Genus SETICORNUTA, gen. nov. 

 GENOTYPE, S. albicalcar, Mori. 



Head narrower than thorax and strongly constricted posteriorly ; 

 frons and vertex obsoletely punctate and shining ; face strongly 

 protuberant, uniformly coarsely punctate and continuous with the 

 hardly smoother clypeus ; mandibles parallel-sided and longi- 

 tudinally striate ; eyes einarginate next the scrobes. Antennae 

 but little longer than half the body ; scape strongly punctate and 

 very little excised ; flagellum peculiarly setiform and basally stout, 

 consisting of some forty-five very strongly transverse joints, of 

 which the apical are carinate beneath. Thorax deplanate, niti- 

 clulous and sparsely pilose ; notauli superficial, though extending 

 to the di.-c ; mesopleurae convex ; metauotum strongly carinate at 

 the apex and equally strongly bicarinate on the disc, rendering the 

 quite circular areola and rather longer basal area conspicuous : 

 costulae wanting; spiracles elongate and occupying the whole space 

 between the two lateral carinae. Scutelluni strongly deplanate, 

 sparsely punctate and bordered only at its base. Abdomen convex ; 

 subparallel-sided and a little longer than the head and thorax, niti- 

 dulous and finely pubescent ; first segment short, and centrally 

 glabrovs beyond the strongly bicarinate base, with basal spiracles ; 

 thyridii wanting ; venter not concave ; terebra hardly visible. 

 Legs, and especially femora, short and stout, the hind tarsi 

 extending to but slightly beyond the anus ; calcaria unequal ; 

 claws small, curved, and not extending beyond the broad pulvilli. 

 Wings ample, but not broad ; areolet entire, small and petiolate, 

 emitting the recurrent nervure from its apex ; basal nervure con- 

 tinuous ; nervellus antefurcal and genie ulate at its lower third. 



Range. Burma and Ceylon. 



Somewhat resembling llyperacmus, but unique in its flageilar 

 conformation. 



223. Seticonmta albicalcar, sp. n. 



$ . A shining black species, with recumbent white hairs, 



rendering the body 

 dull and lending it a 

 kind of bloom. Scape 

 entirely, the ten basal 

 flageilar joints abruptly, 

 the tegulae, the front 

 femora, tibiae and their 

 tarsi, bright fulvous ; 

 hind legs slightly badi- 

 ous ; all the calcaria 

 white ; front wings 

 densely infumate from 

 the basal nervure, and 

 the hind ones slightly
