220 NATURAL History BULLETIN. 
The Clavigeride live seemingly solitary; the construction 
and smallness of the oral organs seem to indicate that their 
nourishment is taken in liquid form. 
Of the larve nothing is known, our own investigations 
yielding doubtful results. 
l. CLAVIGERIDA. 
Antenne and tarsi two-jointed, anterior cox contiguous, 
posterior ones distant. Two genera are represented in our 
fauna: 
Eves wanting. a pins - . Adranes, Lec. 
Eyes present. - - - -  Articerus, Dahim. 
ADRANES (from ddpavyc, imbecile). 
Prothorax, when viewed from above, conical; head 
cylindrical. Length, 1.8 mm. - - Cecus. 
Prothorax campanulate; head obconical. Length 2.5 
mm. - - - - - - lecontet. 
A. ca@cus, Lec. Orange yellow, pubescence in regular 
rows of short, recumbent sete. Length, 1.8 mm. Plate I., 
Figs. 4 and 5. 
flead variolate, frontal margin straight, antennal fovez 
large, extehding to the middle of the clypeus and leaving a 
narrow septum connecting the frontal margin with the labium. 
The last antennal joint is rounded at the base, longer than one- 
half the length of the head, squarely truncate and narrower at 
the distal end. Palpi small, hidden inside of the circular oral 
opening. Prothorax as long as wide near the base, where 
the width equals the length of the head, neck half as wide as 
the base. Sides, at base, rounded, arcuate, straight towards 
the neck. Disk variolate, with a deep median sub-basal, cir- 
cular fovea. /ytra with the suture as long as the prothorax, 
which they very slightly exceed in width at base, middle 
depressed, sides straight, divergent, longer than the suture, 
posterior margin of each elytron triangularly lobed; disk 
without impressed lines, apex of lobe tufted with hairs.
