Hungerford: Nepid.e in America. 441 



Notes. Tliis is the species that Doctor Montandon has con- 

 sidered a synonym of I\\ fusca P. B.* Its much smaller size (7?. 

 fusca P. B. measures 37 mm.) is not the only reason for believing 

 otherwise. Tlie anterior femora of R. kirkaldyi Bueno are not con- 

 stricted near the middle tootli as they are in R. fusca P. B. The 

 front legs and respiratory tube are both shorter relatively than in 

 Palisot's figure. This is the smallest known species in North Amer- 

 ica. It is a characteristic species, quite unrelated and distinct from 

 the others. In the first place, the antennae are much reduced. They 

 are straight, lacking any projections from the penultimate segment, 

 and often lack anything more than a constriction to distinguish the 

 terminal segment. The ultimate segment is sometimes fused with 

 the penultimate (see figs. 9 and 11, pi. XLVII), but all stages of 

 separation can be found. The male genital claspers are also very 

 distinct, as shown by figure 5 on plate XLVI. 



Specimens of this species taken by Beamer and Hungerford in 

 Cherokee county, Kansas, were identified by Mr. J. R. de la Torre 

 Bueno. They agree with the original description in lacking any 

 apical tooth or sinuosity near the apex of the femora. They measure 

 from tip of beak to base of filaments, from 24 to 30 mm., wdth the 

 filaments from 14 to 17 mm. long. I have seen the true R. kirkaldyi 

 Bueno from New York. 



In addition to the above Kansas series, I have before me the 

 following series of 127 specimens as follows: 



8 Rockbridge, Ohio, 9-30-16, C. J. Drake. 



1 Rocky Mount, N. C, 10-19-16, R. W. Leiby. 



3 St. Paul, Minn., Phalen Lake, 6-19-21, H. B. Hungerford. 



1 St. Paul, Minn., Lake Johanna, 6-26-21, H. B. Hungerford. 



4 Ramsey county, Minnesota, 1-9 22, W. E. Hoffman. 



7 St. Paul, Minn., Lake Johanna, 10-13-22, W. E. Hoffman. 



9 St. Paul, Minn., Lake Johanna, 10-14-22, W. E. Hoffman. 

 32 St. Paul, Minn., Lake Johanna, W. E. Hoffman. 



3 Lincoln, Neb., 1 male, 2 females, W. E. Hoft'man. 



39 St. Paul, Minn., Water Supply Canal, 10-18-21, W. E. Hoffman. 

 16 St. Paul, Minn., Lake Johanna, 9-24-21, W. E. Hoffman. 



4 St. Paul, Minn., Lake Johanna, 9-17-21, W. E. Hoffman. 



I have also seen a series of 170 taken by Doctor Drake in Ohio. 



These Minnesota specimens have certain characteristics which 

 set them clearly apart from the Kansas series, yet there can be no 

 mistake in considering them as belonging to the same species. Since 

 I have had a fairly good series of these insects, which are smaller
