Mineral del Cedro *, Guanajuato 4 (Dugés), State of Vera Cruz (Flohr 4). 
A large velvety-black, robust species, the pubescence above and beneath black ; 
the thorax a little broader than long; the anterior tibie with two spurs in the male. 
Dr. Horn (Trans. Am. Ent. Soc. xii. p. 107) has identified Dugés’s species with that of 
Leconte: Dugés* demurs to this, nevertheless Mexican specimens do not differ in the 
slightest from a Texan example of EL. corvina now before me.

Hab. Nortu AmeErica!?5, Middle States? to Texas? ®.—Merxico, Monclova in 
Coahuila (Dr. Palmer), Huasteca de San Luis Potosi (Dugés®), Villa Lerdo in Durango 
(Hoge). 
Found in plenty by Herr Hoge at Villa Lerdo. As Dugés remarks, this species 
may be known from &. corvina (=nigerrima, Dug.) by its smaller size and by the outer 
spur of the posterior tibiz being spoon-shaped and much broader than the inner one. 
Durango specimens agree perfectly with others from Texas before me. This insect is 
of a uniform black colour, with black pubescence, the upper surface very densely, finely 
punctured, the antenne setaceous.
