supporting surface, which, with the structure and position of the 

 tibiae and femora, make the hind legs powerful jumping organs. 

 The adults are extremely variable in size, structure, color and habits. 

 (Fig. 18). Our collections and notes show that the first individuals 



to reach maturity 

 are males with abor- 

 tive wings and short 

 elytra. All the early 

 maturing individ- 

 uals, both males and 

 females are dark 

 colored, occasionally 

 jet black and are 

 sometimes without 

 white markings. 

 Late in the season 

 males and females, 

 both short- and 

 long-winged forms, 

 are lighter colored, 

 some being even light 

 brown. An occasional male and a larger number of females develop 

 complete wings for migration, and these are the forms which are 

 generally obtained by collectors on various kinds of vegetation. 

 However, the major portion of the insects have abortive wings 

 and remain on the bogs. As far as observed onfy the dark-colored 

 alate forms were able to fly. The light brown females, with both pairs 

 of wings well developed, but possessed of little or no power of flight, 

 have very indistinct veins on the elytra.

The following is a detailed description of the adult: 



Adult. — -Vertex short and broadly rounded; disk depressed but slightly raised in 

 center; side and hind margins elevated; bounded in front by a pair of carinae which 

 meet at the apex in an obtuse angle. Front prominent; sharply separated from the 

 genae by parallel carinae; with distinct median and an obscure inner pair of carinae. 

 Beak extends downward and backward between the front coxae. Eyes prominent, 

 usually brownish, revealing at times whitish markings. 



Pronotum short; sides extended downward to base of front coxae and expanded 

 into large rounded lobes. Scutellum broadly triangular. Front wings coriaceous. 

 In short-winged forms they are convex or spoon-shaped, but in long-winged forms 

 are more flat. Veins run parallel and branch mostly near the base and with two or 

 three series of cross veins near apex. There is however no constancy in the 

 venation of either long- or short-winged forms. Median portion of space between
