86 HEMIPTERA-HETEROPTERA. 
Hab. Guatemaa, Zapote (Champion); Costa Rica, Irazu (Rogers); Panama (Boucard). 
—Braziu? 545, Para!, Minas Geraés°, Rio Janeiro’. 
This species varies in the length and coloration of the pronotal spines, which are 
sometimes luteous or castaneous; and the upper surface of the body is also most variable 
in colour in different specimens. Of three specimens received from Central America 
there is a remarkable constancy in these respects, one of which, from Panama, is 
figured. 
2. Peromatus robustus. 
Peromatus robustus, Haglund, Stett. ent. Zeit. xxix. p. 161.11; Stal, En. Hem. u. p. 49. 3%. 
Hab. Mexico1?, Vera Cruz?. 
T have not seen this species. It seems closely allied to P. validus, Dall., a Brazilian 
form ; and, from Haglund’s description, it must be easily recognized from the preceding 
species by the obtuse spines of the pronotum not being constricted at the base and by 
the colour of the antenne, “articulo primo excepto, nigris.” 
8. Peromatus truncatus, n. sp. (Tab. X. fig. 1.) 
Ochreous, shining; head sparingly punctured, the lateral lobes transversely striated. Pronotum sparingly 
punctate aud rugulose ; anterior margin broadly smooth and impuuctate, behind which it is transversely 
and much more decidedly rugulose; pronotal angles produced into short, broad, flat, obtuse processes. 
Scutellum somewhat thickly punctate, and rugulose at base; corium purplish, opaque, very thickly and 
finely punctured, the nervures shining luteous ; membrane dark, shining, cupreous. Body beneath ochreous, 
a purplish patch at odoriferous aperture, on outer margin of which is a large shining luteous spot ; abdo- 
men with a submarginal row of pitchy spots situated on segmental incisures, a faint central longitudinal 
fascia, and posterior margin of sixth abdominal segment also pitchy; antenne ochreous, third joint very 
long, remainder wanting. 
Long. 21 millim., lat. pronot. ang. 13 millim. 
Hab. Mexico (Mus. Berol.). 
This small and distinct species is most closely allied to P. nodifer, West., but differs 
from that species by the broad, flat and truncated angles of the pronotum. The figure 
is from a specimen in the Berlin Museum kindly lent me by Prof. Peters.
