Terporopus, n. g. 



Head partially concealed, forehead lightly sinuous. Eyes 

 rather large, ovate, rather coarsely faceted. Rostrum rather 

 long and thin, moderately curved, with a shallow groove 

 on each side above scrobe. Antennae thin ; scape inserted at 

 about middle of rostrum, shorter than funicle ; all the joints 

 of the latter elongate ; club ovate, twice the width of funicle. 

 Prothorax subquadrate, constriction slight; ocular lobes 

 obtuse. Scutellum absent. Elytra rather long and deep, 

 almost parallel-sided. Pectoral canal deep and narrow, ter- 

 minated immediately behind anterior coxae. Mesosternal 

 receptacle raised, longer than wide ; sides incurved to base, 

 emargination widely transverse ; cavernous. M etasternum 

 about half the length of the following segment ; episterna 

 narrow and depressed. Abdomen rather small, narrow, and 

 nowhere suddenly lessened, sutures deep, straight, and dis- 

 tinct ; first segment moderately large, as long as the three 

 following combined, intercoxal process narrow ; second very 

 little longer than third ; third and fourth combined slightly 

 longer than fifth. Legs long and thin; posterior coxae 

 touching elytra ; femora not grooved, acutely dentate, pos- 

 terior passing elytra ; tibiae thin and lightly compressed, 

 diminishing from base to apex ; tarsi long, thin, shining, and 

 very sparsely clothed above, third joint not much wider than 

 second, deeply bilobed, but not to base, fourth long and thin. 

 Elongate-elliptic, strongly convex, squamose, tuberculate, 

 apterous. 



The nearest ally of this genus appears to be Stenoporop- 

 terus, from which it can be readily distinguished by the legs, 

 antennae, and frontal excavations. 



Terporopus tenuicornis, n. sp. 



Black, antennae pale-red, the tarsi darker. Moderately - 

 densely clothed with muddy-brown scales, interspersed with 

 longer and suberect scales, that on the prothorax and elytra 

 form feeble fascicles. 



Head feebly convex; basal half rather coarsely punctate, 

 subopaque, and scaleless ; forehead lightly quadrisinuate ; an- 

 terior half with moderately-dense concealed punctures ; a very 

 feeble elevation on each side of middle. Rostrum slightly 

 longer than prothorax, sides feebly incurved to middle ; basal 

 third with strong punctures in feeble rows, separated by feeble 

 ridges, elsewhere polished with moderately small and rather 

 dense punctures. Scape the length of five following joints; 

 first joint of funicle slightly shorter than second and slightly 

 longer than third, third slightly longer than fourth, the others
