THE CANADIAN ENTOMOLOGIST. 



male valve small, not as long as the. ultimate segment, roundingly 

 triangular; plates narrow, long, triangular, their apices acute. 



Described from ten specimens from Rifle, Dolores and Durango, 

 Colo. The white margins anteriorly and the sharply defined tip to the 

 elytra against the rich ground colour render this an easily recognized 

 species. The general shape and colour suggest the genus Platymetopius, 

 but the shorter vertex and the face characters place it with Scaphoideus. 

 Such species as this weaken generic characters and at the same time 

 help us in that they show affinities. 



Phlepsius Vanduzei, n. sp. 



Form and general appearance of cinerens, but much larger ; stouter 

 built than even nebidosus; grayish cinereous, with a trilobate commissural 

 line. Length, 8 mm. ; width, 2.75 mm. 



Vertex very bluntly conical, one-fourth longer on middle than against 

 eye, three-fifths the length of the pronotum, no visible line between it and 

 front ; front not quite as long as its basal width, the apex one-third the 

 width at base ; clypeus long, wedge-shaped, broadest below ; pronotum 

 two and one-third times wider than long. Elytra broad, longer than the 

 body, compressed before the flaring apex ; claval veins sometimes tied 

 across. 



Colour : dirty white, sometimes a pale yellow wash on vertex and 

 pronotum. Vertex with a distinct round black spot on the middle of 

 either side at the base, a few irregular dark vermiculations anteriorly, 

 omitting a broad median line which extends down the front ; numerous 

 short arcs on front, a spot on clypeus, a pair on lor*, another pair just 

 under eyes, fuscous. Pronotum and scutellum with very faint markings, 

 elytral veins yellow and fuscous ; between them the membrane is very 

 finely, sparsely, and somewhat irregularly vermiculate, omitting a broad 

 commissural line, which is divided into three lobes by the apices of the 

 claval nerves. The outer apical and two costal veins often very much 

 infuscated, the spaces between clear. 



Genitalia : ultimate ventral segment of the female appearing only as 

 a narrow strip along the pleura on either side ; in its place is a thin mem- 

 brane shaped almost like the segment in apertus, with its rectangular 

 median excavation, and showing beyond its posterior margin the rounded 

 apices of the plates, near the middle line, and the rounding lobes of a 

 second membrane near the lateral angles ; male valve triangular, the apex 

 bluntly roundingly produced ; plates broad at base, roundingly triangular,
