Hungerford: Nepid.e in America. 445 



blackened specimens, for indeed it is our lightest-colored species, 

 being of a yellowish color with a trace of green throughout. This 

 species has very prominent mesocoxae and metacoxse, which are 

 angular, having a slight tubercle on the inner side. The breast, or 

 prothorax in front of the mesocoxal elevations, is constricted and 

 small, making the coxal elevations very pronounced. 



The United States National Museum possesses, besides the type, 

 specimens from Virginia, West Virginia, Pennsylvania, Maryland, 

 Arkansas and Florida. 



I have before me a series of seventy-nine specimens from Doni- 

 phan county, Kansas, taken by Robert Guntert and W. J. Brown; 

 ten from Douglas county, Kansas, and forty specimens taken by 

 Mr. W. E. Hoffmann and myself from the following places in 

 Minnesota: Lake Johanna, Phalen lake and Minnehaha creek, all 

 near the twin cities. We have also taken it in other parts of the 

 state. Careful study of ample material, well distributed, shows 

 that by far the commonest size is, total length, two inches, with re- 

 spiratory tube three-fourths inch! The length of hind femur rel- 

 ative to abdomen varies, sometimes attaining the front margin of 

 the genital segment and sometimes falling somewhat short of this. 

 The eyes are transverse and somewhat protuberant. The jugse fit 

 closely against the tylus. The lateral prolongation of the penulti- 

 mate segment of the antennae is less than half the ultimate. The 

 front femora are very slender and coxae long. On page 156 of the 

 University of Kansas Science Bulletin, vol. XI, where I give an 

 English translation of Doctor Montandon's description in French 

 of R. protensa, I should have written, "Anterior femora quite slen- 

 der, but scarcely a fifth longer than their coxae," instead of "as long 

 as" — a careless error.
