PRACTICAL HINTS RELATING TO THE EUPITHECIIDS. 181 



June, resting in the well-known Eupitheciid manner, on any flat object 

 near the foodplant, or hidden among the latter. It is rarely to be disturbed 

 during the daytime, and is not at all frequently seen at dusk, when the 

 species is on the wing, among its foodplant. Altogether, in this 

 stage, it is a rather retiring insect. 



The long slender larva of Eiqyithecia centaureata feeds from July 

 to September on a variety of foodplants, of which the flowers of 

 Senecio jacohaea, Solidaffo virc/aiirea, and Eupatoriw)i cannahimun appear 

 to be the most usual, although the species of ragwort, yarrow, knap- 

 weed, scabious, Pimpinella saxifraf/a, etc., have been recorded. One of 

 the easiest modes of collecting the larvfe is to beat the flowers against 

 the side of an umbrella, when the larvfe fall in, usually with those of 

 two or three other species. 



The imago of Eupithecia centaureata may be found throughout 

 the summer (partially double -brooded) resting on fences, walls, etc., in 

 the neighbourhood of woods and gardens, as well as on the stems and 

 leaves of plants, the white wings making it conspicuous. In the 

 evening it flies over the flowers that will serve its larva for food, and is 

 particularly attracted by light. 



The larva of Eupithecia sucoenturiata is found in September and 

 October on Artemisia vulgaris, feeding at night on the upper surface 

 of the leaves ; it has also been reported upon A. maritima and tansy. 

 In the daytime it hides away among the dead leaves at the bottom of 

 the plant. 



The imago of Eupithecia succenturiata is to be found in July and 

 August, but during the day hides most successfully among its food- 

 plant ; at dusk, however, it flies about the clumps of Artemisia, and 

 after dark may be found with a lantern, crawling about the leaves 

 thereof. 



The larva of Eupithecia subfulvata is to be found in September and 

 October on Achillea millefolium, on the flowers, seeds, and leaves of 

 which it feeds, chiefly by night ; during the day it rests usually along 

 the midrib of a leaf, or along a stem, upon which its colour well 

 protects it. It has also been reported upon Tanacetum rulf/are, and in 

 confinement will eat garden chrysanthemum. 



The imago of Eupithecia subfulvata is to be found in July and 

 August, it is on the wing at dusk, and may, a little later, by the aid of 

 a lantern, be found flying around, or settled upon the leaves of flowers 

 of ragwort. It is rarely to be disturbed during the day, although 

 occasionally to be seen resting on a paling or other object adjacent to 

 its foodplant. It occasionally comes to light. 



The long, slender, and variably coloured larva of Eupithecia 

 subumbrata feeds from July to September on the flowers of a variety of 

 plants, of which Apargia hispida, Crepis tar axi folia, Scabiosa, Centaurea, 

 Snlidago, Globularia, Gentiana, Jasione, Origanmn, Hypericum, 

 Chrysanthemum , Euphrasia, Campamda, Pimpinella, and others, have 

 been recorded. 



The imago of Eupithecia subumbrata is on the wing in June ; hides 

 by day among the bushes on the outskirts of woods bordering downs, 

 etc., from which it may readily be beaten in the afternoon. At dusk 

 it flies fairly actively, and is to be found on flowery banks, in 

 rough fields, on the borders of heaths, as well as the chalk-downs, on 

 which it is fairly abundant in Kent,
