COLEOPTERA 2 1 3 



(59) Proterhinus comes, sp. nov. 



Major, piceus, vel obscure rufescens, subbrunneo-squamosus, pronoto elytrisque 

 setis erectis crebre conspicueque vestitis. Oculi sat magni, fortiter prominentes. 

 Antennae graciles, articulo secundo brevissimo, clava gracili, elongata, 3-articulata. 

 Pronotum antice fortiter angustatum et transversim impressum, impressionibus pos- 

 terioribus rotundatis et distinctis. Elytra dense punctata, longitudinaliter subcari- 

 nata, margine basali scutellum juxta utrinque tuberculato, humeris fortiter acute 

 productis. Pedes omnes conspicue setosi, lobis tarsorum anticorum minoribus. ^. 

 Long. 3-5—4 mm. 



Apparently closely allied to P. validus, but a considerably smaller insect 

 and of less elongate and oblong form. The antennae are quite differently formed, 

 the intermediate joints being slender and elongate. The eyes also, and the lobes 

 of the front tarsi, are less developed, and the longitudinal ridges of the elytra 

 generally more obscure. 



Hab. Maui. Three examples of the $ taken on Haleakala (4500 — 5000 ft.) ; 

 it is probably a variable species, as these examples do not altogether agree in 

 small points. 



(60) Proterhinus lecontei Sharp. 



Proterhinus lecontei Sharp, Tr. Ent. Soc. London, 1879, p. 99 ; Tr. Dublin 



Soc. III. 1885, PI. V. fig. 42 ?, fig. 43 t. 

 Varies greatly in size, some examples being only about half the bulk of a normal 

 specimen. Length (excluding rostrum) 3*2 — nearly 5 mm. 



Hab. Maui, Haleakala (5000 ft.) ; not rare, but only on one species of tree, of 

 which I neglected to obtain a specimen for identification. 



(61) Proterhinus sharpi, sp. nov. 



Ferrugineus, elytris saepe plus minusve nigricantibus, ferrugineo-squamosus. 

 Antennae rufescentes, sat graciles. Oculi fortiter prominentes. Pronotum minus 

 latum, dense squamoso-vestitum, 3-impressum, antice angustatum. Elytra suboblonga, 

 lateribus subparallelis, utrinque longitudinaliter carinata, carinis postice abrupte trun- 

 catis, humeris sat fortiter productis. $ %. 2"6 — 375 mm. (Plate IX. fig. 17. $.) 



In the form of the elytra this species can only be compared with P. lecontei, 

 the longitudinal ridges of the elytra being well-marked and abruptly vertical behind, 

 so that in a posterior view each appears as a strongly elevated tubercle. In
