142 Buacksurn AND SHARP—On some New Species and Genera of Coleoptera. 
P } 
Fam. CUCUJIDZ. 
BrontoLaMus (nov. gen.). 
Antennz corpore longiores, tenuissimz, articulis, 3-11 inter se subzequalibus. 
Clypeus ante antennas productus, mandibule prorectze, subrectze, basi lato, apice 
acuminato, minute emarginato, vix incurvato. Palpi graciles. Pedes graciles, 
tibiis calecari minuto, recto: tarsi posteriores maris 4-articulati, sed articulo 
basali brevissimo esegre discernendo ; femine 5-articulati articulo basali fere nullo. 
The elegant little insect, for which I propose this generic name, does not appear 
to be at all closely allied to any known genus, but may be best placed near Laemo- 
phleeus, with which it agrees in many characters, but differs in the form of the 
head, the slender legs, antennze, and palpi, and the comparatively elongate little 
curved mandibles. The structure of the antennez is peculiar: the basal joint is 
stout and elongate; the second is rather slender, shorter than any of the others, 
about half as long as the first; the third is subequal to the following joints, each of 
which is very slender, and is slightly swollen at the apex. Each of the three ter- 
minal joints is a little curved, more especially the last one. 
D.S. 
Brontolemus elegans, n. sp.—Subdepressus, opacus, squamulis setiformibus 
depressis parce et irregulariter vestitus, fuscus, antennis pedibusque plus minusve 
dilutioribus; prothorace subcordato, basi elytris angustiore, intra latus linea recta 
subtili; elytris planatis, striatis, versus latera argute carinatis, lateribus perpendicu- 
laribus. Long. 3m.m. (Plate rv., f. 16.) 
Antennz in the female rather longer than the body ; in the male about twice 
as long; head rather narrower than the thorax, with an indistinct reticulate sculp- 
ture, and with fine depressed, pale sete; eyes convex; thorax rounded at the 
sides and narrowed behind, so that it leaves the shoulders of the elytra free ; hind 
angles nearly rectangular, the surface sculptured and clothed like the head, and 
with a fine straight line on each side; scutellum transverse, with declivous front ; 
elytra truncate at the base, prolonged and subacuminate behind, bordered with a 
well-marked carina, extending from the shoulder to near the apex; within this 
carina quite flat, but external to it perpendicular, so that there is a rather large 
lateral portion placed at right angles to the rest of the surface; they are rather 
feebly striate, the striz being evidently marked with punctures; they are quite 
dull, and obscurely maculate, the maculation being due to an irregular distribution 
of the pale scale-like hairs they bear. The slender legs are yellow, more or less 
infuscate. 
A pair of this species has been sent me by Mr. Blackburn as No. 3385. He states that it is a very 
rare insect, but widely distributed, and oecurs both in Oahu and Kauai; it occurs in crevices of the 
bark of living trees, and runs almost like a Longicorn.
