are situated about middle of sides; clypeus not separated from 

 front, produced into a strong marginal carina, surface convex 

 medially, concave laterally, especially over antennal sockets; 

 labrum very short, transverse, feebly chitinized, emarginate in 

 front and with a row of about six stiff hairs; gular region 

 strongly pilose, feebly concave ; mandibles moderately prominent, 

 strongly bidentate apically; antennae stout, shorter than width 

 of front at their point of insertion. Pronotum three-fourths as 

 wide as long, widest at apical angles which are subacute ; narrow- 

 est just before middle and at base; sides feebly sinuate, sub- 

 parallel, front margin straight, hind angles obtuse, hind margin 

 arcuate, surface longitudinally flat, transversely feebly convex, 

 sparsely punctate, the punctures elongate, side margins with fine 

 marginal line. Scutellum transverse, widest behind, finely punc- 

 tate. Elytra slightly wider than pronotum, more than three 

 times as long as wide, base emarginate, humeral angles subacute, 

 sides subparallel to apical fourth, thence conjointly rounded; 

 surface longitudinally somewhat convex, transversely rather 

 strongly convex, strial punctures moderate, the interstices each 

 with a series of slightly smaller punctures supporting fine, 

 decumbent, short hairs. Under surface shining but with irregular 

 microscopic sculpture between the sparsely scattered, nearly 

 obsolete punctures which bear the short, fine decumbent hairs. 



Described from thirty-two examples from a large series 

 collected by Dr. Wm. M. Wheeler at Kartabo in July and August, 

 1920. The sexes are almost indistinguishable unless the "palps" 

 of the ovipositor are extruded. 



Characters of legs, antennae and mouth are shown in accom- 

 panying figures. Type, allotype and paratypes. — Cat. No. 24070,

Although we have seen neither of the two species (Nausi- 

 bius tenebrioyiides and A'^. elongatus Grouv.) upon which Grou- 

 velle, (Ann, Soc. Ent. Fr., vol. 81, 1912, p. 314) established this 

 genus, his generic diagnosis applies so well to the species here 

 described that his genus is adopted. The postcoxal lines are 

 very feeble and difficult to see but are bent abruptly forward 

 to the coxal cavity enclosing a small area under the trochanter:
