316 NEUROPTERA. 
(Altamira, Camaron), July (Altamira, Tlacotalpan, La Guayra), September (Altamira, 
S. Luis Potosi), and November (Sapucay ¢ ). 
The specimens above enumerated under mooma have the same venation as those of 
iris, iii. Extra-faunal individuals with venation as of iris, ii., but with the wing-bands 
of the female as in mooma, are two males and a female from Cordova, Argentina 
(M. C. Z.). Asis evident from the notes and photographs which he has kindly sent 
me, the two females from San Isidro, Argentina, described by Dr. Ris * in the paragraph 
beginning “2 @ endlich zeigen in der Dreieckgegend,” &c., have the wing-bands as in 
mooma and the venation of Zris, i.

The Matamoros example approaches, in wing-pattern, our fig. 18, Tab. VI., but the colours are much paler— 
pale yellowish-brown ; there is the faintest trace of a smoky brownish band, ‘5 mm. wide, along the hind 
margin of the hind wings from the transverse nodal band to the apex. This brownish margin is also 
faintly indicated in one female from Carrizo Springs, Texas (Schaupp, M. C. Z.), while in the other female 
from that locality it is more distinct and yellowish-brown. These three specimens consequently recall 
one of the conditions found in all the Floridan Perithemis which I have seent, while two females from

+ A brief note on the Floridan females was published in 18938, They vary much in having the transverse 
proximal (triangle) and distal (nodal) bands separate or fused on front or hind wings, or both (when separate 
the intervening space is deep yellow), and in having the proximal band connected, or unconnected, with the 
base on the hind pair (in no example before me does a complete connection between proximal band and base 
of the front wings exist), In all, the transverse distal band of the front wings extends to the stigma, and 
from this band a marginal band of the same colour (brown), *5-1°5 mm. wide, extends along the hind margin 
to the apex. When this hind-marginal band of the front wings is best developed, there remains a colourless 
area of only 3mm. length near the apex. The venation of these females is that of iris, iii., of the text above 
(occasionally as in iris, ii., but then with the discoidal triangles of hind wings 2-celled). Abdomen 11-18, hind 
wing 14{5-18°5 mm. As this wing-pattern seems to be distinct in the Floridan specimens, I think it convenient 
to designate them by the subspecific name Perithemis domitia seminole, subsp. n., from the well-known 
Indian tribe of this region. Seven females; the type from Volusia, May 12 (coll. P. P.C.: 1 9), Enterprise
