of elytra and occupying one-half to three-fifths of costal length; venter 

 and blade of ovipositor yellowish or orange. Wings deep smoky. Head 

 slightly narrower than pronotum; face heavily shagreened; clypeus trape- 

 zoidal, narrowed to a truncate tip, considerably exceeded by the gense; 

 genie deeply creased below the eyes, not angulate outwardly; lone very 

 small, sublinear; front subelliptic, strongly elevated, sides rounding up, 

 but disc flat, even; on upper third with a sharp carina which terminates 

 above in the carinate margin of vertex. Vertex nearly a half longer than 

 width between eyes, a third longer than pronotum, with a delicate longi- 

 tudinal carina; anteriorly subelliptic, apex slightly obtusely angulate, an- 

 terior edge carinately margined ; surface nearly even, longitudinally striate, 

 the striae slightly converging anteriorly, back of the ocelli the striae par- 

 tially replaced by punctures; ocelli large, on the disc of the vertex twice 

 as far from the eyes as from the anterior edge. Prothorax carinate behind 

 eyes, propleurae transversely rugose, the other pleurae also variously 

 sculptured ; pronotum nearly two-thirds broader than long, anteriorly 

 broadly rounded and somewhat narrowed, hind margin gently concave, 

 surface roughly punctured, posteriorly also transversely rugose; scutel 

 shorter than pronotum, variously roughened, with a straight transverse 

 groove. Elytra without an appendix, equaling tip of ovipositor; clavus 

 and basal two-thirds of corium coarsely punctured; last ventral segment 

 of female twice as long as preceding, the hind margin slightly bisinuate. 



Described from two females collected at Rio Janeiro in Sep- 

 tember and October, one female collected at Para in July. 



I take pleasure in dedicating- this species to the veteran South 

 American explorer who discovered it.

By MARTIN L. LINELL. 



(Aid Dept. Insects, U. S. National Museum.) 



TYPHLUSECHUS new gen. 



Body elongate, parallel, margined on the sides, feebly convex, 

 glabrous and nearly smooth. Head horizontal, very large, as 

 long as broad, slightly convex; sides parallel, with obtuse margin, 

 posterior angles acute and prominent, anterior angles obliquely 

 truncate, anterior margin rather deeply emarginate; clypeal suture 

 wanting; labrum concealed ; eyes each apparently of a single 

 ocellus situated in an impressed puncture a little nearer to the 

 lateral than to the posterior margin of the head. Another im- 

 pressed puncture with smooth bottom behind each eye; a short, 

 obtuse, oblique elevation on each side above the base of the an- 

 tennae; mandibles short, bifid at apex; mentum large, transverse
