Last ventral segment of the female rounded. \'alve of .the 

 male large scarcely angulate at apex; plates triangular, on their 

 suture shorter than the valve; terminated by the long setae; 

 the brown apex of the pygofers much sur])assing the plates.

This insect has about the form and size oi frontalis l)tit it is 

 of a bright fulvous color with the elytra mostly opake and the 

 markings almost or quite obliterated from the base nearly to 

 the apex of the ante-apical areoles; vertex and scutellum more 

 yellowish with indistinct pale vermiculate lines; oblique costal 

 veinlets brown on a concolorous ground; face almost uniformly 

 ]jalc yellow with the basal angular pale line rarely indicated. 



Last ventral segment of the female rounded behind with a 

 blackish arcuate mark either side which gives it the appearance 

 ()i being strongly produced on the middle. \^alve of the male 

 ovate-triangular, its margins arcuated to the obtuse apex; 

 plates large, triangular, exceeding the valve by its own length; 

 strongly ciliate on their outer m.argins; jn-gofers slender, longer 

 than the plates. 



Prof. Osborn's types were from Cold Spring Harbor. Long 

 Island. N. Y. About Buffalo it is not uncommon among the 

 hills at Golden and Gowanda and it has been reported from 

 Pennsylvania and Ohio. 



1.]. Platymetopius dorsalis Ball. 



Platym(.'ti_])ius frontalis var. dorsalis Ball. Ent. Xews, .\x, p. KU, 1!)()!». 



I cannot agree with Dr. Ball in placing this as a variety of 

 frontalis. It seems to me very distinct and withall a difficult 

 species to place. It is fulvous and pale yellow in color and has 

 much the aspect of a small Mesamia vitellina but it has the ver- 

 tex of a Jliamnotcttix and the front of a Platymetopius, to which 

 genus I think it is most closely allied by its venation and struc- 

 tural characters. The anterior edge of the head is obtusely 

 rounded as compared with the allied species. The lower sur- 

 face, vertex and scutellum arc ])alc yellow and immaculate. 

 The pronotum and elytra are bright fulvous with coppery 

 reflections, with the sides of the pronotum, costa at l^ase, apical 

 areoles and a vague saddle across the apical half of the clavus 

 yellowish. I have seen only the unique type from Kansas 

 kindly loaned to me bv Dr. Ball.
