so; maxillary palpi stout, black, the apical joint oblong-ovate, obliquely truncate at the tip; antenne 
black, stout, filiform, the joints flattened-cylindrical and not tapering outwardly—1 and 3 about equal 
in length, 2 short, not half the length of 3, 4-10 subequal, much shorter than 3, 11 longer than 10; pro- 
thorax rather longer than broad, narrower than the head, campanulate, slightly dilated at the base, densely, 
rather coarsely punctate (the punctures here and there confluent and very much coarser than those on the 
head), and finely canaliculate; elytra elongate, broader than the prothorax, shallowly and thickly punc- 
tured ; legs stout, comparatively short, the tarsi especially, the spurs of the hind tibiz subequal ; anterior 
tibiee with a single spur in the male. 
Length 10 millim. (¢.) 
Hab. Mexico, Amula in Guerrero 6000 feet (H. H. Smith). 
Though we have received but a single ( ¢ ) example of this species, it is advisable to 
name it. In having a single spur to the male anterior tibia and filiform antenne, 
E. unicalcarata approaches E. horni (vicina, Dugés), from which its longer, more 
coarsely punctured, thorax, larger eyes, and stouter antenne distinguish it at a glance. 
The pubescence is sparse, and does not hide the punctuation; the punctures on the 
head are fine and sparse, those on the thorax much coarser and more closely placed ; 
the legs and antenne are stout and comparatively short. 
The dissimilar punctuation of the head and thorax (resembling that of the 
N.-American £. trichrus, Pall.), apart from other characters, will separate EF. unical- 
carata from LE. stigmata, FH. cinerea, &c.

Apparently a common species in Mexico, whence we have received a large number 
of specimens from various widely-separated localities, and extending southwards to the 
Los Altos region of Guatemala. It varies in the number and size of the denuded spots 
on the upper surface. In the typical E. maculata (Say) (as in E. ocellata, Dugés) the 
elytral spots are numerous and comparatively large; in the var. conspersa, Lec. 
(= punctuata, Dugés), they are smaller and more scattered; and in the var. media, Dugés,
