coarse longitudinal wrinkles, the rest with scattered not very fine punctures; the two basal joints of the 
antennz sometimes red. 
Length 83-10 millim. (¢ 9.)

Numerous examples. Apparently a widely distributed and not uncommon species 
in Tropical South America; one example only from Mexico. Examples of this species 
contained in Mr. F. Bates’s collection bear various MS. names. The example from 
Mexico, a male, is figured. 
ANTIMACHUS. 
Antimachus, Gistl, Isis, 1829, Heft x. p. 1055, t. 3. figg. A,a; Lacordaire, Gen. Col. v. p. 330. - 
Ceratupis, Perty, Del. Animal, art. Brasil, p. 57. | 
This is a genus containing some few Tropical American species, one of which is. 
found in Nicaragua. The range of Antimachus is from Nicaragua to Brazil. An 
allied genus, Metabolocerus, F. Bates, is found in Colombia. |

ULOMA. 
Uloma, Castelnau, Hist. Nat. ii. p. 220 (1840); Lacordaire, Gen. Col. v. p. 332. 
This is perhaps the most widely distributed genus of the Tenebrionide, and found. 
in almost all the warmer parts of both the Old and the New Worlds, and also in 
Australia; it is well represented in Central America by seven species. 
Uloma will doubtless eventually have to be divided when the numerous undescribed. 
tropical species are worked out. ‘The different species are found beneath bark. 
1. Epipleure eatending to the apex of the elytra,

+ Lacordaire places this species in Antimachus, though he calls especial attention to the external armature. 
of the tibiz ; possibly, however, he may have had some other insect in view.
