N0CTUID;E. — HELIOPHOBUS. 189 



Caterpillar greenish, with darker shades : the head and first segment brownish : 

 it feeds on the Saponaria officinalis and other plants: — the imago appears to- 

 wards the end of June, or beginning of July. 



Rare ; four or five specimens have been captured in my presence 

 at Darenth-wood, where I once caught a single specimen : it occurs 

 much more abundantly near Brighton ; and is found in Norfolk 

 and near Dover. " Bottisham." — Rev. L. Jenyns. 



Genus CVIII. — Heliophobus, Boisduval. 



Palpi rather short, stout, porrect, densely squamose, tri-articulate, the terminal 

 joint exposed, but squamose; the basal joint reniform, rather stouter than, 

 and about one-half the length of, the second, which is attenuated at the apex; 

 terminal joint about half as long as the first, elongate-ovate: maxillce very 

 short. AntenncE very strongly bipectinated in the males, the pectinations 

 reaching to the apex, furnished with a few distant bristles in the females : 

 head small, pilose in front ; eyes large, pubescent : thorax stout, crested : wings 

 rather deflexed during repose, the anterior obscurely denticulate on the pos- 

 terior margin, which is somewhat ample : the nervures generally pale; posterior 

 slightly notched on the hinder margin, towards the costa, pale with a darker 

 border ; body rather long, stout, of the male with a large tuft at the apex, of 

 the female rather acute, with a small apical tuft : legs short, robust, ihe femora 

 and tibiae very pilose ; posterior tibice with two pair of long spurs. Larva 

 naked : pupa subterranean. 



The great dissimilarity of the antennae in the sexes of the only 

 two known species of this genus, at once point out their pretensions 

 for generic distinction from Hadena, with which genus all authors 

 but Boisduval have hitherto united them ; however, their very great 

 disparity from the typical species of that genus had long determined 

 me to disunite them therefrom : although the species somewhat re- 

 semble the three last species of Hadena, they may be distinguished 

 with facility by their elongate antennae, — the males having them 

 strongly pectinated, and the females furnished with bristles ; those 

 of the former sex in Hadena being not very long, and more or less 

 ciliated, while those of the latter are simple, — and more especially 

 by the brevity of their maxillae.
