R. abdomirsaria Barnes <£■ Me. D. (= lixaria Grossb., nec Guen.) perhaps scarcely belongs to this group, 
as the abdominal pattern is somewhat different; indeed the short palpus in both sexes may necessitate its 
removal to Neynoria. Antenna of $ narrowly pectinate. Face reddish, in the centre green, at edges with white 
markings nearly as in cosmeta; abdomen with the dorsal spots creamy, confluent into a broad line, not edged 
with red; the dark cell-dots small, but distinct, lines faint, antemedian present on both wings, postmedian 
nearly parallel with termen; terminal red line distinct, with minute white dots at the veins; fringes tinged 
with yellow, only at apex of forewing with reddish. Expanse 18 mm. (<$), 24 mm. ($). Florida. 
R. associaria Barnes Me. D. (= extremaria Grossb., nec Walk.). Very similar to abdominaria, but 
with the palpus ($) much longer, cell-dots fainter, obsolete beneath, terminal line with larger white vein-dots, 
hindwing and its postmedian line more angled in the middle. Florida, founded on a single $ taken at Fort 
Myers in April. 
R. catachloa Hulst seems to be another very lixaria- like species, palpus less strong, hindwing more 
regularly rounded, cell-dots smaller, lines perhaps more markedly dentate, but not very strong, vertex with 
broader red band. I have, however, only seen one specimen. Florida. 
R. texana Hulst perhaps belongs in section B, as irregularia Barnes & Me. D. is said to be “apparently 
related” to it. Face reddish; abdomen above green, with rather large, pure white spot on each segment; wings 
clear green, regularly striated with white, cell-dots and marginal line prominent, red-brown, the white lines 
weak, the postmedian strongly wavy; fringes white, with red spots at ends of veins. Hindwing with distal 
margin somewhat wavy. Texas. 
R. knobelaria Gassino is said to resemble texana, but the abdominal white spots, which are present 
on every segment except the 2nd, though growing smaller and weaker posteriorly, are encircled with red; 
the red face has white spots against the antennae; the postmedian line is crenulate. Palpus moderate, terminal 
joint very small. Arkansas. 
R. rubrolinearia Pack. (= rubrolineata Pack.) (3d). A rather small species, with the white lines 
distinct on both wings, but slender, the red terminal line very slender, the glossy whitish fringes with a 
creamy or sometimes greenish suffusion and with the reddish dots at vein-ends small and generally very faint. 
The white spots of the abdomen in the examples before me with ill-defined reddish circumscription (not men¬ 
tioned by Packard). — Larva on Myrica cerifera, chocolate-brown, with lateral jirotuberances of more even 
development throughout the abdomen (except anal segment) than in degener, directed more cephalad. Dis¬ 
tributed from Pennsylvania to Florida. 
R. festaria Hulst (3 b). More strigulated with white than any of the preceding, otherwise very similar 
to rubrolinearia, but with the ajDex of the forewing slightly more acute, the red terminal line generally stronger, 
the postmedian of the hindwing less bent. Arizona. , 
R. obliqua Hulst. Palpus of £ long. Wings bright green, not strigulated with white, the white lines of 
the forewing broad, straight, the antemedian at least as far from base at hindmargin as at costa, the post¬ 
median parallel with termen, hindwing with postmedian line somewhat bent, both wings with terminal red 
line. The name-typical form has no cell-dots and occurs in Colorado in August, therefore probably a second 
generation of —• form, bellonaria Streck., which is larger, with distinct dark cell-dots and is found in the same 
State in May and June. 
R. manostigma Dyar (5 a). Expanse 25 mm. Face purple. Abdomen above green, the white spots 
large, red-ringed. Wings with the lines reduced to white vein-dots, antemedian of forewing curved, post¬ 
median sinuous, weakly continued on hindwing; cell-sjiot of fore wing enlarged, round, that of the hindwing 
punctiform; terminal line red; fringe white. Mexico: Misantla. 
R. sordifrons sy. n. Expanse 30 mm. Distinguishable from the two following species in that the face 
is dull, rather dark purple-brown, only with green dots at the upper and white ones at the lower corners, 
the antennal pectinations shorter, their length decidedly less than diameter of shaft. Abdomen with first white 
spot rather large, very slightly ringed with red, those on segments 3 and 4 small, not ringed, one on segment 2 
indicated, but weak. Cell-dots larger than in gortaria (3 e) from the same locality, hindwing slightly narrower, 
with the 1st median vein longer stalked, fringes rather strongly red-spotted at ends of veins. Alto da Serra, 
Sao Paulo, April 1923 (R. Spitz), type in Mus. Tring. 
R. viridicincta Schaus. “Face buff” (discoloured from green, its colour in the next 9 species). Abdominal 
white spots not ringed with red. Cell-dots black, shaded with buff; postmedian consisting of white dots which 
are connected by lunules; an antemedian present on fore wing only; terminal line brown, with faint yellow 
spots on veins. "Expanse 20 mm.” S.E. Brazil: Castro. A larger specimen from the same locality has the face 
similarly discoloured, one from Rio Grande do Sul has it green.
