168 HEMIPTERA-HETEROTERA. 
Besides its different colour and markings, the much less rounded and produced 
lateral angles of the pronotum will separate this species from H. subrufus. 
B. Basal joint of the antenne scarcely or slightly passing the apex of the head.

Hab. Nortu America, Indiana 1, Georgia ! 3, Maryland 3, Texas ? 3,—-Mexico, Orizaba, 
Cuernavaca (Bilimek, Mus. Vind. Ces.) ; GuatEMALA, Duefias, Cerro Zunil (Champion). 
The Central-American specimens appear to agree well with Say’s description. 
B. Abdomen dilated on each side. 
7. Harmostes propinquus, n.sp. (Tab. XV. fig. 19.) 
Head and pronotum dull ochraceous, with some scattered and irregular fuscous shadings, obscurely punctate. 
Antenne ochraceous, basal joint scarcely passing apex of head, second joint shorter.than third, and about 
equal to fourth, which is fuscous, with the base ochraceous. Pronotum with the anterior lateral margins 
obscurely crenulated, the lateral angles subprominent and rounded, the anterior angles prominent and 
acute. Scutellum ochraceous, distinctly punctate. Corium dark greyish, with the nervures and costal 
margin ochraceous. Membrane pale hyaline. Connexivum dull ochraceous, with luteous spots. Under- 
side of body and legs ochraceous ; sternum and abdomen sometimes with some obscure fuscous longitudinal 
streaks. Underside of apices of posterior femora fuscous, and with a row of strong spines. Abdomen 
dilated and projecting beyond the corium on each side. 
Long. 6 to 7 millim, 
Hab. Mexico, Tacubaya (Bilimek, Mus. Vind. Cces.); Guatemata, Santa Rosa 
(Champion). 
The dilated abdomen separates this very distinct species. 
8. Harmostes dorsalis. 
Harmostes dorsalis, Burm. Handb. i. 1, p. 307°; Stal, En. Hem. i. p. 221. 11. 
Hab. Mexico 1. 
I have with Stal been unable to identify this species; it probably represents one of the 
preceding Mexican species ; but the description is too slight for any accurate decision. 
AUFEIUS. 
Aufeius, Stal, En. Hem. i, p. 221 (1870). 
This genus at present contains but one species; and the characters relied upon by 
Stal for separating it from Harmostes are, “thorace disco impresso, carina media 
destituto, abdomine hemelytris latiore divergit.”
