36 MR, G. A, K. MARSHALL OX COLEOPTERA [Jan. 19, 



coarsely punctured, with three prominent narrow smooth carinte ; 

 lateral sulci deep, the upper paii- viniting at base, longer and much 

 broader than the lower pair ; scrobes deep, lateral and oblique, 

 inferior basal furrow absent. Antennce with scape just reaching 

 eye ; the two basal joints of funicle very short, subequal. Prothorax 

 ■comparatively small, somewhat transveise, apex rather narrower 

 than base, sides very little rounded, broadest rather before middle, 

 dorsal anterior margin truncate, ocular lobes feeble. Upper sur- 

 face convex, faiiiy closely set with low i-ounded granules, leaving 

 a shallow central furrow containing a short but sti-ong carina ; 

 granules shiny, beaiing long erect black setas anteriorly, but with 

 short depressed setse behind, the interstices with dense brown 

 scaling. Elytra ovate, shoulders i-oundedly prominent, sides some- 

 what rounded, broadest about middle, apical processes absent 

 in S • Uppei- surface convex, with shallow sulci containing rows 

 of ill- defined punctures often separated by minute granules ; all 

 the intervals with regular rows of closely-set granides, but 1, 3, 5, 

 and 7 are more I'aised than the othei'S, the granules also on them 

 ■iire larger and bear long erect black seta?, whei-eas the granules on 

 the alternate intervals have much shorter subdepi-essed seta? ; the 

 apices of granules bare, the interspaces with dense bi'own scaling. 

 Legs coarsely punctured and with fairly dense depressed pale 

 setae ; posterior tarsi short and broad, the joints of about the 

 same width, 2nd and 3rd subequal in length, 1st rather longer.

Head closely but shallowly punctured and with dense fulvous 

 scaling, vertex convex ; forehead strongly flattened, with a shoit 

 ■deep stria near rostrum, dilating into a broad shallow impression 

 higher up ; anteocular furrows narrow but deep. Rostrimn not 

 incised at base, as long as head and prothorax, slightly curved, 

 dilated only close to apex. Upper surface punctate and with thin 

 scaling, with a shallow central furrow throughout containing a 

 faint carina, and with a prominent carina on either side of it ; 

 upper lateral sulci uniting at base, much longer and deeper than 

 the lower pair ; scrobes lateral, deep in front and shallow behind ; 

 inferioi- transverse basal furi-ow absent. Antennce clothed with 

 pale depressed setje ; scape just reaching eye ; second joint of funicle 

 longer than first. Prothorax distinctly transverse, apex and base 

 of equal width, sides slightly rounded, broadest about middle, 

 dorsal anterior mai'gin concave, ocular lobes well developed. 

 Upper surface convex, the anterior margin distinctly elevated, 

 with a broad smooth central furrow containing no carina, and on 

 each side of it three regular separated i-ows of long spiniform 

 tubercles, there being from 4 to 6 in each row, and those in the 

 lateral row being much shorter than the others ; tubercles bare
