those from the United States. | 
2. Libellula foliata. 
Belonia foliata, Kirby, Trans. Zool. Soc. Lond. xii. p. 333, t. 54. fig. 4 (1889) * (2 only). 
¢ (not hitherto described). rons, vertex, and labrum dark brown, becoming black in age; frons with the 
superior median groove shallow, anterior and lateral surfaces separated from each other by a moderate 
carina; clypeus and labium greenish, becoming brown later; eyes in contact for a distance less than 
half the mid-dorsal length of the occiput. 
Thorax greenish with an ill-defined brown antehumeral stripe, the whole becoming pruinose with age. 
Abdomen reddish-brown, darker posteriorly, sutures and carine black; entirely pruinose in old individuals. 
Two tufts of hairs on the ventral surface of segment 2 in front of the anterior lamina, which latter is 
inconspicuous, entire; genital hamule projecting very slightly more, if at all, than the genital lobe, two- 
branched, outer branch much the shorter; genital lobe not so wide as long, its apex obliquely subtruncate 
and almost emarginate. Superior appendages 2°5 mm. long, longer than segment 9, but not so long 
as 9+10, blackish, of the usual form in this genus ; inferior appendage one-fourth to one-fifth shorter. 
Wings as described on pages 206-7; front wings with 15-18 antenodals, 12-14 postnodals. 
Legs reddish-brown, tibie and tarsi blackening with age. 
Q. The ill-defined brown antehumeral stripe is present in this sex also. Although Mr. Kirby gives! the 
pterostigma as 5°5 mm. long, my measurements, made in 1896, from the specimens in the British 
Museum, are 4-4-5 mm., and with these his life-size figure! of the insect agrees. 
Hab. Mexico! (U.S. N. M.: 2 3); Guaremana, Purula in Vera Paz (Champion: 
1 2), Duefias (Salvin, coll. McLachlan: 1 3,1 2, the 2 labelled “ Libellula crocei- 
pennis, Selys,” in McL’s. hand); Costa Rica, Irazu (Rogers: 4 6,2 2). 
The male which Mr. Kirby doubtfully referred! to this species is perhaps L. herculea, 
* Mr, Williamson reported ** this species also from Tennessee, but, the single specimen having been lost, 
he wrote later (80. x. 1903), “I believe it had better come out of the Tenn. list.”

study.
