T.ill I Hypera and Phytonomus in America 431 



most of the thoracic hairs are more or less decumbent, curved backward, 

 especially on the prothorax and near the base of the elytra. Alternate 

 interspaces often tesselated with dark brown, especially on the sides 

 Hairs on interspaces white, except for an occasional black one, humeral 

 spot very large and distinct, brownish-gray or even black or parti- 

 colored, this spot extending back on the interspaces for a considerable 

 distance; a dark common central basal elytral spot is present 



Venter with scales of under side of thorax shorter and wider, on the 

 abdomen some are arranged in transverse rows at the posterior margins 

 of the segments; mesosternal process between the middle coxa? elevated, 

 curved backward, narrowly elongate and ending in a sharp point; a 

 short triangularly produced process from the presternum is also evident 

 between the front cox;e; intcrcoxal process of first abdominal segment 

 rounded broadly to a point. 



Legs vary from black to reddish-brown, all the femora darker than 

 tibiae and covered with long narrow emarginate scales, the points of 

 which are very long and slender; crown of spines on anterior tibiae yellow 

 and blunt ;tilvi;c and tarsi hairy, first three joints extremely setose 

 beneath with silvery hairs; front femora of the male not strongly curved. 



The declivity of the elytra in this species is very evident as will be 

 seen from the illustration, but not as great as in P. maritinius, where it 

 extends quite to the tip. 



Distribution: Type locality for trivittatus; "North-west 

 Territory," and for setigerus: "Kansas." The type specimens 

 of setigerus are in the Leconte coll. in Mus. Comp. Zoology, 

 type no. 398; there are two specimens marked type. 



Dominion of Canada: Manitoba: Aweme, iv— 23-10 (E.

 this specimen in 1X97, I have not seen it.

The Ft. McLeod record is possibly from one of the specimens 

 reported by Evans (1903) as collected by John MacCoun in 

 "Northwest Territory of Canada." Through Dr. Hewitt, Mr. 

 T. D. Evans has loaned one specimen which is labeled 

 "N. W. T. Can. J. M. 1879."
