PERROTIA. By W. Hopp. 
tamatavana. 
roundish spot at the cell-end, distally edged with white, 4 small white spots in the apical portion, a black roundish 
spot below the cell, likewise with lateral white irroration, all being very indistinct. Costal margin whitish. 
Head, thorax, abdomen, and legs scantily clad with whitish-grey and brown thin hairs. Antennae whitish; 
without visible pinnae. The abdominal segments are clothed with bristles beneath the hah’, as in the Megci- 
lopygidae and some Phauclinae. Of the rare species only females are known hitherto, from Cape Town, Grahams- 
town and Natal; the imagines exhibit an unwieldy flight by day, on the slopes of mountains in the Protea 
Region. Nothing is known of the biology. 
2. Genus: I*era*©tia Oberth. 
The only species belonging to this genus was considered by Oberthur to be aMadagassic Megalopygida, 
but Jordan’s recent examination of this insect (1. c. p. 132) proved it to be a Zygaenida, likewise belonging 
to the Phaudinae and allied to the genus Anomoeotes from which, however, it is separated by the thick, relatively 
short antennal pinnae, the thick body, and the veins, particularly the absence of the first radial branch of the 
hindwing (R1 = vein 6) and the long stalk of the costal and subcostal (Sc 2) of the hindwing. The fore wing 
lacks the retinaculum. 
P. tamatavana Obth. has black thin legs, with very hairy femora, on the underside light yellowish-brown. 
Thorax blackish-brown, collar yellowish. Abdomen yellowish-brown, at the anus a small dark brown spot. 
Wings above and beneath reddish-brown. Hindwing somewhat lighter. Only the male is known hitherto 
from the surroundings of Tamatava, Madagascar.
