Specimens of this species are in the collection of the U. S. 

 Nat. Museum, taken on Scirpus sylvalicus at Richfield Springs, 

 N. Y , by Theo. Pergande, No. 4052, and typical specimens on 

 Carex nehraskicnsis collected at Ft Collins, Colo., 5-30-10, by 

 Bragg. These later specimens were deposited in the Museum 

 collection as types by Prof. C. P. Gillette. Oviparous females 

 are in the collection taken on 3-square, Whitesbog, N. J., 11-13-15 

 by H. B. Scammell. 



The species has shorter antennae than the other members of the 

 genus, but is very similar in many ways to americanus and fiabellus. 

 The body hairs are short, stout and spine-like. 



Saltusaphis elongatus, n. sp. 



Only oviparous females of this species have been seen by the 

 writer, but since tliey are so very different from any of the other 

 species in ths genus, no difficulty will be experienced in separating

General colour orange yellow, uniform, with the exception 

 of a number of dusky flecks along the margins of the abdomen. 

 Eyes deep wine colour; antennae, from the basal portion of segment 

 III to the tip, dark brown to black. 



Length from vertex to tip of cauda 2.34 mm.; hind tibiae 0.64 

 mm.; scarcely at all swollen, and covered on its proximal portion 

 with a number of sensoria. These are nothing like as abundant as 

 in the species americanus and virginicus. Antennae as follows:
