NEOMASTIX. 
Neomastix, Dietz, Trans. Am. Ent. Soc. xviii. p. 254 (1891). 
The two species here referred to this genus, hitherto including two minute forms 
from the Southern United States, possess the principal characters assigned to it by 
Dietz, viz. a 5-jointed funiculus and an ovate antennal club. In one of them (WN. setulosus) 
the tibie are unarmed at the apex, and in the other (WV. concolor) the femora are feebly 
unidentate. 
1. Neomastix concolor, sp. n. (Tab. XI. figg. 19, 194, 2, 3.) 
Subovate, shining, rufo-testaceous, the eyes black; sparsely clothed with rather long yellowish pubescence, 
which is subserially arranged on the elytra. Head rugulose, the eyes large, but not prominent, somewhat 
narrowly separated; rostrum rather stout, feebly curved, of the same length as the prothorax, dull and 
rugulose, shining at the tip, the scrobes descending to the lower edge of the eyes; antenne inserted before 
the middle of the rostrum, joint 1 of the funiculus stout, 2-5 small, 2 and 3 subequal in length, 4 and 5 
shorter and transverse, the club large and ovate. Prothorax short, subconical, constricted before the apex, 
densely, rugulosely punctate. LElytra much wider than the prothorax, convex, subparallel before the 
middle, the humeri a little swollen; coarsely and deeply punctate-striate, the interstices convex, each 
with a row of minute punctures. Legs slender; femora moderately clavate, each with a minute tooth; 
anterior and intermediate tibi sinuate within, and unguiculate at the apex, the hind tibie straighter 
and unarmed ; tarsal claws with a long tooth. 
Length 14, breadth 1 millim. (<¢.-) 
Hab. Guatemata, Duefias (Champion). 
One specimen. Not unlike some of the European species of the genus Nanophyes 
(which also have a 5-jointed funiculus), but easily separable therefrom by the toothed 
claws, the well-developed scutellum, &c. 
2. Neomastix setulosus, sp.n. (Tab. XI. figg. 20, 20a, 2.) 
Subovate, piceous, the legs in great part ferruginous ; thickly clothed with white pubescence, with intermixed, 
curled, erect, squamiform, white sete, which are coarse and prominent on the elytra, and arranged in a 
single series on each interstice; the legs with curled squamiform hairs. Rostrum rather slender, feebly 
curved, about as long as the head and prothorax, slightly widened at the tip, rugulose, the scrobes lateral, 
descending to the lower edge of the eyes, the antenne inserted at the middle, joint 1 of the funiculus 
stout, 2-5 small, the club ovate and moderately large; eyes very prominent, narrowly separated. 
Prothorax convex, transverse, feebly rounded at the sides, narrowing from a little before the base, 
slightly constricted before the middle, densely punctate. Elytra short, convex, considerably wider than 
the prothorax, subparallel towards the base, the humeri not prominent; deeply punctate-striate, the 
interstices very narrow and convex. Legs short and comparatively slender, the femora feebly clavate 
and unarmed, the tibie straight on their inner edge and without claw at the apex ; the tarsal claws with 
a short tooth. 
Length 1, breadth 3 millim. (g.) 
Hab. Nicaragua, Chontales (Janson). 
Three specimens, probably all females. This is the smallest Curculionid we have 
received from Central America. It is very like a minute Apion. The white sete on 
the elytra are looped, tapering at the end.
