squamose, earthy coating ; the clypeus is not shghtly emarginate, 

 nor yet triangular ; the two parts of the divided lateral tubercle 

 of the prothorax are nearly of equal size ; the elytra have equal, 

 regular rows of blunt equi-distant tubercles, and the rows are 

 separated by regular series of broad foveate punctures divided by 

 an intervening granular tubercle uniting on the sides the tubercles 

 of the rows which are there very blunt ; the outer teeth of the 

 anterior tibiae are sharp and strong, the second being divided from 

 the apical one by a very deep emargination, but these teeth are 

 often partly worn out ; the part above the basal tooth is strongly 

 serrate as far as the elbow ; the genital armature is very different 

 from the other allied species ; the forceps are as in T. yonder osus, 

 but bi-sinuate inwardly and with the apical point sharper, longer, and 

 more incurved at tip, the upper lobe is grooved longitudinally in the 

 •centre, the sides ar& produced into two rounded costse sharply declivous 

 behind, and the apical part is elongate, horizontal, very much 

 narrowed and reflexed, and emarginate at tip. 



Length 13-16 mm. ; width 9-ll|- mm.

ACANTHOCEEODES, n. gen. 



Mentum sub-parallel, broadly emarginate at tip, not very convex 

 and bristly, ligula very short, transverse, labial palpi very short, the 

 three joints fitting against one another, apical one as long as the 

 other two together and sub-ovate ; maxillae straight and with the 

 inner lobe quite apical and nearly as long as the maxillae, inner lobe 

 extremely small, slightly penicillate and not hooked ; antennae ten- 

 jointed, first joint thickened but neither dentate nor dentiform, club 

 large, sub-globose, the two joints preceding it fitting close against one 

 another and much broader than the others, eyes very slightly divided 

 by the canthus of the genae and showing as much above as under, 

 clypeus produced triangularly from the genae, carinate and standing 

 high above the labrum and the base of the mandibles, the former is 

 longer than broad and emarginate, the latter are strongly arcuate and 

 dentate at tip only ; prothorax straight in front and with the anterior 

 angles long and straight, convex, nearly parallel laterally but with 

 the basal part arcuate ; scutellum only moderately long, sharply 

 triangular ; elytra globose, striate, epipleiu^a moderately broad but of 

 the same width throughout and with hardly any slope, abdomen 

 contracted and partly hidden by the sub-horizontal epipleura ; inter- 

 mediate and posterior coxae nearly contiguous ; anterior tibiae not
