216 HEMIPTERA-HETEROPTERA. 
1. Rhyparochromus plenus, n. sp. (Tab. XIX. fig. 23.) 
Head and pronotum bronzy black, the last coarsely punctate, but more prominently so on the posterior lobe ; 
seutellum bronzy black, and, excluding a central carinate line, very coarsely punctate. Corium dull 
ochraceous, the clavus much suffused with pale piceous, a pale piceous subcostal fascia (ill-defined) not 
reaching base and terminating about centre, where it amalgamates with a large bright black patch, which 
occupies apical half of corium. Membrane pale hyaline, very much abbreviated, and not reaching apex 
of abdomen. Antenne pilose, pale piceous, basal joint, excepting apex, and basal portion of second joint 
much darker ; second joint subequal or a little longer than fourth; the third joint longer than first, but 
shorter than second or fourth. Body beneath bronzy black, lateral margins of meso- and metasternum 
ochraceous ; legs black ; apices of femora, apical portions of tibia, and tarsi dark ochraceous. 
Long. 3 millim. 
Hab. Guatemaa, Quezaltenango (Champion). 
The very different markings and coloration will alone distinguish this species from 
. una, the only other recorded American representative of the genus. 
TRAPEZONOTUS. 
Trapezonotus, Fieber, Eur. Hem. pp. 50 & 190 (1861); Stal, Ofv. Vet.-Ak. Férh. 29: 7, p. 55 
(1872); En. Hem. iv. p. 158 (1874). 
In this genus the principal characters to be relied on, especially with reference to 
allied American genera, are the shape of the head and pronotum, both of which are 
transversely broad and not longer than broad. The basal joint of the antenne also 
only just passes the apex of the head. | 
This is another Palearctic genus, being well represented in Europe, where ten species 
are enumerated by Dr. Puton. One of these is also recorded by both Mr. Uhler and the 
late Dr. Stal as found in North America; and a second American species has been 
described from Texas. Neither of these has yet been received from Central America, 
from which, however, I am able to describe the following new species :— 
1. Trapezonotus caliginosus, n. sp. (Tab. XX. fig. 3.) 
Head black, pilose. Pronotum with the anterior lobe black, subrugulose, and finely punctate, the posterior 
lobe ochraceous, coarsely and, in some places, confluently punctured with black ; the margins ochraceous 
and impunctate. Scutellum piceous, very finely and sparingly punctate, the apical margins more distinctly 
and coarsely punctate. Corium ochraceous, coarsely and, in some places, confluently punctured with 
black; the lateral margins impunctate. Membrane pale fuscous, the margins and veins ochraceous. 
Antenne pale brown, the apical joint darkest ; first, second, and third joints pilose; second joint longest, 
fourth joint a little longer than third. Body beneath piceous, lateral margins of sternum and acetabula _ 
ochraceous; legs variable in coloration, in some specimens almost uniformly ochraceous, in others with 
the anterior femora (excepting apices) and broad apical annulations to intermediate and posterior femora 
more or less castaneous. 
Long. 4 to 5 millim. 
Hab. GuatEMaLa, Quezaltenango, Quiche Mountains (Champion) ; Panama, Volcan de 
Chiriqui, 4000-6000 feet (Champion). 
In this genus considerable allowance must be made for the amount of ampliation of
