124 MR. CLAUDE MORLEY ON AFRICAN 



Length, 23 mm. $ only. — Very like Catadelphus nigrocyaneus 

 Tosq., though with the head not quadrate and entirely red, the 

 anus white, &c. — The type occurred to Delme-RadclifFe at Msozi 

 in Uganda during February 1903. 



Erythrojoppa. 



Cameron, Ann. JSTat. Hist. ix. 1902, p. 146. 



Head with the labrum exserted, and clypeus apically truncate ; 

 base of flagellum usually broadly rufescent, its centre in 5 some- 

 what strongly dilated. Base of metanotum deeply discreted and 

 vertically elevated ; areola small and tuberculiform, not laterally 

 carinate nor depressed ; arese entire ; petiolar area basally 

 carinate, narrow and a little explanate throughout ; apophyses 

 wanting. Scutellum pyramidal and in S discally acute ; higher 

 than mesonotum and laterally carinate at least basally, with 

 its basal declivity in S subvertical and the apical oblique. 

 Abdomen elongate and usually narrow, about double length of 

 thorax ; postpetiole distinct ; discal stride of second segment 

 centrally elevated ; venter with segments two to four plicate and 

 the apical obtuse, nearly as long as penultimate. Legs elongate, 

 with tarsi spinulose ; hind femora not extending to apex of third 

 segment. Areolet broadly triangular, coalescent above ; nervelet 

 often distinct ; recurrent nervure centrally, and radius basally, 

 sinuate ; basal nervure subcontinuous through median, — The 

 great majority of Peter Cameron's genera are unintelligible 

 without reference to the types ; those of Erythrojoppa are in the 

 British Museum, and his four Indian species seem to represent 

 the opposite sexes of but two. The following insects are suffi- 

 ciently homogeneous, though the abdomen is a good deal broader 

 and more deplanate than in those formerly described. 



1. RUFIPEDALIS, Sp. n. 



Dull pale ferruginous, with the abdomen blue and wings 

 evenly nigrescent ; base of propleurss black-marked. Head pos- 

 tei-iorly baccate and nearly as broad as the often testaceous eyes ; 

 ocellar region circumsulcate ; frons concave and I'adiately striate 

 from scrobes ; face closely and confluently punctate, centrally and 

 laterally elevated ; clypeus large, distinctly and evenly punc- 

 tate, laterally elevated, with its apex truncate and stoutly mar- 

 gined. Antenna; subdilated beyond centre and apically attenuate ; 

 fourteen basal flagellar joints bright testaceous and remainder 

 black. Thorax robust and stoutly sha greened ; notauli short and 

 distinct, sternauli wanting ; speculum glabrous and impressed, 

 finely striate below ; metathorax evenly coriaceous with complete 

 arese and strong carinse ; petiolar area very narrow, trans-striate 

 and extending nearly to base ; spiracles linear, apophyses want- 

 ing. Scutellum strongly convex and almost pyramidal, discally 

 obtuse, shining and pilose with a few sparse and fine punctures.
