160 Mr. G. C. Champion’s Notes on 
the eyes enormously developed; antennae with joints 4-10 each 
furnished with a long ramus, that on joint 4 much shorter than that 
on 5, joint 3 acutely, triangularly dilated. Thorax transverse, very 
broad, compressed at the sides anteriorly, obliquely narrowed (as 
seen from above) forwards; densely, rugulosely punctate, the sinuous 
depressions on each side of the disc interrupting the arrangement of 
the pubescence. Scutellum ratherlarge. Elytra distinctly narrower 
than the thorax, finely, interruptedly, subseriato-punctate, the 
interstices rugulose; with a transverse depression on the disc below 
the base and various other rounded depressions on the apical half, 
interrupting the arrangement of the pubescence. Legs moderately 
elongate, the tarsi shorter than the tibiae. 
Length 4, breadth 14 mm.

Gorham suggested that this species was probably a 
known N.-American form, on what grounds I know not. 
The enormously developed eyes, the very broad thorax, 
with a sharply defined darker median vitta, and the uneven 
elytra are characteristic. The unique example is some- 
what immature, and the elytral depressions may be in part 
due to the softness of the integument, but as they are 
symmetrical, this is not likely to be the case. 
*Ptilinus maculicollis, n. sp. (Plate IV, fig. 9, 3.) 
dg. Elongate, narrow, cylindrical, opaque, black, the thorax with a 
large rufous patch on each side extending forwards to the anterior 
angles ; closely, very finely pubescent. Head broad, densely, rugulosely 
punctate, the eyes large; antennae with joints 3-10 each furnished 
with a moderately long ramus, the rami becoming gradually longer 
outwards, that on joint 10 nearly twice as long as that on joint 3. 
Thorax transverse, compressed at the sides anteriorly, obliquely 
narrowed (as seen from above) from about the middle to the apex, 
the sides and base sharply margined, the hind angles rounded, the 
anterior angles sharp and reaching to the middle of the eyes (when 
the head is in a vertical position); densely, rugulosely punctate, 
subgranulate on the disc towards the apex, the disc feebly canalicu- 
late. Scutellum small. Elytra elongate, of the same width as the 
base of the thorax; regularly punctate-striate, the interstices narrow, 
feebly convex, and densely rugulose. Legs elongate, the tarsi fully 
as long as the tibiae. 
Length 3, breadth 1 mm.
