deeply incised at base, gently curved, the sides parallel to beyond 

 middle and sliglitl)^ dilated at apex ; upper surface convex, with 

 five narrow undulating carinfe, the centi'al one sometimes a little 

 higher than the others ; the two lateral sulci on each side narrow, 

 deep, and of equal length ; scrobes deep and latei-a'l ; inferior 

 basal furi-ow veiy deep. Antennce with the scape reaching eye, 

 the first joint of funicle longer than the second. Prothorax 

 as long as broad, sides subparallel from base to beyond middle, 

 thence rapidly narrowed to apex, anterior margin truncate dorsally ; 

 ocular lobes well developed ; upper surface slightly convex, densely 

 and evenly set with lai'ge rounded gi-anules and without any trace 

 of a central furrow, entirely devoid of scaling. Elytra oblongo- 

 ovate, much narrower in S , truncate at base, shoulders prominent 

 and subrectangular, sides slightly romaded, broadest about middle ; 

 apical processes absent in J , very small in 5 . Upper surface 

 convex, without any distinct sulci, the whole surface being densely 

 covered with even and regular rows of large i-ounded granules ; 

 these granules bare, and each with a short depressed dark seta ; 

 the interstices entirely devoid of scales, except for a few along the 

 extreme lateral margin. Legs rugose, with black setae on the 

 tibife and a few v/hite ones on the femora ; the inner edges of tibiae 

 strongly dentate ; posterior tarsi with the three basal joints sub- 

 equal in length and breadth.

Very nearly allied to corpidentus Gyl., which, however, has the 

 rosti'um shorter, thicker, and more strongly curved ; the prothoi^ax 

 is also much larger in proportion to the elytra in corpidentus, the 

 elytra are less elongate and jointly sinuate at the base with the 

 humeral angles projecting forwards, whereas in monUis the base 

 is truncate with the shoulders subrectangular.

Long, lli-llf, lat. 44-5f mm. 



Head convex, with scattered fine punctuation ; forehead with a. 

 deep central impression ; anteocular furrows deep. liostruin sepa- 

 rated from head by a deep incision, as long as prothorax, strongly 

 curved and moderately dilated at apex ; upper surface almost 

 plane, rugosely punctured in the central portion and with a broad 

 smooth centi-al carina ; the lateiul sulci broad and deep, the upper 

 pair only uniting at base, the lower pair much shorter ; scrobes 

 deeji and latei-al ; inferior basal furrow very broad and deep. 

 Prothorax broader than long, apex scarcely narrower than base, 

 sides strongly rounded, broadest at middle ; apical margin 

 faintly concave dorsally ; ocular lobes moderate. Upper sur- 

 face slightly convex, evenly set with small rounded tubercles, 

 leaving a narrow central furrow containing no carina ; tubercles 

 bare, the interstices with a few scattered pale scales. Elytra 

 oblongo-ovate, truncate at base, shoulders prominent and sub-
