318 NEUROPTERA. 
“ Einige (2) 2 zeigen eine sehr starke Ausbreitung” &c., and of one of which he has 
kindly sent me a photograph. I am inclined to regard all these as connecting-forms 
between iris and tenera (cf. the Amatitlan female described under iris, iii., page 314). 
RHODOPYGIA. 
Rhodopygia, Kirby, Trans. Zool. Soc. Lond. xii. pp. 265, 299 (1889) *; Cat. Odon. p. 34 (1890) *. 
Only one species of this genus has hitherto been recognized!?. JI can distinguish 
three different but closely allied forms in the material before me. As more numerous 
specimens may show them to intergrade, I give diagnoses of all three, although but 
one, hinei, is known from our present fauna. 
[Wings with one row of cells between subnodal sector and supplementary sector 
next below, abdomen stout (e. g. segment 4 is 2-24 times as long as wide at 
base) ; wings pale brown from base outward to triangle behind the post-costal 
vein of front wing, to two or three cells beyond the triangle on hind wing,

next below. 
Abdomen stout, nearly as in cardinalis ; front wing with a slight, ill-defined trace 
of very pale brown at base hardly reaching as far as arculus; hind wing with 
veins and veinlets behind the postcostal, from base to level of posterior angle 
of triangle, bordered with pale brown, leaving the centres of the cells clear or 
nearly so; hind wing with five rows of cells between A; and the anal “ angle,” 
outer branch of hamule moderately produced; ? unknown. ¢, abdomen 31,

[Abdomen slender (e. g. segment 4 is 4, J, or 33, 9, times as long as wide at 
base); front wing with a slight yellow basal tinge in subcostal and submedian 
spaces reaching out not half-way to submedian cross-vein; hind wing with 
a basal brownish-yellow spot in subcostal space half-way to first ante- 
cubital, in submedian space to cross-vein, back to 2-3 cells beyond apex of 
membranule, five to four rows of cells between A; and the anal “ angle,” 
outer branch of hamule of male more produced laterally than in the preceding 
two species. Abdomen, ¢ ?, 83°5-37; hind wing, ¢ 36°5-39, 2? 38°5-41;
