side of dorsum in its proximal half or more, 10 pale blue with 

 a metallic green spot each side of dorsum at base ; superior 

 appendages much smaller than the inferiors, each of the latter 

 with two black-tipped hooks. 9 Abd. segs. 8 and 9 dark metal- 

 lic green, sides inferiorly pale, 9 with a mid-dorsal anteapical 

 pale blue spot, or, more rarely, 8 and 9 colored as in the male, 

 ID as in the male. Abd. male 20-23, female 20-22.5 ; hind wing 

 male 13-15.5, female 14-15 mm Irene 



Of Nehalennia integricollis I have seen five females from 

 Florida, one from Thomasville, Georgia, April 28, 1903, by 

 Mr. Morgan Hebard, and the one from Malaga, New Jersey, 

 mentioned above. Of the five Florida females, one, the type 

 of the species, is from Enterprise, April 18, 1896, by Mr. 

 Philip Laurent ; it is the specimen cited in Ent. News, vii, 

 p. 302, as A'^. Irene Hag. ; two others, exact locality not re- 

 corded, are due to Dr. D. M. Castle in 1903 (cf. Ent. News, 

 xiv, p. 244) ; a fourth, "Fla. exchange," has long been un- 

 identified in the collection of the Academy of Natural Sciences 

 of Philadelphia, while the fifth, from Enterprise, May 17, 

 belongs to the Museum of Comparative Zoology, Cambridge, 

 Mass. Excepting this last, these females are in the collection 

 of the Academy named. 



The single male referred to this species, from Haulover, 

 Florida, in March (Museum of Comp. Zool.), may not be 

 conspecific with these females, as the extent of dark colora- 

 tion on the thoracic dorsum and the number of antenodal 

 cells are different, as has been indicated above. It resembles 

 the description of N. selysii Kirby (sophia Selys 1876) in 

 many respects, but is smaller, has the proximal and distal 

 sides of the pterostigma nearly parallel (proximal side more 

 oblique than the distal in selysii) , the posterior or inferior side 

 of the quadrilateral of front wing more than twice as long 

 as the anterior or superior side ("I'inferieur moitie plus long 

 que le superieur" in selysii), labrum with a transverse basal 

 black band ("un point median enfonce" in selysii), nasus en- 

 tirely black. The abdomen is not fully colored, 3-6 being of 

 a pale brown with a narrow transverse basal pale blue ring; 

 other differences in abdominal coloring may be seen from the
