DlABATHRARIUS SETULOSUS, sp. iiov. (Plate LXYI. fig. 10.) 



Long. 5|-6, lat. 2-2| mm. 



Head strongly deflected, retracted and invisible from above when 

 at rest ; forehead convex, covered with dense brown or grey scaling 

 and without any central sti'ia ; eyes broadly ovate, not acuminate 

 inferiorly. Rostrum shorter than head, somewhat ampliated at 

 apex, its upper surface almost plane, squamose uniformly with the 

 head at base, bai-e and rugosely punctured at apex ; antennae 

 fei'ruginous. Prothorax longer than broad, its sides scarcely 

 rounded, broadest at base aiid gradually narrowed from there to 

 apex, base deejDly bisinuate, apex strongly and roundly produced 

 above head, ocular lobes obsolete, gular sinuation very deep ; 

 upper surface convex, closely set with laige subi'eticulate punctures 

 and with a distinct comjolete central furrow ; the sculpturing is, 

 however, very largely concealed by a thick brown or grey indu- 

 mentum ; the larger punctures bear short thick erect seta?, which 

 are more numeroxis and paler along the apical margin. Elytra 

 jointly trisinuate at base, somewhat broader than the prothorax 

 at the shoulders, which are sloping, sides subparallel to beyond 

 middle ; scutellum distinct, densely squamose but not prominent ; 

 upper surface convex, with rows of large separated foveolse which 

 are partly concealed by a. thick greyish indumentum ; the intervals 

 narrow, plane, coriaceous, and with rows of short thick distant 

 erect setfe, which ai-e more numerous posterioi'ly and a number of 

 which unite to form a prominent fascicle on the declivity of the 

 third interval. Legs covered with thick grey or brown indu- 

 mentum ; tibise with two short stout teeth internally at apex ; 

 tarsi short and broad, fourth joint entirely absent.
