P. nothus from P. Lindl, The elytra of P. Icsvis are devoid of 

 distinct puncturation. Dr. Sharp has favored me with the in- 

 formation that P. Lindi bears close specific resemblance to 

 Clieiroplaiijs Fischer i, Montrouzier (from New Caledonia), but 

 it is, no doubt, distinct from that insect, being certainl}- not a 

 Cheiroplatys. 



I have specimens from Port Lincoln, Fowler's Bay, and 

 'Ouldea ; that from the last-named locality was collected by 

 Professor Tate. An imticketed female in the South Austra- 

 lian Museum has the clypeal suture a little strongly developed, 

 but does not differ otherwise from the type. 



PniELOPTJS. 



As I have said above, I have no doubt that Pimelopus 

 jiorceUics, Er., is congeneric (not as Dr. Burmeister supposed 

 with his P. nothus, but) with certain forms of Bynastidce in 

 which the hind and intermediate tibiae are strongly bicarinate 

 transversely, and their tarsi very short with the basal joint 

 extremel}^ compressed and dilated, while the male has merely 

 a small tubercle on the head and the prothorax quite simple. 

 In all of them known to me the prothorax has a well defined 

 impression at the base on either side. The first species 

 described below may be P. porcellus, Er. It agrees fairly well 

 with the rather brief description, but if it be identical probably 

 Erichsen was in error in regarding the type as a female. In 

 .any case a full description will be useful. 



P. porcellus, Er. (?) Oblongus Nigro-brunneus, capite obscure 



rugato ; prothorace hand evidenter punctulato ; elytris 



fortiter crasse punctulatis, disco fortiter striatis. Long. 



9 1. ; lat. 4i 1. 



Mas. Capite tuberculato ; tibiis anticis minus dilatatis externe 



leviter vel vix tridentatis. 

 Eem. Capite vix subtuberculato ; tibiis anticis obtuse triden- 

 tatis. 

 The clypeus is not distinctly bidentate in front, and its 

 margins are hardly reflexed ; its suture is scarcely traceable, 

 tind in the male is furnished in the middle with a large, but 

 -only slightly raised, tubercle. The prothorax is not quite half 

 again as wide as long, its base nearly twice as wide as its front 

 margin, which is only slightly concave ; its sides are rather 

 strongly rounded and it is widest behind the middle ; under a 

 very strong lens its surface is seen to be minutely and closely 

 coriaceous ; it is margined in front and at the sides ; its anterior 

 angles are acute, the hind angles almost rounded off ; its base 

 is distinctly bisinuate. The scutellum is large and impunctate. 

 The elytra are considerably wider than the prothorax and are
