pion).——SovutH America! 28, Colombia®, Venezuela ®, Cayenne ®, Pard®, Paraguay °. 
The four specimens seen from within our limits include both sexes, the male (as 
noted by Faust °) having the first ventral segment bituberculate at the apex. 
HAMMATOSTYLUS, nom. nov. 
Hammacerus, Chevrolat, Ann. Soc. Ent. Fr. 1879, p. 7 (nomen preocc.). 
The Tropical-American forms referred to this genus* have the rostrum slender, 
feebly curved, and as long as or longer than the body, with the scrobes oblique and 
evanescent behind, the antennal scape much thickened at the apex, the second joint 
of the funiculus and the first tarsal joint both very elongate (the former being nearly 
three times as long as the third joint, and the latter fully half the length of the tibia), 
the eyes well separated above, the scutellum small, and the prothorax plicate on each 
side at the base. In the single species now added the tarsal claws have a short tooth 
at the base. 
1. Hammatostylus criniger, sp.n. (Tab. XIV. figg. 6, ¢ ; 7,74, 2.) 
Elongate, shining, nigro-piceous or piceous, the outer half of the rostrum and the legs rufo-piceous; the 
elytral interstices 2 and 4 each with a scattered series of very long, erect, coarse, blunt, yellow sete, 
and 6 also with two similar sete before the middle. Head sparsely, very minutely punctate, shallowly 
foveate between the eyes, which are large, coarsely facetted, and somewhat distant above; rostrum 
slender, as long as or longer than the body in the 9, a little shorter in the d, finely punctate in its 
basal half, and almost smooth thence to the apex, the basal portion asperate beneath in the g, the scape 
not reaching the eyes, the scrobes descending and rather short; antenne inserted before the middle of 
the rostrum in the 2, and at the middle in the dg, slender, joint 2 of the funiculus elongate, twice as long 
as 3, the scape thickened at the tip. Prothorax much longer than broad, convex, rounded at the sides, 
constricted in front, smooth, except for some scattered punctures at the apex; the short basal portion 
transversely depressed, plicate at the sides, which are parallel as seen from above. Llytra elongate, a 
little wider than the prothorax, narrowing from about the basal third, constricted in front, the humeri 
obliquely truncated anteriorly ; very finely seriate-punctate, the punctures distant one from another, the 
setigerous impressions coarser. Under surface almost smooth. First ventral segment flattened along the 
middle, and the fifth depressed in the centre at the apex,in the ¢. Legs elongate; anterior femora 
distinctly, and the other pairs obsoletely, toothed ; tibiee simply sinuate ; first tarsal joint very elongate, 
especially that of the anterior pair in the @ ; tarsal claws with a short tooth at the base. 
Length 9-13, of the rostrum 74-14, breadth 23-3? millim. (d @.) 
Hab. Ntcaracua, Chontales (Belt, Janson); Costa Rica, San Carlos and Tucurrique 
(Mus. Dresden). 
Three specimens from each locality. This species is allied to Toxophorus brenthoides, 
Guér., Toxeutes gronovii, Schénh., and other Tropical-American forms included by 
* H. delauneyi, Chevr. (Bull. Soc. Ent. Fr. 1880, p. xxvi), from Guadeloupe, is probably a true Hrodiscus.
