1912] Wolcolf—The Cleridce of the Stanford Expedition 75 



Head finely, densely, rugosely punctate, black, front red. Antennae with joints 

 1, 6, 7, 8, and 11 yellowish white; joints 2, 3, 4, and 5 rufo-piceous; joints 9 and 

 10 fuscous. Thorax finely, rugosely punctate; color black, anterior and posterior 

 margins pale testaceous. Elytra rather coarsely, very vaguely seriate-punctate; 

 color black with a large, longitudinal maculation starting at the base (where it occu- 

 pies all the space between scutellum and tlio humeri) and extending to basal 

 fourth, a median and a subapical fascia, both of which are interrupted at the 

 suture and do not attain the flanks, yellow. Abdomen piceous, two or three 

 basal segments red. Legs yellow, sparsely pubescent. 



To judge by the descriptions of E. sexplagiatus Kuw., and 

 E. parvulus Schklg. (no specimens of either being available for com- 

 parison), the new species api>ears to be an intermediate form, but 

 still entitled to specific rank. E. iracundus difl^ers from both the 

 above mentioned species in elytral sculpture, manner and form 

 of the markings, and the color of the antennae and the abdomen. 

 From E. sexplagiatus it differs further in having the front and hind 

 margins of the pro thorax pale. In E. parvuliis the hind legs are 

 largely black, not entirely pale yellow as in the present species.

This is an extremely ^'ariable species and one of very wide dis- 

 tribution. The original types of the species came from Para, 

 Brazil ; the species is now known from other places in that country 

 (Jatahy, Amazon and Itaituba). There are also records showing 

 it to occur in southern Peru. (Vilcanota), French Guiana, Vene- 

 zuela, Colombia, Nicaragua, Guatemala and Mexico. 



Three specimens before me are all from Madeira-Mamore R. R. 

 Camp No. 43 and vary but little inter se. Two of the specimens 

 are typical in every detail except that the scutellum is not "albi- 

 dum," but fuscous, being concolorous w^ith the elytra. The other 

 specimen has the vertex (as well as the front) of the head very 

 white, the sutural margin of the elytra less distinctly bordered 

 with pale color, the abdomen entirely pale yellow, and the tibiae 

 and tarsi totally fuscous.
