fasciae pale buff in the middle, margined with castaneous. 

 Pronotum green, with the typical pattern of the genus in 

 black and buff; the crest reddish buff. Elytra uniformly- 

 reddish brown in the basal half and smoky hyaline else- 

 where. Wings pale yellow basally, hyaline elsewhere, with 

 a narrow fascia, subobliterated in the forepart, not touching 

 the outer margin and not reaching the inner margin. Hind 

 femora with a row of very distinct black dots along the 

 carinas of both outer and inner median areas. Hind tibise

Two males and one female from Entebbe, Uganda (C. C.

A very remarkable species, easily distinguished by the 

 uncommonly high and thin pronotal crest, such as may be 

 seen in the genus Pyrgodera or in some Pamphaginae. The 

 genus Oreacris, Bol. (Ann. Soc. Ent. Belg.lv. 1911, p. 298), 

 is also characterised by a very high crest, but it differs from 

 Gustrimurgus in many important characters.
