water's edge, where no bertha was seen. Woods surrounding 

 the pond were of scattered turpentine trees with occasional 

 chimps of smaller ones near the water's edge. On April 25 

 he collected at four ponds about four miles east of Enterprise 

 and about a quarter of a mile north of the railroad at that 

 point. April 26 was again spent at Buckeye Homestead Pond 

 and is therefore the type locality for the species,

Distribution of Specie;s 



Of the eight species of Celithemis, eponina has by far the 

 widest range, occurring from about 23^ N to about 45° N, 

 and from Cuba, Florida, and Massachusetts on the east to 

 Texas and Minnesota on the w^est. This covers the entire range 

 of the genus except the extreme northeastern part in Alaine, 

 where elisa and martha are found, but where eponina has not 

 yet been recorded. To offset this, eponina is the only species 

 of the genus known from Texas and Cuba. The other species 

 are definitely separated into two groups, a northern and a 

 southern, the parallel 36°, so far as now known, being approx- 

 imately the dividing line between them, though one northern 

 species, elisa^ occurs as far south as Georgia. The three north- 

 ern species are elisa, monomelaena and martha; the four south- 

 ern are fasciata, ornata, bertha and amanda. Eponina and all 

 four of the southern species occur in Florida, and one, bertha, 

 is found nowhere else. Florida may therefore be considered 

 the place of origin of the genus. Fasciata and monomelaena 

 are evidently closely related, and the latter has been derived 

 from the former. Fasciata is confined to the extreme south-
