NATADA. By H. G. Dyar |. 
1123 
P. ceres Drc. (165 e). Greyish brown with a broad blackish submarginal shadow which is incurved ceres. 
outside in the middle; a whitish inner-marginal area extends almost to the median vein, and a light oblique 
strigiform spot extends from the base of the inner margin upwards outside. Hindwing dark greyish brown, 
fringe light. Expanse of wings: 20 — 24, $ 24—26 mm. Mexico, Guatemala; S. Salvador. 
20. Genus: J^Tatada Wkr. 
Antennae of bipectinate almost to the tips, the obliquely upturned truncate palpi project beyond 
the frons. Veins 2 and 3 of forewing arise separately, vein 7 arises from vein 6 remote from the cell. The genus 
contains a great number of mostly larger species of a robust build. Bombycocera Fldr. and Rhinaxima Bar are 
synonyms. As the species are often difficult to distinguish, we supply again an analytical table. 
Type: N. rufescens Wkr.
