labels "cinnamomeum" all in de Selys' handwriting. This is 

 clearly specifically distinct from aiirantiaciiin in the same col- 

 lection and also figured by Alenger (figures 121 and 122). 

 May not this specimen labelled by de Selys citnianioineuju be 

 ochraceuni? De Selys knew the latter species directly only 

 from a single teneral female. As evidenced by the female in 

 Hagen's collection we know that Hagen, who possibly knew 

 both sexes of both cinnamomeuni and ochraccum, regarded 

 the former as a synonym of the latter. 



10. Heteragrion beschkii Hagen 

 Figures 20, 82, 83, 139 



A female, doubtfully referred to this species, has been de- 

 scribed (de Selys 2) but the description is inadequate. The 

 species is represented by a single male in the Hagen collection. 

 This has two written pin labels "H. beschkii", one of which 

 is black-bordered, and another written label, "Brasil-Xew 

 Freiburg, Beschke — Argya aurantiaca." The small printed 

 pin label ''Hagen" and written label "penis drawn" by Ken- 

 nedy are also attached. This specimen, which is in good con- 

 dition, is the type. 



The profile of the male is like figure 65. The arculus is 

 distal to the cubito-anal cross-vein .5 to .7 mm., and the anal 

 vein separates from the posterior border .7 to .8 mm. distad to 

 the cubito-anal cross-vein.

This species was recorded from Bahia, Brazil and from 

 Buenos Ayres by de Selys (i and 2), the specimens from 

 Brazil in his collection, the specimens from Argentina in
