PSEUDOTHYATYRA CYMATOPHOROIDES, Gue. 
The larva of this species is unknown to me, nor can I find that 
it has been described. The general description of the larvae of the 
genus is given thus by Guenee: Caterpillars smooth, monilifoim 
(that is the transverse sutures between the segments, are deep), 
holding in repose the anal pair of feet away from the plane of the 
body, their last segment elevated as in the Notodontce. Live upon 
rosaceous plants. 
Apatela occidentalis, Grote. 
The larva of this species is of a bluish gray color and sparsely 
covered with whitish hairs more numerous on the sides and near 
the upper surface, a wide slate colored dorsal stripe, in the middle 
of which, extending from the second to the fifth segments, is a pale 
orange line; on the dorsal stripe on each segment from the fifth to 
the eleventh is a nearly round, black velvety patch, in which are set 
four bright spots, one in front and one behind orange, and one on 
each side greenish with a metallic lustre; on each side of the dor¬ 
sal stripe is a cream colored line; below this on the side another of 
a similar color, both growing somewhat indistinct anteriorly and 
posteriorly; a short black curved line extends across the cream 
colored lines commencing at the velvety patches; the sides are more 
or less covered with spots of a dull ochre color, some of which 
form a broken line close to the under surface; also covered with 
whitish more thickly on the sides; on the top of the twelfth seg¬ 
ment is a small black hump; the terminal segment is flattened and 
blackish; underside dull greenish; feet black. Head black, rather 
long, bilobed, somewhat flattened in front, sparsely covered with 
whitish hairs and a few yellow dots on the sides. 
Found on Mountain Ash in the latter part of June, the cocoons 
form about the second week in July and the moths issue the first part 
of August. The second brood has been found during the first part 
of September on Plum, Cherry and Apple, the chrysalis forming in 
the latter part of the same month and the moth appearing toward 
the first of the next June.
