8. Superior appendages black, cylindrical, slightly 
curved downwards, scarcely dilated at the apex, sub- 
obtuse, longer than the 9th segment. Inferior appen- 
dages black, shorter, longer than broad, very concave 
above, the apex scarcely excised, but each angle is there 
produced into a straight tooth-like process. In the 
middle of the 9th segment beneath are two contiguous, 
rounded, scale-like lobes. 
?. The 9th and 10th segments very short above, and, 
with the appendages, elevated at an acute angle with the 
line of the rest of the abdomen (the 8th segment also 
short, cut off very obliquely above) ; appendages as long 
as, or longer than, the 9th and 10th segments combined, 
black, very hairy, straight, subcylindrical and acute; 
immediately below them is a black, very hairy, cushion- 
like prominence, slightly excised on its apical edge. 
The vulvar scale forming two slender, laterally com- 
pressed, contiguous black blades, 1} mm. long, each 
subobtuse at the apex; atthe base of these blades above, 
are two short, slender, brown styles, and above these are 
two longer, divergent, black cylindrical styles. 
Length of abdomen, male, 28—30 mm.; female, 
30—31 mm. Length of posterior wing, male, 25—27 
mm.; female, 29 mm. Expanse, male, 52—55 mm.; 
female, 58—59 mm. 
Hab. Intaj (or Intac), Ecuador (Buckley). I have 
examined three males and two females. 
In general structure this is allied to the Chilian 
G. paradoxa, Brauer, and it is possible that Gomphoma- 
cromia should more especially be limited to these two 
species; but it is abundantly distinct specifically, not 
only in colour, but also in structure. The sectors of the 
arculus are more decidedly petiolate than in any other 
species of this section of Corduliina (excepting the ano- 
malous African form just described by de Selys as 
Neophya, C. R. Soc. Ent. Belg., 1881, p. xvi.); the 
costa wants the coarse serration seen in G. paradoxa. 
The extraordinary anal structure of the female is quite 
analogous to that of G. paradoxa; but the elevation 
of the last two segments so separates them and the 
appendages from the much elongated vulvar scale, as to 
cause the apex of the abdomen to assume a furcate 
appearance.
