﻿612 Prof. Mario Bezzi's Repoo^t on a Collection of 



Sisyrophanus has more affinity with Bischistus, notwith- 

 standing tlie closed first posterior cell. The South 

 African fauna is rich in species of Bischistus, Avhich have 

 an elongated cylindrical body, and this is to be seen 

 also in the species of Sisyrophanus. 



In the collection are represented two species, which 

 are both different from S. homeyeri and very distinct. 



11. Sisyropha/ivs Icptocerus, sp. no v. 

 (J. Length 11 mm. 



A species near »S^. homajevi, but vvitli black femora, wholly black 

 abdomen and wholly hyaline wings. 



Head black ; face shining black, strongly and conically produced, 

 bare in the middle, with long pale hairs on the sides; eyes touching 

 for a considerable distance ; ocellar tubercle with some black hairs ; 

 on the occiput and- below the hairs are greyish. Antennae black ; 

 the first joint shining, swollen ; the second opaque ; these two 

 joints bear below some strong and long black and white hairs ; 

 third joint opaque, as long as the first two together, much narrower 

 than the first, attenuated at the tip, without distinct terminal style. 

 Proboscis black, 5 mm. long. Upper facets of the eyes distinctly 

 enlarged. Beard dense, white. Hairs of the thorax dense, short, 

 greyish on the upper side, white below ; thorax and scutellum 

 black, without black hairs or bristles. Haltères yellowish ; squamae 

 with white fringe. Abdomen black, clothed with hairs like those 

 on the thorax ; hind margin of the segments with a row of long 

 black hairs. Legs black, the tibiae dark reddish ; bristles of the 

 tibiae black ; hind femora without bristles, with a few white hairs 

 only. Wings pure hyaline, with a small yellowish area towards 

 the extreme base ; veins yellowish ; costal cell dilated at the tip ; 

 anterior branch of third vein very sinuose ; small cross-vein beyond 

 the middle of the discal cell ; anal cell widely open ; first posterior 

 cell very pointed at the end. 



Type $, from Mbwabwa, Momberas, May 1909 {Dr. H. 8. 

 Stannus); a single specimen, not in very good condition. 



12. Sisyrojjhconis pyrrhoccrns, sp. no v. 

 Ç . Length 9 mm. 



A smaller and more cylindrical species, very distinct on account 

 of the bright red third antennal joint and the yellow legs. 



Frons wide, shining black, with a grey band at the base of the 

 antennae and some erect black hairs ; face very prominent, black, 

 very shiny, with a amall yellowish spot at the posterior, lateral
