HEMIPTERA-HETEROPTERA. 409 
Gonatas divergens (p. 219). | 
To the localities given, add :—Muxtco, Tierra Colorada in Guerrero, Teapa in 
Tabasco (H. H. Smith); Panama, Volcan de Chiriqui 2500 to 4000 feet, San Feliz, 
Tolé (Champion). 
DORACHOSA, gen. nov. (To follow the genus Gonatas, p. 220.) 
Allied to Gonatas, Dist., but differing by the much more concave basal margin to the pronotum; the very 
much longer scutellum ; the head, including eyes, not narrower than the anterior margin of pronotum ; 
the body more elongate and attenuated posteriorly. 
1. Dorachosa illuminatus, n. sp. (Tab. XXXVI. fig. 1.) 
Black ; basal joint of antenne (excluding apex) and the legs ochraceous; apices of the femora and the 
tibiz and the tarsi more or less infuscated. Antenne with the second joint considerably longer than the 
third, which is almost the length of the fourth ; margins of the anterior lobe and the whole basal lobe of 
the pronotum and the scutellum thickly and finely punctate; corium sparingly but coarsely punctate ; 
membrane pale fuscous. 
Long. 53 millim. 
Hab. Mexico, Omilteme in Guerrero 8000 feet (H. H. Smith); Guatemaa, Quiché 
Mts. 8000 feet (Champion). 
We have received one example from Mexico and three from Guatemala. 
Var. umbrosus (n. sp. ?). 
Body including legs and antenne wholly black. 
Long. 54 millim. 
Hab. Nortu America, Texas (coll. Dist.)—Muxico, Presidio de Mazatlan in Sinaloa 
(Forrer); GuaTEMALA, Ostuncalco, Quiché Mts. (Champion); Panama, Volcan de 
Chiriqui 4000 to 6000 feet (Champion). 
Beyond the colour, I can find no sufficient structural character to warrant this form 
being described as a distinct species. We have received it much more plentifully than 
the typical form here described. 
BUBACES, gen. nov. (To follow the genus Dorachosa.) 
Head longer than broad, inserted almost to the posterior margin of the eyes. Antenne with the first joint 
very long, and passing the apex of the head for half its length. Pronotum as long as broad, nearly 
twice as broad at base as at apex, constricted near centre, the lateral angles subprominent. Scutellum 
scarcely longer than the claval suture. Clavus thickly longitudinally punctate. Corium widened 
towards apex. Membrane complete. Rostrum with the first joint reaching basal margin of the head, 
the fourth joint considerably passing the posterior coxe. 
1. Bubaces castaneus, n. sp. (‘Tab. XXXVI. fig. 2.) 
Castaneous ; eyes black, lateral angles of the pronotum and lateral margins of the corium pale ochraceous ; 
antenne with the first and second joints ochraceous, the third pale fuscous (remainder mutilated); body 
beneath very dark castaneous; membrane with the lateral margins pale hyaline. Antennzy with the
