5O MEMOIRS ON THE COLEOPTERA 



the thoracic base, simply striate, the first stria bifurcating at base 

 because of union with the scutellar stria, the second with a single 

 setigerous puncture, which is unusually posterior and near the 

 summit of the declivity, the apex obliquely ogival, the sinus broad 

 and extremely feeble; legs moderate, the tibiae and tarsi slender, the 

 basal joint of the posterior tarsi not as long as the next two. 



*Cratognathus 



Body stout, the elytral and thoracic bases not differing much in width; 

 elytra with numerous punctures bearing long setae 6 



6 Anterior tibiae rather slender, of the usual form, not modified ex- 

 ternally or at apex; body nearly as in Cratacanthus in outline. 



Piosoma 



Anterior tibiae with an obtuse prominence on the external edge, the outer 

 apical angle greatly produced in an obtusely pointed and slightly 

 curved process; body larger, broader and still more compact. 



Nothopus 



7 Body oblong, stout, very convex, shining, the elytra deeply striate 

 but without discal punctures of any kind, even the single puncture of 

 Cratognathus and many Harpali being absent, the foveae of the 

 marginal series irregular, the series uninterrupted medially; legs 

 moderate, without special modification Cratacanthus 



8 Body elongate-suboval, convex, the legs rather slender, the anterior 

 tibiae unmodified sexually, slender, with a small slender terminal 

 spur; elytra with serial punctures on the alternate intervals toward 

 apex only Glanodes 



The above outline of Cratognathus Dej., is drawn from a pair 

 that I took at Wellington, near Cape Town, South Africa; the species 

 is probably capensis Cast. As stated by Lacordaire, Dejean was 

 mistaken in assuming that his type species was from South America. 



Geopinus Lee. 



The body is large in size, very stout and convex and of a peculiar 

 pale tawny yellow color throughout, with the exception of some 

 indefinite shading occasionally on the pronotum and elytra. The 

 mentum is devoid of any trace of tooth, as in all the genera of 

 the tribe excepting Cratacanthus, the head large, with relatively 

 rather small but prominent eyes, the palpi moderately slender, the 

 second of the labial with numerous bristling setae, the last joint 

 of both with but few short erect setae, the ligula long, gradually 

 feebly dilated apically, free and with two very long setae at the 

 truncate apex, the paraglossae flat, truncate, not very wide and 

 shorter than the ligula. The antennae are relatively very short and 

 rather thick, though filiform and the labrum is shallowly but acutely
