196 Bracksurn anp SHAarP—On some New Species and Genera of Coleoptera. 
Thorax dark red on the middle, deep black at the sides, broadly cristate along 
the middle, less distinctly crested on each side, the spaces between the crests bearing 
each a longitudinal vitta of scanty white hair; elytra broadly tawny, yellow at the 
sides; this colour continued to the base along the shoulder, but the shoulder ex- 
ternal to this colour is blackish, and the yellow colour also re-appears round the 
scutellum, behind which the surface is blackish. This colour extends backwards 
along the suture, reaching the apex, but is more dilute behind. A vitta of white 
hairs extends from the apex along the suture, and in front becomes broader, till 
near the scutellum it diverges laterally on either side, so as to be furcate. The 
middle and hind legs are extremely elongate, their femora intensely black, 
incrassate, but not clavate, although they have a slender basal portion, which is 
yellow in colour. The tibiz and tarsi are hirsute, and the four or five basal joints 
of the antennz are much clothed with hair; that on the legs isin greater part pale 
in colour, but on the antenne is black. In the male, the antenne reach about as 
far back as the extremity of the elytra, but in the female are considerably shorter. 
In the former sex the hind body is short and curvate, and composed of five segments; 
but in the female it extends as far as the apex of the elytra, is semimembranous in 
texture, and possesses six segments. The male apparently varies much in size. 
Mr. Blackburn has a specimen of this sex 18 m.m. in length. The largest of the 
two he has sent me is 13 m.m. long. 
Found in Mauna Loa, Hawaii, on a species of Acacia, at an elevation of about 6000 feet.

Clytarlus filipes, n. sp.—Minor, subdepressus, opacus, sordide niger, albido- 
setosus, in elytris subfasciatus, femoribus parte basali testacea, antennis tibiis 
tarsisque ex parte majore fuscis, antennarum articulis basalibus ad basin, genicu- 
lisque testaceis. Long. 51—7 m.m. 
Thorax along the middle with some short transverse ridges, of which the most 
anterior is strongly elevated. Elytra very densely but not coarsely punctured, so 
as to be finely rugose ; less attenuated behind than in the other species, clothed 
rather sparingly with Sato setosity, which forms two or three broad, vague, trans- 
verse bands. Femora of hind and middle legs, with an elongate, very slender 
basal portion, which is pale yellow in colour; the tibiz dark, but paler at the base, 
excessively slender; hind tarsi fuscous, slender, but little hirsute. The male has 
the antennz considerably longer than the female, extending nearly to the apex of 
the elytra, and the apical part of the femora more swollen. The hind body is in 
each sex rather broad and flat, but is curved downwards at the extremity in the 
male. In the female it isratherlonger. In the former sex it terminates as a large 
bi-lobed, or deeply-notched process, which appears to be retractile. The species is 
allied to C. fragilis. 
Found in Hawaii on the same tree asC. blackburni ; in fact, in company with it. ahs
