128  Biacksurn and SHarP—On some New Species and Genera of Coleoptera. 
Sericoderus pubipennis, n. sp.—Suboblongus, testaceo-ferrugineus, antennis 
pedibusque testaceis, illarum clava fusca; elytris subtiliter punctatis, longius 
conspicue pubescentibus. Long. 1 m.m. 
Antenne pale yellow, but with the rather large club abruptly infuscate. 
Thorax sparingly pubescent. Elytra rather sparingly punctate, so that their sur- 
face is shining, but this is much concealed by their conspicuous comparatively 
elongate pubescence. 
The species is very like 8. lateralis, but the more sparing punctuation and more 
conspicuous pubescence leave no doubt it is distinct. Dr. Horn informs me that 
it differs also from the North American species. 
The type was captured at an elevation of about 4000 feet on the mountains of Maui and sent me as 
No. 419. A second specimen, found on the mountains of Oahu, and sent as No. 865, appears to be 
immature, and has the antennal club scarcely infuscate. 
Das: 
ORTHOPERUS. 
Orthoperus eequalis, n. sp.—Minutissimus, anguste ovalis, convexus, sat nitidus, 
fuscus, antennarum basi pedibusque testaceis, elytris crebre subtilissime punctu- 
latis. Long. 3 m.m. 
This atom is similar to O. atomus, Gyll., but is narrower and has a closer 
punctuation on the elytra, which are less shining. This character distinguishes 
it also, Dr. Horn informs me, from the North American species. The basal 
portion of the antenna is clear yellow, the club infuscate. 
Beaten from dead wood on Mauna Loa, Hawaii. 
Fam. HISTERIDA. 
Bacanivus. 
Bacanius atomarius, n. sp.—Breviter ovalis, convexus, ferrugineus, sat crebre 
et fortiter punctatus ; mesosterno breve, punctato. Long. 1 m.m. 
Thorax very distinctly though rather finely punctate, with basal transverse 
series of punctures. Elytra rather coarsely punctate, the punctures on the apical 
portion finer and very dense, some distance internal to the shoulder are the 
rudiments of two very indistinct short oblique strie. Pygidium much inflexed, 
rather closely punctate. Under surface rather coarsely punctate, except on the 
middle of the breast.
