 becoming obsolete near sides. Intervals finely rugulosely punc-

I captured a considerable number of this small Pterohelaeus in 

 September, 1907, on the underside of a dead tree, in the crevices 

 of which they were so well concealed by their colouring as to be 

 difficult to detect. Its nearest ally in colour and facies is P. 

 thymeloides Pasc, from South Australia, which is, however, a 

 much larger and more convex insect (among other differences). 

 The only other Pterohelseus known to me of such minute dimen- 

 sions is P. opatroides Macl., which is black in colour, longer and 

 narrower than the above, with a widely different sculpture. The 

 strongly clubbed antennas in conjunction with its small size 

 should enable this species to be easily identified. 



Chartopteryx imperialis, n.sp. (Subfamily Cyphaleince). 



Elliptical-elongate, glabrous, subnitid, chocolate-brown above, 

 darker beneath, tibiae and basal joints of antennae red. 



Head : labrum emarginate, hairy, truncate in front, widely 

 rounded on sides; epistoma prominent, raised and punctate, 

 sinuate in front, meeting the square antennal orbit at right 

 angles. Eyes very large, coarsely faceted and separated by about 

 one-half width of one eye. Front more finely punctate than 

 epistoma. Antennae long, extending beyond base of prothorax, 

 first joint stout, second thinner and very short, third as long as 

 fourth and fifth combined. Joints 4-7 of equal length; 8, 9, 10 

 shorter and thicker; 11 about as long as 9 and 10 together. 

 Joints 1-7 red and smooth, 8-11 brown and hairy. Prothorax 

 almost flat, 6 x 10*5 mm., the length (excluding front angles) 

 being measured at middle, the width at base. Width at apex 

 6 mm. Truncate in front, except for prominent and wide front 

 angles, these acute, slightly reflexed, and extending the full 

 length of the eyes. Sides very gently rounded, and slightly 

 produced backwards at posterior angles, the latter acute. Base
