gular green spot ; segments three to eight, with similar brown spots, 

 smaller on segments six to eight ; ninth segment each side with an 

 apical green spot; tenth segment brown; appendages very short, 

 rhomboidal, broad ; wings with a yellowish green tinge ; pterostigma 

 small, narrow, rufous ; membranule grey. 



Length 90 mill. ; alar exp. 130 mill. ; pterostigma b\ mill; append. 

 2 mill. 



The description is made from Mr. Abbot's drawing, which is well 

 finished, together with some notes by Mr. Abbot on the foot of the 

 sheet. The description given by me in the Stett. Zeit., is incorrect 

 in several places, and carefully revised again from my notes and a 

 diagram of the pattern of the abdomen. The very short rhomboidal 

 appendages are very unusual, and induced me chiefly to describe this 

 species only represented by a drawing. The dimensions are very 

 large, and taken from the figure; they are doubtless of the natural 

 size, as all other figures by Mr. Abbot. The supposition that per- 

 haps the appendages are figured from a broken specimen seemed to 

 be inadmissible, as the species is stated to be common through the 

 greater part of the year. Perhaps 2E. Abboti belongs as female to 

 the supposed male of M. virens, the female of this species not being 

 well known. 



4. iEschna heros. Female No. 59, LeConte. 

 The eyes are blue. 



5. iEschna virens. Male No. 58, LeConte. 



This figure is very interesting ; Mr. Uhler supposed it to repre- 

 sent J5. clepsydra, but the size is much too large, and the pattern of 

 the color different. The membranule in JE. clepsydra is darker on 

 the anal margin, in the figure darker on the opposite margin. I am 

 almost sure that Abbot's species is JE. virens, but this species is not 

 yet represented in any collection from Georgia. I possess them from 

 Venezuela, Panama, Cuba, and perhaps from Florida. Their occur- 

 rence in Georgia would not be exceptional, as several southern spe- 

 cies have a similar distribution. 



6. iEschna quadriguttata. Male No. 12, Br. Mus., Mar. 

 22. Not very common. 



7. iEschna furcillata Say. Male No. 51, LeConte. 



The shape of the abdomen of the male with the third segment very 

 much contracted, and the inferior appendage widely emarginate down 

 to the middle, induce me to identify Abbot's figure with this species, 

 not before known from the Southern States. All specimens known are
