148 HEMIPTERA-HETEROPTERA. 
COLLATIA. 
 Collatia, Stal, Stett. ent. Zeit. xxiii. p. 298 (1862); Ofv. Vet.-Ak. Férh. 1867, p. 547. 
Collatia differs from Zicca in having the basal joint of the antenne shorter than the 
second. The pronotal angles are ampliated and sinuated. 
Three species of this genus are now described, all of which are from Central America, 
1. Collatia emarginata. (Tab. XIV. fig. 14.) 
Collatia emarginata, Stal, Stett. ent. Zeit. xxiii. p. 298. 163*; En. Hem. i. p. 199. 17. 
Hab. Mexico'?; Guatema.a, Capetillo, Cubilguitz (Champion). 
The figure is from a typical Mexican specimen in the collection of the Stockholm 
Museum. 
2. Collatia jubata, n. sp. (Tab. XIV. fig. 15.) 
Collatia emarginata, Stal, var. ? 
Closely allied to C’. emarginata, Stal, but differs by the more elongate body and the greater elevation of the 
central longitudinal ridge to pronotum. The apex of the scutellum is not pale luteous, but apparently 
eoncolorous. 
Long. 9 millim. 
_ Hab. Muxico, Orizaba (Bilimek, Mus. Vind. Ces.). 
I have described this species from a single specimen in the Vienna Museum with 
considerable hesitation, as, though the structural differences between it and C. emargi- 
nata are considerable, as the artist has fully shown in the two figures, I have observed a 
tendency in Guatemalan specimens to vary in this particular, and shall not be surprised 
if eventually it prove to be but a varietal form. In the absence of intermediate forms, 
I have been compelled to separate it. 
3. Collatia divergens, n. sp. (Tab. XIV. fig. 17.) 
Above luteous, more or less covered with brownish punctures. Antenne with the first joint pale luteous, 
second and third joints somewhat darker, particularly at apices; apical joint testaceous; first and third 
joints subequal in length, second longest. Head obscurely punctate, with the central lobe somewhat raised 
and prominent. Pronotum somewhat thickly covered with brownish punctures ; lateral margins (which 
are strongly spinous) and a raised central longitudinal ridge on anterior portion of disk pale luteous ; 
lateral angles produced, their apices terminating in acute spines, which are slightly directed upwards and 
forwards, deeply sinuated behind. Scutellum with the basal half sparsely punctate, from which it is 
densely and darkly punctate to the apex, which is pale and levigate. Corium somewhat thickly covered 
with brown punctures, excepting about middle, where it is obscurely levigate, almost indicating a pale 
transverse fascia. Connexivum pale luteous, with a series of large subquadrate brown spots, which are 
spotted with fuscous on margin. Underside of body pale luteous, with two small transverse streaks 
between posterior coxe, two small rounded spots on disk of second segment, two transverse oblong spots 
on disk and basal margin of third segment, a small round spot on sides of fourth and fifth segments, 
and abdominal margin with a row of obscure spots, fuscous. Legs luteous; apices of femora pale testa- 
ceous ; cox and bases of femora with a few fuscous spots; tibie spotted with testaceous; rostrum about 
reaching posterior coxe, with the apex pitchy. 
Long. 9 millim.
