Recent Observations on Plagithmysus Spp. and Nesotocus 

 Munroi at Kilauea Hawaii (Coleoptera). 



(Witli cxhil)ition of specimens) 

 BY W. M. GIFFARD. 



Numerous specimens of Plai:;ithiiiystis and of Xcsotocus 

 munroi were recently collected by the writer during a short 

 summer visit to some of the forest regions at Kilauea, Hawaii. 

 These regions were all within a radius of approximately two 

 and a half miles of the Volcano House, and included areas in 

 the dry, intermediate, and wet forests. In addition are shown 

 several single specimens taken at large and otherwise on pre- 

 vious visits to Kilauea. 



Examples of all but the commonest of these will be sent 

 to Dr. R. C. L. Perkins for final determination of the species 

 so that they may, if possible, be added to our reference collec- 

 tions. The exhibit included the following species :
