A single specimen was brought to me at the Selkirk settlements 

 on Red River. I have seen specimens also from Massachusetts, 

 N. Hampshire, Illinois, and Nebraska. 



LocusTARi^ — Latreille. 



Udeopsylla, Scudd. 



This genus is to be placed between Ceuthophilus* Scudd. and 

 Daihinia, Hald. The maxillary palpi are rather long : the first 

 and second joints equal and small ; third more than equal to the 

 preceding together ; fourth little more than half as long as third ; 

 fifth a httle longer than third, somewhat curved, split along the 

 whole under side. As in Ceuthophilus the pro- meso- and meta- 

 nota nearly conceal the epimera of the thoracic segments. Hind 

 femora very heavy, thick and especially broad, but not so much 

 so as in Daihinia, where, as in this genus, the whole limb is 

 swollen, and not the basal portion only, as in the neighboring 

 genera ; it differs from Daihinia in the structure of the tarsal 

 joints, which here have the first and fourth joints equal and long- 

 est, the second and third equal and small, the second overlap- 

 ping the third above. 



Daihinia robusta, Hald. is the type of the genus, a species 

 found in Nebraska. 



U. NIGRA, nov. sp. 



Shining black, with a faintly indicated, narrow, reddish, dorsal 

 line, a reddish tinge on the front of the face, the basal half of the 

 inner surface of hind femora, and the terminal half of the ovipos- 

 itor reddish ; the hind femora of the male have upon either edge 

 of the under surface, but especially on the inner, short but heavy 

 spines, not crowded, the hind tibiae are furnished on either edge 

 of the upper surface with four or five opposite, long and slender 

 spines, between each two of which are placed three or four sup- 

 pressed spines ; there is a single row of short spines upon the 



* Ceuthophilus is a new genus, of which Rhaphidophora maculata, Harr, 

 is the type, for full characteristics of this and Udeopsylla see an article 

 on N. American Orthoptera, presented to the Boston Society of Natural 

 History in May, 1862, and now publishing in their Journal, Vol. VII,
