46 RHYNCHOPHORA. 
in form more like those of a Clavicorn than of a Rhynchophorous insect, the first and 
second joints being short and broad, the third bilobed, the fourth joint small but quite 
visible between the lobes of the third joint; the terminal joint large, with rather 
large claws; each of the joints 1—3 is furnished on either side with rather long: hairs, 
which project laterally as well as downwards. Hind femora very broad, their upper 
margin strongly arcuate, crenulate. | 
I am compelled to establish a new subfamily for the abnormal weevil from which 
the above characters are taken, the best place for which is near Rhynchitine, although 
no affinity is exhibited with any particular genus of that subfamily, and it differs 
strongly from the aberrant forms of Rhynchitine by the minute palpi and trophi. 
In appearance this singular insect is not at all similar to any other Curculionide 
known to me, though it has several characters of the Oxycorynides of Lacordaire, 
from which it differs by the unmargined sides of the pronotum, by the largely developed 
basal joint of the tarsi, and the exposed pygidium. 
ALLOCORYNUS, gen. nov. 
Antenne rect, basales. Rostrum gracile, cylindricum. Coxe anteriores contigue, subglobose, parum exserte. 
Tarsi dilatati, subtus longius hirtelli. Pygidium ab elytris haud obtectum. Oris partes minut, mandi- 
bule extus rotundate. 
1. Allocorynus mollis, sp.n. (Tab. II. fig. 18, 3.) 
Testaceus, antennis pedibusque flavo-testaceis, subdepressus, parce subtiliterque punctatus, subopacus ; rostro | 
cylindrico, subcurvato. 
Long. cum rostro 34-4 millim. 
Hab. Mexico, Ventanas in Durango, Tapachula in Chiapas (Hége). 
Rostrum of the male slightly longer than the thorax, punctulate, not shining; of the 
female as long as the head and thorax, more slender, impunctate, shining. Eyes coarsely 
granulate, large, and prominent; the space between them somewhat coarsely punctate. 
Antenne rather longer and more slender in the female than in the male; second joint 
shorter than the first ; terminal three joints forming a large, very loosely articulated club, 
the first joint of which is the largest, the apical joint being much smaller, acuminate, 
without any trace of division or constriction. ‘Thorax strongly transverse, rounded at 
the sides and narrowed in front, finely and rather sparingly punctate. Scutellum sub- 
quadrate. Llytra elongate, but leaving the terminal segment quite exposed, punctured 
like the thorax ; the apices separately rounded. 
Herr Hoge procured a small series of this obscure, unattractive, but interesting little 
insect. Unfortunately nearly all of them are so immature as to be nearly valueless.
