setiferous ones; beneath shining, sparsely punctured ; legs black or piceous, the basal half of the femora

Hab. Mexico, Temax in N. Yucatan (Gawmer); Guaruma.a, Zapote, Las Mercedes 
(Champion); Nrcaraeua, Chontales (Belt, Janson); Panama, Bugaba, Tole (Champion). 
Numerous examples. This species resembles the Colombian L. denticollis, Makl., in 
the shape of the thorax and other particulars, but has the joints 4-11 of the antenne 
in the male widened and flattened; in the last-named character L. scapularis approaches 
the genus Prostenus. The elytra are coloured as in the undescribed L. humeralis of 
South America. 
XYSTROPUS. 
Xystropus, Solier, Ann. Soc. Ent. Fr. iv. p. 241 (1835); Lacordaire, Gen. Col. v. p. 515 (1859). 
This genus is peculiar to Tropical America. Thirteen species have been described, 
and numerous others are enumerated in Gemminger and Harold’s catalogue; three of 
the former extend northwards into the Central-American region. These insects are 
found upon bushes on the savannas of the low country, and are usually common where 
they occur.

This insect is abundant in the State of Panama. It varies in colour from a bright 
metallic golden-green with cupreous tints to fiery cupreous, and in length from 8-10 
millim. The Mexican locality requires verification.
