RHYNCHOPHORA. 720 
Cholus cinctus (p. 299). 
To the localities given, add:—Cosra Rica, Azahar de Cartago, Carrillo (Underwood). 
18 (a). Cholus pittieri, sp.n. (Tab. XXXV. figg. 26, 264, 3.) 
Elongate-rhomboidal, flattened above, black ; the head, prothorax, and elytra with a continuous, depressed, 
submarginal vitta densely clothed with whitish scales, the under surface with three very broad whitish 
stripes, the central one reaching the apex of the first ventral segment, the legs clothed with a few narrow 
whitish scales. Head finely punctate, the eyes very large; rostrum moderately stout, curved, about as 
long as the prothorax, carinate and rugulosely punctate at the base, becoming much smoother towards the 
apex, the antenne inserted beyond the middle. Prothorax broader than long, rounded at the sides 
posteriorly and rapidly narrowing forwards, the base very deeply bisinuate; the surface granulate. 
Scutellum longer than broad. Hlytra elongate-cordate, not wider than the prothorax ; seriato-granulate 
and indistinctly seriate-punctate on the disc, the punctures deep, transverse, and regularly arranged at 
the sides. Mesosternum flattened between the coxw. First ventral segment broadly flattened down the 
middle. Legs elongate, the femora each with a long narrow tooth. 
Length 173, breadth 74 millim. ( 3.) 
Hab. Costa Rica, Zeut, Atlantic slope, 20 metres (Pittier). 
One specimen. More elongate than C. circumnotatus and C. cinctus, and much 
narrower than the latter; the prothorax arcuately dilated at the sides posteriorly and 
deeply bisinuate at the base, the under surface with three very broad, dense, whitish 
stripes, the metasternum and ventral segments without bare spots or granules at the 
sides, the outer portion of the elytra with regular rows of transverse punctures. The 
whitish scales cover the whole of the under surface, with the exception of the smooth 
space along the middle of the abdomen, which is continued forwards on each side 
in a line with the coxe. The spaces between the granules of the upper surface are 
coated with a brownish exudation. Cholus jocosus, Heller, from Colombia, is a near 
ally of C. pittiert. 
20 (a). Cholus bipertitus (p. 300). (Tab. XXXV. fig. 27, 3.) 
Cholus bipertitus, Heller, Stett. ent. Zeit. 1906, p. 21°. 
Hab. Cosra Rica, San Carlos (Mus. Dresden"), Carrillo, Azahar de Cartago (Underwood). 
This insect is a form of C. inwqualis *, from Chiriqui, from which it differs in having 
a transverse white line, or a row of small white spots, on the elytra at about one-third 
from the base, and the elytra themselves broadly flattened thence to the apex. We 
have received three specimens of it (including ¢ and @), agreeing with the type 
communicated by Dr. Heller. 
Cholus foveolatus (p. 301). 
To the Costa Rican localities given, add :—Escazu (Underwood). 
Another specimen of this species is now to hand, differing from the two described in 
having the squamigerous depressions on the prothorax and elytra larger and more 
irregular, the seriate punctures on the latter visible between them. 
* In the general remarks on C. inequalis (antea, p. 300) for “ mesonotum ” read “ mesosternum.”
