COLEOPTERA 215 



(63) Proterlmms sternalis Sharp. 



Proterhintis sternalis Sharp, Tr. Ent. Soc. London, 1879, p. 98. 



(Plate IX. figs. 19 and 19 a. t) 



This species is remarkable for the great developement of the eyes, and tarsal lobes, 

 the concavity of the prosternum from the front to the base, and the unusual clothing of 

 the intermediate tibiae, which bear long and soft hairs, instead of the usual short and 

 stiff setae. The ridges of the elytra are quite well-marked, especially when these are 

 observed in lateral view. Length from 2 '2 — 2 '3 mm. 



Hab. Maui, Haleakala (4000 — 5000 ft.) ; not very common, only about 20 

 examples were taken. 



{64) Proterhintis sternalioides, sp. nov. 



Sat latus, nigricans vel rufo-niger, antennis, pedibus, elytrisque plus minusve 

 rufescentibus, his riigro-notatis, praecedenti sp. cognatissimus. Oculi magni. Prono- 

 tum antice constrictum, fortiter 3-impressum, minus latum. Elytra subinaequalia, 

 pallide squamosa, setisque erectis elongatis vestita, basi scutellum ju.xta utrinque 

 tuberculata, humeris fortiter productis. $%. Long. 2'2 — 375 mm. 



This species is extremely like P. sterna/is, which it resembles in colour, form, 

 &c. The longitudinal ridges of the elytra are rather less pronounced, and the face 

 of the $ (including the rostrum) is evidently more elongate. The rostrum of the 

 $ is slightly longer, its surface slightly rugulose all over. The intermediate tibiae 

 are clothed with shorter setae, and the lobes of the front tarsi of the ^ are of rather 

 different form, being rather more narrow and elongate, the whole joint having a less 

 quadrate form. The hind coxae of the d' are distinctly more widely separated, and the 

 prosternum is impressed only along its anterior margin, not longitudinally sulcate down 

 the middle from front to base as in Z'. sternalis. 



Hab. Maui, Haleakala (5000 ft.) ; several examples taken, probably in company 

 with P. sternalis. 



(65) Proterhinus microtarsus, sp. nov. 



Atro-piceus, elytris rufescentibus, nigro-notatis, antennis pedibusque totis rufis. 

 Antennae elongatae, graciles, articulo i elongato sed robusto, quam tertius longiore, 

 caeteris elongatis, clava gracili, distinctissime 3-articulata. Oculi magni. Vertex a 

 fronte capitis haud distinctus. Pronotum perinaequale, antice subito fortiterque con- 

 strictum. Elytra squamulosa, longitudinaliter subcarinulata (lateraliter compressa), setis
