86 HETEROMERA. 
29. Eleeodes chihuahuensis. (Tab. IV. fig. 14, 2 .) 
Elongate oval, not very convex, subopaque, black. Head somewhat coarsely and closely punctured ; prothorax 
a little broader than long, feebly convex, subquadrate, widest a little before the middle, slightly narrowed 
towards the base, sides feebly rounded and slightly sinuate near the angles, distinctly margined, anterior 
angles almost rounded, hind angles obtuse, with a distinct fine scattered punctuation; elytra dull, the 
disc depressed, widest a little behind the middle, somewhat abruptly narrowed just before the base, the 
apex slightly produced and rounded, humeri obtuse, the base raised in the middle, with rows of fine 
punctures, the interstices flat and each with a row of punctures almost as coarse as those of the striz ; 
anterior femora unarmed; anterior tarsi clothed with short stiff hairs beneath; spurs of the curved 
anterior tibia subequal; progsternum produced behind into a short horizontal projection. 
Length 184 millim. (9.) 
Hab. Maxico, Pinos Altos in Chihuahua (Buchan-Hepburn). 
One example. This species is not very closely allied to any other here recorded. 
2. The basal joints of the anterior tarsi in the male densely clothed with finer (almost 
silky) hair beneath, rarely feebly dilated. (Buapyis, Horn.) 
A. Anterior femora toothed in the male. 
a. Elytra feebly caudate at the apex. 
80. Eleeodes spinole. 
Eleodes spinola, Sol. Studi Ent. p. 2531. ; 
Hab. Mexico!, Toluca (coll. F. Bates), Yolos, Puebla, Oaxaca, Cuernavaca, Guana- 
juato (Sadlé), Jalapa, Oaxaca (Hoge), Monclova in Coahuila (Dr. Palmer). 
31. Eleodes calcarata. (Tab. IV. fig. 15.) 
Eleodes calcarata, Sturm, in litt. 
Allied to E. spinole, and differing as follows:—Shining and more convex; the prothorax less transverse, 
narrower, a little more convex, smooth, and almost impunctate ; the elytra more convex, with shallow or 
obsolete grooves, and scattered fine punctures, sometimes finely and shallowly punctate-striate ; anterior 
femora toothed in the male. 
Length 18-19 millim. (¢ 2.) 
Hab. Mexico, Guanajuato (Sallé, ex coll. Sturm). 
Five examples. 
32. Elesodes montana. 
Allied to EZ. spinol, and differing as follows :—A little more shining, and more convex; the prothorax more 
convex, smooth, or finely and sparingly punctured ; the elytra somewhat coarsely and shallowly punctate- 
striate, the interstices rather coarsely, and sometimes muricately, punctured, the apex feebly caudate and 
almost rounded; anterior femora toothed in the male. 
Length 17-19 millim. (¢ 9.) 
Hab. Mexico, Alvarez Mountains (Dr. Palmer). 
Six examples. This is perhaps a form of EF. spinole.
