Subfamily Agrionin^. 

 60. Lestes congener Hagen. 



Orono, Me., July 29, 1899 (Harvey). Over small pond in 

 • pasture. Abundant. 



3. Argia violacea Hagen. 



Chemo Stream, Sept. 13, 1899 (Harvey). Several speci- 

 mens seen. A very late date for this region. 



58. Erythromma conditnm Hagen. 



A single male taken at Vinal Brook, Orono, Me., Jul}^ 3, 

 1899, has the abdomen fully 30 mm. long. This .specimen has 

 on the dorsum of the abdominal segments 8 and 9 a narrow 

 median black line, which extends on 8 about seven-eighths the 

 length, and on 9 about two- thirds the length; also on 8 and 9 

 on each side of these median lines, near the end, is a small 

 round dot. These markings are not mentioned in descriptions 

 of this species and should be recorded. We have not examined 

 a large series and these marks may be normal. The books say 

 • 8 and 9 blue. ' 



8. Enallagma hageni Walsh. 



The coloration of this species is quite variable. Specimens 

 taken at the same localit}- and the same dates, and having un- 

 doubted appendages of this species, varied as follows in the 

 color of the abdomen : (a) Apical fourth of 3-5, more than 

 half of 6, whole of 7 and 10, black, (d) Apical third of 3, 

 half of 4, two-thirds of 5, the whole of 6-7 and 10, and a pro- 

 ximal dot on each side of 8, black, (c) Apical fourth of 3-4, 

 third of 5, three-fourths of 6, whole of 7 and 10, and a longi- 

 tudinal stripe on either side of distal half of 8, black. (d) 

 Apical fourth of 3-4, one-third of 5, three-fourths of 6, whole 

 of 7 and 10, and a longitudinal stripe on each side of the whole 

 length of 8, black ; the stripes are connected b}- an apical ring, 

 their proximal ends show a tendency to be connected, being 

 extended transversely, and there is a median dorsal dot between 

 the exten.sions. (e} Another specimen lacks the dorsal dot 

 and apical ring.
