race transverse trituberculato ; elytris punctato-striatis, singulis 



trifasciculatis. 

 Hab. Aru. 



Oblong-ovate, pitchy, covered with a dense reddish-brown 

 tomentum ; prothorax with three transversely placed tubercles 

 on the middle of its disk ; elytra strongly punctato-striate, the 

 alternate interstices dark brown, with a few white hairs dis- 

 persed in spots, the third interstice from the suture with three 

 dense fascicles of dark-brown hairs ; eyes, mandibles, and an- 

 tennae black, the latter with their joints from the fourth to the 

 eighth white at the apex, the ninth entirely white, except at 

 its apex; legs and beneath brown varied with greyish. Length 

 8 lines. 



The preceding notes having been extended to beyond what 

 was originally contemplated, the species described have been 

 placed without any regard to their natural affinities : there are 

 still, however, many forms, particularly in the extensive private 

 collections of Mr. Wallace, quite as remarkable as any yet pub- 

 lished, besides a number of species referable to genera which I 

 have here sought to establish*.

ON A SPECIES OF EOLIS, AND ALSO A SPECIES OF LOMANOTUS 

 NEW TO SCIENCE ; WITH THE DESCRIPTION OF A SPECIMEN 



OF EOLIS C^SRULEA OF MONTAGU. B WlLLIAM THOMPSON. 



My dredging labours in Weymouth Bay have again been rewarded 

 by the acquisition of two new species of the Nudibranchs, and by 

 the rediscovery of one of Montagu's lost species. This last acquisi- 



* One of these (Nessia) may possibly be synonymous with Dendropemon, 

 Schon., founded on a rare Fabrician insect from Sumatra, which I have 

 not seen.
