196 FAUNA HAWAIIENSIS 



(22) ProterJiinus laticornis, sp. nov. 



Minor, angustulus, rufescens, capite femoribusque, et nonnunquam etiam pronoto, 

 obscurioribus, elytris circa medium utrinque nigro-maculatis. Antennae ^ nigrae, basi 

 rufa, ab articulo tertio vel quarto sensim usque ad apicem incrassatae, clavam quasi 

 perelongatam formantes. Species pallida squamosa, faciem P. serricornis omnino 

 habens, sed antennis longe aliter formatis, femoribus posterioribus valde incrassatis 

 distinctissima. Z- Long. 2 — 2-25 mm. (Plate IX. fig. 5, <J.) 



This minute but very remarkable species is clearly allied to P. serricornis, with 

 which it agrees in colour, clothing, and shape. Probably on the average it is of rather 

 larger size. The joints of the antennae from the fourth or fifth become gradually wider 

 to the apex, the whole forming as it were a very gradual and elongate club. The lobes 

 of the front tarsi are minute, and the hind femora very strongly incrassate. The female 

 which no doubt belongs to this species is quite unlike the <J in its antennal characters, 

 since the intermediate joints are comparatively slender, and there is a distinct and 

 strongly developed 3-jointed terminal club. This sex is therefore very similar to 

 P. serricornis $, from which it may be known by the more strongly incrassate 

 femora. 



Hab. Kauai, Halemanu (4000 ft.). 



(23) ProterJiinus eurhopahcs, sp. nov. 



Piceus, elytris plus minusve rufescentibus nigro- vel fusco-notatis, forma fere spp. 

 2 praecedentium, sed plerumque colore obscuriore. Antennae ^ graciliores, basi rufa, 

 clavae (distinctissime 3-articulatae) articulis latis. Femora postica minus fortiter 

 incrassata. Z- Long, vix 2 — 2-2 mm. (Plate IX. fig. 7, Z antenna.) 



Closely allied to the two preceding species, the general form and appearance being 

 the same, the colour perhaps more obscure. The Z has the antennae comparatively 

 slender, indeed more nearly resembling the % of the preceding two species, and the club, 

 consisting of three very distinct joints, is unusually developed. The eyes and tarsal 

 lobes are small, the posterior femora not very strongly incrassate. Two females 

 taken in company with these males are no doubt of the same species, resembling 

 them very closely in all respects, except for the usual sexual differences in the 

 rostrum. 



Hab. Kauai, Makaweli, at an elevation of 2000 — 3000 ft.
