Boml7jx crenosa, IliibTicr, Bomb., t. 4, f. 12. 



This species has the fore wings broad, and witliout a lobe on the liind margin, ashy-grey, with two brownish- 

 bhack crenated streaks, and two bars of brown, one near the base and another in tlie middle, on which is a 

 yellowish stigma ; the cilia is alternately dark and light ; the hind wings pale, with two dusky fascise terminating 

 near the anal angle in a slightly darker jiatch. 



The caterpillar is found in August on the black poplar, and resembles that of Pterostoma palpina : it is pea- 

 green, with dorsal and lateral pale stripes. Discovered by Mr. H. Doubleday in Ongar-park "Wood, Essex, 

 in June, 1839, and again found there in June, 1841. 



PTILOPIIORA*, STEPHE.VS. (NOTODONTA, pars, Boisduvai,.) 



This genus is at once distinguished by the singularly feathered antennas of the males, by the fore wings 

 which are sub-pubescent and pilose, the posterior margin angulated with hair near the base ; the space occupied 

 by the branches of the median vein very broad, the margin itself between these branches being very slightly 

 emarginated ; the palpi small, and nt)t porrected ; the abdomen rather short ; the caterpillars smooth, and without 

 dorsal or sub.apical tubercles. The antenna3 of the females are slightly serrated. 



SPECIES 1.— PTILOPHORA PLUMIGERA. Plate XIV., Fig. 18, 19. 



Phal. (Bomb.) variegata, Villars ; Stephens, 111. 2, pi. 14, fig. I 

 (I'tiloph. plum.) ; Wood, Ind. Ent. pi. 6, f. ,33. 



SvNONYMEs. — Bomlii/.r plumigera, Wicn. Verz.; Fabricius ; 

 lliibner ; Esper ; Ocliscnbcinier ; Godart; Boisduval (Notod. pi.) ; 

 Curtis, pi. ;i28 (Ptiloph. plumig.). 



This curious species measures from 1+ to Ij inch in expanse. The body and fore wings are of a reddish 

 ochre colour, glossed with pale purple, a slight obsolete blotch near the base,' an arcuated stripe beyond the 

 middle, and the outer 'margin being paler ; the antennse brown ; the hind wings have a rosy grey tinge, with a 

 very indistinct fascia across the middle. In the female the colour of the fore wings is still more uniform. 



The caterpillar is of a greenish colour, with a leaden dorsal stripe, and several pale lateral ones. It feeds on 

 the maple, sallow, and birch in Jlay, and the moth appears in October and November. It is a rare species, but 

 is occasionally found, especially in the larva state, in Darenth and Birch Woods. 



* From the Greek, in allusion to the soft feathery antenna borne by the males. The specific name plumigera indicates the same peculiarity, 

 but as it is improper to change specific names without absolute necessity requires it, it would have been more correct to have selected a generic 

 name of a different signification. It is equally incorrect, in order to remedy the evil, to adopt Villars's more recent specific name variegata for 

 tlie typical species.
