16 HEMIPTERA-HETEROPTERA. 
BENEATH LUTEOUS WITH GREEN REFLEXIONS. 
Var. 7. (Tab. I. fig. 7.) 
Pronotum and scutellum greenish, irregularly marked with reddish spots, which are sometimes confluent. Head 
reddish, with two central greenish lines. 
This is an extreme varietal form, and ‘seems to come close to the var. ¢ of Stal, En. 
Hem. i. p. 6 (1870). 
This species is distinguished from P. fadricii, Linn., and the following species by the 
shape of the head (which has the lateral margins considerably sinuated), and by the 
distinct punctuation of the surface of the same. 
Hab. Catirornia (Uhler).—Mexico (var. d), Oaxaca (vars. a, ¢, d); Nicaragua, 
Chontales (vars. a, 7); Costa Rica (v. Patten) (vars. a, 6, d, e, f, g, h), Caché (Rogers) 
(var. a), Irazu (Rogers) (var. e); GuateMALA, San Juan (var. ¢), San Gerdnimo (Cham- 
pion) (var. @).—CoLoMBIa (var. c); BRazi (var. a). 
2. Pachycoris dissociatus. 
Pachycoris dissociatus, Uhler, Proc. Ent. Soc. Philad. i. p. 21°. 
Hab. Muxico, Nuevo Leon!; Costa Rica (Coll. Dist.). 
A specimen from Costa Rica seems to agree with Prof. Uhler’s description, and would 
appear to be only an extreme melanic variety of P. torridus. Our own specimen is 
separated from that species by the much more deeply sinuated lateral margins of the 
head. I have unfortunately been only able to examine one specimen, the antenne of 
which are absent. 
ASCANIUS. 
Ascanius, Stil, Ofv. Vet.-Ak. Forh. 1867, p. 492. 
This genus is best recognized by the more or less erosion of the abdominal margins, and 
the hexagonal pronotum, of which the anterior is longer than the antero-lateral margins. 
Two species are recorded, both from the Amazonian subregion, one of which we now 
include in this fauna. Z 
1. Ascanius atomarius. 
Pachycoris atomarius, Germ. Zeitschr. i. p. 96. 80 ; H.-S. Wanz. Ins. v. p. 10. f. 4687, 
Hab. Mexico (Mus. Berol.).—BRaziu 4. 
. Two specimens of this species from Mexico are in the collection of the Berlin 
Museum. 
ORSILOCHUS. 
Orsilochus, Stal, Ofv. Vet.-Ak. Férh. 1867, p. 493. 
Of the five species at present known as constituting the genus, three are found in 
Central America, one, O guttatus, H.-S., is a Nearctic form, and the other, 0. leuco- 
pterus, Germ., has only been recorded from Brazil.
