Enallagma calverti, sp. nov. 



Abd. 23-25 mm., hind wing 17-19. 5 mm. 

 Prothorax greenish black, the following 

 pale (bluish): sides; a transverse line on 

 anterior lobe; the hind margin and a 

 cuneiform spot on each side of posterior 

 lobe. Thorax with a rather narrow mid- 

 dorsal stripe (sometimes divided by a mere 

 line of blue, most distinct anteriorly) and 

 a very narrow humeral stripe, wider in 

 front, especially at the suture, and a spot 

 on second lateral suture, black. A wide 

 ante-humeral stripe, eqi'.al to or wider than 

 the mid-dorsal black stripe, blue. Abdo- 

 men blue, the following black: a spot on 

 base of I ; a transverse lunula (convex side 

 forward, doubly concave behind) near apex 

 and a nariow marginal b:)nd on 2; an 

 apical spot connected with marginal band 

 on 3 and 4; apical third of 5, two-thirds 

 of 6, five-sixths of 7, and all of 10. 



Superior appendages short, one-fourth to 

 one-third as long as 10, blunt, with the 

 apex directed downward and slightly 

 notched in profile; the upper limb thick 

 and rolled inward, the lower limb thin, 

 rolled inward and upward, appearing like 

 a small, rounded, inwardly projecting shelf 

 on the lower edge of the apex of the 

 appendage. In profile the upper apical 

 angle is very obtusely rounded, the lower 

 slightly notched. Inferior appendages 

 longer, two-thirds as long as 10, rather 

 slender, tapering, slightly curved upward, 

 directed upward and backward, the lower 

 margin convex throughout.

To tliis species I also refer i $ , 

 Wellesley, Mass., May 13; 1 <?, prob- 



ably from Wellesley, presented by S. F. 

 Denton; and i <J , eastern U. S., 

 exact locality uncertain, the only 

 diflerence apparent being that the 

 inferior appendages in profile seem to 

 be somewhat more slender and less 

 .strongly convex below. 



I take pleasure in naming this 

 species for Mr. P. P. Calvert, whose 

 "Introduction" to this group of our 

 fauna fills a long-felt want and will do 

 much to promote the studv of these 

 interesting insects. 



Enallagma carunculatum, sp. nov. 



Abd., 22.5-27; hind wing, 17-20 mm. 

 Prothorax with the anterior lobe trans- 

 versely lineate with pale; posterior lobe 

 with pale margins and cuneiform lateral 

 spots; the latter are small, narrow, or even 

 may be wanting. Thorax with the mid- 

 carina black or lineate with pale; mid- 

 dorsal dark stripe broad; humeral stripe 

 of moderate width, variable, widest just 

 behind suture; ante-humeral pale stripe 

 moderate to narrow, varying from nearly 

 twice as wide to only two-thirds as wide 

 as the humeral dark stripe. Abdomen black 

 as follows: a quadrate spot on base of i; 

 an apical orbicular spot broadly connected 

 to posterior marginal band on 2; apical 

 half to three-fifths of 3, 4, 5 with a longi- 

 tudinal band, pointed anteriorly, widened 

 before margin; two-thirds to three-fourths 

 of 6; all of 7 except a narrow basal ring; 

 all of 10, widest on basal and apical mar- 

 gins ; S and 9 blue. 



In profile the superior appendage, includ- 

 ing the projecting tubercle, is half to two- 

 thirds as long as to, the inferior appendage 

 shorter, equal to sup. app. without tubercle, 

 stout, directed moderately upward, the upper 

 margin concave, the lower strongly convex. 

 Superior appendage as broad at base as the
