and elytra pitchy brown with a few small indistinct speckles, 

 part of the veins, a faint fascia before apical angle of corium, 

 its epipleura, and male genital segment dark testaceous ; antennae 

 and rostrum testaceous, first antennal joint and apical half of 

 fourth piceous; legs piceous, tibiae paler in hue, tarsi testaceous. 

 Head as broad as half the basal width of pronotum, much broader 

 than long, densely and finely transversely rugulose, each ocellus 

 placed in a small smooth area narrowly connected with that 

 of the other side along basal margin of head, anteocular part 

 a little longer than the rather small eyes, clypeus somewhat 

 longer than juga, antennae half the length of the body, first 

 joint passing apex of head by more than half its length, second 

 a little longer than first, third a little over half the length of 

 second, fourth subequal to second, rostrum reaching middle coxae, 

 first joint almost reaching base of head. Pronotum with a 

 distinct collar terminated posteriorly by a curved impressed 

 line, not transversely impressed on disk, rather thickly punctate, 

 more finely so on the cicatrical areas, in the center with a short 

 and fine keel not nearly reaching base and apex, lateral margins 

 distinctly though narrowly laminate, almost straight but a little 

 rounded at apex, basal margin slightly rounded. Scutellum 

 plane, rather coarsely and moderately thickly punctate. Corium 

 rather thickly and deeply punctured, median vein straight and 

 simple, but very weak or almost obliterated, arising a little be- 

 hind middle of radial vein. Pectus coarsely and irregularly 

 punctate, posterior border of metapleura punctate, evaporative 

 area a little narrower than the remaining part of the metapleura, 

 extending outward a little beyond apex of orificium, its outer 

 margin a little rounded. Abdomen beneath almost impunctate. 

 Front femora beneath in the basal half with two or three very 

 small and slender spinelets, toward apex with a few setae; first 

 joint of hind tarsi about twice longer than the other put together. 



Length, male, 4 millimeters; width, 1.6.

Lethaeus retusus sp. nov. 



Narrowly elliptical, shining, black or pitchy black, apex of 

 clypeus, pronotal collar and posterior lobe, and male genital 

 segment reddish testaceous, posterior pronotal lobe tinged with 

 piceous in the center, corium and clavus stramineous, their 

 puncturation and a subbasal, median, and apical spot to mesoco- 

 rium piceous, apical half of exocorium together with the adjacent
