 ferruginous or ochreous, reticulated, and with 

 distinct darker markings Species 1, 2

 tions, and clouded with fuscous or leaden-coloured 

 markings Species 3 



I . contaminana, Hub. Alis anticis laete stramineis ; brunneo-re-

Head slightly ochreous, or dusky yellow. Face of same colour, 

 but slightly darker. Eyes intense purple brown, with a velvety 

 appearance. Palpi : above and at the sides pale ferruginous ; beneath 

 pale ferruginous at the apex, straw-colour at the base. Antennae 

 fuscous, with the basal and a few succeeding joints above ferru- 

 ginous, the basal joint beneath straw-colour. Thorax and patagia 

 pale ochreous, with a ferruginous tint ; the former with a simple cari- 

 nated ferruginous crest on the vertex. Anterior wings bright straw- 

 colour, strongly and distinctly reticulated with red or ferruginous 

 brown, the reticulation following the venation of the wing; the 

 costal and dorsal margins edged with reddish brown. Near the base 

 is a strong streak angulated in the middle, and sometimes suffused 

 and widened at its extremities; this streak, with a large Y-like 

 mark beyond the middle of the wing, is dull chocolate-colour, with a 

 leaden tinge; the Y-like mark does not always reach the dorsal 

 margin. In fine specimens a few whitish, minute tufts of elevated 

 scales are visible in the centre of the wing. Apical scales ferruginous 

 brown, with paler bases. Cilia shining, pale straw-colour. Pos- 

 terior wings with a shining, pearly appearance, the reticulation at 

 the apex beneath, showing through. Marginal scales slightly grey, 

 with pale bases. Cilia dirty white. Abdomen pale fuscous grey, 

 the caudal tuft pale straw-colour. $ Exp. al. 6| 9^ lin. 



A very common, and at the same time a variable insect ; the 

 variations from the type, as above described, are comprised in 

 the varieties D. ciliana and D. rhombana. 



In D. ciliana the ground-colour of the anterior wings is 

 ferruginous, with the markings dark or chestnut-brown ; but the 

 colours are more or less intense in different specimens. Cilia 

 whitish. 



In D. rhombana the anterior wings are dark ferruginous, 

 merging into fuscous, with a leaden tinge obscurely reticulated 

 and fasciated with umber. Cilia whitish. 



The imago frequents the Whitethorn, and occurs from July to 

 October in tolerable abundance, especially in the metropolitan
