148 FAUNA HAWAIIENSIS 



Elytra ac pronotum aeque lata. Scutellum conspicuum. Tarsorum articulus tertius sat 

 latus, bilobatus. Uncus tibiarum anteriorum apicalis validus. Femora robusta. Coxae 

 omnes late separatae. Metasternum satis longum. Abdomen subtus pubescens, fortiter 

 punctatum. 



A genus, the species of which is of small size, and apparently without any allied 

 form known from elsewhere. It is very remarkable for the short wide rostrum, the very 

 large, but not prominent eyes, and the dense covering of golden pubescence. In the 

 testaceous colour, and the clothing, these insects have an extraordinary resemblance to 

 the insect, for which I have made the genus OrotJireptes, but that has a totally different 

 form of rostrum, and a 5-jointed funiculus, and differs in many other respects. Probably 

 in habits the two are identical. 



Deinocossonus is a form of excessive rarity, or at least very difficult to procure, and 

 the pubescence is so easily removed, that I have been unwilling to subject the few 

 specimens taken to much manipulation. 



(i) Deinocossomts nesiotes, sp. nov. 



Angustus, testaceus, aureo-pubescens, capite rostroque nigris. Pronotum dense, 

 nee profunde punctatum, inter puncta subtilissime rugulosa. Elytra striata, striis obscu- 

 rius, plus minusve evidenter punctatis, interstitiis obscure punctulatis, et pubescentibus. 

 Femora anteriora supra testacea, parte inferiore nigricante. Long, (rostr. incl.), 2 '5 — 

 vix 3 mm. (Plate VIII. fig. 3 ; 3a, antenna.) 



Var. a. elytrorum striis haud evidenter punctatis, rostri parte apicali testacea. 



Var. y8. rostro et capite nigris, femora omnia cum tibiis nigricantia. 



Hab. Oahu. Two examples taken together at an elevation of 3000 ft. on Kaala 

 mountain. Var. a. Kauai, 4000 ft. ; Oahu, Waianae mountains. Var. ^. Hawaii. 

 One specimen at Kilauea. 



Haloxenus, gen. nov. 



Corpus elongatum, gracile, fusiforme, haud pubescens. Rostrum latum, breve 

 subconicum (sc. lateribus ad apicem evidenter convergentibus), a capite minus distincte 

 divisum. Oculi rotundi, latissime separati, a pronoto sat distantes. Antennae paullo 

 ante medium rostrum insertae, funiculi 7-articulati articulo primo robusto, caeteris 

 longiore, secundo caeterisque brevissimis, capitulo sat magno, apice acumlnato. Pro- 

 notum elongatum antice angustatum, vix constrictum. Pedes sat robusti ; tarsi breves, 

 articulo tertio parvo, haud evidenter bilobato, articulo ultimo elongato, caeteris conjunctis 

 haud minus longo. Metasternum perlongum. Coxae omnes late separatae. Elytra 

 elongata, angusta, lateribus parallelis. Scutellum patens. 



This genus comes nearest to Eutornns WolL, but has the rostrum narrowing to 

 the apex, and the point of insertion of the antennae is different.
