last dorsal is also sinuate at apex and is acutely elevated near the 

 middle of the disk — generally a female character in Batrisus and 

 Arthmius, although common to both male and female in Batrisus 

 denticauda. The stomata of the last dorsal form round perforate 

 and conspicuous foveas at the extreme lateral angles of the disk ; 

 they are also visible at the sides of the disk on the penultimate seg- 

 ment. Raffrayi differs greatly from the Mexican dispar Shp. in 

 the relative proportions of the antennal joints, and especially in the 

 shorter eighth joint ; it also differs in the narrower form of the body 

 and uniform dull brownish-ferruginous color. It is presumably 

 identical with the form referred to by Dr. Brendel (Tr. Am. Ent. 

 Soc, XX, p. 282), as having been recently taken by Mr. Bolter in 

 Arizona. 



I take pleasure in dedicating this species to Mr. Achille Raffray, 

 whose excellent work is doing so much to advance our knowledge 

 of these fascinating little organisms. The plates recently published 

 by Mr. Raffray, which appear to be simple reproductions of pencil 

 drawings by photo-mechanical processes, were never surpassed by 

 lithographer or engraver, and are doubtless as true to nature as 

 they are beautiful in execution. 



In the following synonymical list of the Pselaphidse thus far 

 described from America north of Mexico, the arrangement of Mr. 

 Raffray is adhered to throughout, except where modified in the pre- 

 ceding notes : —
