Loiigicorn Coleoptcra. 207 



This species lias aloni^ the middle of the thorax an 

 elevation which is only distinct in front and behind, and 

 commences abruptly near the front margin, so that when 

 looked at from the front the thorax appears tuberculate 

 close to the front margin. The elytra are rather coarsely 

 sculptured, but the sculpture is indistinct and obsolete at 

 the extremity ; their colour is not easy to describe, is 

 yellowish, suffused with black in such a way as to form 

 some marks, the most conspicuous of. which is a black 

 band on each in front of the middle, the two marks when 

 united forming a conspicuous V-like mark behind the 

 shoulders ; the wing cases are also flecked with small spots 

 of white pubescence, Avhich, however, are wanting from 

 the black band, and therefore render it still more con- 

 spicuous ; there is also a large but indefinite black mark 

 near the extremity of each. 



I have a pair of this species before me ; the male is 

 considerably larger than the female, and has a greater 

 development of the middle and hind legs. 



Mr. Blackburn has sent me this species, as No. 100, 

 and informs me that in the middle of 1877 he captured 

 half a dozen specimens running with extreme rapidity on 

 some fallen trunks of trees high up on a mountain in the 

 island of Oahu, about six miles from Honolulu ; and that 

 soon after he found a single mutilated individual, in 

 another locality, again high up on a mountain about 

 twenty-five miles from Honolulu. 



Clytarlus cristatus, n. sp. Angustulus, gracilis, ru- 

 fescens; prothorace medio longitudinaliter elevato et 

 scabroso, elevatione anterius per-conspicuo, utrinque sub- 

 sulcato, dorso, parcius albido-squamoso; elytris gracilibus, 

 etiam ad humeros hand latis, versus scutellum singulo 

 subelevato, variegato-setosis ; femoribus intermediis et 

 posterioribus ad apicem fuscis, apice summo conspicue 

 albido-vestito ; tarsis posterioribus albido-hirsutis. Long. 

 8 mm.; lat. 1| mm. 



This species, though very distinct from C. robustus, 

 much resembles it in most of its characters. The basal 

 portion of the elytra is irregularly covered Avith white 

 hairs or scales, and there are pale yellow ones along the 

 suture, and also some of this colour about the basal 

 ])ortion of the sides ; the white scaled basal portion of the 

 Aving cases is followed by an irregular band covered Avith 

 fine dark hairs, and behind is an indefinite small trans-
