margins, apex, and basal spot black. Corium ochraceous, punctured with brown, the lateral margins 
impunctate, with an elongate spot near centre and at apex dark castaneous. Membrane fuscous, the 
veins at base ochraceous. Body beneath dark castaneous ; the legs ochraceous, femora and tarsi more or 
less castaneous ; antenns: ochraceous, the fourth and apical half of the third joint blackish. Antenne 
with the second and third joints subequal in length. 
Long. 4 millim. 
Hab. Guatemaa, Totonicapam (Champion); Panama, Volcan de Chiriqui 4000 feet 
(Champion). 
Allied to E. tropicus, Dist., but differing by the larger size, less globose anterior 
lobe of the pronotum, different colour of the antenne, &c. 
Two examples. 
BALBOA, gen. nov. (To follow the genus Hremocoris, p. 219.) 
General characters of Lethewus, Dall., but differing from that genus by having the second joint of the antenne 
not longest, but only subequal in length to the fourth; the rostrum has the basal joint as long as the 
head and not shorter than the second and third joints. Anterior femora spined beneath. Membrane 
with the second, third, and fourth nervures neither united nor forming basal cells. By the last 
character Balboa is allied to Cistalia, St&l, but differs by having the basal joint of the antenne 
somewhat thickened as in Letheus, as well as by the other characters enumerated above. 
1. Balboa variabilis, n. sp. (Tab. XXXV. fig. 25.) 
Ochraceous, somewhat thickly and coarsely punctured with brown; apex of third and apical half of fourth 
joint of antenne, head, anterior lobe of pronotum, a spot on each side of the clavus near apex, two 
spots on inner margin of corium, and two spots on its lateral margin—one near centre and the other at 
apex,—head beneath, and sternum black. The lateral margins of the corium are impunctate, the 
membrane much clouded with fuscous ; the legs are ochraceous, with the apices of the femora more or 
less annulated with castaneous. 
Var. a. Darker in hue and the posterior lobe of the pronotum with three longitudinal black fascize.

Long. 53-73 millim. 
Hab. Mexico, Orizaba in Vera Cruz (H. H. Smith & F. D. G.), Omilteme in 
Guerrero (H. H. Smith); Guatemata, Quezaltenango, Quiché Mts., Cerro Zunil, 
Volcan de Atitlan, Chiacam, San Gerénimo, Coban (Champion); Panama, Volcan 
de Chiriqui 2000 to 6000 feet (Champion). 
Of this very variable species, both in size and colour, we have received a long series ; 
it appears to be scarce in Mexico and very plentiful in Guatemala. In some of the 
typical forms the anterior lobe of the pronotum is castaneous rather than black.

To the localities given, add :—Mzxico, Omilteme in Guerrero (H. H. Smith); Guate-
