1. Dendrosinus transversalis, sp. n. (Tab. VI. figg. 16; 16 a, antenna.) 
Convexus, ovatus, niger, opacus, fronte dense breviter aureo-villosa, antennarum clava transversali, oculis 
integris ; prothorace valde transverso, rudi; elytris striatis, interstitiis fuliginoso-setosis. 
Long. 4°3 millim. 
Convex, ovate, black, dull. Front flattened, with dense short upstanding aureous pubescence and no median 
smooth line; antenne ferrugino-testaceous, the club large, broader than long, strongly rounded laterally 
and truncate at the apex, the sutures curved, the third bisinuate. Prothorax strongly transverse, rounded 
at the sides and subconstricted towards the apex, its anterior margin somewhat obtuse, the base bisinuate, 
very oblique on either side and produced backwards between the elytra; surface convex, opaque, with 
short pale pubescence, and close very shallow confluent punctuation, the median line indistinctly 
elevated at the base only. Scutellum small, convex, rugose. Elytra wider than the prothorax, their 
basal margins oblique, sinuate, elevated and crenate, the apices separately rounded; surface with 
indistinctly punctured incised stria, the interstices wide, flat, finely granulate, more strongly towards the 
base, set with very short decumbent hairs; fuliginous-black or fuscous, lighter at the base and sides. 
Abdomen convex, subnitid, weakly punctured, with short yellowish pubescence. Legs piceous, the 
tarsi lighter. 
Hab. Mexico, San Andres Tuxtla (Sal/é). 
Two examples. ‘The large entire eyes and transverse antennal club are important 
distinguishing features *. 
* The remaining differential characters of the other species are as follows :— 
Dendrosivus globosus, Eichh. 
Ovalis, convexus, sublongior; fronte parcius pallide villosa, linea media indistincta; antennarum clava 
ferruginea, oblonga, suturis vix curvatis ; oculis haud permagnis, antice sinuatis, prothoracis linea media 
distinctius elevata ; elytrorum setis fulvis. 
Long. 4°3 millim. 
Hab. Vuyezuria (Moritz, in Mus. Vind, Ces.). 
This species was described from ‘‘ America borealis,” but has not yet been recognized in the United States. 
I have been able to see the type, now in Herr Schaufuss’s collection. 
Dendrosinus vittifrons, sp. n. 
Late ovatus; fronte pube brevi velutina, vitta media subelevata rudi excepta, ornata; oculis antice 
emarginatis; antennis piceis, clava oblonga, sutura 3° sinuata; prothoracis linea media per totum 
distincte subelevata, pube fusca; elytrorum margine basali fortius crenato, interstitiis ad basin magis 
granulatis, postice minus dense pilosis et opacissime subsericeis, setis omnibus nigris. 
Long. 4-4°6 millim. 
Hab. Braziz (in Mus. Oxon., et in coll. Blandford). 
Dendyosinus puncticollis, sp. n. 
Minor, fronte subglabra, rudi, supra os modo rugose punctata, et linea media abbreviata notata ; oculis antice
