This universal pest was observed by me in various places in Central America, but 
only a single specimen was preserved. It appears to tollow man everywhere in his 
wanderings. | 
HASMATOSIPHON, n. gen. 
Head very broad, short, sunk into the pronotum up to the eyes, the latter finely faceted and moderately 
prominent; rostrum extending to the middle of the posterior coxw, and received into a narrow groove 
between the coxe. Pronotum truncate at the base and apex, with the explanate margins narrow 
and of equal width throughout, the anterior angles very slightly produced forwards. LElytra not longer 
than the median portion of the first dorsal abdominal segment, separately rounded behind, and with 
the outer margins strongly reflexed. Abdomen in both sexes with the first dorsal suture straight, the 
following sutures, as well as all the ventral ones, becoming more and more sinuous posteriorly. Cox 
subcontiguous ; the intermediate pair separated by a thin lamella only, the posterior pair by a narrow 
prolongation of the raised intercoxal process of the abdomen, the latter widening posteriorly and extending 
as far as the apex of the fourth ventral segment. Tarsal claws very slender, simple. Genital segments 
of the male asymmetrically formed. Fourth ventral segment in the female unemarginate on the left side 
at the apex. The other characters as in Cimew. 
As the late A. Dugés anticipated, the insect described by him under the name 
Acanthia inodora cannot be retained in the same genus with Cimex lectularius, Linn. 
The very long rostrum, the deeply inserted head, the subcontiguous intermediate and 
hind coxe, the form of the pronotum, and also that of the abdomen, the laterally 
margined elytra, &c., separate it at once from C. lectwlarius and its allies. 
The single known species infests poultry, and it appears to be a troublesome pest 
wherever it occurs. Dugés states that H. inodora is without an odoriferous apparatus, 
but this is a mistake.

According to Prof. Townsend *, who describes the nymph, this insect is known in 
New Mexico by the name of “coruco.” He states that “‘ when the insect once gains 
access to a hen-house, it soon swarms in great numbers, infesting the inmates anil 
roosts, and covering the eggs with its excrementa, which show as black specks. It is 
a very difficult pest to exterminate, and has frequently been known to spread from 
roosts to dwelling-houses, where it proves more formidable than the bed-bug.”’ 
Dr. E. Dugés has been kind enough to send us specimens of both sexes of the species 
from Guanajuato.
