ECTRICHODIA. 225 
It is probable that the eyes in the male will be found to vary in size in different 
individuals of the same species. The antenne are apparently 8-jointed, the usual third 
joint being divided into two, and the fourth joint into four.

Capetillo (Champion); Nicaragua, Chontales (Janson); Costa Rica (Van Patten); 
Panama (Boucard). 
A very variable and widely-distributed species. In fresh examples the head, except 
at the sides behind the eyes, the pronotum, the base of the elytra, and the connexivum 
in great part, are bright sanguineous, this colour fading to testaceous. The pronotum 
in some specimens has the transverse sulcus, and also the longitudinal one, more or less 
spotted or marked with black (crucifera, Stal). The females sometimes have a large 
black patch on each of the connexival segments; this form has only been seen from 
Chontales. The legs are constantly black or piceous. The venter in some examples is 
spotted or fasciate, in others in great part sanguineous, or entirely black. The name 
crudelis being preoccupied in Ectrichodia in the wide sense, it was subsequently changed 
by Stél; but as this genus is now restricted to a few American forms, this alteration 
becomes unnecessary. Stal’s and Walker’s types have been seen. The specimens before 
me vary from 123-21 millim. in length, and from 5-9 millim. in breadth. A typical 
male from Panzos and a female of the var. crucifera from Teleman are figured. 
2. Kectrichodia cinctiventris. (Tab. XIII. fig. 20, head of the 3.) 
Ectrichodia cinctiventris, Stal, Enum. Hemipt. ii. p. 103+; Uhler, Bull. U.S. Geol. & Geogr. Surv.

Hab. Nortu America, Texas! ? (Mus. Brit.), New Mexico 2 MEXICO (Mus. Vind. 
Ces.), Teapa in Tabasco (H. H. Smith), Temax in N. Yucatan (Gaumer). 
I have seen nine specimens of E. cinctiventris, including one of the types, all males. 
It is perhaps an extreme form of the very variable EZ. crudelis, from which it differs in 
having the eyes larger and more prominent in the male, and the sides of the head a 
little more rapidly converging behind in this sex.
