214 HEMIPTERA-HETEROPTERA. 
Two males and one female are referred to this species, the female nearly agreeing 
with one of Stal’s specimens of the same sex from Surinam in the Stockholm Museum. 
The males have more slender legs than the females, and the eyes a little larger and 
more prominent. The wings are whitish. In WM. picipes* and M. abdominalis 
(Herr.-Schaff.) the eyes are smaller and more widely separated in the males. St&l’s 
types of MM. picinus and M. picicornis have been seen. M. (Pirates) degener, Walk., 
is a close ally of M. morio.

This insect is treated by Stal as a colour-variety of MW. picipes (Herr.-Schaff.), and 
by Prof. Uhler as a distinct species. ‘The last-mentioned authority states that both 
sometimes occur under the same stone,

A Tropical-American genus, with one or two representatives extending northwards 
into the United States. Upwards of twenty different species are enumerated by 
Lethierry and Severin, but many of the names are mere synonyms or wrongly placed 
under Rasahus t+. These insects, owing to their large size and conspicuous markings 
seem to have been great favourites with collectors. Eight species are here recorded 
from Central America, one of which is treated asnew. The synonymy of most of them 
is much involved, Walker having described many previously known forms under 
new names. 
a. Head (except in front) and pronotum with long scattered hairs only. 
a', Pronotum almost smooth, the anterior lobe with the median sulcus 
only distinct, the other sulci obsolete, except at the sides in front ; 
elytra with the base and apex of the corium broadly, a common 
patch adjoining the apex of the scutellum, a transverse mark a 
* Reduvius pungens, Lec., is synonymous with this species.
