SPONDYLIS.—TRISTACHYCERA. 15 
1. Spondylis mexicanus. 
Sp. upiformi affinis. Elongatus, angustus, niger subnitidus, densissime (supra scabrose) punctatus, elytris 
exceptis erecte nigro-setosus ; thorace ovato, subcordato, postice gradatim recte angustato, angulis posticis 
haud productis; elytris utrinque sutura et costis quatuor (apicem fere attingentibus) elevatis ; tibiis latis, 
compressis, calcaribus posticis latis, obtusis. 
Long. 103 lin. 
Hab. Mexico, near the capital (Flohr). 
Distinguished from the Boreal-American species S. upiformis by its larger size and 
the quadricostate elytra. The thorax, too, is somewhat different in form, the sides being 
straight and not sinuate before the hind angles, and the latter not being prominent. The 
form of the legs and the spurs of the hind tibie is similar in both species. 
CRIOCEPHALUS. 
Criocephalus, Mulsant, Coléop. Fr. Long. ed.i. p. 63 (1839). 
The species of this genus, eleven in number, are restricted, like Spondylis, to the nor- 
thern parts of the eastern and western hemispheres, one only having been found beyond 
the temperate zone, in Mexico, where it occurs in pine-forests at the higher elevations. 
1. Criocephalus mexicanus. 
Criocephalus mexicanus, Thoms. Class. Long. p. 260. 
Hab. Muxico, near the capital (Flohr). 
MALACOPTERUS. 
Malacopterus, Serv. Ann. Soc. Ent. Fr. 1833, p. 565. 
Ganimus, Leconte, Smithsonian Misc. Coll. part i. Long. p. 173. 
Exclusively American. Five species have been described, ranging from California to 
Tucuman. I judge Ganimus (Lec.) to be synonymous from the excellent description, 
which fits well the species allied to MZ. lineatus. 
1. Malacopterus lineatus. (Tab. III. fig. 17.) 
Malacopterus lineatus, Guérin, Icon. R. An. ii. p. 222°. 
Hab. Nicaracua, Chontales (Belt, Janson).—CoLomBia!; VENEZUELA; AMAZONS. 
2. Malacopterus mexicanus. 
Malacopterus mexicanus, Thoms. Class. Long. p. 248. 
Hab. Mzxxtoo. 
Very closely allied to, if not identical with, I/, lineatus. 
TRISTACHYCERA. 
Tristachycera, Bates, Trans. Ent. Soc. 1872, p. 170. 
One species only is known.
