746 AUSTRALIAN AND TASMANIAN PSELAPHIDiE 



large fovea on each side neai* base, and a small one in middle. 

 Elytra not much wider than long, dorsal strise finely impressed 

 to just beyond the middle, and then vanishing; marginal stria 

 deep, but epipleural furrow absent. Undersurface of abdomen 

 with two conspicuous parallel ridges extending to apex of second 

 segment, third and fourth not traceable across middle, Meta- 

 sternum strongly concave in middle, the concavity bounded be- 

 hind by a thin intercoxal lamina; with a small fovea close to 

 each of the middle coxse. Tibice rather long, especially the hind 

 pair, which are also rather strongly curved at apex. Length If 

 mm. 



Hab. — N, S. Wales: Illawarra, Grose Valley, Blue Mountains;^ 

 a single male from each locality(H. J. Carter). 



The enormous head(in the female it is probably smaller) readily 

 distinguishes it from all other species of the genus(or indeed of the 

 family) known to me. The medio-basal fovea of the prothorax is 

 not connected with the sides, although there is an impression on 

 each side which almost touches it and the lateral ones; the 

 species therefore belongs to M. Raffray's second group of the 

 genus, although he would possibly regard it as representing a 



new genus. 



The interocular fovese are smaller and more distant from the 

 eyes than usual; from some directions they appear to be closed,, 

 but from others a vague depression can be seen opening out in 

 front from each of them. The antennae appear to have the club 

 one-jointed, as the tenth joint, although decidedly longer and 

 wider than the ninth, is very much smaller than the eleventh. 

 There are fairly numerous punctures on the elytra, but they are 

 much less distinct than those on the prothorax. 



The males of the species here described may be tabulated as^ 

 follows : — 



A. Foveae of prothorax disconnected. 

 a. Abdomen with two conspicuous parallel ridges on 



undersurface macrocephala. 



aa. Abdomen without such ridges. 



b. Metasternum with two depressed tubercles over- 

 hanging coxae aleatoria. 



bb. Metasternum without tubercles pallida^
