front ones lightly produced and acute; with fairly large but 

 not dense punctures; median line absent. Elytra with fairly 

 numerous punctures of moderate size, geminate-striae fairly 

 distinct but irregular; terminated by an extremely short 

 membrane. Hind 'parts with rather dense punctures of 

 moderate size. Front tibiae with apical tooth only, this long 

 and very acute; basal joint of hind tarsi slightly longer than 

 second. Length, 4£ mm.

In Blackburn's table would be associated with discoidalis y 

 which has much longer clothing, bicolorous elytra, etc., but 

 as the basal joint of the hind tarsi, from some directions, 

 appears to be distinctly longer than the second, it might be 

 compared with sericeipenms, from the description of which it 

 differs in many particulars, and notably in its unidentate 

 front tibiae. The black parts are the head, prothorax, 

 soutellum, sterna, base of abdomen, hind coxae, and club. 

 The head of the type (except the clypeus) and hind parts have 

 a curious muddy appearance, that may really be due to dirt, 

 but it certainly does not appear to be in any way abraded. 

 The elytra in some lights have a conspicuous pruinose gloss. 

 The clothing on the under-surface is mostly of a snowy- 

 whiteness, on the legs and upper parts it is more or less 

 stramineous ; on the pronotum the hair is not very long, and 

 is almost evenly distributed (except in front, where there is a 

 rather conspicuous fringe of longer hair) ; on the head (except 

 at base), including the clypeus, it is dense and rather short, 

 on the hind parts it consists of fine evenly distributed (but 

 rather sparse) hair.

o* . Black ; some parts more or less reddish-castaneous. 

 Elytra glabrous, elsewhere with more or less dense, long, 

 erect, white or whitish hair. 



Head with small, crowded punctures, with a few 

 irregularly distributed larger ones ; clypeus highly polished 

 and with sparse punctures, margins rather strongly elevated, 

 sides scarcely diminishing to apex, which is very feebly 

 incurved to middle and with angles gently rounded off. 

 Antennae nine- jointed. Prothorax with sides and base 

 strongly rounded, hind angles widely rounded off, the front 

 ones obtuse, median line very feeble or absent; with rather 

 dense, small, and moderately large, irregularly mixed 

 punctures. Elytra with rather dense punctures of
