504 Mr. H. E. Andrewcs on Oriental Cavabidse. 



of mentum very slender, as long- as side-lobes ; palpi small, 

 last joint hardly dilated, sharply truncate at apex, penultimate 

 of labials bisetose ; labrum narrowed in front, depressed at 

 sides of base, apical pair of setre very small, close together on 

 margin ; antennfe moniliforra, not reaching middle of body, 

 joint 1 = 11 (which is almost pointed at apex), the rest 

 shorter and approximately equal, but 3 is a little longer and 

 2 a little shorter than the others. 



Prothorax hardly wider than head, nearl}^ twice as wide as 

 long, front angles rounded, sides rounded in front, sinuate 

 behind, and falling at right angles on base, hind angles 

 rounded, median part of base very little produced, basal 

 foveae deep, surface fairly closely punctate. 



Elytra rather flat, parallel, half as long again as wide, base 

 depressed but hardly forming a peduncle, punctate-striate, 

 stria 1 arising from an umbilicate pore, intervals a little 

 convex, with two very irregular rows of punctures, 8 wider 

 and irregularly punctate. Underside less closely punctate, 

 and therefore more shiny than in allied species. 



Not unlike Creagris labrosa, Nietn., in form, though quite 

 different in colour, head much narrower and more convex, 

 striae of elytra deeper, surface more finely and more closely 

 punctate, fourth joint of tarsi emarginate only (bilobed in 

 C. labrosa).

Another example, in the British Museum, taken by Doherty 

 in Assam, Patkai Mountains, I put down with some hesitation 

 as a variety of this species. The size is a little larger (7'0 mm. 

 long), the colour of head and prothorax very dark red, and 

 latter a little less contracted behind. The apical joint of tjie 

 maxillary palj)i is rather more dilated. 



Colfax, gen. nov. 



Ligula wide, rounded and thickened in front, depressed at 

 sides beneath, glabrous. Paraglossoi wanting. Meritum with 

 tooth sharper and a little shorter than lobes, latter bisinuate 

 along outer margin, a few setse irregularly placed behind 

 tooth, epilobes hardly perceptible. Mandibles short, wide, 

 w^ith a large rectangular tooth at about middle, between 

 which and apex the edge is emarginate, without sette in scrobe 

 or at base. MaxillcB short, straight, setose on inner side to 

 apex, which is slightly contracted. Labial palpi small, 

 penultimate joint glabrous, last joint elongate-triangular,
