CONIBIUS.—ULUS. 133 
punctured ; the prothorax broader and more transverse, the anterior angles subacute, the hind angles 
subrectangular, the apex more distinctly emarginate ; elytra as in NV. rugyes; slightly larger and broader 
in form. 
Length 6-7 millim. (¢ 2.) 
Hab. Mexico, Tehuacan (Hoge). 
Two examples. Found in company with WV. rugipes.

Ten. N. A. p. 350; Lec. & Horn, Class. Col. N. A. p. 379. 
Three species of this genus are known from California; we now add another from 
Mexico and Guatemala. 
1. Conibius brunnipes. (Tab. VI. fig. 12.) 
Heterophaga brunnipes, Sturm in litt. 
Elongate oval, subparallel, convex, black, rarely reddish brown, shining, glabrous. Head closely but not very 
coarsely punctured; prothorax broader than long, broadest before the middle, the sides rounded ante- 
riorly, slightly narrowing behind, and feebly sinuate just before the base, the anterior angles obtuse, 
the hind angles subrectangular, apex feebly emarginate, the base subtruncate, lateral margins distinct, 
very closely and finely punctured, the punctures separate on the disc and slightly confluent at the 
sides ; elytra scarcely wider than the prothorax, the base subtruncate, finely, narrowly, and very shallowly 
punctate-striate, the striz: more or less interrupted, the interstices flat and very closely and finely punc- 
tured; legs robust. Beneath slightly shining, the ventral surface finely and sparingly muricate-punctate ; 
intercoxal process narrow, the apex rounded. 
Length 5-53 millim. (¢ 92.) 
Hab. Mexico (coll. F. Bates, Sallé ex coll. Sturm), Yolos, Puebla, Guanajuato, 
Capulalpam (Sal/é), Tehuacan, Oaxaca (Hége); GuaTEMa.a, near the city (Salvin), El 
Jicaro (Champion). 
Not uncommon in Mexico. Allied to C. seriatus, Lec., from the Colorado Desert, 
but larger, the thorax more distinctly margined at the sides, the elytra differently 
sculptured, and the legs stouter. Specimens occasionally occur with the suture reddish, 
or entirely reddish-brown in colour. 
ULUS. 
Ulus, Horn, Rev. Ten. N. A. p. 358; Lec. & Horn, Class. Col. N. A. p. 879 (1883). 
Two species of this genus have been recorded from California; others are found in 
Central America, the genus ranging as far south as Panama. The different species are 
found beneath stones, both on the coast and inland. 
1. Ulus hirsutus. (Tab. VI. fig. 13.) 
Ovate, convex, brownish black, with an neous tinge, densely clothed with rather coarse cinereous, golden, or 
brownish recumbent hairs. Head very closely, rather coarsely, and almost confluently punctured ; pro- 
thorax broadest at the base, feebly rounded at the sides, narrowing anteriorly, strongly transverse in the
