STHENAROPS. (To follow the genus Calocoris, p. 267.) 
Sthenarops, Uhler, Bull. U.S. Geol. & Geogr. Surv. ili. p. 418 (1877). 
Sthenarops is closely allied to Calocoris, and includes a species I formerly placed 
with doubt in that genus. 
1. Sthenarops malina. 
Sthenarops malina, Uhler, Bull. U.S. Geol. & Geogr. Surv. iii. p. 419. 2°. 
Calocoris (?) inustus, huj. op. p. 267, Tab. XXIII. fig. 17°. 
Calocoris inustus, Uhler, Check-List Hem. Het. p. 18, 870 (1886). 
To the locality previously given?, add:—Norta America, Eastern Massachusetts, 
New York, Pennsylvania, Maryland, Ohio, Southern Illinois, Texas !.—Mzexico, Chilpan- 
cingo and Tepetlapa in Guerrero (H. H. Smith). 
There is scarcely a doubt that the Mexican Capsid I described as above ? is the widely- 
distributed North-American species described by Prof. Uhler, though that author has 
included my species under the genus Calocoris in his Check-List. It seems that both 
Prof. Uhler and myself have committed an oversight. 
MEGACCELUM (p. 269). 
2. Megacelum (?) sanguinolentum, n. sp. (Tab. XX XVII. fig. 13.) 
Very pale ochraceous; scutellum with two black spots near the apex, which is sanguineous; head with a 
rounded linear sanguineous spot in front of the eyes; pronotum and corium much suffused with 
sanguineous, the first with a narrow subbasal broken linear dark sanguineous fascia; membrane pale 
fuscous; body beneath and legs pale ochraceous ; apex of the rostrum fuscous (imperfectly seen in carded 
specimens). 
Long. 8 millim. 
Hab. Mzxico, Pinos Altos in Chihuahua (Buchan-Hepburn). 
We have received two specimens of this species, which I place in the genus Mega- 
celum principally on account of the structure of the apex of the scutellum, which is 
deflexed and curved downwardly. It is allied to the other species here described, 
M. (2) signatum, Dist., by the spots to the scutellum, but differs by the more parallel 
lateral margins of the corium, the sanguineous shadings, the colour of the membrane, &c. 
PROBA (p. 269). 
Proba gracilis (p. 269). 
To the localities given, add :—MeExico, Omilteme in Guerrero (H. H. Smith); Guats- 
MALA, San Geronimo (Champion). 
In its melanic forms, this species is a close mimic of Lygus tribulis, Dist. 
PARAPROBA (p. 270). 
Paraproba fasciata (p. 270). 
To the localities given, add :—Mzexico, Orizaba in Vera Cruz (H. H. Smith & F. D. G.),
