RHYNCHOPHORA : OTIORHYNCHIN &. 337 
and acuminate-ovate in shape. Ihave seen three other females, from Mexico, agreeing 
exactly with the one from San Antonio; the male will doubtless prove to be nearly 
related to that of P. elegans. The last-mentioned insect is said to live on cotton 
( Gossypium). 
29 (s). Pantomorus trituberculatus, sp. n. 
Oblong, narrow (3), broader (2), black; thickly clothed with greyish-brown scales, the prothorax with 
indications of two faint vitte on the dise and a stripe on each flank, and the elytra with the sides, base, 
and in one specimen several faint oblique or oblong streaks on the disc, indeterminately whitish or 
cinereous, the intermixed scattered sete very short and inconspicuous. Rostrum flattened above, the 
narrow median sulcus extending upwards to the feeble, transverse, post-ocular depression of the head ; 
eyes very prominent ; antenne Jong and slender, joint 2 of the funicnlus elongate, much longer than 1. 
Prothorax convex, transverse, relatively narrower and longer in ¢, rounded at the sides, subtruncate at 
the base, densely, finely punctate and canaliculate. Elytra a little broader than the prothorax in 6, 
wider in 2, suboval, truncate at the base, the humeri distinct; punctate-striate. Tibiw# and tarsi 
comparatively slender; anterior tibie closely denticulate ; posterior tibixe feebly lamellate at the tip. 
3. Intermediate tibie strongly unguiculate ; second ventral segment armed with three, transversely placed, 
small black tubercles. 
Length 53-84, breadth 2-3 millim. (¢ 92.) 
Hab. Mexico, Tehuantepec in Oaxaca (Anab, in U.S. Nat. Aus.). 
Three males and two females, all somewhat worn, one of each sex retained for the 
British Museum. A small narrow form (at least in male), with comparatively slender 
tibiz and tarsi, the prothorax and elytra subtruncate at the base, the second ventral 
segment trituberculate in the male, &c. 
Pantomorus femoratus (p. 165). 
To the localities given, add :—Nicaragua, San Marcos and Chinandega (Baker) ; 
Costa Rica, Guanacaste (Pittier), Escazu (Biolley), Atenas, Piedras Negras, Las Loras 
near Puntarenas (U.S. Nat. Mus.). 
The type (¢) of this species is immature. We have nowreceived a long series of it 
from Costa Rica. They have the vestiture uniformly whitish or cinereous, often with a 
greenish, cupreous, or brownish tinge. The male has the second ventral segment unarmed 
and the first segment hollowed down the middle. The under surface is thickly clothed 
with long erect white hairs. The hind tibiew have an oval squamose space at the tip. 
Pantomorus robustus (p. 166). 
Two abraded females from Momotombo, Nicaragua, sent us by Mr. Wickham, may 
belong to this species. It is not at all improbable that P. robustus, described from two 
females from Chontales*, is the sexual complement of P. strabo, described from a 
single male from the same locality, the great difference in size and in the colour of 
the scales notwithstanding, P. globicollis varying in a similar way. The eyes are feebly 
convex in both P. strabo and P. robustus, but less depressed than in P. sulfureus. 
* There is also another female of it from Nicaragua in Signor A. Solari’s collection.
