COLEOPTERA 225 



Closely allied to P. dispar. Sharp, of which species it might be regarded as a 

 highly-developed local race. The t is remarkable for the development of the rostrum, 

 which is less short than usual, and the extreme thickness of the femora. The eyes are 

 large and very prominent, the antennae long and very slender, the lobes of the front 

 tarsi strongly developed, being unusually wide, and the joint strongly transverse. The 

 tibiae have a clothing of somewhat fine hairs. These are also mainly the characters of 

 P. dispar, but that species may be distinguished by the less elongate and slender third 

 joint of the antennae, and indeed generally by the following joints also being shorter, 

 and it never attains the size of the larger e.xamples of P. persiniilis. 



Hab. Maui, lao valley ; attached to JVikstroemia. 



(81) Proterhimis nivicola, sp. nov. 



Totus niger, angustus, parce squamosus. Antennae nigrae, graciles, breviores, 

 clava vix 3-articulata. Oculi minores, minus prominentes. Pronotum subelongatum, 

 minus distincte 3-impressum, parum squamosum, sed ad angulos posteriores macula 

 albido-squamosa signatum. Elytra angusta, fortiter punctata, parcius obscure sub- 

 maculatim squamosa, setis erectis brevissimis et perinconspicuis, basi utrinque scutellum 

 juxta distincte tuberculata, angulis humeralibus fere rectis. Femora omnia minus fortiter 

 clavata, lobis tarsorum anticorum minutis. %. Long, vix 3 mm. 



Only a single example of the % of this species having been taken nothing is known 

 as to its variability. It is chiefly distinguished by its general black colour and narrow 

 elongate form, but possesses no very remarkable characters. The ninth joint of the 

 antennae is but little different to the preceding, so that the club is apparently 2-jointed. 

 To the characters given above it may be added that the rostrum is rather short, shining, 

 and with the longitudinal grooves somewhat strong, and that the basal ventral segment 

 of the hind-body is strongly and closely punctate over its whole surface. The species 

 is of interest as being the only one found far above the limit of the true forest. 



Hab. Maui, Haleakala (9000 ft.) ; taken not many weeks after the disappearance 

 of a heavy fall of snow.

Proterhimis pimctipcnuis Sharp, Tr. Ent. Soc. London, 1881, p. 530. 



The examples which served for the original description of this species were large 

 and well-developed specimens. It is, however, very variable, the development of the 

 antennae being much less strong in some examples than in others. The puncturation 

 of the elytra, which is in reality very coarse and close, appears much less striking in 

 individuals in which the squamous covering is more abundant, and frequently the insect
