486 ON AUSTRALIAN ANTHICIDAE^ 



base there is a distinct subtubercular elevation, which is much more feeble on the 

 type, the legs are also darker than on the type. 



Anthicus electilis, n.sp. 



iS. Flavous, elytra (except basal fourth) and abdomen black, head slightly 

 infuscated. Elytra sparsely pubescent and with a few hairs, but with a con- 

 spicuous band of silvery pubescence where the two colours meet. 



Head subglobular, hind angles and base completely rounded off; densely 

 granulate-punctate between eyes, punctate only at base. Eyes large and medio- 

 lateral. Prothorax distinctly longer than wide, distinctly narrower than head, 

 apical two-thirds with strongly rounded sides, strongly notched near base, with a 

 rather wide depression connecting the notches, median line distinct near apex, 

 and again near base; punctures sparse and inconspicuous. Elytra much wider 

 than prothorax, shoulders gently rounded and oblique inwardly, sides moderately 

 inflated to beyond the middle, with a conspicuous transverse depression near 

 base, on each side of base a prominent subtubercular elevation; punctures sparse 

 and inconspicuous. Intereoxal process of abdomen briefly triangular. Leg's 

 rather long, hind femora subclavate, hind tibiae distinctly longer and somewhat 

 thicker than the middle ones, front tibiae slightly dilated on under surface to 

 apical third, and then more strongly narrowed to apex. Length, 2.75 mm. 



Hob. — Northern Queensland (Blackburn's collection). 



As the femora are stout, but less conspicuously clavate than is usual in 

 Formicomus, the body winged, and the intereoxal process of abdomen somewhat 

 triangular, it seems desirable to refer the species to Anthicus rather than to 

 Formicomus; it appears to connect the former genus (by way of the A. unifas- 

 ciatiis group) with the latter (by way of the F. agilis group). The colours of 

 the type are somewhat as on the type of the preceding species, but the head is 

 larger, more globular, the inter-antennary space very different, eyes much larger, 

 prothorax longer, elytra more dilated, and hind tibiae much longer and thinner 

 (although stouter than on many species of the genus). The subtubercular ele- 

 vations at the base of the elytra are quite distinct from above, and very con- 

 spicuous from the sides. The two basal joints of the antennae are flavous, the 

 others are missing from the type. 



A female (from Cairns) evidently belonging to this species, differs from the 

 type in having the upper surface black, except that the bases of the prothorax 

 and of elytra are very obscurely diluted with red, but the band of silvery 

 pubescence is quite as distinct; its legs are blackish, with the coxae, tarsi and 

 part of the middle tibiae flavovis, and the base of the middle femora almost 

 white; its hind legs are somewhat shorter, and front tibiae not dilated near 

 apex; its antennae are long, with the three apical joints black and wider than 

 the others (so that they appear to have a loose, three-jointed club), the tip of 

 the eighth joint and the base of the first are also infuscated. 



Anthicus bilobiceps, n.sp. 



Keddish-castaneous, legs somewhat paler, elytra blackish, the apex and a 

 large spot on each shoulder reddish. Elytra with rather dense and short, pale 

 pubescence, rest of upper surface sparsely clothed. 



Head subovate, sides behind eyes parallel to near base, hind angles moderate- 

 ly rounded, base distinctly bilobed; with rather dense punctures, of moderate size 

 and shai'ply defined. Eyes of moderate size, not extending half-way to base. 

 Antennae rather long and thin, none of the joints transverse. Prothorax dis- 

 tinctly longer than wide, slightly narrower than head, decidedly convex, sides
