Olivier (1795) described Bostrichm longicornis collected on dead 

 wood in Santo Domingo by Palisot-Beauvois. Horn (1878) described 

 Tetrapriocera schwarzi from a specimen collected by E. A. Schwarz at 

 Capron, Fla., and another on which he erected his new genus Tetrapri- 

 ocera, from W. M. Gabb from the Island of Santo Domingo. Gorham 

 (1883) placed schwarzi Horn as a synonym of longicornis Olivier. 

 Dejean (1835) listed Apate rufescens from Brazil without giving any 

 description. Lesne (1901) associated Apate tridens Fabricius ( 1792) 

 with Tetrapriocera longicornis (1795), placing the latter species as a 

 synonym of tridens. However, after Henriksen examined the type of 

 tridens and found it to be probably the same as the species described 

 by Fabricius (1801) under the name of torquata, Lesne restored longi- 

 cornis Olivier for this species.

Xylopertha Casej T , 1898 (not Guerin-Meneville 1845), N. Y. Ent. Soc. Jour. 6: 

 66, 67. 



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

 strongly transverse, sinuate in front ; labrum transverse, short, truncate 

 and densely ciliate with long, yellowish hairs in front ; mandibles more 

 or less attenuate towards apices; eyes small or large, oval, globose, 

 strongly projecting. Antenna short, 9-segmented; first and second 

 segments robust, first elongate, arcuate, flattened on underside, second 

 quadrate or oval, much shorter than first; third to sixth short, trans- 

 verse, compact, united, shorter than first ; last three segments forming 

 a large, loose, compressed club, each with a number of small sensory 

 depressions on each surface, the seventh subtri angular, eighth broadly 

 oblong, and ninth narrowly elongate, narrower and longer than eighth. 

 Pronotum strongly convex, broadly, arcuately emarginate in front, 

 truncate at base, dentate anteriorly, not transversely depressed behind 

 anterior margin, sides not margined. Scutellum small, longer than 

 wide. Elytra strongly convex, with or without tubercles on anterior 

 margin of apical declivity and on thickened sutural margins. Legs 

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

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

 tarsi as long as, or longer than, preceding four segments united. An- 

 terior coxae contiguous. Middle coxae narrowly separated. Inter- 

 coxal process of abdomen lamellate. Body elongate, cylindrical. 



Genotype. — Apate chevrieri Villa. (Present designation.) 



Casey (1898) transferred the three American species (suturalis, 

 declivis, and bidentata) from Sinoxylon to Xylopertha Casey (not 

 Xylopertha Guerin-Meneville). Lesne (1901) erected Scobicia for 

 eight species, five from Europe and three from America, without desig- 

 nating a genotype. 



There are scarcely any useful secondary sexual characters for sepa* 

 rating the sexes in any of the species of this genus. The females 

 usually have the last visible abdominal sternite a little more deeply 

 emarginate at the apex than the males, and the lateral grooves nearly 

 obsolete.
