470 Mr. A. M. Lea on 



of coxse to their extreme depth, as in other Cryptorhynchides, 

 but the mesosternum has no special receptacle for the 

 rostrum, this simply resting in the hollowed-out space (as in 

 Micruberosiria and Di/stropicus). In Aonyclms (the only 

 other Australian genus of Cryptorhynchides with clawless 

 tarsi) there is a narrow ridge bet-iveen the middle coxae, that 

 genus also has special processes attached to the hind portion 

 of the presternum. In catalogue the genus should be placed 

 next to Dystropicus. 



The genus is another instance of the decided affinity of 

 the Cryptorhynchides to the Erirhinides, Several Australian 

 genera {Cydmaa, Storeus, and Misojjhrice) have species with 

 the front coxte not quite touching and with more or less 

 feeble traces of a pectoral canal ; but in the present genus 

 the canal is deep and distinct, so that it could not properly 

 be referred to the Erirhinides. 



The joints of the antennse are evidently eleven in number, 

 but it is somewhat difficult to decide as to whether the eighth 

 joint should be regai'ded as belonging to the funicle or to 

 the club. It is more triangular in shape than the seventh 

 (the sixth of the funicle) and rather closely applied to the 

 club, its clothing causing it to appear more closely attached 

 than it really is. The three true joints of the club, however, 

 are compacted together, so it would, perhaps, be as well to 

 regard the eighth joint as belonging to the funicle and the 

 latter, in consequence, to be seven-jointed. 



The clawless tarsi, apparently six-jointed funicle, general 

 appearance, and food^plauts (most of the specimens, if not 

 all, taken by myself were beaten from various species of 

 Casuarina, the host-plants of Misophrice) are in agreement 

 with Misophrice^ and, in fact, caused me to overlook such of 

 the species as I then possessed when at work on the group 

 of Cryptorhynchides to which they belong ; and it was only 

 when preparing some specimens of Misophrice for description 

 that their true relationship was noticed. 



Only three specimens, belonging to two species, were 

 taken by Mr. Bryant, but, as the genus is a very interesting 

 one, it appears desirable to describe all the species known to 

 me together. 



All the known species have the rostrum glabrous and the 

 antennae (except the scape) and tarsi black. The genus 

 occurs in South Australia, but the only specimen I have seen 

 from that State (in the collection of Mr, Griffith) is rather 

 badly abraded.
