the black is reduced to a quadrate basal spot and a very narrow sub- 

 apical transverse ring. The black on 2 has a similar subapical narrow- 

 ing, but in this segment there seems to be but little variation, and the 

 black is reduced only to about its width throughout the segment basal 

 to the dilatation just basal to the subapical narrowing. The blue on the 

 apex of 7 is variable especially on the sides ; on the dorsum it varies 

 in length but never equals the diameter of the segment ; on the sides 

 the black may reach the apex of the segment (in which case the blue 

 is a dorsal spot) or, more generally, the black is reduced and laterally 

 the blue occupies a greater length than dorsally, varying greatly in ex- 

 tent. 



Wings usually hyaline, sometimes slightly tinged and in one case 

 deeply tinged yellowish brown. 



9 : Varies more in pattern of dorsum of head than does the male; 

 the markings are yellowish above (except the postocular spots) as in 

 the male, but in the darkest female the pattern is as described for the 

 palest male, with the addition of a small spot in front of each lateral 

 ocellus ; in the palest female the head above is yellow, marked with 

 black as follows : A trilobed spot in front of the median ocellus ; an 

 edging around all ocelli ; a more or less indistinct irregular bar from 

 this black edging past the apex of the second joint of the antenna to 

 the eye ; a definite border around the blue postocular spots ; interme- 

 diates between the darkest and palest exist. 



The humeral black stripe is more or less rusty-edged, and in one 

 specimen it is reduced and is entirely rusty red except the extreme 

 upper end, which remains black. 



Apparently the same variation in black on abdominal segment i as 

 described for the male may be expected in the female. Apex of 8 

 black to the transverse row of spines in only one specimen, in the 

 others with some blue, not very variable, the integument blue in all 

 cases. Width of dorsal blue basally on 9 not very variable but the 

 length of the basal black on the sides more variable.

Acanthagrion cuyabae Calvert. 



Georgetown, January 27, 1912, a single teneral male in poor 

 condition. Dr. Calvert who examined the specimen writes 

 of it, "In appendages, blue color and pale mid-dorsal thoracic 

 carina more like cuyabae fimcnse than cuyabae, but differing
