The serrated appearance on the underside of the anterior 

 legs is, I believe, unnoticed by Authors; the tibite are also 

 bristly, and the spurs long and slender. 



This is a local insect, and used to be reared by the late 

 Duchess of Pordand, wiio first found it in the Isle of Port- 

 land, and it has since been met with on the sea-shore of Ire- 

 land the end of August; but little of its history was known 

 until that indefatigable and zealous Naturalist Capt. Blomer 

 discovered its locality, and to him I am indebted for the fol- 

 lowing observations and the figure of the Larva. 



" It was by mere accident I observed the Caterpillars feeding 

 on the Galium xjenan, or Yellow Lady's Bed -straw, in crossing 

 a level spot in a hollow between some sand-hills at Appledore 

 Burrows, where that plant predominated, and where it was al- 

 most covered over with sand, except here and there a little 

 appearing above it: in the course of half an hour I collected 

 near 40 larvae, mostly full grown, in the space of a hundred 

 yards in circumference, when they disappeared and I never 

 could find another either in that or the following season: this 

 occurred the end of May 1 825, on a dark showery day. Some 

 3'ears subsequently, at the same period of the year, at Dawlish 

 Warren, I observed a profusion of the Galium amongst the 

 sand-hills, which convinced me the Caterpillars were to be 

 found under the sand, and the next day I took my small flower 

 garden-rake, and raking the sand, I soon succeeded in finding 

 them ; they lay about an inch under the sand. By the same 

 means I found plenty of the larvae of N. vitta and valligera, 

 but only where short grass abounded, on the roots of which 

 they feed; also the larva of iV. Sagittifcra on the leaves of the 

 Henbane, or under the sand, chiefly beneath the leaves. I 

 conclude the larva of N.i^t'cEcox only feeds at night, except on 

 dark stormy days, as was the case on the day I first found them 

 feeding. I reared the larva? in a box covered three inches 

 deep with the sand in which I found them, and the moths 

 were produced the following August." 



The other species I have included in this group forms the 

 Genus Lycophotia Hiib., and Scotophila Steph. 

 LI. PoRPHYREA Hub. Noct, pi. 19./. 93. — picta Fab. — Ericaj 

 Do7i. I0.pl. 360. f. 1. 



End of July, heaths, Yorkshire ; Norfolk ; Kent ; Birch- 

 wood, the New Forest, &c. 



The Caterpillar feeds on the Ericae, especially E. cinerca 

 (pi. 35.); according to Hiibner and M. Duponchel it forms 

 a cocoon of earth and dry leaves at the foot of the plant on 

 which it fed. 



Galium verum having been figured in pi. 317, and authors 

 stating that the Larva of A. pracox feeds also on the Sonchus 

 oleraceus (Common Sow-thistle) it is added to our Plate.
