Colcoptera from the Haioaiian Islands. 99 



towards the suture ; there is an indistinct darker patch on 

 the side of each wing case about the middle, and on this 

 the punctuation appears coai'ser than elsewhere. 



Found on dead wood in the forests at an elevation of 

 4,000 ft. on Haleakala, Maui. The pair sent represent 

 the sexes ; the unrostrate individual is smaller than the 

 other, with the anterior legs rather shorter, and the lobes of 

 the 2nd tarsal joint on the front feet unusually developed. 

 Sent as Nos. 1*67 and 1G8. 



Proterhinas Lecontci, n. sp. Major; parum dense 

 griseo-squamosus; prothorace inasquali; elytris basi emar- 

 ginato, et quasi quadridentato, pone medium valde tu- 

 berculato elevatis, setis erectis sat conspicuis. Long. 

 4 — 4f mm. 



The antenna ai-e largely developed, and are about 

 intermediate between red and black in colour. The eyes 

 ai'e large. The thorax is constricted in front, and bears 

 three very large impressions, the anterior one being ex- 

 cessively large, the sides and front margin are marked by 

 some curved erect seta3. The elytra are emarginate at 

 the base, with the humeral angles excessively prominent, 

 and there is a prominent tubercle on each side of the scu- 

 tellum projecting somewhat forwards as well as upAvards; 

 along the middle of each wing case is a longitudinal 

 elevation, terminating some distance before the extremity 

 very abruptly, and so forming a very prominent tubercle ; 

 the punctures are distant but distinct, and rather evenly 

 distributed. 



Beaten from dead wood in the forests at an elevation of 

 about 4,000 ft. on Haleakala, Maui. No. 165. 



Ohs. — This is by far the largest species of the genus 

 yet found, and is the most highly developed and most 

 sexually differentiated, and at the same time seems to 

 make the nearest approach to Aglycyderes ; it may, 

 perhaps, have to be treated as a distinct genus. The 

 epipleura? of the elytra are less rudimentary than in the 

 allies, and the coxte are not so widely separated, especially 

 in the sex without rostrum. In the other sex the beak is 

 highly developed. P. sternalis shows an approximation 

 to Lecontei, however, and if one or two intermediate 

 species are discovered, as is quite possible, P. Lecontei 

 will have to remain united in a first synthesis, with its
