One of the Paramaribo examples is the type. 



The two females from Surinam, in the U. S. National Museum, are 

 the smallest, and have the stigma of the front wings only 5.5 mm. 

 long, which is less than the dimensions given in the ' ' Biologia ' ' volume 

 quoted for group A. 



167. Orthemis ambirufa sp. nov. 



d\ Belonging to the group of O. levis (group CC, Biol. Centr. - 

 Amer. Neurop., p. 233). Abdomen stouter, segment 4 being 2.8 

 times as long as its width at apex, 3.2 times as long as its width at 

 base. Labrum reddish ; abdomen reddish ; no black on the dorsum of 

 8-10. Thorax somewhat faded, its color-pattern very similar to that 

 figured for levis (/. c, pi. viii, fig. 38), differing chiefly in the 

 absence of the first pale antehumeral stripe, and the more uniform 

 width of the pale mesepimeral stripe (about 1 mm. ). Genitalia of the 

 second abd. seg. apparently not different. 



Abdomen 34, hind wing 38 mm.

tf. Belonging to the group of O. levis (group CC, Biol. Centr. - 

 Amer. Neurop., p. 233). Abdominal segment 4 three times as long 

 as its width at apex : segments 8 and 9 with a mid-dorsal black band 

 about one-third as wide as 8, a little wider on 9. Labrum black. 

 Thorax much faded, its color-pattern probably similar to that of am- 

 birufa. Genital hamule with the external branch wider than in O. 

 levis or in O. ambirufa. (Cf. Biol. Centr. -Amer. Neur. , pi. ix, 



fig- 39-)
