(Lindig 1862, M. C. Z.: 1 2); Venezveta, Puerto Cabello (Appun'), San Julian 
(Lyon, U. S. N. M.: 1 3,1 2); Ecuapor, Cuenca*®; Brazit, Para (MM. C.Z.: 1 3), 
Theresopolis in Sta. Catherina (Frihstorfer 4, coll. P. P. C. ex Mus. Berol.: 1 3, 
1 9); Paraauay, Sapucay (Foster, U. S. NV. M.: 46,12). 
Taken in January (Sapucay), February (Santa Lucia, Bkistebu, Sapucay), March 
(Sapucay), May (Atoyac), July (Don Amo, Minca, San Julian), and December 
(Sapucay). 
Mr. Williamson made the following notes at Santa Lucia on this species :—“[ ¢ | 
About shaded pools (springs) along a ravine with a rivulet. Abdomen iridescent 
prismatic scarlet.” ‘“ 2 oviposits, unattended by ¢ which may flutter near, in pools 
(springs) along ravine on either side of stream bottom.” 
The smoky-yellow colouring of the wings of some of the present material (Para ¢, 
Temax 2, Santa Fé @ ), and described? for B. longipennis, is no evidence of specific 
difference, as an analogous condition is frequently met in other Libelluline— 
é. g., Pachydiplax longipennis, Libellula auripennis. 
Although Brauer says? of this species that it “‘ kann keine Libellula s. str. sein, weil 
der Prothorax-Mittellappen breit zweilappig ist,” the hind lobe of the prothorax of the 
present individuals, including the pair from Theresopolis (and therefore some of the 
type material), conforms with the characters given for Libel/ula on page 198. 
4. Libellula saturata. 
Yellowish-brown of the base of the wings prolonged along the anterior margin to the 
stigma ; hind wing with submedian space, supratriangle, and triangle dark reddish- 
brown, one submedian cross-vein, two rows of cells between the short sector and the 
supplementary sector next below; stigma relatively shorter; genital hamule of male 
narrower than long. Abdomen, ¢ 31-36, 2 30°5-35; hind wing, ¢ 385-44, 
© 40-44; stigma, front wing, ¢ 45-5, 2 555mm. .. . saturata type. 
Yellowish-brown of the base of the wings stopping at the nodus or "proximal thereto ; 
hind wing with submedian space, supratriangle, and triangle not darker, two 
submedian cross-veins, usually one row of cells between the short sector and the 
supplementary sector next below; stigma relatively longer; genital hamule of male 
wider than long. Abdomen, ¢ 32-37°5, 9 32-35; hind wing, ¢ 37-41, 2 42- 
45; stigma, front wing, g 5-6, 9 6-675mm. . ... ... . . . . . form croceipennis. 
The typical saturata and croceipennis are completely connected by intermediates not only as regards 
colouring but also in the venation. There can, therefore, be no doubt that they constitute a single variable 
species, but it seems convenient to make use of the name croceipennis to designate those individuals 
possessing the characters given above, especially the venational here presented for the first time.
