12. Hctcragrion auiazoniciiui Selys 



Described (de Selys 2) as possibly distinct from cinna- 

 moincum, which he regarded as a race of auraiitiaciiin. In 

 his description he speaks of it as larger than other species of 

 the group (abdomen 34, hind wing 2y) but his description of 

 aiirantiacuui (i) gives the same measurements for that species 

 except that the hind wing is 26. There is nothing distinctive 

 in the description and the indefinite locality, "pris par ]\I. Bates 

 sur TAmazone'', will make the identification of this species 

 impossible in the future if the type female is not preserved. 



13. Heteragrion consors Hagen 

 Figures 24, 80, 81, 145 



The Hagen collection contains a male in a good state of 

 preservation. It bears the printed labels "Hagen" and 

 "Winthem" ; and the following written labels : two black- 

 bordered labels, one "H. consors Hagen", the other "Bahia", 

 another "//. consors" , and "penis drawn" by Kennedy. This 

 specimen is the type. The female has not been described. 



The profile is like figure 65. The arculus is distal .6 to .8 mm. 

 to the cubito-anal cross-vein, and the anal vein separates from 

 the posterior border i.o to 1.3 mm. distad to the cubito-anal 

 cross-vein. 



14. Hctcragrion obsolctum Selys 



Described (2) from a single male from Cochambu, southern 

 Brazil. The species seems to have no relatives in the group in 

 which de Selys placed it, though he compared it with ochraccuni, 

 the male of which, however, he knew only from Hagen's descrip- 

 tion. It is a small species (abdomen 31, hind wing 25, while 

 other species of the group have the abdomen 37 to 41, and the 

 hind wing from 23 to 30), and seems very distinct by its blue 

 and greenish pale markings and its color pattern.
