280 HEMIPTERA-HETEROPTERA. 
4, Castolus subinermis. (Tab. XVII. fig. 6, 9.) 
Repipta subinermis, Stal, Stett. ent. Zeit. 1862, p. 447( 2)’. 
Castolus (Spinda) subinermis, Stal, Enum. Hemipt. ii. p. 80’. 
Hab. Mexico (Mus. Holm.12; coll. Signoret}, in Mus. Vind. Ces.). 
We have not received a specimen of this species, our figure of which is taken from 
one of the types. It differs from C. plagiaticollis in having the lateral angles of the 
pronotum armed with a stout outwardly projecting tooth, the head longer, and the legs 
much stouter, the femora especially. ‘The expanded postero-lateral margins of the 
pronotum are continued beneath the lateral spines, so that the latter appear to be 
emarginate behind. 
5. Castolus rufomarginatus, n. sp. (Tab. XVII. fig. 7, 2.) 
Q. Elongate, rather robust, somewhat shining ; nigro-piceous or black, the head, a streak on each side behind 
excepted, and some spots on the anterior lobe of the pronotum, obscurely rufescent ; the posterior lobe of 
the pronotum at the sides and base, the scutellum in great part, the pleural margins, the connexivum, 
and the dorsal segments of the abdomen, except along the middle, sanguineous, the membrane smoky ; 
clothed above and beneath with very short grey decumbent pubescence and with scattered intermixed 
erect hairs, the legs thickly pilose. Head gradually narrowing behind, armed with a short conical 
tubercle on each side before the eyes, the latter large; antenne slender, joint 1 slightly longer than, and 2 
not half the length of, 3. Pronotum with the posterior lobe angularly dilated at the sides, rather broadly 
margined at the base laterally, the base truncate in the middle, the disc with two short anteriorly 
converging carine in front; the anterior lobe sulcate down the centre, the anterior angles obtuse 
and tuberculiform. Elytra extending beyond the abdomen. Legs rather stout, the anterior femora 
incrassate. 
Length 12-124, breadth 5-53 millim. 
Hab. Mexico, Omealca in Vera Cruz (VM. Trujillo); Guaremata, Chacoj in Vera Paz 
(Champion). 
Two specimens, the one from Vera Paz being immature and in a bad state of 
preservation. Allied to C. suéinermis, Stal, but very differently coloured, and with the 
lateral angles of the pronotum unemarginate behind. It is very like Repipta fuscipes 
in general appearance. In the Mexican example, which we figure, the venter is thickly 
cinereo-pubescent, with a series of transverse bare spaces along the sides. 
HIRANETIS. 
Miranetis, Spinola, Essai sur les Hémipt. p. 112 (1837) ; Stal, Ofv. Vet.-Ak. Férh, xxiii. p. 294 
(1866) ; Enum. Hemipt. ii. pp. 69, 82. 
A Tropical-American genus including three or four species. It is very closely allied 
to Graptocleptes. These insects greatly resemble various Ichneumonide and Braconide, 
and they are variable in colour. The head above and beneath is densely pilose, and 
the wings and elytra are banded with black; the third antennal joint is thickened 
in the males.
