macularis. How this may be 1 cannot say, but it must be noted 

 thai my specimens have the eyes short-haired, but more distinctly 

 haired than punctulatus, and the antennæ shghtly pale beneath the 

 third joint. I have placed the species here because of the hairy eyes, 

 but the short eye-hairs and somewhat dark epistoma show that it 

 has affinities to punctulatus and its allies.

Male. Vertex black, ralher elongate; frons yellow pruinose but 

 black above the antennæ. Epistoma yellow, somewhat pruinose, but 

 shining; it has a broad, black middle stripe, attenuating up towards 

 the antennæ; the mouth edge and lower hind corners black; jowls 

 grey pruinose. Vertex and frons black-haired, epistoma with rather

 yellowish grey pruinose, it is very narrow above and concealed by 

 the eyes; the hairs white below, yellow upwards; above a row of 

 black, overhanging hairs. Eyes with somewhat short, pale hairs. 

 Antennæ black, third joint about as long as the two basal together; 

 arista about as long as the antennæ, brown at the base. Thorax 

 dark or blackish æneous, somewhat shining; it is clothed with dense, 

 yellow hairs, more or less intermingled with black, the latter tending

 the side margin; the basal spots large, transverse, sloping upwards 

 towards the sides ; the band on third segment placed a little Irom the 

 fiont margin, sloping at the sides and more or less deeply emarginate 

 in the middle of the hind margin, the band on fourth segment of the 

 same shape but nearer the fi-ont margin; fourth and fifth segments 

 with orange hind margins and the latter also with front and side 

 margins pale. The hairs somewhat long, chiefly foUowing the ground 

 colour, but mainly pale at the base and between the basal spots; at 

 llie sides the hairs are yellow, at the base mixed with black, for the
