Hagen.] 362 [March 25, 



lena. L. Lydla is always larger, the tip of wings more colored ; I 

 have seen it from Louisiana, Texas, Georgia, South Carolina, Florida* 

 Of L. Axillena I possess a typical male from Abbot, from Louisiana 

 or Florida. The specimen from Georgia, agreeing very well with 

 the figure No. 47, is the smallest I ever saw, but I am not yet able to 

 find any sure specific difference. 



38. Libellula incesta. Male, No. 55, female, No. 47, 

 LeConte. 



These drawings of Abbot, both male and female, have been iden- 

 tified as L. plumbea, by Mr. Uhler, the first describcr of this species, 

 I only know L. plumbea from a male kindly communicated by himself, 

 and I have never seen the female. To contradict the founder of the 

 species would seem rather hazardous, nevertheless as the figures do 

 not agree with the description given by Mr. Uhler, I believe I am 

 correct. 7L. plumbea is of smaller size, the wings with a ferrugineous 

 tinge upon the costal margin and on the tip of the female. L. incesta 

 is a rare species in collections. I possess the male from South Car- 

 olina and Dallas, Texas, and two of uncertain locality, one of them, 

 probably erroneously, marked Massachusetts. The male agrees very 

 well with Abbot's fio-ure. According to Abbot's figure the female 

 is the size of the male, brown, thorax with a large bright yellow 

 band between the wings, commencing at the abdomen and taper- 

 ing on the dorsum of the thorax to the prothorax; abdomen bright 

 yellow, with a large dorsal fuscous band, not reaching the first seg- 

 ment ; segment eight to nine, brown ; the sutures of all segments 

 and the lateral margin finely brown; appendages short, dark broAvn; 

 feet brown; wings exactly as in the male, hyaline, the costal margin 

 from the pterostigma to the tip infuscated; pterostigma black, long. 



39. Libellula plumbea. Female, No. 1 7. April 27. Com- 

 mon. Brit. Mus. 



I gave this statement Stett. Zeit, xxiv, p. 375. I do not know 

 that my determination is correct. 



40. Lepthemis hsematogastra. 



I saw one male in the collection of Mr. Escher Zollikofer, com- 

 municated to him by Abbot. 



41. Mesothemis simplicicollis. A teneral male, No. 18. 

 Brit. Mus., April 25, June 15. Brit. Mus., male, female, No. 49, 

 LeConte. 



I have seen a type from Abbot, and possess specimens from Geor- 

 gia. The species is common nearly everywhere east of the Rocky 

 Mountains, also in Mexico and Cuba.
