Copa Cabana 2, Santa Cruz ?, Sao Paulo (Hempel, coll. A. N.8S.: 1 ¢,lor. @,1citr. 2), 
Santa Anna do Japana (Moenkhaus, coll. Adams: 1 citr. 2), Rio Grande do Sul (coll. 
P. P.C.,ex coll. Selys: 1 3,1 or. 9); West Inpiss, Cuba? (Wright, M. C.Z.: 1 bl. 2 ), 
Jamaica 3, Puerto Rico ! 2. 
The Mexican specimens were taken between January and April. 
The citron, orange, and black females are distinguished by the absence of black on 
the thorax, by the possession of a mid-dorsal black thoracic stripe only, and by the 
possession of black mid-dorsal and humeral stripes, respectively. The citron female 
is not yet known outside South America. The name floridum, without any description, 
was used by Hagen! (J. ¢. p. 810). The individuals from Brazil, of both sexes, have 
usually one more postcubital on both front (7) and hind (6) wings than the majority 
of Mexican and Central-American examples possess. 
Legion 4. PROTONEURA. 
The following characteristics apply to the members of this legion * which I have 
been able to examine, whether from the Old or the New World; they have not been 
mentioned by de Selys in his general descriptions of 1860 and 1886. 
Antenodal cells two f on all the wings; females without a vulvar spine ; tarsal claw usually toothed, although 
the tooth is very small in Neoneura palustris, and is absent in Selysioneura. 
The genera of the present fauna are separable as follows, some of the characters 
being here stated for the first time :— 
I. Median lobe of the Jabium bifid in its apical fifth at most, the two divisions so 
formed being hardly as long as the width of the interval separating them ; the 
normal submedian cross-vein nearer to the second antecubital than to the first ; 
a second, or supplementary, submedian cross-vein between the base of the wings 
and the level of the first antecubital; superior sector of the triangle ending 
beyond the half of the wing; a rudiment of the inferior sector of the triangle 
present, which ends against the lower side of the quadrilateral at one-third or 
less of the length of the latter; biserial hairs of the basal half of the second 
and third tibize more than twice as long as the intervals separating them ; most 
of the cells of the apical third of the wing with their longer diameters at right 
angles to the longitudinal veins; nodal sector arising near the seventh post- 
cubital or more remote (oftenest near the ninth) on the front wings, near the 
sixth or more remote on the hind wings; ultra-nodal sector arising at least 
seven (front wings) or eight (hind wings) cells proximal to the pterostigma ; 
18-29 postcubitals on the front wings, 17-26 on the hind . . . . . . . PaLmMnema. 
* T regard this legion as possessing the most specialized venation, by reduction, of all the Agrionine, and 
hence cannot agree with Prof. Férster’s view that his Selysioneura is the most primitive of all known Proto- 
neuran genera [Termeszetrajzi Fiizetek, xxii. p. 108 (1900)], if “ primitivste ” implies an “ Urthier.” 
_ + The only exceptions appear to be Protosticta simplicinervis and Platysticta auriculata of Celebes and New 
Guinea, which have three (Selys, 1886, p. 157).
