pale parts is somewhat stramineous; on the dark parts, it is darker. 

 In this and the following species, the hind coxa; at the sides are 

 a trifle longer than the second abdominal segment; in the pre- 

 ceding species, they are of exactly the same length. 



ArISOCEPHALUS BASALIS, n.sp. 



Black; basal fifth of elytra reddish, tibia? reddish, femora and 

 coxie darker, tarsi paler, antennae dull reddish-brown, second and 

 third joints and the tips paler. Clothed with very short and 

 mostly stramineous pubescence. 



Head with crowded and rather small punctures; with a con- 

 spicuous median carina from base to apex, an oblique carina on 

 each side of clypeus from apex to base, where they almost touch 

 the median line between the antennary sockets. Antennae not 

 very long, second joint short but distinctly longer than third, 

 the two combined slightly loijger than fourth, fourth-tenth equal 

 in length, but decreasing in width from the sixth, and rather 

 feebly serrated, eleventh about once and one-half the length of 

 tenth. Prothorax much as in A. Jfavipes except that the punc- 

 tures are smaller. Elytra parallel-sided to about the middle; 

 with rather dense, well-defined punctures, becoming crowded at 

 base; striation fairly well defined. Abdomen with fifth segment 

 somewhat produced at apex, and densely granulate-punctate 

 there. Length, 3J mm. 



^a6.— N.S.W.: Galston (A. M. Lea); unique. 



The third joint of the antenna?, although very short, is not 

 " excessively minute " as in Entomophthahnus; and the fourth 

 joint, although somewhat larger than the fifth, is scarcely longer. 

 The carination of the head is more pronounced than in the other 

 species of the genus, and is much as on Arisus carinatice2ys. 



Fornax nicer, n.sp. 



Black. Clothed with short, depressed pubescence, paler about 

 base of prothorax and of elytra than elsewhere. 



Head with crowded subasperate punctures; with a feeble longi- 

 tudinal carina, and a conspicuous interocular one. Antennae 

 moderately long, first joint about as long as three following com- 

 bined, second shorter than third, and third than fourth, fourth-
