In his " List of British Ilemiptera, &c.," Walker gives Deltoce- 

 2ihnJus vittatus, Linn., citing Germar's figure o£ Jassus vittatus, which, 

 as above indicated, represents C. tindata, Deg., but there is no record 

 of the capture of the latter in Britain until now, although the species 

 is distributed throughout Europe. G. vittata, Linn., is our Eupteryx 

 vittatus.

CONTRIBUTIONS TO A KNOWLEDGE OF THE RHYNCHOTAL 

 FAUNA OF SUMATRA. 



BY W. L. DISTANT. 



The following descriptions refer to species which I have received 

 during the last few years in collections made by Messrs. Forbes and 

 Bock. The collection of Bhyncliota is evidently a pursuit which is by 

 BO means a speciality of those gentlemen, as the small and obscure 

 representatives of the Order are almost entirely unrepresented in their 

 consignments, which have consequently added less, than might have 

 been expected, to our knowledge oE this little-known fauna. Our 

 present information as to the Bhyncliota of Sumatra is greatly due to 

 Snellen van Vollenhoven, whose studies, however, did not extend to 

 the CoreldoB of this island ; to Ellcnricder, w'ho alone treated of the 

 Penlatomidce ; to various descriptions by the late Dr. Stal ; and the 

 same, in a much less satisfactory sense, of the late Mr. Walker. It 

 will be thus seen that, at present, our catalogues and collections of 

 Sumatran Bhyncliota are of the most meagre and superficial character, 

 though we may reasonably hope that this comparative ignorance will 

 soon be greatly modified by the publication of the Natural History
