mens I have seen especially in the color of face. From coronatus 0. & B. 

 it differs in larger size and especially in color pattern of pronotum and 

 elytra. 



Paraholocratiis viajor, n. sp. 



Similar to viridis but larger, the vertex more broadly rounded and 

 with the margins drawn out into a thinner edge, the anterior border of 

 pronotum less distinctly arched; the elytra shorter, reaching only to 

 base of pygofer in female. Color uniformly green, similar to viridis 

 though usually a little lighter green, the black line under the margin 

 of the head wanting in the females, the tip of elytra in males and of 

 ovipositor in females tinged with light brown. Length of female 7.5 

 to 8 mm. and male 5.75 to 6 mm. 



■Head broad, anterior border broadly rounded, the margin very thin, 

 length at center about three-fourths the width between eyes ; occiput 

 slightly concave, front only slightly convex, clypeus, parallel sides about 

 one-fourth longer than wide, lorae narrow nearly reaching margin of 

 cheek; pronotum about twice as wide as long, anterior border slightly 

 arcuate between the eyes, hind border convex; elytra short, in female 

 reaching base of pygofer, in male extending slightly beyond tip of 

 abdomen; venation as in viridis. 



Genitalia: Last ventral segment distinctly longer than preceding; hind 

 border distinctly convex and sinuate, the pygofer with lower margin 

 produced apically and distinctly though obtusely angled exceeded by the 

 ovipositor by about one-fourth its length. Male valve very short some- 

 times hidden, plates narrowing shortly to about the middle and extended 

 in slender upcurved acute points margined with fine cilia, the tips reach- 

 ing the lower angle of pygofer which is produced dorsally appearing 

 obliquely truncate in lateral view. 



Specimens of this form have been taken at Orono 1913 and 1914, also 

 at Castalia, Ohio July 27, 1900, Columbus Aug. 30, 1904, and a series of 

 three females and four males at Steubenville, Ohio, Aug. 1904. 



At Cedar Point, Ohio, 1910-1911 this form was taken both as nymphs 

 and adults in considerable numbers on the swamp meadow grass Cala- 

 magrostis canadensis which appears therefore to be its normal food 

 plant. This with the apparent constancy of the adult characters seems 

 to confirm the definition as a distinct species, viridis where observed in 

 larval form has occurred only on Stipa spartea.
