702 ME. R. E. TURNER ON 



rugose, almost vertically truncate posteriorly. Abdomen much 

 longer than the head and thorax combined, not very slender, 

 sparsely punctured, the segments rather strongly constricted at 

 the base, subsessile, the first segment no longer than the second. 

 Sixth dorsal segment more coarsely punctured, not convex, the 

 lateral margins raised, the apical emargination shallow, much 

 broader at the apex than deep. Radial cell broad, nearly twice 

 as long on the costa as the greatest breadth ; second abscissa of the 

 radius distinctly longer than the thii'd, second recurrent nervure 

 received close to the middle of the third cubital cell.

 Jiraxms). 



This species is easily distinguished by the absence of any 

 emargination of the eyes, the shallow emargination of the apical 

 dorsal segment, the strongly constricted abdominal segments, and 

 the broad radial cell. The cubital and discoidal nervures are 

 continued very little beyond the cells, and the two nervures 

 emitted from the apex of the median cell of the hind wing are 

 very short.

 dorsalihua 2-3 macida laterali totrinque alba; alls fusco-violaceis. 



Long. 10 mm. 



$ . Shining and almost smooth, coarsely but not very closely 

 punctured round the base of the antennae ; a few scattered 

 punctures on the vertex, pronotum, mesonotum, and scutellum, 

 pro- and mesopleui'8e strongly but not very closely punctured ; 

 median segment closely and rather finely punctured at the base, 

 almost smooth in the middle and at the apex, a few obscure striae 

 at the posterior angles ; abdomen almost smooth, with a few 

 small punctures on the apical portion of the segments. Long 

 black pubescence on the sides of the thorax ; calcaria whitish. 

 Eyes rather narrowly ovate, cheeks as broad as the eyes ; ocelli 

 small, the posterior pair about as far from each other as from the 

 eyes; Antennae smooth and shining, the scape beneath punctured 

 and clothed with long hairs. Head subrectangular, half as broad 

 again as long, much broader than the thorax. Pronotum about 

 twice as broad as long, the posterior margin almost straight. 

 Mesonotum only half as long as the pronotum and a little shorter 

 than the scutellum, the parapsidal furrows very distinct. Apical 

 segment of the abdomen convex, long, and pointed. Wings of 

 moderate length, reaching to the fifth abdominal segment, the 

 stigma situated about halfway between the base and apex ; 

 iieuration similar to that of rufifrons Fabr. 



IIah> Fourteen Streams, Cape Colony ; January (Dr. Brauns). 



There is only a very obscure median sulcus on the median 

 segment; The slit in the fore wing extends from the termination 

 of the cubitus just beyond the third cubital cell to the margin of 

 the wingi
