mens. The wings have the veins, with the exception of the basally ful- 

 vous media, greenish-brown basally, becoming darker apically. The 

 cross veins between R^ and R+k-. and between the latter and M, are dis- 

 tinctly darkened. The basal areoles of the fore wings are greenish-brown. 

 The flaps are grayish to brownish in color. Beneath the insect is olive- 

 green and pruinose in fresh specimens. The legs are of about the same 

 color. 



Form : The following are the measurements in millimeters of the 

 specimens at hand : 



Length of body 40 . 5 to 42 



Width of head 18.5 to 19 



Expanse of fore wings 116 to 122 



Greatest width of fore wing 19 to 19.5 



Greatest width of operculum 9.5 



Greatest length of operculum 12 



The opercula are very large and broad, separated at base medially, 

 but overlapping quite strongly for a short distance, the outer margins 

 slightly sinuate, and the apices broadly rounding. 



Genitalia: The supra-anal plate of the male has a very broad but short 

 median process which does not equal the rounded lateral angles. The 

 uncus, when viewed laterally, is broad basally, narrowed medially, and 

 then enlarged at the apex which somewhat resembles a horse's hoof. 

 Viewed caudally it is a comparatively short and very broad sclerite with 

 its truncate apex slightly but distinctly emarginate. The last ventral 

 segment of the male is fully twice as wide as long, the margins slightly 

 sinuately tapering to the rounded, almost truncate apex. The pygofers 

 of the female have a broad and short but acutely-pointed median spine 

 which scarcely exceeds the lateral angles. The last ventral segment of 

 the female has the lateral margins practically straight and the broad 

 angular emargination of the posterior margin extends half way to the 

 base. The lateral pieces of the ovipositor each bears three slight ridges 

 followed by about ten fairly distinct, rounded teeth. 



Distribution: In the collection of the Kansas State Agricul- 

 tural college are specimens which were taken in Riley county. 

 Davis records specimens from Labette county also. As far as 

 the writer knows these are the only two records of the occur- 

 rence of this insect in the state. Davis states that it is found 

 from eastern Kansas and Nebraska to Michigan and Massa- 

 chusetts, and southward along the coast to Florida. Van 

 Duzee records it from Massachusetts, New York, New Jersey, 

 Maryland, District of Columbia, North Carolina, South Caro- 

 lina, Georgia, Florida, Alabama, Louisiana, Mississippi, Michi- 

 gan, Missouri, and Kansas. It would seem, therefore, that 

 Kansas is its western limit. 



Remarks: Concerning the song of this species Davis writes : 

 "Its song is monotonous in tone and not loud, considering the
