300 HEMIPTERA-HETEROPTERA. 
fab. Nort America, Kansas 2, Texas !2,—Panama, Caldera in Chiriqui ( Champion). 
One specimen. Very like P. fusca, but with the elytra less shining, the rostrum 
very elongate, the eyes larger and more coarsely faceted, the anterior femora differently 
‘formed. St&l’s type (2 ) of the macropterous form has been seen. 
ALLGZORHYNCHUS. 
Alleorhynchus, Fieber, Europ. Hemipt. pp. 48, 159 (1861); Stal, Hemipt. Afr. iii. p. 40; Enum. 
Hemipt. iii. pp. 107, 109. | 
A very widely distributed genus, two of the three described American species occurring 
within our limits. In these insects, as in the Palearctic A. flavipes, Fieb., the anterior 
femora are strongly incrassate and angularly dilated on the lower side a little before 
the middle, with the lower margin finely denticulate thence to the apex, the intermediate 
‘pair being similarly formed, but more slender; the anterior tibie are also abruptly 
dilated on the inner side at the apex, with a spongy fossa extending along the widened 
portion. 
1, Alleorhynchus vittativentris. (Tab. XVIII. fig. 19, 2.) 
Alleworhynchus vittativentris, Stal, Enum. Hemipt. ii. p. 109 ( 2) (1873). 
Hab. Panama, Volcan de Chiriqui 3000 feet (Champion).—CotomB1A, Bogota 1. 
One female example, agreeing with Stal’s type now before me*. 
A. armatus, Uhler, from the Island of Grenada, is a very closely allied form, but 
differs in having the anterior tibize widened for a shorter distance at the apex, and 
the elytra partly flavous. 
2. Alleorhynchus trimacula, (Tab. XVIII. fig. 20.) 
Prostemma trimacula, Stein, Berl. ent. Zeitschr. 1860, p. 76°. 
Alleorhynchus trimacula, Stal, Enum. Hemipt. iii. p. 109’. 
Hab. Muxico, Oaxaca 2 (Deppe, in Mus. Berol.1); Guatemata, Cahabon, Panima, 
San Gerdnimo, Las Mercedes, Zapote (Champion); Panama, Bugaba, Volcan de Chiriqui 
(Champion). 
We possess eleven specimens of this species, which is easily distinguishable by the 
trimaculate posterior lobe of the pronotum. An example from Bugaba is figured. 
PHORTICUS. 
Phorticus, Stal, Rio Jan. Hemipt. i. p. 69 (1860) ; Enum. Hemipt. iii. pp. 107, 109. 
Like Aliworhynchus, a widely distributed genus. Of the eight described species, two 
are American, one of them being now known to inhabit Eastern Mexico. In this 
* The scutellum in this specimen is injured by the pin and appears to be shining, instead of opaque, as in 
the Chiriqui example. _ ;
