194 BiackBuRN AND SHARP—On some New Species and Genera of Coleoptera. 
This insect resembles X. immaturus, mihi, in having on the hinder part of each 
of the elytra about three rows of nearly equal tubercles; but it differs in that the 
tubercles are conspicuously smaller than in X. immaturus, and also in being 
an extremely narrow, cylindrical, and less shining species, without any trace 
of striz on the elytra where the punctures in the rows are excessively fine. My 
specimen shows only slight indications of being very sparingly furnished with a 
few short sete, but may possibly be somewhat abraded. 
A single specimen was taken out of a dry twig of Acacia falcata, on Haleakala, Maui, at an elevation 
of about 4000 feet.

HypoTHENEMUS. 
Hypothenemus griseus, n. sp.—Brevis; latior; opacus; pallide brunneus ; 
antennis pedibusque flavis; setulis tenuibus nec brevibus vestitus; prothorace in 
parte anteriori fortiter sparsim rugoso, in parte posteriori subtilissime granulato ; 
elytris creberrime subtiliter punctatis, distincte striatis, interstitiis leviter convexis. 
Long. 2 m.m. 
This species is about the size of the largest H. maculicollis, Sh. Though 
I have carefully examined the antennz under a compound microscope, I cannot 
feel sure whether there are three or four joints in the funiculus. The fine and 
rather long hairlike setze with which it is (not very sparingly) clothed, and 
the sculpture of the elytra—which are rendered opaque by their extremely fine 
punctuation, and are quite deeply striated—separate the insect widely from every 
ally known to me. Its colour is a light umber brown, inclining to grey, which is 
somewhat darker on the thorax. 
A single specimen was taken from the stem of a poppy on the plains near Honolulu, where (and 
elsewhere) the plant grows plentifully ; frequent examination of the stems failed, however, to produce 
the insect again.

Maula (nov. gen.). 
The following are the characters of the insect, apparently allied to Ozotomerus, 
for which I find it necessary to propose the above name :—Head much wider than 
long; rostrum about equal in length and width to the head (the two together 
being scarcely longer than wide), with its sides parallel, and apex very obscurely 
emarginate; rostral scrobes lateral, and consisting of a rounded cavity scarcely
