TETRAONYX.—EUPOMPHA. 393 
Morelia (Dugés®), 'Tacambaro in Michoacan, Mexico city, Jalapa (Hoge), Guanajuato ® 
(Sallé, Dugés*°, Hoge). 
A common species in Mexico, extending over the northern frontier into the United 
States and southwards into Guatemala. The variety femoralis has been received from 
two localities in company with the typical form, and I have not the slightest doubt that 
it is conspecific with it. Haag mentions* two other varieties :—(1) ‘‘ Capite nigro- 
lineato, thorace nigro-bimaculato, scutello apice nigro, femoribus anticis rufomaculatis ” ; 
(2) ‘*Capite nigro, post oculos rufomaculato; thorace bimaculato; scutello nigro.” 
In the male the anterior tarsi are dilated, and the basal joint is angularly produced 
within. 7. frontalis has much the facies of a large Pyrochroa. It may be easily distin- 
guished from 7. fulvus by the head being black in front, and by the more densely 
punctured opaque upper surface. 
EUPOMPHA. 
Eupompha, Leconte, Journ. Acad. Phil. 2nd ser. iv. p. 21 (1858) ; Leconte & Horn, Class. Col. 
N. Am. 2nd edit. p. 422 (1888). 
A single species only of this remarkable genus is known, peculiar to New Mexico 
and Texas, and the adjacent country to the southward. It has the vertex elevated 
and deeply cleft; and the lower portion of the tarsal claws shorter than the upper and 
connate with it. | 
An allied genus, Phodaga, Lec., containing a single species, P. alticeps, Lec., occurs 
in Arizona; it will probably be found eventually in Northern Mexico.

Hab. Norta America, Llano Estacado, Texas (?) 1, New Mexico ?.—Mexico, Coahuila 
(Dr. Horn), Villa Lerdo in Durango (Flohr *, Hoge). 
Found in some numbers by Hoge during his second Mexican expedition. ‘This insect 
has the thorax and elytra of a brilliant metallic bluish-green or golden-coppery colour, 
and the head in part and the legs ferruginous. Inthe male the three basal joints of the 
anterior tarsi are greatly swollen, convex beneath and deeply excavated above; these 
joints appear, at first sight, to have their under surface uppermost. Dr. Horn informs 
me that he has received specimens of E. fissiceps from Coahuila.
