 By F. Buchanan White, M.D., F.L.S. 



[Eead November 7, 1878.] 



The majority of the insects herein (and probably hereafter) to 

 be described, were taken by my friend Professor J. W. H. Trail 

 during his fruitful exploration of the Amazon region, in 1873- 

 1875 ; and his localities refer to the country drained by that 

 river and its tributaries. The types of all the species men- 

 tioned are in my collection. The subjoined tabular list of two 

 new genera and seventeen new species comprises what is contained 

 in this paper. 



Paryphes pontifex. Velia vivida. 



Fibrenus bullatus. viigata. 



Largus lentus. Neovelia Trailii. 



- Ischnodenaus inambitiosus. Microvelia mimula.
