In this species the body is black, the elytra are uniformly sanguineous, and the head 
has a rufous spot on the front. In the male, joints 4 and 5 of the antenne are much 
thickened, 5 being distorted and produced on its upper side; the basal joint of the 
middle tarsi is widened internally ; and the sixth ventral segment is depressed in the 
middle, and very feebly emarginate at the apex. The outer spur of the hind tibie is 
very broad, spoon-shaped, the inner one slender. Dugés? also gives Vera Cruz (Sallé) 
as a locality, but perhaps in error.

We have received sixteen examples of this species. It has the body black, the head 
and thorax rufous, the anterior portion of the former and two spots on the disc of the 
latter black. ‘The thorax is deeply transversely depressed before the middle. In the 
male, joint 4 of the antenne is much thickened, 5 is strongly acutely produced on the 
upper side, and 6-10 are subequal ; the anterior femora are angularly dilated on the 
inner side at the middle; the intermediate femora are flattened and dilated, slightly 
concave beneath ; the basal joint of the intermediate tarsi is greatly dilated within ; 
and the sixth ventral segment is depressed and smooth in the middle, and feebly 
emarginate at the apex. The discal spots on the thorax vary in size, and in one 
specimen they are almost obliterated. ‘The outer spur of the hind tibiz is very broad, 
the inner one slender. 
4. Cantharis mutilata. 
Cantharis (Lytta) mutilata, Horn, Trans. Am. Ent. Soe. v. p. 155°, and x. p. 310. 
Hab. Nortu America, Arizona !.—Mexico, Monclova in Coahuila (Dr. Palmer), 
Villa Lerdo in Durango (Hége). 
Of this species we have received ten examples, one only of which is of the male sex. 
As Dr. Horn states (Trans. Am. Ent. Soc. xii. p. 108), C. mutilata is allied to C. ery- 
throthorax, but differs from it in the entirely rufous thorax, as well as by its male
