NICENTRUS. 315° 
towards the tip, the antenne inserted beyond the middle, the antennal club ovate. Prothorax transverse, 
rounded at the sides, constricted in front, feebly sinuate at the base; densely, finely punctate, except 
along a narrow smooth median space. Scutellum rounded, rather large. Elytra moderately long, sub- 
parallel in their basal half, flattened on the disc; finely punctate-striate, the interstices flat and closely 
punctate. Beneath densely punctate. Prosternum deeply sulcate. Anterior coxe narrowly separated. 
Length 3, breadth 15), millim. (@.) 
Hab. GuateMaLa, Chiacam in Vera Paz (Champion). 
One specimen, in perfect condition. It is possible that this insect may be a variety 
of NV. candidulus, but the white scales on the elytra in the present species are broad 
and imbricate, and condensed into spots. 
7. Nicentrus fulvipes, sp. n. 
Elongate-ovate, narrow, flattened above, black, the antenne and legs ferruginous; thickly clothed with rather 
coarse, narrow, brownish-white, adpressed scales, which are clustered into about two rows down each 
elytral interstice ; the vestiture of the under surface close and whitish. Head densely punctate; rostrum 
arcuate, moderately stout, short, about as long as the prothorax, sparsely, finely punctate, the antennx 
inserted at the middle, the antennal club ovate and rather small. Prothorax a little broader than long, 
somewhat rounded at the sides; densely, finely punctate. Scutellum rounded, squamose. Elytra very 
little wider than the prothorax, oblong, subparallel in their basal third; finely punctate-striate, the 
interstices rugulose. Beneath densely punctate. Prosternum deeply sulcate, the sulcus bordered on each 
side by a sharp ridge. Legs rather short; tibie strongly unguiculate. 
Length 22, breadth 1 millim. (92?) 
Hab. Panama, Volcan de Chiriqui 4000 feet (Champion). 
One specimen, somewhat abraded. The close, uniform, brownish-white vestiture of 
the upper surface, the squamose scutellum, the entirely ferruginous antenne and legs, 
and the short rostrum distinguish JV. fulvipes from its immediate allies. It is longer, 
less attenuate, and more densely squamose than JV. femoralis, the knees are 
unarmed, and the femora are sulcate at the apex only beneath. 
8. Nicentrus puerilis, sp. n. 
Oblong-ovate, narrow, shining, black, the tibie sometimes ferruginous ; above sparsely clothed with narrow 
whitish scales, which are condensed into a stripe along the sides of the prothorax and a spot in the middle 
at the base, the scales on the elytra arranged in a single line down each interstice ; the vestiture of the 
under surface closer and also whitish. Head closely punctate ; rostrum curved, rather slender, barely as 
long as the prothorax, rugulosely punctate in the g, shining and almost smooth in the 9, the antenne 
inserted at about the middle. Prothorax nearly as long as broad, rounded at the sides anteriorly, 
strongly constricted in front ; closely, rather coarsely punctate, except along the smooth median line. 
Scutellum small, squamose. lytra a little wider than the prothorax, transversely depressed below the 
base, the humeri somewhat swollen; sharply punctate-striate, the interstices uniseriate-punctate. 
Beneath closely punctate. Prosternum broad and shallowly sulcate, the groove limited on each side by a 
distinct ridge. First ventral segment deeply sulcate in the g. Anterior coxe narrowly separated. 
Legs rather long and slender ; tibie strongly unguiculate. 
Length 23-8, breadth 1-1,5 millim. (¢ 9.) 
Hab. Guatemata, Chiacam in Alta Vera Paz (Champion). 
Six specimens, all more or less abraded. Not unlike WV. lineicollis, Boh., but. 
smaller and narrower, the elytra subparallel at the base, the rostrum not so stout, the
