FOUR NEW SPECIES OF PLATYMETOPIUS. 



BY C. F. BAKER, ST. I, GUIS, MO. 



Platyvietopius ornatjis^ n. sp. 



Length, $ , 5.25 mm., of which the head occupies i mm.; width 

 across base of elytra a little more than i mm. Vertex rather strongly 

 obtusely angulate ; width between eyes three-fourths the length at middle, 

 which is more than twice length at eyes ; the disc is evenly slightly 

 convex. Face, viewed from the side, straight. Pronolal width two and a 

 half times the length : the length little more than three-eights that of 

 vertex. Pronotum about as broad as head, the anterior margin an even 

 curve. 



Colour pale yellowish ; below brighter and unicolorous, except for a 

 'io.'^ dark arcs on summit of front. Vertex with a double dark spot at 

 tip and three abbreviated dark transverse bands crossing the median 

 line at equal intervals back of it. Pronotum with two abbreviated 

 transverse lines anteriorly, and several irregular dark markings laterally. 

 Scutel with the transverse impressed line black and having each end 

 connected with the base by a black band. Elytra smoky, back of the 

 transverse veins with many small white spots, and three larger ones on 

 the costa in the vicinity of the recurved costal nervures ; membrane clear 

 smoky. Valve not exserted, plates small, broad at base, suddenly 

 narrowed beyond middle into slender acute points. 



Described from one male in the National Museum ; taken at Horace, 

 Kansas, July 28, 1891. 

 Platymetopius Oregonensis, n. sp. 



Length, ^ , 5 mm. Head rather short and distinctly narrower than 

 pronotum. Vertex rather acutely angulate ; width between eyes two- 

 thirds the length at middle, which is about twice the length at eyes ; disc 

 broadly subsulcate medially. Face, viewed from side, nearly straight, 

 very slightly concave above. Width of pronotum two and one-third times 

 the length, the latter five-sevenths that of vertex ; the anterior margin of 

 pronotum recurved behind eyes. 



Colour ferruginous, paler below, where there are no dark markings 

 except a few faint arcs on summit of front. Vertex with a small light 

 dash at apex ; its disc, together with the pronotum and elytra, minutely 

 irrorate. Elytra with a few small round white or hyaline spots scattered 

 over the surface ; partially transparent along costa and around apex ; one 

 or more of the inner apical veins dark. Valve very large and bluntly
