Nothylaeus (Anylaeus) aberrans n. sp. 



$ Black; basal spot on mandibles, spot on basal elevation of labruni, 

 clypeus except upper margin, sides of face evenly narrowed to the eye 

 a little above the antennal sockets, spot on supraclypeal area against the 

 clypeus, obscure stripe on outer side of scape, spot on tubercles, spot on 

 the dorsal one of the two free sclerites of wing base behind tegulae, 

 posterior dot on either side the depression of the scutellum, small spot 

 on base of front and middle tibiae, basal third of hind tibiae, and basi- 

 tarsi outwardly whitish ; rest of tarsi and anterior tibiae and calcaria 

 pale, mandibles except base and flagellum beneath brownish, tegulae 

 piceous, wings hyaline, a little smoky, venation brownish. 



Cheeks and occiput with short, loose, scattered plumose hairs ; collar 

 posteriorly with a feeble band of plumosity ; mesosternum with the sur- 

 face concealed with erect short plumose pubescence, sides and posterior 

 face of propodeum with fine appressed scattered pubescence but little 

 concealing the sculpture; tergite one with interrupted whitish hair band, 

 on posterior margin (abraded), the remaining tergites with very fine 

 scattered whitish hairs, sternites similar, the last two visible sternites also 

 with a few erect black hairs. 



Surface of clypeus uneven, coarsely punctate with ill-defined punctures 

 removed from each other a little more than their own diameter, face 

 and lower part of supraclypeal area with a few similar punctures. Upper 

 part of supraclypeal area, front and vertex very coarsely and confluently 

 punctured, the surface somewhat shining. Supraclypeal area margined 

 with curved carinae above, contracted below, the middle elevated from 

 the contraction, the upper portion nearly in the same plane as the front, 

 with a median low ridge extending to the anterior ocellus. 



Collar margined anteriorly, subinterrupted medially, the lateral angles 

 prominent but blunt. Mesonotum with exceedingly coarse imevenly dis- 

 tributed punctures of different magnitudes, the surface between somewhat 

 shining and irregularly transversely striolate, the parapsidal and median 

 furrows well defined, mesopleura evenly and coarsely punctured, the 

 "punctures separated by about their own diameter. Scutellum deformed, 

 basally with a few punctures and longitudinally lineolate, posteriorly 

 with a profound, rounded, shining excavation a little anterior to 

 two similar postero-lateral excavations and separated from them by 

 two acute edged carinae extending obliquely to the main plane of 

 the scutellum, the posterior excavations are laterally (and partly dor- 

 sally) margined with a translucent almost membranous recurved chiti- 

 nous process. Metanotum profoundly excavated and shining, bounded
