114 THE CANADIAN ENTOMOLOGIST 



rastrate, the corium merely punctate. Margins of emboHum and of 

 clavus elevated. Lower surface and legs pale; posterior tibia 

 fringed with brown hairs. Metaxyphus very short, acuminate. 

 Strigil rounded, 5 striae, diameter 0.1 mm. 



Male palae cultrate, somewhat produced at the base, the 

 length three times the greatest height. Pegs blunt, elongate, 

 24-33 in number. The distal ones are somewhat longer and 

 crowded, and may be displaced into two irregular rows; the main 

 row begins midway the base and rises in a curve after the first 

 half dozen pegs; then follows the upper margin, but at some dis- 

 tance from it. A second row of peg-like spines along the lower 

 margin, about 13^ to 2 times the length of the pegs. Tibia sub- 

 globular, about as high as the pala. Femur oblong, a little less 

 than twice as long as wide, the stridular area covering the proximal 

 half and consisting of short spines set in transverse rows. Female 

 palae cultrate, not produced at base, slightly more than three times 

 as long as wide, broadly joined to the tibia. Tibia rounded oblong, 

 tapered proximally, twice as long as high. Femur oblong, 23^ 

 times as long as wide (the width at base in P. gillettei is two-thirds 

 the length) with stridular (?) spines on the surface as in P. gillettei. 

 Second leg: Femur 2)^ times the length of the tibia, the latter 

 equal to the claws,* and \]/^ the length of the tarsus. Length, 

 53^-6 mm.; width across pronotum, \}/2 mm. 



Types 2 a" and 2 9 from White Plains, New York, collected 

 in August and September by J. R. de la T. Bueno. Other speci- 

 mens have been examined from Washington, D.C. (coll. W. L. 

 McAtee) Oglethorp, Georgia (coll. T. C. Bradley) Hadley, Mass. 

 (coll. C. A. Frost) and Valhalla, N.Y. (coll. Bueno). The species, 

 therefore, appears to be distributed pretty widely up and down 

 the Atlantic Coast of the United States. 



Variation. — Some twenty specimens have been examined in 

 addition to the described types. These individuals show a wide 

 range of variation, such that the extremes would seem to belong 

 to different species were it not for the intergradation. The writer 

 has been unable to find any constant character, however, which 

 would serve as a basis for discrimination. The smallest (White 



*Through a lapsus calami these are called "spines" in the description of 

 P. Gillettei (1. c, p. 339).
