148 | BiackBuRN AND SuHarp—On some New Species and Cenera of Coleoptera. 
female sex, and have the antenne short, the club three-jointed, and in length 
equal to the five or six preceding joints together ; the apical joint but little longer 
than the tenth; thorax densely pubescent, so that its punctuation is concealed; the 
pubescence pale, but in certain lights appearing dark on the middle parts, owing 
apparently to an admixture of spots or patches of black pubescence; elytra not 
quite so densely pubescent as the thorax ; the pubescence black, but there is a con- 
spicuous band of cinereous pubescence near the base, which at the suture is 
strongly angulated in front, so as to approach rather near to the scutellum ; legs 
entirely red. 
Found in the houses of Honolulu. Sent as No. 427. 
LABROCERUS (noy. gen. ). 
Antennz eleven-jointed, scarcely clavate, in the male with elongate terminal 
joint, hirsute, conspicuously and peculiarly so in the male; prosternum rather 
short, not at all directed upwards, but rather slightly deflexed in front in 
the middle, so as to form a protection for the parts of the mouth which 
are covered by it, except the labrum, which is completely exposed; antennal 
fossee not present; prosternal process rather broad and flat, received into the 
mesosternum ; middle coxe but little separated; hind coxal lamina of moderate 
size. ; 
This genus is allied to Attagenus and Perimegatoma, but with a quite different 
structure of prosternum from the former, and possessing probably a much shorter 
prosternum than the latter genus. It is possible, indeed, that Perimegatoma is but 
a synonym of Megatoma, this European genus having been stated by error in 
Lacordaire to possess antennal fosse. From Megatoma Labrocerus is, I think, 
certainly distinct by its prosternal structure, the prosternum being but short and 
little rounded in front, the prosternal process more developed, and the mesosternal 
fossa extending quite to the metasternum: as in Megatoma, the sides of the pro- 
sternum are concave, but there is no true antennal fossa. 
DNS: 
Labrocerus jaynei, n. sp.—Suboblongus, parum convexus, niger, haud dense 
pubescens, antennarum basi sordide testaceio, elytris maculis quatuor fulvis, duabus 
anterioribus fere in fasciam curvatam conjunctis. Long. 34 m.m. 
Antennz in the male as long as the head and thorax; second joint quite short, 
subglobular; third quite small and rather closely connected with the fourth; this 
latter and the two following joints somewhat short, and a little produced and 
acuminate inwardly; joints seven to ten rather broader, each very strongly trans- 
verse ; terminal joint as long as the five preceding together. In the female the an- 
tenn are about as long as the head; the third joint is slender and rather elongate,
