lOO FAUNA HAWAIIENSIS 



and the punctuation of the elytra denser ; the punctuation on the brown band behind 

 the scutellum denser and finer. The antennae are rather long, yellow, but little thicker 

 at the tip. The pronotum is transversely evenly convex without median or lateral 

 crests, there being a single ante-median, and two smaller post-median transverse eleva- 

 tions. The punctuation on the apical parts of the elytra is obsolete ; the colour of the 

 hairs forming the obscure elytral fasciae is yellow rather than white ; the pubescence on 

 the femora is long, and that on the under surface of the body is long and scanty. The 

 stalk of the hind femur is very pallid and long, the club is abrupt, brown. Only five 

 abdominal segments can be seen in the male, and the hind-margins of the dorsal and 

 ventral plates of the fifth are broad and nearly straight. 

 Only two specimens of the male sex have been found. 



A third specimen, from Mauna Loa 17. vii, 92, is I have no doubt the female ; it is 

 much larger, and has much less abruptly clubbed femora. 



Hab. Hawaii ; Mauna Loa (W.) Sepr. 1892, 4000 ft. ; Hualalai, 5, viii, 92, 5000 ft. 

 On Acacia koa. 



(5) Clytarhis obscurus, sp. nov. 



Minor, rufo-obscurus, vel fuscus, albido-pubescens, in elytris subfasciatus, antennis 

 pedibusque testaceis, femoribus clava fusca. Long. 4^ — 6-J millim. 



Van Antennis pedibusque ex parte majore nigris. 



This is an excessively variable species in the colour of the elytra, legs and antennae, 

 in the length of the white hairs, and in the fasciae of the elytra ; it also varies consider- 

 ably in the elongation of the legs ; the variation in size seems to be less than it is in 

 some other species. The thorax usually appears somewhat depressed longitudinally on 

 each side of the middle, so that the middle appears slightly crested, but the transverse 

 elevations on the middle are very small. The legs bear a very distinct, fine long 

 pubescence ; the hind femora have a long basal stalk yellow in colour, and a darker, 

 moderately long and abrupt club, which is much thicker and more abrupt in the male 

 than it is in the female. The genital segment of the male is simple. The punctuation 

 in this species is less dense and fine than in C. Jilipes and mediocris, and the simple 

 genital .segment of the male clearly distinguishes C. obscuncs from both those species. 

 The paler varieties closely resemble C. fragilis and C. dedilis, but may be separated 

 therefrom by the less abrupt club of the femora, and by the darker colour. 



Hab. Kauai ; in several localities at a height of about 3000 feet, Perkins ; nearly 

 fifty specimens. On Acacia koa.
