Head strongly convex, not transversely depressed behind eyes, 

 deeply inserted in prothorax, not visible from above; clypeus flat, 

 strongly transverse, broadly, arcuately emarginate in front, anterior 

 angles acute or rectangular; clypeal suture distinct or obsolete; labrum 

 short, strongly transverse, truncate and densely ciliate with long, yel- 

 low hairs in front ; margins of buccal cavities not dentate below eyes ; 

 mandibles more or less attenuate toward apices ; eyes small, transverse, 

 oval, strongly projecting. Antenna short, 9- or 10-segmented ; first 

 and second segments robust, first oblong, second oval, shorter than 

 first; third to sixth or seventh short, oval or transverse, narrower 

 than second, subequal in length to one another; last three segments 

 forming a broad, rather compact, compressed club, subequal in length 

 to one another, each with two round sensory depressions on each 

 surface, first and second segments of club transverse, truncate at 

 apices, apical segment oval. Pronotum strongly convex, strongly de- 

 clivous and dentate anteriorly, subtruncate in front, truncate at base, 

 not transversely depressed behind anterior margin; sides not mar- 

 gined. Scutellum small, quadrate. Elytra strongly convex, without 

 longitudinal costae on disk or tubercles and costiform callosities on 

 apical declivity; truncate at base. Legs short, subequal in length; 

 tibiae slightly expanded toward apices, 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. Posterior coxal cavities completely margined on first visi-

 narrowly triangular. Body elongate, cylindrical. 



Genotype. — Of Micrapate and Bostrychulus, Sinoxylon dinode- 

 roides Horn. (Present designation.) 



This genus is widely distributed and is found in the southern part 

 of the United States, the West Indies, Mexico, Central and South 

 America, Africa, and the Mediterranean region and at present con- 

 tains at least 35 described species. 



Casey (1898) erected the genus Micrapate for Sinoxylon dinode- 

 roides Horn, Micrapate cristicauda new species, and Sinoxylon sim-
