Tiipajos; one ^,2 5 individuals; a .specimen was also 

 found at Lages, near Manaos, by Dr. Trail, on the 5th

Ohs. — This species differs from ^S". suitioides by the 

 laroer and more convex eyes, Avhicli reach quite to the 

 back of the head. 



Stenus. 



Although the species of this world-wide distributed 

 genus seem to be everywhere amongst the most numerous 

 of the Stap/ii/linidcc, yet only fourteen or fifteen species 

 have been as yet described from the warmer parts of the 

 New World. The twenty-five s})ecies here described will 

 help, therefore, somewhat to rectify this disproportion, and 

 indicate that the genus is richly represented in South 

 America, as elsewhere. 



Of these species the first eight might, I should have 

 thought, have been properly placed in Erichson's division 

 I. B. Erichson, however, has described three or four 

 species from Columbia (S. augur, &c.), which I judge 

 from his descriptions are very closely allied to these eight 

 species, and has placed them in his division I. A. I have 

 therefore left these s})ecies without indication as to their 

 position in Erichson's classification of the genus. Species 

 12 to 18 belong to a group of which the species are nume- 

 rous in South America, but no species of it occur in 

 Europe. Species 20 — 25 might be placed in a natm'al 

 manner between the European S. cicindeloides and S. con- 

 tractus.
