Coleopt:, p. 702. 



Suboblong, slightly convex, without evident inequalities, subopaque ; 

 piceous. k'gs aJid scape dull fusc:i-i ut'ous, funiculus and tarsi shining, 

 the former rufous, the latter chestnut-red; densely covered with small 

 but not rotundate brassy or lig!it-c(qipery S(]uamae of a sliglitly metallic 

 lustie, (in the scutellum and along the middle of the thorax especially; 

 the setae, though numerous, are not very conspicuous, they are infuscate 

 grey and somewhat irregularly concenti'ated o]i the after part of the 

 elytra. 



Nostrum rather shoi'ter than the thorax, lialf its width, with a sliglit 

 carina extending from the bare apex as far as the eyes. Head short, not 

 marked oft from the rostrum. Eyes subrotundate, free from the thorax, 

 i-atlier small but prominent. Thorax sliglitly broader than it is long, 

 rather broader near the front than elsewhere, base and apex truncate; 

 disc just a little uneven, having a shallow inipression near each anterioi- 

 angle and a slight ridge along the middle; there is no visible jiunctation, 

 but a few minute blackish granules can be seen. Scutellum short, covered 

 witli brassy scales. Elytra twice as long as the thorax, a little broader 

 than it is at the base, where they are narrower tlian in the middle, 

 nidderately conti'acted Init nut (piite vertical beliind ; tliey are inde- 

 finitely seriate-punctate, and bear many minute granules; the 3rd 

 inteistices are slightly and obtusely elevated at the base, and somewhat 

 nodiform on top of the posterior declivity, where the 5th ai-e also sliglitly 

 raised; tlieir surface is slightly uneven, l)ut tliere is no post-liunicial 

 dilatation. 



Scape stout, gradiially incrassate, wdth slender setae; it attains the 

 back of the eye. Funiculus with fine greyish setae, basal tw^o joints 

 moderately elongate and about equal; joints 3-7 moniliform, not longer 

 than broad, and scarcely differing from one another. Club oblong-oval, 

 triarticulate, densely pubescent and dull. 



Legs stout, thickly squamose and setose; tibiae flexuous and 

 muci'onate, posterior corbels without any external truncature. 



Ocular lobes absent. Scrobes deep, quite open above, beginning at 

 the apex and separated from the lower and front part of the eyes by 

 squamose intervals. 



Length (rostrum inclusive), 6 mm. ; breadth, nearly 2J mm.

 sent to me by Mr. F. Flynn in March, 1911. 



Tliis differs from //. ncuhifux, 2868, in having a shorter, l)roader, and 

 less uneven tliorax; the scutellum is covered with brassy s-cales ; the eltyra 

 have no dilatations beliind tlie shoulder; and the antennal club is mani- 

 festly broader.
