According to Capt. Casey, E. quadricollis, Mann., and E. vicina, Lec., are distinct 
species, the former occurring in the vicinity of San Francisco and the latter inhabiting 
the Gila valley. 
Elzodes alutacea (p. 80). 
To the Mexican localities given, add :—Villa Lerdo in Durango, Cholula, Matamoros 
Izucar, Atlixco, Amecameca, Salazar, Mexico city (Hége). 
The typical form of this very variable species has been received in plenty from 
Toluca; the coarsely punctured form (?) (£. maillei) in numbers from various places in 
the State of Puebla. 
13 (a). Elwodes polita. 
Black, shining, elongate-oval, narrow (¢ ), broad-oval and comparatively short (@). Head somewhat closely, 
moderately finely punctate ; prothorax transversely subquadrate, widest at one-third from the apex, the 
sides strongly rounded anteriorly and obliquely converging behind, the base and apex equal in width, the 
anterior angles obtuse, the hind angles subrectangular (obtuse in some specimens), the lateral carina 
sharp, the surface very finely, sparsely punctate ; elytra oblong-oval ( ¢), broad-oval and flattened on the 
disc (2), with rows of rather coarse, not very closely placed punctures, the interstices strongly convex, 
each with an irregular row of fine, widely separated punctures; beneath shining, with a few scattered 
fine punctures ; prosternum declivous behind, sulcate in front; anterior femora stout, feebly emarginate 
on the inner side before the apex; anterior tarsi clothed with spiny hairs beneath; anterior and inter- 
mediate tibiw slightly curved in the male, the upper spur of the anterior pair much longer and stouter 
than the lower one in the female ; first ventral segment depressed in the middle behind in the male. 
Length 11-13, breadth 43-64 millim. (¢ 92.) 
Hab. Mexico, Salazar, Huitzilac (Hége). 
Sent in abundance by Hoge. ‘This is probably an extreme varietal form of E. alu- 
tacea, from which it differs in the strongly convex elytral interstices. The punctures 
of the elytral series are rather coarse and deep, not very closely placed. The female is 
comparatively short, very much wider than the male. 
13 (zs). Elewodes segregata. 
Dull black, elongate-oval, narrow (3), broad-oval (2). Head sparsely, finely punctate; prothorax broader 
than long, feebly transversely convex, subquadrate, rounded at the sides anteriorly and slightly sinuous 
before the base, the base and apex about equal in width, the anterior angles obtuse, the hind angles sub- 
rectangular, the surface exceedingly minutely, sparsely punctate; elytra flattened on the disc anteriorly, 
oblong-oval in the male, very much broader in the female, slightly emarginate at the base, and with the 
apex rather broadly produced, the humeri somewhat prominent but obtuse, the surface with rows of fine, 
shallow, distantly placed punctures, the interstices each with a single row of very minute punctures ; 
beneath shining, the ventral surface longitudinally wrinkled and with widely scattered fine punctures ; 
prosternum slightly produced, abruptly declivous behind, suleate in front; anterior tarsi clothed with
