A single female specimen, differing from E. octomaculata in its larger size, stouter 
build, and coarser sculpture, is, no doubt, referable to E. rubropicta (Perty). 
7. Emenadia pectinata. (Tab. XVI. fig. 11, 4, var.)

A male from Mexico and a pair from Guatemala agree with Dr. Horn’s description 
of Lf. pectinata: they have the under surface more sparsely punctured than in £. octo- 
maculata. In the two males the elytra are yellow, with the base, a median lateral 
spot, and the apex black ; in the female the elytra are black and the abdomen is red. 
The median lobe of the thorax is transversely notched at the tip. The second joint of 
the hind tarsi is broadly dilated, shorter than the third. | 
This extremely variable species seems to have been described under no less than 
fifteen different names. 
8. Emenadia cruenta. (Tab. XVI. fig. 12, 2.) 
Rhipiphorus cruentus, Germ. Ins. Spec. nov. p. 168 (1824)*; Gerst. Rhipiph. Col. Fam. Disp. Syst.

Hab. Norra America 12, Georgia to California ®, San Diego 4—Mex100 2, Guanajuato 
(Sallé). 
One female example from Guanajuato, agreeing with Dr. Horn’s description *. It is 
black, with the abdomen and elytra rufous, the latter with the base narrowly, and the 
apex broadly, black ; the median lobe of the thorax is not notched at the tip; the 
second joint of the hind tarsi is slender, much longer than the third.
