oblong, subequal in length to and narrower than ninth. Pronotum 

 strongly convex, emarginate in front, truncate at base, dentate anter- 

 iorly, not transversely depressed behind anterior margin; sides not 

 margined. Scutellum small, quadrate. Elytra strongly convex, with- 

 out tubercles or costif orm callosities on apical declivity. Legs, short, 

 subequal in length ; tibiae slightly expanded toward apices, dentate on 

 exterior margins ; each with a large, arcuate spine at apex ; posterior 

 tarsi usually as long as, or longer than tibiae, apical segment of each 

 shorter than preceding four segments united. Anterior coxae con- 

 tiguous. Middle coxae rather broadly separated. Posterior coxal 

 cavities completely margined on first visible abdominal sternite. 

 Intercoxal process of abdomen tubular or narrowly triangular. Body 

 elongate, cylindrical. 



Genotype. — Amphice?*as fortis LeConte. (Original designation.) 

 Casey (1898) erected Apatides for Amphicerus fortis LeConte, Api- 

 tides robustus new species, and Apatides pimcticeps new species, and 

 designated fortis as the genotype. Lesne (1898) erected Bostrychopsis 

 for 16 species without designating a genotype. He divided his genus 

 into 6 groups, of which group VI included only fortis LeConte. 

 Lesne (1900) stated that the paper by Casey had priority over his 

 'paper, but used Apatides only for group VI of his Bostrychopsis, and 

 retained Bostrychopsis for the other 5 groups.

Male. — Black, with a slight reddish tinge, underside of body some- 

 times more reddish, the palpi and antennae brownish yellow; dorsal 

 surface of body glabrous. 



Head much narrower than pronotum, coarsely, sparsely punctate 

 anteriorly, smooth and shining in transverse concavity, with short, 

 longitudinal, parallel costae on occiput; clypeus coarsely, rather 

 densely punctate, anterior angles rectangular. 



Pronotum quadrate, strongly convex, widest near middle, strongly 

 deflexed on apical half; sides broadly rounded, more strongly con- 

 verging anteriorly, produced into a large unciform horn at apical 

 angles; posterior angles rectangular, or obtusely rounded; surface 

 rugose or coarsely, deeply punctate at sides, with large scalelike 

 granules on disk, the granules flattened on basal half, larger, semierect, 

 and more tuberculate on apical half, and with a number of broad, 

 rasplike tubercles on each side in front of middle. 



Elytra at base subequal in width to pronotum at middle, slightly 

 sinuate at base, without longitudinal costae ; lateral and sutural mar-
