ulus ; appendages of eighth segment of $ broadly ensiform, minutely 

 denticulate beneath, superior half pale testaceous, inferior half blackish 

 fuscous, with apical acicular divaricating appendages nearly .01 inch 

 in length ; 9-1 1 postcubitals. 



Length, 1.25 inches; alar expanse, 1.26-1.48 inches (^), 1.20 

 inches ( ? ). 3 S, 2 teneral $ , 1 teneral 9 . 



iEsclma virens Kamb. 



I have two males from the Isle of Pines, which apparently belong to 

 this species as described by Hagen ; all the green markings of variable 

 brilliancy in the dried insect were of a similarly bright grass-green in the 

 living insect, and all the darker markings, except the fuscous sutures 

 of the thoracic pleura were black. The inferior abdominal appendage 

 appears to differ from Hagen's description in being more than half as 

 long as the upjDcr, and in being docked at the tip ; the auricles of the 

 second abdominal segment are smaller than usual, and there is a mass 

 of nigro-cinereous, delicate, close pile on the dorsum of the first and 

 second abdominal segments, in the latter only at the base ; the pos- 

 terior half of the wings are very slightly washed with fuscous ; antecu- 

 bitals 18-21; postcubitals 11-12. 



Length 2.90-3.16 inches; alar expanse 4.15-4.44 inches; ptero- 

 stigma, .20 inches. 2 $. 



Macromia cubensis mv. sp. 



Vertex and front above purplish (in life steel-blue) with metallic 

 reflections ; front dull yellowish-brown (as in life) ; labrum reddish- 

 brown, edged with black (as in life) ; dorsum of thorax purplish (steel- 

 blue with greenish reflections, more or less dulled in life) ; plem'a fus- 

 cous (in life brownish-yellow) with three dull-purplish stripes (metallic 

 blue in life), the middle one narrower and shorter than the others; 

 legs black, next the base within, especially in the hind pair, yellowish ; 

 wings hyaline, the posterior pair fulvous at the extreme base ; ptero- 

 stigma greyish-fuscous; membranule nigro-cinereous; abdomen bronze- 

 green with metallic reflections (as in life) with a band along the sides, 

 broader next the base, linear beyond the fourth segment, but extend- 

 ing the whole length of the abdomen, fuscous (in life brownish-yel- 

 low) ; appendage black, very short ; vulvar lamina triangularly pro- 

 duced, excised at the apex, so as to make it bifid, the segment foflow- 

 ing it carinated; tip of abdomen furnished with short cinereous hairs; 

 antecubitals 8 ; postcubitals 6-7 ; two discoidal areolets. 



Length 1.44 inches; alar expanse 2.44-2.48 inches; pterostigma 

 .10 inch. 3 ?.
