418 Rev. H. Clark's Descriptions of new 



have, by the kind liberality of Mr. Arthur Adams, received a 

 series both from the Corea and from Canton. 

 Mr. Bowring has taken it near Amoy.

Ovatus, apicfe attenuatus, nigro-punctatus, pallide testaceus, 

 linea a capite ad apicem lata mediS, inaequali, maculisque 

 minutis ad elytra nigris ; capite sparsim punctato, ad basin 

 antennarum transversa foveolato, rufovel rufo-fusco; thorace 

 lateribus obliquis subrotundatis, basi sinuato, punctato, me- 

 dio vitta subtriangulari nigra ; elytris punctis sat parvis nigris 

 ordine dispositis, basi media vittaque suturali, maculisque 

 undique minutis parvis nigris, vitta ante medium iterumque 

 post medium latiori ; corpore subtus pallide flavo, pedibus 

 antennisque rufis.

The medial longitudinal marking, which so strikingly designates 

 this species, slightly varies in form ; in all examples before me it 

 is broader near the middle, and also near the apex, differing some- 

 what in outline and in breadth. 



Mr. Bowring has received two specimens from Siam, and Mr. 

 Wallace has taken the species near Malacca. 



3. //. eximius, n. sp. 



Elongato-ovalis, sat convexus, ad apicem acuminatus, striato- 

 punciatus, rufus; capite infra antennarum basin transverse 

 depresso, leviter punctato ; thorace antice emarginato, lateri- 

 bus rectis, obliquis, basi sinuato fortiter sed sparsim punctato, 

 elytris elongatis, striato-9-punctatis, interstitiis etiam leviter 

 striato-punctatis, corpore subtus rufo-fusco, pedibus antennis- 

 que rufis.

In form and colour generally H. eximius much resembles H. 

 ruhidus, Perris {■== perforalus, Schaum), from the Pyrenees; the 

 thorax of the species before us is broader at the base, more con- 

 tracted towards the front, and less closely punctate ; the elytra 

 are the same in form (a trifle narrower and more acuminated); the 

 interstices between the rows of punctures have each of them a 

 row of similarly arranged but smaller punctures (the similar in- 

 terstitial punctures in H. ruhidus being more interrupted). 



Two examples of this species were taken in a pond on Deer
