wing at the sixth ; A in front wing arising proximal to the cu- 

 bito-anal crossvein*; cubito-anal crossvein in front wing distal 

 to first antenodal nearly or slightly more than one-half the sec- 

 ond antenodal costal spacef, in hind wing more than one-half to 



nearly two-thirds A. ftammcum. 



b 2 . M 2 in front wing arising at the fifth postnodal, in the hind 

 wing at the fourth ; A in front wing arising at or distal to the 

 cubito-anal crossvein; cubito-anal crossvein in front wing distal 

 to first antenodal from one-fourth to one-third the second ante- 

 nodal costal space, in hind wing less than one-half. 



Other species of Aeolagrion. 



Of Lcptagrion I have 2 males each of macrurum and 

 andromachc. On the basis of description and figures only, 

 clongatum, porrectum and dispar are also referred to the same 

 genus. I know both sexes of flammcum and both sexes of 

 dorsalc and dcmararnm n. sp. On the basis of descriptions 

 only, it is probable inca and obsoletum belong here. I have no 

 idea in what genus or genera the following species should be 

 placed : croceum, inornatum and rufum. 



An examination of the venational characters tabulated 

 later in this paper will show a great deal of variation in 

 relative lengths of the sides of the quadrangle. For example, 

 in the front wing the anterior side may vary in the same species 

 from about one-half the length of the proximal side to longer 

 than the proximal side. Hence characters of the quadrangle 

 based on single specimens are valueless. 



The teeth on the tarsal claws seem to offer characters of 

 value but are difficult of clear definition. Several species 

 were studied in a comparative way and the following brief 

 notes made: macnimm, tooth large, almost equalling clawi* 



*The editor calls my attention to the fact that fig. 20, pi. xviii, shows 

 A at the crossvein. A reexamination of the wings themselves shows 

 that A is really proximal to the crossvein. 



fThe space between the antenodals. 



; f the two males studied, 3 of the 4 hind tarsi are malformed (?); 

 these 3 tarsi are shortened, apparently 2-jointed, and terminated by a 

 single greatly enlarged claw, with a nearly equal inferior tooth. Since 

 this footnote was written Doctor Calvert has called my attention to 

 Child and Young's Regeneration of the Appendages in Xymphs of the 

 Agrionidae (Archiv f. Entwickelungsmechanik d. Organismen xv, 

 103, pp. 543-602, pis. xx-xxn), and he adds: "The cases to which your 

 footnote refers are probably regenerated tarsi." Child and Young's 

 paper is not in my library and I am unable to obtain a copy at this 

 time.
