94 HETEROMERA. 
hot region of the Pacific slope. E. dentipes is closely allied to E. griseus, from which 
it not only differs in its male characters, but in the finer and less rough punctuation of 
the upper surface, and less convex thorax. 
8. Evalces sinuatipes. (Tab. IV. fig. 24, ¢.) 
Elongate, narrow, testaceous or fusco-testaceous, sparsely pubescent, slightly shining. Head densely and rather 
coarsely punctured, the eyes black; antenne stout, testaceous; prothorax not very convex, somewhat 
flattened on the disc, densely, finely, and rather roughly punctured, the sides straight behind ; elytra finely 
and densely punctured; legs testaceous, comparatively stout; the anterior tibie slightly serrate within in 
their apical half, and the posterior tibie sinuate, in the male. 
Length (with the head extended) 34-33 millim. (¢ 2.) 
Hab. GuaTeMALA, Chiacam and San Gerdnimo in Vera Paz (Champion); Panama, 
Pena Blanca (Champion). 
Four specimens, two of each sex. Rather more depressed than F. griseus; the 
antenne and legs much stouter, the punctuation of the thorax and elytra finer, denser, 
and less rough; and the hind femora distinctly sinuate in the male. ‘The anterior tarsi 
are dilated in the male. The example from Chiacam, a female, has the thorax and 
elytra more densely punctured, but it is apparently referable to the same species, the 
sculpture also varying a little in the other specimens. 
4. Evalces luteus. 
Elongate, moderately narrow, luteous, sparsely pubescent, slightly shining; above finely and densely, the pro- 
thorax more roughly, the head more coarsely, punctured. Antenne varying in colour from fusco-testaceous 
to piceous with the two basal joints lighter; eyes black; prothorax large and convex, much rounded at 
the sides, narrowing from the base; beneath densely and finely punctured ; legs ferruginous. 
Length (with the head extended) 44 millim. ( 9.) 
fab. Muxico, Acapulco (Hége), Omilteme in Guerrero 8000 feet, Cuernavaca (/. H. 
Smith). 
Three examples, apparently all females. The individual from Omilteme is of a 
piceous-brown colour, but this is apparently due to discoloration. Much larger than 
. griseus, the elytra more finely and more densely punctured, the thorax convex 
and largely developed and with the sides much rounded. 
5. Evalces longulus. 
Elongate, narrow, fusco- or piceo-testaceous, sparsely pubescent, slightly shining; above very densely and 
very finely, the head more coarsely, punctured. Antenne ferruginous; eyes black; prothorax not very 
convex, the sides straight behind; elytra proportionately very long; legs ferruginous; beneath densely 
punctured; central sheath of the cedeagus of the male slender and narrowing towards the end. 
Length (with the head extended) 33 millim. (<¢.) 
Hab. Mexico, Guanajuato (Sallé). 
Two examples, one of which is a male. Narrower and smaller than £. luteus; the 
thorax more finely and still more densely punctured and rather less convex. Larger
