BLackBuRN AND SHAaRP—On some New Species and Genera of Coleoptera. 155 
Eopenthes ambiguus, n. sp.—Subnitidus; castaneus, capite nigro, antennis 
(basi excepta) picescentibus, corporis dimidio longioribus; capite prothoraceque 
crebre subtilius punctatis, tenuiter pubescentibus; elytris striatis, striis fortiter 
seriatim, interstitiis vix distincte, punctatis; his tenuiter pubescentibus. Long. 
7 m.m. 
Antennz reaching back by the length of the apical three or four joints beyond 
the end of the hind angles of the thorax; second and third joints short, equal. 
Thorax not much narrowed to the front, its sides being nearly straight, the carina 
of the hinder angles scarcely discernible. The prosternal process does not differ 
much from that of E. kone. 
A single specimen was taken by sweeping at the head of the Palolo Valley, Oahu, at an elevation of 
about 2000 feet.

Eopenthes satelles, n. sp.—Elongatus, subparallelus, subnitidus, niger, an- 
tennis pedibus elytrisque testaceis, horum disco fusco; prothorace haud dense 
punctato ; elytris fortiter striatis, striis fortiter interstitiis obscure punctatis ; his 
pubescentibus. Long. 8 m.m. 
Antenne rather slender, just surpassing the end of hind angles of thorax; second 
and third joints short, equal. 
This species is somewhat closely allied to E, debilis, Sh., from which it differs 
not only in colour and comparative length of second and third joints of antenne, but 
also in the following respects :—the elytra are decidedly more elongate and paral- 
lel, being therefore much less acuminate behind; and they are much more deeply 
striated, with the interstices more distinctly punctured, and not so flat. The 
prosternal process is similar to that of E. debilis, Sh. 
The single specimen retained by me, taken in company (?.¢. at the same 
stroke of the beating stick), and believed to be conspecific with the specimen 
described by Dr. Sharp as E. basalis, presents some differences which I have re- 
garded as probably sexual. It is slightly larger, and the antennz reach back quite 
to the end of the hind angles of the thorax, having joints four to ten considerably 
widened and strongly compressed. Unfortunately I failed, before sending the 
specimen to Dr. Sharp, to notice the characters which he with his well-known 
acumen has observed in the prosternal process; but if I read his description aright, 
the specimen which forms the subject of this note agrees in that respect with that 
described by him as E. basalis; having the prosternal process abruptly and angu- 
larly perpendicular behind the front coxz, and then again produced backwards on 
a lower plane. 
A single specimen was obtained by sweeping ferns near a place called Koele, on Lanai, at an 
elevation of about 2000 feet.
