COLEOPTERA 151 



(2) Nesotocus nczuelli, sp. nov. 



Praecedenti cognatissimus. Differt statura majore, antennaruni scapi apice magis 

 incrassato, funiculo densius longiusque piloso, articulo secundo pro primo magis elongate. 

 Z- Long. 26 mm. 



The single t of this species I believe to be distinct from N. muiu-oi, and not 

 merely a very large and finely developed example of that species. Besides the 

 characters given above the apical joint of the fnnicnlns of the antennae is nearly equal 

 to the basal portion of the club, which is clothed with sub-erect hairs (the apical portion 

 being densely covered with appressed pubescence). In N. munroi the apical joint of 

 the funiculus is very greatly shorter than the basal portion of the club. 



Hab. Maui. A single example has been taken by Bro. Matthias Newell in the 

 lao valley. 



(3) Nesotoctis kauaiensis, sp. nov. 



Praecedentibus simillimus, niger, pubescentia flava ornatus. Differt ^ antennis 

 haud propius ad apicem rostri quam ad oculos insertis, % rostri parte postantennali 

 minus fortiter denseque punctata. Long. 13 — 16"5 mm. (Plate VIII. fig. 5.) 



The ^ of this species is very distinct from either of the preceding, by the different 

 point of insertion of the antennae, this being nearly equidistant from the eyes and apex 

 of the rostrum. The % is much more difficult to separate, but the basal portion of the 

 rostrum appears to be smoother, and more finely and less closely punctured. In fresh 

 examples the pubescence is decidedly more deeply yellow, and that on the elytra is 

 rather more extensive. 



Hab. Kauai (4000 ft.). 



DvsoMMA, gen. nov. 



Corpus sat gracile, cylindrico-fusiforme, haud pubescens. Rostrum elongatum, 

 leviter curvatum, pronoto longitudine subaequale, parte praeantennali basali parte sat 

 latiore. Oculi parvi, subobsoleti. Antennae longe ante medium rostrum insertae, 

 funiculi 7-articulati articulo basali elongato, secundo bis longiore, hoc tertio longiore, 

 capitulo elongato-ovali. Pronotum magnum, elongatum, elytris latius, antice fortiter 

 angustatum, vix constrictum. Uncus tibiarum anticarum apicalis validus. Tarsi brevi- 

 ores, articulo tertio parvo, lobis brevissimis. Unguiculi graciles, breves. Coxae omnes 

 late separatae, metasterno longo. Abdominis segmentum basale inter coxas posteriores 

 antice rotundatim productum. Elytra angustiora, lateribus subparallelis. Scutellum 

 patens.
