intermediate and posterior obsoletely denticulate on the upper side ; 

 tarsi long, basal joint of hind tarsi sub-spinose outwardly. 



The shape of the teeth of the maxillae and also the sub-spinose 

 basal joint of the posterior tarsi certainly closely resemble the 

 genus Anoplochilus, but it differs in many other characters. Its 

 nearest ally is Hcsmatonotus.

albomaculata, Kraatz, Deuts. Ent. Zeits., 1896, p. 370; Kraatz,

Black or fuscous black, shiny but covered on the upper side with 

 an upright sub-flavescent pubescence resulting from all the punctures 

 being setigerous ; under side densely hairy ; clypeus and head very 

 closely punctate, antenna? flavous rufescent ; punctures on the 

 prothorax closely set but with the intervals irregular and rugose ; 

 scutellum roughly punctate on each side ; elytra with the two 

 dorsal costae highly raised and sub-tectiform, in the first interval 

 there is a costa nearly as much raised in the anterior part as the 

 second dorsal one, but which disappears at about two- thirds of 

 the length, in the second interval there is also a costule much less 

 raised, however, than the second dorsal costa, and the deflexed 

 sides, like the dorsal intervals, are somewhat roughly punctate ; 

 on each elytron there are four dorsal white macules — two in the 

 anterior part of the second interval, and two in the posterior of 

 the first — in addition to these there are two marginal ones in the 

 rounded posterior part, and occasionally one on the hind part of 

 the lateral margin ; abdominal segments closely punctate ; pectus 

 closely shagreened. 



Length 11-12 mm.; width 6-7 mm.

 the apical part, which is somewhat deeply incised in the centre, and 

 the outer angles rounded ; palps of the normal shape ; maxillae 

 robust, inner lobe simple, pubescent inwardly, upper lobe with two 

 superposed, sharp, somewhat hooked teeth ; clypeus sub-parallel
