178. Banchus armillatus, sp. n. 



S. A SDiall, l»lack and yellow species, with fulvous femora. 

 JJead not very narrow behind the prominent and internally hardly 

 emarginate eyes, stramineous, with the occiput broadly black above, 

 and the frons and vertex bearing a common quadrate black s])ot ; 

 face nitidulous, very finely punctate and discrete from the apically 

 margined clypeus by a semicircular sulcus ; cheeks subobsolete ; ex- 

 treme apices of the broad mandibles black ; palpi normal. Antenna> 

 black, iiliform and as long as body, with the scape and two basal 

 flagellar joints flaveecent beneath, and the twelfth to twenty-second 

 joints clear white. TJwax black and somewhat shining ; meso- 

 uotum with discal stripes and a hamate mark ou either side in front, 

 prothorax entirely, mesosternum and broad marks on their pleurae, 

 callosities before and beneath all the radices, and the apical half 

 of the metathorax except a dot at its extreme apex, flavous ; 

 metanotum finely trans-aciculate throughout, its s])iracles small, 

 parallel-sided and vei"y sliort, with apophyses obsolete. iScuteVinn 

 glabrous, flavous and simply convex; postscutellum, and the 

 apical lateral carina3 of both, coucolorous. Ahdomen glabrous and 

 strongly nitidulous, apically pubescent, hardly longer than head 

 and thorax, narrower than the latter and apically compressed ; 

 black, with the apical half of all the segments broadly flavous, as 

 is also the subeanaliculate base of the apically unimpressed first 

 segment ; ventral fold strong,, valvulse black and exserted. Legs 

 normal and flavous, with the tibiae distinctly spiuose ; hind coxoe 

 externally, their tx'ocbanters and tibite basally, apices of the latter 

 broadly, and of tlieir fulvous femora narro\\ly, black ; tarsi nigre- 

 scent, the hind ones (except their apical joint) pure white, as are 

 their calcaria which extend to centre of metatarsi. Winr/s clear 

 hyaline, radix and tegular flavous, costa nigrescent, stigma cen- 

 trally ferruginous ; areolet distinctlj' small, transversely trian- 

 gular, subpetiolate, and emitting the recurrent nervure hardly 

 before its apex ; radial cell sublaneeolate, its nervure apically 

 quite straight and basally curved ; first recurrent of hind \^ing 

 opposite, and emitting the nervellus but slightly above its junction 

 with the posterior nervure. 



Length 7 millim. 



NicoBAE. Islands (Col. Bingham). 



Type in the British Museum. 



The small and distinctly triangular areolet, obsolete apophyses, 

 very short spiracles and hardly emarginate eyes are somewhat in- 

 congruous in this genus, to which, however, this species is more 

 closely related than any other yet erected ; and I do not consider 

 these minor distinctions worthy of generic rank. 



Described from ii single specimen.
