Transactions of the American Entomological Society, 17: 38: 1890. 



Adult, male. — Color black and dark brown. 



Head : face, including labrum, clypeus and front, white ; labium 

 black with pale spots on sides ; vertex black. 



Thorax : dark brown with obscure black on shoulders of the 

 mesepimera and dorsal border of the metepimera. 



Abdomen: segments 4-10 and anal appendages black; sides of 

 terga i and 2, caudal half of the dorsum of 2, and proximal half 

 or two-thirds of 3, brown becoming pollinose. 



Female. — Labrum black, with yellow spots on sides ; thorax 

 with a broad, dark dorsal band, and obscure irregular black marks 

 on the sides ; abdomen with pale mesal spots on base of terga 4-7 

 inclusive; vulvar lamina short (about one-seventh as long as 9), 

 the tips remote from the small ventral knobs on segment 9. 



Measurements : total length, male 36, female 33 mm. ; length of 

 abdomen, male 24-25, female 22 mm. ; length of hind wings, male 

 26-27, female 24-25 mm. ; width of hind wings, male 8.5, female 

 7 mm. 



Specimens in collection of P. P. Calvert examined. One speci- 

 men in Yale University collection from Norway, Maine, collected 

 by S. I. Smith.

Genus Celithemis Hagen 



Nymphs. — Head : lateral setae 7-10 ; abdomen with dorsal 

 hooks on segments 4-7 ; segments 8 and 9 with long straight 

 lateral spines ; superior anal appendages not decurved. 



Adults. — Wings with less than ten antenodal cross-veins ; proxi- 

 mal and distal ends of stigma parallel, the latter supported by 2-3 

 cross-veins ; triangle 3-sided, considerably farther distad in the 

 front wings ; vein M„ not sinuate, subtriangle absent ; Cuj arising 

 exactly from the caudal angle of the triangle in both wings ; hind 

 margin of the prothorax bilobed and with a fringe of long hairs ; 

 male abdomen without a hook on ventral surface of i ; transverse 

 carinae on abdominal segment 3, and frequently a transverse 

 median groove on 2 and 4. The wings are nearly always spotted 

 with dark brown and are more or less flavescent. 



Habits of the genus are very similar to other Libellulids. The 

 adult, however, is not so swift on the wing as the more common 

 Libellulas and is much more easily captured.
