80 HEMIPTERA-HETEROPTERA. 
unemarginate apical process and short, obtuse antenniferous processes, the post-ocular portions tumid and 
unarmed, the eyes rather large and not prominent; antennw stout, moderately long, joints 1 and 3 
subequal in length, 1 granulate, about three times as long as the apical process, 2 considerably shorter 
than 1, 2 and 3 more slender than 1 or 4, 4 fusiform, longer than 3. Pronotum greatly narrowed and 
declivous at the sides in front, widened and convex behind, about twice as wide at the base as at the 
apex ; the anterior portion very short, narrowing forwards, with two prominent flattened callosities on 
the disc ; the posterior portion rounded at the sides anteriorly and parallel behind, irregularly rugose and 
granulate. Scutellum transversely rugose, raised along the middle. Corium acute at the tip, with the 
apical margin obliquely truncate. Abdomen somewhat rounded at the sides, the margins crenulate; the 
sixth connexival segment obliquely narrowed in the male, abruptly narrowed in the female. Meso- and 
metasternum coarsely, transversely wrinkled at the sides, depressed in the centre. Venter finely rugulose, 
the segments 2-5 each with a narrow, smooth, posteriorly widened space in the centre, limited on each side 
by a pallid streak, the first segment with a deep transverse depression in the centre; the spiracles placed 
near the outer margin. Terminal genital segment of the male very broad and convex, transversely 
cordate, the genital lobes very short and inconspicuous. 
Length 5-64, breadth 2,1,-25 millim. (¢ ?.) 
Hab. Mexico, Teapa in Tabasco (H. H. Smith); Guatemata, San Juan in Vera Paz 
(Champion) ; Panama, Bugaba, Volcan de Chiriqui (Champton).—Amazons, Paré!. 
We possess eight examples of this species, five of which are from Chiriqui, these 
agreeing with the type in the British Museum, I had at first treated this insect as the 
type of a new genus, but Dr. Bergroth, who has made the Aradide his special study 
for many years, is of opinion that it cannot be separated from Aphleboderrhis. In some 
specimens the surface is partly covered by a pallid incrustation. A male from Teapa 
‘and a female from San Juan are figured. | 
PICTINUS. 
Pictinus, Stal, Enum. Hemipt. i. pp. 140, 145 (1873). 
Dr. Bergroth informs me that of the numerous species referred by him to Pictinus, 
four only (P. aurivillii, P. fronto, P. invalidus, and P. modigliani) really belong to it, 
P. hirticornis, P. procerulus, and P. tomentosus pertaining to Aphleboderrhis, and 
P. asiaticus and P. pusio to a new genus. One only was known to Stal, P. cinctipes, 
the type of the genus. The six Central-American species, all of which are treated as 
new, differ inter se in the form of the head, antenne, and pronotum, and to some 
extent in the position of the spiracles, these being sometimes placed on or so near the 
lateral margins of the abdomen as to be visible from above. The genus seems best 
placed here. The neuration of the membrane is obsolete or very indistinct, a character 
separating Pictinus from most of the allied forms. 
a. Head transverse. 
a’. Posterior portion of the pronotum unarmed at the sides; spiracles 
small, 
a', Anterior angles of the pronotum strongly, abruptly lobate; head 
with a long, acute, post-ocular spine.
