770 AUSTRALIAN AND TASMANIAN PSELAPHID^, 



joint concealed, second about as long as the width across eyes, 

 basal half thin and apical half dilated, third about half the length 

 of second, the extreme base thin but the rest as thick as tlie 

 dilated part of second, fourth about the length of second, and 

 much the same shape, except that the dilated portion is basal 

 instead of apical. Prothorax strongly convex, wider than long, 

 sides strongly rounded and widest close to apex; with a shallow 

 fovea on each side at base; with fairly distinct punctures. Elytra 

 distinctly wider than long, sides and shoulders strongly rounded; 

 with four small basal fovese; dorsal striae deep at base but ter- 

 minated at basal third; with numerous distinct and, for the 

 family, rather coarse punctures. Melastermim with a strong, 

 subquadrate, apical depression. Abdomen somewhat flattened 

 along middle of undersurface. Legs long; middle trochanters 

 acutely dentate; tibite moderately curved. Length l|^-l^nnn. 



5. DiflFers in having the head without setae, without the strong 

 transverse impression, but with a shallow impression on each 

 side behind base of autennte, and one between them, antenna? 

 somewhat shorter, metasternum less impressed posteriorly, abdo- 

 men not flattened along middle, and legs shorter, with the middle 

 trochanters unarmed and the tibite less curved.

 places under rotting leaves), Sydney, Otford{A. M. Lea), National 

 Park(H. J. Carter). 



The head conspicuously transversely impressed distinguishes 

 from R. subulatus, and metasternum impnnctatein middle instead 

 of with comparatively coarse punctures;* the general punctures 

 are also smaller, although still conspicuous, and the palpi are 

 rather stouter. In some respects close to the description of H. 

 coniiger, hut head without "two thick setae projecting like horns 

 from between the antenna?." Raffray described the head of li. 

 pjrcellus (the species he supposed to be E. coruiger) as bearing 

 *' two strong and short brushes of yellow hairs." 



* A character omitted from the original description, but of which I can 

 be certain, having a cotype from Dunheved.
