Stenaspilates. I am, therefore, holding Hulst's name on this speci- 

 men, representing a species which apparently has as yet received no 

 oilier appellation. 



The complete life history of honestarius has not yet been worked 

 out ; nor indeed has it been worked out in any of our species. 



The larva is described by Mr. A. V Caudell as follows: 



Length, :'."> mm. Head 2.5 nun. wide, strongly bilobed, the lobes li^ht ash-colored 

 above and <>lii usely angled. Inner anterior borders of the Lobes darker, almost fuscous. 

 I i. e lighter, especially the lower half of the triangular clypeus. General color of the 

 body brownish, mottled with longitudinal splashes of a lighter shade. Tubercles 

 black, minute. Hairs microscopic, black. Thoracic legs on outer side concolormis 

 with the body; on the inner surface, lighter. Abdominal legs colored same as the 

 body on the outer surface, i>ut black on the inner sides, and the venter between the 

 anal pair is also black, bordered posteriorly with white. There is an irregular, not 

 prominent, transverse ridge on the twelfth segment. 



The larva fed on wild cherry, and entered the ground on July 10, 

 the imago emerging in the following August. 



Professor Packard states in his Forest Insects that Miss Emily L. 

 Morton raised it commonly on wild cherry, and that those fed on 

 maple, "the usual food plant," died. 



PERO GIGANTEUS, new species.

Expanse, 15 to 51 mm. Head and body pale purplish-gray to 

 reddish-brown, the latter color usually predominant in the female, 

 though not entirely confined to that sex. Antennae yellowish with a 

 white spot at the base of each which are frequently connected by a 

 concolorous line that extends across the superior pari of the front. 

 Ground color of wings whitish-gray with more or less of a yellowish, 

 brownish, or faint purplish cast. Inner line of primaries broad and 

 conspicuous from costa to center of discal cell, thence obsolete to 

 cubitus, Intl reappearing less strongly below this vein and continu- 

 ing with the usual scallops to inner margin. Outer line brown, 

 sharply defined externally but blending with the median shade 

 internally, usually quite strongly sinuous and sometimes forming 

 angles on the veins in the lower part of the wing. Inner area 

 speckled, often profusely, with gray. .Median area with or without 

 speckles and usually filled in with umber-brown (male) or reddish- 

 brown (female) which becomes intense at t he outer line. Outer area 

 with the speckles finer, and forming transverse strigations which, 

 between veins M :1 and Cu 2 near outer line and on inner margin near 

 anal angle, are clustered together in more or less dense clouds.
