that has disappeared by coalescence with 7. In some species of this 
group vein 8 coalesces with 7 to end of cell, producing the appearance 
of the absence of vein 8. These two groups of Phsegopterids are thus 
essentially Arctian, though apparently showing the Euchromian struc-

Bertholdia was erected by Mr. Schaus in this Journal (IV, 137) with 
type specular is H. S., containing three species. These are superficially 
recognizable by the large triangular vitreous patch on costa, but other 
spectes without this mark must ultimately come in the genus. Mr. 
Schaus has kindly given me a number of specimens of Bertholdia , 
among which I recognize a new form, apparently uncharacterized. 
Bertholdia schausiana, sp. nov. 
Intermediate between specularis and trigona. Primaries lead color, shaded with 
pink more or less, especially toward anal angle, dotted with black. Costa red, ex¬ 
cept at the vitreous patch, where it is yellow. The patch is excavated superiorly be¬ 
tween vein 6 and rosta, produced outward in the interspace 5-6 or simply angled, the 
lower border nearly straight, lightly shaded with yellow, the veins black dotted. The 
shape is most like trigona but distinctly angled in the interspace 5-6 and not pointed 
below. Basal yellow spots absent, or one small one present. Body and hind wings 
as in trigona. Expanse, 33-39 mm -

Gorgonidia, gen. nov. 
Primaries with median vein 4 branched, cross vein of cell slightly concave, & 
from the apex of cell, 7-10 stalked ; secondaries with vein 5 absent, 6 and 7 stalked, 
8 joining the subcostal for over half the length of the cell. Wing long, produced, the 
secondaries small, trigonate. Palpi robust, not reaching vertex of head, first and 
second joints subequal, third minute. Ocelli touching the eye. Male antennae serrate 
ciliate. Two pair of spuis on hind tibiae. 
The male has a stridulating organ on the thorax like that of the 
Asiatic genus Dionychopus, i. e„ Spilosoma (?) nivens Mdnet. of Kirby’s 
catalogue. (See Psyche, VII, 415. ' or description.)
