HORN EXPEDITION—COLEOPTERA. 
to found a new genus for it. It is so densely covered with closely adpressed small 
scales that the derm is invisible except by abrasion. Regarding the whitish scales 
as forming the ground colour, the smoky blackish scales form three vitta) and some 
minute spots on the prothorax, and on the elytra a pattern of irregular zig-zag 
transverse lines consisting of small mostly confluent spots, the scutellum and 
hinder half of the suture being also clothed with smoky blackish scales. The 
scales of the head, legs, and under surface are almost entirely whitish, with a 
tendency to a greenish tone in places.

BELUS. 
B. anguimus^ Pasc. ? (1), Camp 4. I take this insect to be a variety of a 
species I have myself taken in southern Central Australia and which I have, not 
without some uncertainty, referred to migumeiis. 
TENTEGIA.

gineis; squamositate ferruginea in partibus depressis vestita ; capite (hoc lequali) 
rostroque grosse punctulato-ruguloso, hoc fortiter 5-carinato ; prothorace ut caput

ante medium dilatato-rotundatis, postice rectis convergentibus; elytris ad basin

humeros rotundatim dilatatis, humeris antrorsum sat prominulis; femoribus ut 
caput punctulato-rugulosis, subtus ante apicem dente minute instructis ; tarsorum

The small but distinct tooth on the underside of the femora seems to be little 
more than the angle formed by the presence of a deep and abrupt emargination 
on the lower face of the segment immediately before its apex. It is most 
conspicuous when the front face of the femur is looked at from such a position as 
to display the outline of the lower surface. The presence of this tooth distinguishes 
T. Spenceri from T. favosa, Pasc., and T. Sana, Faust, while the absence from the 
forehead of a longitudinal sulcus and from the rostrum of a fovea between the bases
