very short depressed pale sette, the interstices with thick grey 

 scaling. Elytra short ovate, shoulders sloping, sides distinctly 

 rounded, broadest about middle, apical processes absent. Upper 

 surface convex, with shallow striae containing very indistinct 

 punctures separated by small granules ; these disappear towards 

 apex and are normally hidden by the scaling ; intervals evenly 

 raised and with regular and complete rows of small separated 

 granular tubercles, those on intervals 3 and 5 being often more 

 distant ; tubercles rounded, bai'e and shiny, each with a very short 

 depressed seta, the interstices variegated with large patches of 

 pale scaling, the most conspicuous of which is a lai'ge transverse 

 patch at the summit of the declivity. Legs with pale scaling 

 which is thicker near apex of femora ; the posterior tarsi shoi't 

 and broad, the three basal joints subequal.

Allied to monitor Fahi'., from which it may be distinguished by 

 its different shape, the elytra being shorter and bi-oadei' ; its 

 intervals 2 and 4 are also regularly granulate ; and the central 

 carina on the rostrum is almost obsolete.

Head closely but shallowly punctured and with dense brown 

 scaling, vertex convex, foi'ehead strongly depressed and with a 

 more or less distinct central carina ; anteoculai- furrows deep, 

 approaching very closely above, being separated only by a narrow 

 carina. Rostrum not separated from head by a complete trans- 

 verse incision, as long as prothorax, thick, strongly curved, 

 gradually dilated to apex. Upper surface rugosely punctured 

 and densel}^ squamose, with five narrow cai-infe, the median one 

 sti'aight and distinct, the others undulating and sometimes 

 indistinct, the thi-ee centi'al ones converging at base to form a 

 stout prominent tubercle, which is strongly bifid at apex. Behind 

 the tubercle is a short central carina continuous with that on 

 foi'ehead ; lateral sulci distinct, the upper pair rathei- broader and 

 deeper and uniting at base ; scrobes deep, latei-al and oblique ; 

 inferior basal fuiTow very deep. Antennce short and thick, clothed 

 with faii'ly dense pale setfe ; scape bai-ely i-eaching eye ; the two 

 basal joints of funicle subequal. Prothorax very narrow in 

 comparison with the elytra, as long as broad, apex scarcely 

 narrower than base, sides rounded, broadest well before middle, 

 dorsal anterior margin truncate or slightly convex, ocular lobes 

 prominent. Upper surface convex, moderately closely set with 

 small rounded tubercles, leaving a distinct but narrow central 

 furrow without any carina ; tubercles shiny, each with a depressed 

 seta, the interstices with dense brown scaling. Elytra ovate, a 

 little narrower in S , shoulders roundedly prominent, sides slightly 

 ampliated, broadest about middle, apical processes absent. Upper
