Head strongly convex on vertex, transversely flattened, behind eyes, 

 deeply inserted in prothorax, not visible from above, with or without 

 a short, transverse elevation at middle behind clypeus ; clypeus slightly 

 convex, broadly truncate or vaguely, shallowly emarginate in front, 

 anterior angles obtuse or rectangular ; clypeal suture distinct at mid- 

 dle, obsolete at sides; labrum short, strongly transverse, subtruncate 

 and densely ciliate with long, yellow hairs in front; margins of 

 buccal cavities not dentate below eyes ; mandibles more or less attenu- 

 ate toward apices; eyes oval, globose, strongly projecting. Antenna 

 10-segmented ; first and second segments robust, first elongate, second 

 oval, shorter than first ; third to seventh segments short, oval, trans- 

 verse, narrower than second segment, subequal in length to one an- 

 other; last three segments forming a broad, loose, compressed club, 

 subequal in length to one another, each with two small, round sensory 

 depressions on each surface, eighth and ninth subquadrate, truncate at 

 apices, tenth oblong, slightly narrower than ninth. Pronotum 

 strongly convex, truncate or emarginate in front, truncate at base, 

 dentate anteriorly, not transversely depressed behind anterior margin ; 

 sides not margined. Scutellum small, quadrate. Elytra strongly 

 convex, with or without costiform callosities on apical declivity. 

 Legs short, subequal in length; tibiae slightly expanded toward 

 apices, anterior pair dentate on exterior margins, each with a large, 

 arcuate spine at apex ; posterior tarsi as long as, or longer than tibiae, 

 apical segment of each shorter than preceding four segments united. 

 Anterior coxae contiguous. Middle coxae narrowly separated. Pos- 

 terior coxal cavities completely margined on first visible abdominal 

 sternite. Intercoxal process of abdomen tubular or narrowly tri- 

 angular. Body elongate, cylindrical. 



Genotype. — Bostryehus parallelus Lesne. (Present designation.) 

 Lesne ( 1899 ) erected this genus for 16 species without designating 

 a genotype. Of these species 8 are from the Old World, 1 from 

 Australia, 6 from South America, and 1 from North America. The 

 last species (/c>rfoVLeconte) was designated by Casey (1898) as the 

 genotype of his new genus Apatides.

 body rather densely clothed with short, recumbent, yellowish hairs.
