Cidapkurus Jlavomaculatus, Cameron, Zeits. Hym. -Dip. 1904, 

 p.346(d). 



d 1 . A pi'ofusely black-marked red species, with only the mouth 

 and pronotum flavous. Head not strongly constricted behind the 

 internally emarginate eyes, ochreous, with the bordered occiput 

 and ocellar region, frontal marks, cheeks, apices of mandibles 

 and a parallel-sided and entire facial line, black ; face deplanate 

 and distinctly punctate, obsoletely discrete from the smoother 

 clypeus ; mandibles apically subtridentate, with the upper tooth 

 the longer ; palpal joints normal and cylindrical. Antennae not 

 elongate, apically attenuate, black, with the flagellum fulvidous 

 and the scape ochreous beneath. Thorax stout, evenly and dis- 

 tinctly punctate, red, with profuse black markings ; metathorax 

 convex, scabrous, with indistinct punctures and its basal half 

 black ; petiolar costa alone laterally strong, spiracles elongate and 

 apophyses obtuse. Scutellum and postscutellum red and strongly 

 convex, the former with an apical short stout straight black spine. 

 Abdomen strongly compressed throughout, nitidulous, obsoletely 

 punctate and red, with the basal half of all the segments black ; 

 basal segment not impressed, constricted beyond the strongly 

 dentiform spiracles at its basal third ; ventral segments red ; 

 valvulae subexserted. Legs red, with the hind trochanters, an 

 external line on the posterior coxa3 and another beneath all the 

 femora, black ; hind calcaria strongly unequal, front ones and the 

 basal joint of their tarsi sinuate. Wings siliceous throughout ; 

 stigma and nervures piceous, radix and tegulae ochreous ; areolet 

 rhomboidal, distinctly sessile and not large, emitting the recurrent 

 nervure from its centre ; discoidal cell apically acute below ; radius 

 slightly curved above areolet ; nervellus emitted from the very 

 strongly postfurcal first recurrent nervure of lower wings hardly 

 before its junction with the median nervure. 



Length 10 rnillim. 



PUNJAB : Simla, v. 97 (Col. Nurse). 



Type in Col. Nurse's collection. 



The genus Cidaphurus, in which Cameron places this species, 

 was distinguished from the remainder of Sanchus, by Eorster in 

 1868, by its possession of .a scutellar spine, but since every other 

 feature is analogous with Gravenhorst's genus, I do not consider 

 it has any right to a separate existence ; and I am not aware that 

 any systematist has yet made use of it. A great many of Forster's 

 genera are based upon trivial and sometimes merely sexual 

 characters. 



The present species strongly resembles the c? of our common 

 European Banchus pictus ; I have seen only the type.

c? . A black species, profusely marked with flavous and its hind
