DENDROTERUS. 233 
DENDROTERUS, gen. nov. 
Funiculus antennarum perbrevis, 4-articulatus, articulis 2-4 transversis; clava sat magna, breviter ovalis, 
compressa, 3-articulata, suturis transversis, piliferis. Tibia anguste, supra dentibus 2 armate, ad apicem 
oblique truncate ; tarsi breves, articulis 1-3 equalibus. 
Head defiexed, not subrostrate. Antennal scape short, curved, little thickened apically ; funiculus very short, 
4-jointed, the first joint cupulate, the second conical, the third and fourth transverse, successively wider ; 
club short-oval, flattened, shining, 3-jointed, the joints successively shorter, sutures transverse, fringed. 
Prothorax longer than broad, without basal margin, its anterior ventral border not reaching the closely 
approximate front cox. Metathoracic side-pieces linear, Abdomen rather short, the third and fourth 
segments respectively shorter than the others. ‘ibis narrow, a little wider apically, upper margin with 
two small teeth ; apex truncate, its lower angle shortly spined. ‘arsi short, their first three joints equal, 
the fifth nearly as long as the others together. 
This genus is established for two species which resemble a Dryocetes, but differ 
in the structure of the antenne and legs. The joints of the funiculus are difficult to 
separate even with a high magnification; and as each species is represented by a 
single example, the mouth-parts have not been examined. 
1. Dendroterus mexicanus, sp. n. (Tab. VII. fig. 25.) 
Oblongus, subnitidus, piceo-ferrugineus, pallide pilosus, antennis pedibusque testaceis ; prothorace semielliptico, 
latitudine longiore, medio obtuse transverse elevato, granulato, linea media prope basin levi; elytris 
grosse lineato-punctatis, interstitiis subequaliter scriato-punctatis, apice subdeplanato, margine postico 
obtuso. 
Long. 2°3 millim. 
Oblong, slightly shining, piceo-ferruginous. Front flattened, rugose and densely villous; eyes emarginate- 
oval; antenne testaceous-brown. Prothorax longer than broad, widest towards the base, the sides and 
apex subelliptically curved, the hind angles subrectangular, the base truncate; disc with an obtuse 
transverse median elevation, granulate except over the basal half of the median line, more strongly 
towards the apex, the pubescence short, scanty. Scutellum small, rounded. Elytra as wide as and a 
third longer than the prothorax, with rounded-rectangular and slightly callous humeral angles, the sides 
subparallel, the hind margin subtruncate, its lateral angles rounded; surface with rows of coarse 
punctures, the sutural row scarcely impressed, the interstices narrow, flat, subrugose, with single rows 
of less frequent but scarcely finer setiferous punctures; declivity convex above, almost vertical and some- 
what flattened below, strongly punctured. Underside black, pubescent. Legs testaceous. 
Hab. Mexico, Tehuantepec in Oaxaca (Hége). 
A single example has been obtained. ‘The elytral punctures are coarse, deep, and 
not close, so that the distinction between those of the striz and interstices is not readily 
noticeable. The frontal villosity is, no doubt, a sexual character. 
2. Dendroterus sallzi, sp. n. 
Oblongus, subnitidus, testaceus (?subimmaturus); prothorace semielliptico, granulato, linea media nulla; 
elytris fortiter punctato-striatis, interstitiis angustis, subconvexis, seriatim setosis, apice fortiter declivi, 
subconvexo, margine postico rotundato. 
Long. 1°9 millim. 
Oblong, stout, slightly shining, testaceous (perhaps immature). Front impressed, set with rather close, erect, 
pale pubescence. Prothorax scarcely longer than broad, slightly but perceptibly narrowed in front, with 
less trace of the discal elevation than in D. mevxicanus, its surface completely granulate, with no median
