90 HETEROMERA. 
Oblong ovate, black, shining. Head with some scattered fine punctures, the vertex smooth; prothorax trans- 
verse, subcordate, distinctly margined, moderately convex, strongly rounded at the sides, constricted 
towards the base, feebly emarginate in front, anterior angles rounded or obtuse, hind angles obtuse and 
indistinct, smooth or with very fine scattered punctures; elytra gradually widening and rounded from the 
base to the widest part about the middle, somewhat convex, the humeri rounded and not prominent, the 
sculpture varying very much, smooth with scattered very fine punctures and without any trace of stria, 
shallowly punctate-striate and the interstices with scattered punctures, or coarsely, shallowly, and irre- 
gularly punctate-striate, the interstices coarsely punctured, and the punctures often confluent ; anterior 
femora unarmed in both sexes; spurs of anterior tibia subequal; the basal joints of the anterior tarsi in 
the male thickly clothed with hair beneath. 
Length 13-20 millim. (3 9.) 
Hab. Mexico (coll. F. Bates), San Andres, Guanajuato (Sallé), Tehuacan (Hége). 
Var. a. Elytra shallowly sulcate, the striz with shallow not very coarse punctures, the interstices finely and 
sparingly punctured. 
Hab. Mexico, San Andres (Sallé), Tehuacan, Jalapa (Hoge). 
Var. b. Smaller, the thorax a little less constricted behind, the sculpture of the elytra varying as in the 
type. 
Length 15-16 millim. 
Hab. Mexico, Las Vigas, Jalapa (Hége). 
A species varying very much not only in size, but in the shape of the thorax and 
elytra; the thorax is a little more convex, more strongly rounded at the sides, and 
more constricted at the base, the anterior angles a little more rounded and less pro- 
minent, and the anterior margin straighter than in the specimens I refer to Z. distincta, 
Sol.; the elytra vary exceedingly in sculpture, in some specimens almost rugulose, the 
interstices almost as coarsely punctured as the strie, and the punctures frequently 
confluent, in other examples almost smooth and with the strie almost obsolete; the 
interstices, however, are never transversely or obliquely wrinkled as in E. distincta, nor 
the humeri so distinct as in that species. 
The var. 6, though differing somewhat from £. sal/wi in the shape of the thorax, is 
probably merely a form of that species.

Hab. Mexico *? (coll. F. Bates), Puebla, Toluca, San Andres, Oaxaca (Sallé), Tehu- 
acan, Oaxaca (Hoge). 
A dull subopaque species closely allied to EZ. sallei. The thoracic hind angles 
acute; the elytra a little more narrowed towards the base, and the greatest breadth 
behind the middle, and in this respect approaching EZ. levigata and E. tenebricosa.
