70 HEMIPTERA-HETEROPTERA. 
filiform, nearly twice as long as 2, 4 a little longer than 2, pilose at the tip. Pronotum transversely 
subquadrate, sinuate at the sides; the anterior lobe obliquely truncate on each side in front, concave 
externally, and truncate on each side at the base, with the angles prominent, the incrustation moulded 
into an inflated anteriorly bilobed prominence on the middle of the disc ; the posterior lobe with a feebly 
raised transverse bisinuate ridge on the disc, and a laterally projecting raised margin along the outer 
part of the base. Scutellum with an oblong more or less inflated prominence in the centre, connected in 
front with the raised basal margin, and with the sides also margined. Abdomen moderately long; the 
connexivum almost evenly rounded externally, the sixth segment with the outer apical angles obtuse or 
subangular ; the genital lobes stout. 
Length 33-4, breadth 13-2 millim. (¢ 9.) 
Hab. Panama, Bugaba, Volcan de Chiriqui, David, San Miguel in the Pearl Islands 
(Champion). 
Var.? The anterior lobe of the pronotum more dilated behind, with both angles very prominent, the posterior 
lobe without a transverse sinuous ridge on the disc; the segments 2-5 of the connexivum feebly arcuately 
dilated at the sides towards the apex. 
Length 5, breadth 23 millim. (@.) 
Hab. GuaTEMALA, Balheu in Vera Paz (Champion). 
Sixteen specimens of the typical form and one of the variety; the latter may prove 
to belong to a distinct species. Recognizable by the more or less inflated prominence on 
the middle of the scutellum and the bilobed prominence on the disc of the anterior 
lobe of the pronotum. In the specimen from Bugaba ( @ ) (fig. 6), the outer apical 
angles of the sixth connexival segment are subangular, instead of obtuse, as in all the 
other examples obtained, including both sexes. 
8. Proxius gypsatus. (Tab. V. figg. 8, ¢; 8a, antenna; 9, ¢, var.) 
Proxius gypsatus, Bergr. Ent. Monthly Mag. xxxiv. p. +e, 
Fusco-ferruginous, in great part covered by a thick whitish or whitish-ochreous incrustation ; the legs and 
antennee ferruginous, the membrane fuscous. Head with the post-ocular portions broadly, subangularly 
or acutely dilated to far beyond the eyes; the antenniferous processes spiniform and slightly divergent ; 
the apical lobes short; the callosities forming a raised elongate-triangular plate on the middle of the 
head, outside which is a groove for the reception of the antennez ; antenne short, joint I stout, reaching 
the apex of the apical lobes of the head, 2 ovate, a little shorter than 1, 3 slender, filiform, about one- 
half longer than 2, 4 not longer than 3, pilose at the tip. Pronotum transversely subquadrate, sinuate 
at the sides; the anterior lobe obliquely truncate on each side in front, hollowed externally, and truncate 
on each side at the base, the anterior angles usually more prominent than the posterior ones, the incrus- 
tation moulded into an inflated anteriorly bifurcate prominence on the middle of the disc; the posterior 
lobe with one or two transverse or oblique oval elevations on each side of the middle of the disc, a short 
feeble transverse ridge between them, and a curved laterally projecting ridge along the outer part of the 
anterior and posterior margins. Scutellum with a basal ridge, extending down the middle to the apex 
(forming a T-shaped prominence), the sides also margined. Abdomen moderately long; the connexivum 
almost evenly rounded externally, the sixth segment angularly projecting at the outer apical angles in 
both sexes ; the genital lobes slender in the male, stouter in the female. 
Length 34-44, breadth 1j-1? millim. (¢ @.)
