Head large, rather sti'ongly convex, densely, strongly and 

 equally punctate throughout. Rostrum slightly shining, basal 

 two-thirds subparallel, apex enlarged, not very densely or coarsely 

 punctate, an almost impunctate median space. Scape the length 

 of four basal joints of funicle, in 9 inserted almost in exact 

 middle of and just extending to apex of rostrum, in ^ inserted 

 slightly nearer to and just passing apex. Prothorax feebly (by 

 measurement) transverse, but apparently as long as wide, apex 

 depressed and subtubular, with dense large round I'egular punc- 

 tures smaller at apex than elsewhere. Elytra subcordate, slightly 

 wider than prothorax at base, widest slightly before middle; 

 punctures large, oblong ; interstices narrower than punctures, 

 especially those in the 5th-7th .strife, irregularly and feebly 

 wrinkled and obsoletely punctate. Aletasternum with a depression 

 on each side. Basal segment of abdomen rather feebly and irregu- 

 larly punctate, intercoxal process with a feeble sulcus on each side, 

 2nd segment rather more strongly punctured than 1st, its length 

 in the middle equal to that of 5th; intermediates each with two 

 very irregular rows of squamose punctures. Anterior femora 

 with a very feeble tooth visible from but few directions. 

 Length 4, rostrum 1; width 2 J mm.

Although by actual measurement this species is seen to be not 

 twice as long as wide, it appears to be much longer. Of the two 

 other species [foraniinosus and eubterraneus) having the head 

 strongly and equally punctate, the present may be distinguished 

 by its more elongate shape, but especially by its much less coarsely 

 punctured prothorax and femoral tooth (if such it can be called, 

 as it appears to be a feeble triangular extension of the ridge 

 bordering the median groove). Mr. Masters has lent me two 

 specimens labelled Tenteyia Itypocrita, Pasc. MS. ; the species, 

 however, is a true Decilaus ; Tentegia is described as having 

 linear tarsi.
