NEPHEPELTIA.—ORTHEMIS. 231 
1. Nephepeltia phryne. (Tab. IX. figg. 31-33.) 
Libellula phryne, Perty, Del. Anim. Art. Bras. p. 125, t. 25. fig. 3 (1830-1834) *. 
Nannophya phryne, Hagen, Stett. ent. Zeit. xxviii. p. 91 (1867) *. 
Nannothemis phryne, Karsch, Ent. Nachr. xv. p. 258 (1889) °. 
Nephepeltia phryne, Kirby, Cat. Odon. pp. 44, 183 (1890) *. 
Perty’s description ' says nothing of pale spots on the thoracic dorsum, while the wings are “ omnes hyaline, 
nitide.” All the present material possess a pale yellow, elongated, inferior antehumeral spot. Some 
of the Guatemalan males have the basal half of the wings pale yellow. On page 200, anted, one of 
the characters given for Nephepeltia is ** front wings with only one post-triangular row of cells between 
short sector and upper sector of triangle,” while Mr. Kirby in his characterization of Nephepeltia says 
“trapezium of fore wings followed by two and then more cells.” This apparent discrepancy is due 
to his having counted the cells between the short sector and the lower sector of the triangle, as he 
usually does whenever, on front or hind wings, the upper sector of the triangle arises from the outer 
side and not from the hind angle. 
As compared with Prof. Needham’s figure of the appendages of Edonis helena ¢*, the superior appendages of 
phryne & have their inferior tooth at almost three-fifths their length, and the remaining two-fifths more 
strongly upcurved. 
Hab. Guatemata, Puerto Barrios (Hine, O. S. U.: 28) [Deam: 11 3], Los 
Amates [ Williamson: 1 3 | (coll. eyusd.); Panama [1 ¢ ].—Gurana, Surinam ?; 
Brazit, Piahuit, Rio ?, Bahia [1 ¢ labelled “ Dythemis apicalis, Mus. Berol. Hag. 
Amer. Neur. p. 317” in Hagen’s hand], Sta. Catherina [1 3] (MZ. C. Z.). 
Taken in mid-January at Los Amates, late February and early March at Puerto 
Barrios, May at Panama. 
The locality-label on the specimen marked “ Dythemis apicalis,” &c., is “ Rio ; 
Bahia,” also in Hagen’s hand. I leave to others the ascertainment of the actual 
locality; compare, however, Hagen?, where he also states that the specimen is 
identical with Perty’s types in the Munich Museum. 
ORTHEMIS. 
Orthemis, Hagen, Syn. Neur. N. Amer. p. 160 (1861); Brauer, Verh. zool.-bot. Ges. 
Wien, xviii. pp. 367, 729 (1867); Kirby, Trans. Zool. Soc. Lond. xii. pp. 263, 286 
yellow, elongate, inferior, antehumeral spot ; abdomen subequal in width (that of the ¢ distinctly wider at 
base and at apex), the pale yellow spots, or rather stripes, on segments 3-7 wider than in the ¢, almost as 
long as 3, two-thirds as long as 6 and 7; vulvar lamina reaching to one-third of the length of the lateral 
margins of 9, not attaining the gonapophyses of 9, its apical margin slightly bilobed ; appendages longer 
than 10, subequal to 9. 
The genus Edonis, Needham, Proc. Biol. Soc. Wash. xviii. p. 113 (1905), is apparently closely allied to 
Micrathyria and Nephepeltia, but differs from both of these in having the sectors of the triangle of the hind 
wing arising from the same point, as well as differing from each in other characters. The figures of the 
genitalia and appendages of the male of the single species, H. helena, from Brazil, given by Prof. Needham, 
closely approach, although are not identical with, the form of these structures in the two species of 
Nephepeltra. |
