222 FAUNA HAWAIIENSIS 



to be a quite distinct species. No doubt this will prove to be a variable character, 

 and probably common to either sex, as in many other species of the genus. The 

 species is not closely allied to any other of those taken on Maui, but rather re- 

 sembles P. vestitns of Oahu and its allies on Hawaii. It is remarkable for its red 

 colour, entirely red antennae, the club of which is hardly more than 2-jointed, since 

 (especially in the $) the ninth joint is but little different to the preceding, and the 

 strongly clavate black femora in either sex. The elytra have a distinct oblique post- 

 humeral elongate spot of pale squamosity, and several small roundish ones behind 

 these, they are subcompressed at the sides but can hardly be said to bear longi- 

 tudinal ridges. Their puncturation is close and coarse, and their form in the 

 $ is very long and narrow. 



Hab. Maui, lao valley, March 1S94. 



(76) Proterhinus osculans, sp. nov. 



Parum latus, piceus, rufo-piceus vel rufescens, pedibus plerumque rufis, antennis, 

 articulo basali saepe excepto, nigris. Oculi minimi sed prominentes. Antennae 

 graciles, clava vix plus quam 2-articulata, articulo 8° et 9° inter se simillimis (hujus 

 apice paullo latiore). Pronotum parce squamosum, antice transversim impressum, 

 depressionibus posticis vel absentibus vel fere obsoletis. Elytra parum squamosa, 

 post media saepe squamositate pallida binotata, setis erectis brevioribus vestita, 

 densissime grosse rugoso-punctata, humeris acutis et productis. Femora omnia con- 

 spicue gracilia. ^%. Long. 2 — 2 '5 mm. (Plate X. fig. 6.) 



This is very unlike any of the other Maui species, and it does not indeed appear 

 to be very closely allied to any other species of the genus. It is chiefly remarkable for 

 the unusually slender femora, the hardly more than two-jointed antennal club (the tenth 

 joint being much wider than the ninth, and this not very different to the preceding), and 

 the somewhat long rostrum of the %, which is narrowed towards the base, the surface 

 being entirely longitudinally rugose. The eyes are quite small, but prominent, the 

 squamous covering of the insect is sparse, revealing the dense puncturation, the surface 

 itself being sometimes even shining, and set with shortish erect setae. The elytra are 

 without longitudinal ridges, their humeral angles acute and somewhat produced. 

 Usually the entire insect is covered when captured with an exudation, which conceals 

 all the structure, and is difficult to remove. 



Hab. Maui, Haleakala (5000 ft.). About 20 examples taken.
