In the youngest (Chiriqui) male before me the face is reddish, brightest on the upper surface of the frons, 
labrum reddish, fuscous at the middle of the free margin, labium yellowish unmarked. Even when the 
frons and nasus have become blue-black, the rhinarium may be pale, and red still present on the sides of 
the labrum (Uacarizal). In none of the present material has the labium become entirely black as the 
Jabrum has. 
In the three females the face is green, labrum and labium yellowish, each with a median blackish band; two 
of the three have some pruinosity on the ventral abdominal surface.

Taken in January (Gualan, Cachoeira), February (Amazon ®, Uacarizal), March 
(Amazon ®), and December (Rio Paraguay). 
The resemblance of this species to Rhodopygia hollandi has been pointed out on 
page 319. The two have been taken in the same locality (Cuyaba), at possibly the 
same time of year (January ?). Perhaps this is a case of mimicry. 
* To the male taken at Livingston, Feb. 18, 1905, Mr. Williamson has attached this note: “ At Livingston 
a Carib called dragonflies ‘St. John’s Horses,’ and gave as Spanish name the translation of this. I was unable 
to understand the Carib name.” :
