Appendix, by John L. LeConte, M.D. 



Tachyporus JOCOSUS Say; arduus Er. 



A variety of this species, nearly black, with the prothorax dark 

 brown towards the sides, was collected by Mr. Austin, The pubes- 

 cence of the elytra and dorsal surface of the abdomen is unusually 

 well preserved, and quite sericeous. 



Dianous nitidulus sp. nov. 



Black, shining, with a bluish lustre, strongly but sparsely punctured ; 

 prothorax one half longer than wide, widest before the middle, where 

 it is rounded on the sides; disc with two vague transverse impres- 

 sions, one near the tip, the other behind the middle ; elytra as wide 

 as the head, a little longer than wide, convex, with a small, oval, yel- 

 low spot just behind the middle, and nearer the side than the suture; 

 abdomen strongly margined, finely punctured, with two long anal fil- 

 aments at tip. Length, 4.7 mm. ; .18 inch. 



White Mountains, Oregon and British Columbia. 



Remarkably different from D. ccerulescens and chalybceus by the 

 punctuation being deep and sparse, as in Stenus kiesenwetteri of Eu- 

 rope. Otherwise it resembles D. chalybceus, but is more slender. 



In the 6 the sixth ventral segment is broadly and strongly emargin- 

 ate.
