42. Mesothemis longipennis. Male, No. 23, female, No. 

 24. Brit. Mus., May 23. Not very common. Male, female, adult, 

 both pruinose. No. 40, male, female, No. 56. LeConte. 



I have seen a type from Abbot in Mr. Escher Zollikofer's collec- 

 tions, and I possess specimens from Georgia, and numerous other 

 localities. This species is even as common and widely distributed as 

 the foregoing one. 



43. Diplax albifrons. Male; female, No. 81. Brit. Mus., 

 September 1 ; male ; female, No. 48. LeConte. 



These drawings of Abbot are not so well finished as of the other 

 species, and not sufficiently so for a sure determination. I believe 

 them to represent D. albifrons, chiefly because T have seen a type of 

 this species from Abbot. 



44. Diplax elisa. No. 22. Brit. Mus. June 9. Bare. 



45. Diplax amanda. Male, No. 29, female, No. 30. Brit. 

 Mus., March 29, April 20. Common. Male ; female, No. 39. Le- 

 Conte. 



Lpossess a female from Georgia, but have never seen a male, which 

 according to Abbot's draAving, is exactly similar to the female in size 

 and color; the appendages are yellow. 



46. Diplax ornata. Male, No. 39. LeConte. 



I possess this species from Pennsylvania and Florida. 



47. Diplax minuscula. Male, female teneral and male, 

 female adult pruinose, No. 38. LeConte. 



I have seen this species from Georgia; it is quite an interesting fact 

 that the adult female becomes also pruinose. 



48. Perithemis Domitia var. chlora. Male, female, No. 18. 

 Brit. Mus., June 21. Frequent near Savannah River, Burke Co., not 

 a common sort. 



49. Wannophya bella. Male, female, No. 82. Brit. Mus., 

 April 20. Very frequent. 



I have seen this widely spread species from different localities. 



50. Nannophya maculosa. 



I have seen only two males from Abbot in Mr. Escher Zollikofer's 

 collection. 



Family CALOPTERYGINA. 



51. Calopteryx angustipennis. Male, No. 19. Brit. Mus., 

 April 18. Briar Creek, rare.
