Superior appendages pale, black at tip, about half as long as 10; viewed 

 from above, somewhat divergent, especially on the inner sides, with a 

 small ante-apical denticle on the inner side ; viewed in profile, the upper 

 margin is straight, the apex truncated almost at right angles, upper apical 

 angle slightly rounded, lower apical angle produced slightly downward 

 as a minute point, lower margin of the appendage with an oblong process 

 which is as wide and nearly as long as the appendage itself, projecting 

 downward and slightly backward (caudad). Inferior appendages, viewed 

 from below, produced on the outer side into a slender conical process 

 which reaches as far backward as do the superiors and whose apex is 

 acute and slightly upturned. 



Wings hyaline ; pterstigma brownish to blackish with a narrow linear 

 yellow border immediately within the enclosing veins, surmounting less 

 than one cell, costal margin the longest, proximal the shortest, distal and 

 posterior subequal ; arculus at the second ante-cubital, its upper limb 

 slightly longer than the lower ; upper side of the quadrilateral on the 

 front wings less than half as long as the lower side, on the hind wings 

 almost half as long as the lower side ; inferior sector of the triangle arising 

 at the submedian cross-vein (Florida cf ), o r very slightly in front thereof 

 (less than the length of the cross-vein, New Jersey <^), and ending proxi- 

 mal to the level of origin of the nodal sector ; superior sector of the tri- 

 angle ending between the levels of origin of the nodal and ultra- nodal 

 sectors ; submedian cross-vein nearly mid-way between the levels of the 

 first and second antecubitals ; front wings with 12 (Florida (J 1 ), 1 1 (N. J. $) 

 postcubitals, the nodal sector arising nearest the sixth ; hind wings with 

 9-11 postcubitals, the nodal sector arising nearest the fifth ; ultra-nodal 

 sector arising 3 (2 in one wing) cells proximal to the inner brace vein of 

 the pterostigma on the front wings, two cells on the hind wings ; three 

 antenodal cells on all the wings. 



Dimensions. Abdomen 35-36.5, hind wing 21.5-23 mm. 



Habitat. Manumuskin, New Jersey, June 23, 1902, one

Named for the active and enthusiastic collector who has 

 added so much, during the last few years, to knowledge of the 

 New Jersey insect fauna. 



Provisionally, I refer this species to the Brazilian genus Tila- 

 grion Selys, for reasons given below ; it may be that the dis- 

 covery of the female will indicate other relationships. In 

 making comparisons of this species with Tclagrion, I have 



used Selys' descriptions* of course, and also two males of T. 

 longum from Brazil, one of which bears the label "A. longissi-
