162 HEMIPTERA-HETEROPTERA. 
Hab. Guatemata, Volcan de Fuego 6400 feet (Salvin), Quezaltenango 7800 feet 
(Champion). : 
_ Two examples, both in a bad state of preservation, the one from Quezaltenango 
being without head. This insect is very like H. culicis, but apparently belongs to a 
different species: it is more robust, the legs are stouter, the anterior femora and tibie 
being much more thickened, the median lobe of the pronotum is relatively longer and 
broader, and the antenne are a little less slender. The Quezaltenango specimen has 
the anterior legs enormously developed, with the tarsal claws very elongate. The 
elytra and wings are creased and mutilated in both examples. | 
6. Henicocephalus culicis. (Tab. X. fig. 6.) 
Hymenodectes culicis, Uhler, Trans. Maryland Acad. Sci. 1892, p. —'. 
Enicocephalus (schwarzii, Ashm. MS.) culicis, Ashm. Proc. Ent. Soc. Wash. il. p. 829 (Dec. 1892)’. 
Hab. NortH America, Utah 12,—Merxico (ex C. F. Baker), Omilteme in Guerrero 
8000 feet (H. H. Smith). 
The three Mexican specimens referred to this species, one of which has been 
| received from Mr. C. F. Baker under the above name, agree very well with 
Mr. Ashmead’s description. The insect is very like H. angustatus. It has the elytra 
subhyaline and iridescent, with the discal cell open, the scutellum longitudinally 
carinate at the apex, the joints 2-4 of the antenne long and very slender, the 
posterior lobe of the pronotum * shallowly emarginate behind, the posterior lobe of 
the head smooth and subglobose, the ocelli prominent, and the lower anterior tarsal 
claw shorter than the upper one. JH. culicis appears to be known from various other 
localities in the United States f. | 
Fam. REDUVIIDZE. 
Subfam. HMESINA. 
The species of this subfamily of Reduviide are easily recognizable by their raptorial 
front legs, with very elongate cox; the head is without ocelli. In some of the 
genera the anterior tarsi are long, rigid, and claw-like, with the joints fused into one. 
Ghilianella and Ploiaria (Cerascopus) are completely apterous. All are very slender, 
elongate insects. _ | 
The systematic arrangement adopted here is a little different from that of Stal or 
Dohrn, more importance being attached to the form of the thorax, as may be noticed 
from the characters used in the subjoined key of the genera. 
* Described by Mr. Ashmead as part of the mesonotum.
