I50 FAUNA HAWAIIENSIS 



Nesotocus, gen. nov. 



Forma subfusiformi, statura magna. Rostrum cylindricum, perlongum, maris 

 rugose sculpturatum, saepissime spinulosum, feminae parte praeantennali laevi, nitida, 

 impunctata. Oculi magni, convexiusculi, a pronoto sat distantes. Antennae longissimae, 

 graciles, maris paullo ante vel fere ad medium rostrum, feminae longe post medium 

 insertae, funiculo (^) perspicue piloso, 7-articulato, articulis basalibus fortissime elongatis, 

 capitulo elongato, subfusiformi. Pronotum antice fortiter angustatum, truncato-conicum. 

 Scutellum patens. Pedes longissimi, femoribus anterioribus ^ gracilioribus, % robusti- 

 oribus et magis incrassatis, tarsorum articulo primo et secundo elongatis, tertio late 

 bilobato, articulo ultimo gracili elongato, apicem versus crassiore, unguiculis longis et 

 curvatis. Coxae anteriores (necnon etiam intermediae et posteriores) late separatae. 

 Metasternum sat longum, postice subangulariter emarginatum, medium longitudinaliter 

 impressum vel sulcatum. Abdominis segmentum primum ventrale secundo paullo 

 longius, tertium una cum quarto hoc paullo brevius, segmentum apicale ^ latius $ minus 

 late rotundatum. Elytra et pronotum pube pallida decorata, hoc et illis subaequilatis. 



There is apparently no known ally to the three remarkable insects for which the 

 above genus is formed. They all live in the wood of the tree Cheirodendron, and, I 

 believe, of another tree which has a considerable resemblance to that genus. In 

 superficial appearance the three species almost e.xactly resemble one another, and this 

 is rather that of Erirhinini than Cossonini. 



( I ) Nesotocits imtnroi, sp. nov. 



Niger, pubescentiae pallidae maculis ornatus, antennis tarsisque nonnunquam 

 rufescentibus. Rostrum $ (saltem in exemplis majoribus), rugoso-sculpturatum, utrinque 

 serrato-spinosum, in exemplis parvis vi.x plus quam simpliciter punctatum, % parte prae- 

 antennali laevi impunctato. Antennae t evidenter propius ad apicem rostri quam ad 

 oculos, % longe post medium rostrum insertae. Pronotum sat dense punctatum, antice 

 fortiter angustatum, conico-truncatum. Elytra striata, striis parum fortiter punctatis, 

 apicem versus compressa. Long, (rostr. incL), ^ majoris 21 mm., ^ minoris i2'5 mm. ; 

 % 15 mm. 



Ill-developed males have the front femora more incrassate than large examples, 

 tending to resemble the % in this respect, as also to some extent in the smoother 

 rostrum. 



Hab. Hawaii, Maui. Various localities on Hawaii (2000 — 4000 ft.) ; Kohala, 

 Kau, Puna; Haleakala on Maui. This species was given to me, soon after my arrival 

 in the islands, by Mr G. C. Munro, who obtained specimens in the Kohala mountains, 

 and I have named it after this excellent ornithologist. A fragment (elytra and sternum) 

 found in the mountains of Molokai may belong to this species, but the pubescence is 

 more deeply yellow.
