Occasional Notes on the genus Eupithecia in Co. Fermanagh. 



By J. E. B. ALLEN, M.A. 



I call this paper " Occasional Notes " because, from many causes, 

 my observations have been far from exhaustive. In particular, my 

 absence from this locality every year during August and a great part 

 of September may have caused me to miss some species. 



Fhipit/iecia palchellata. — Occurs sparingly as an imago. I have not 

 worked for the larva. 



E. oblorif/ata. — One specimen only, bred in 1911 from a larva on 

 Senecio jacobaea. 



E. srabiosata. — Both larvffi and imagines, but in small numbers. 



E. pliiinheolata. — Not common. 



E. pi/f/iiiaeata. — One in 1907 and about half-a-dozen in 1911. 



E. satyrata. — Abundant on bogs and mountains. 



E. castif/ata. — Seems to be rather scarce, though I have taken both 

 larva and imago. 



E. «/7'.s/V/»rtr/rt.— About 40 larvffi on Anqelka njlvestris'm September, 

 1910. 



E. virt/a areata. — Very abundant. In May the first brood is to be 

 taken at dusk or beaten from hedges. The larvae are to be beaten 

 from the flowering branches of hawthorn in June and July. The 

 imago occurs again in July and August, and the larva again in the 

 autumn on Senecio jacobaea, S. pabistris, Ani/elica sijlvestrifi, Solidago 

 virt/aiirea, and probably other plants. I have taken it in the garden, 

 once on a rosebud, and once on a cultivated form of daisy. In Sep- 

 tember, 1910, the larvas were very abundant. I took hundreds on 

 ragwort, but a very large proportion of these were stung. Golden-rod 

 is not plentiful here, and I only worked it in one locality, the shore of 

 an island in Lower Lough Erne. The larvae taken there were much 

 less infested than the larvae from ragwort, and produced much larger 

 moths. Of the larvae taken in June and July, some come out as a 

 second brood in July and August of the same summer, some appear 

 with the first brood in the following summer, and I bred one on April 

 24th, 1909, which had lain two winters in the pupa, from June or 

 July, 1907. I am unable to say whether the autumn larva? ever lie 

 over for more than one winter. The list of food-plants given above 

 is certainly incomplete. For instance, the progeny of the golden-rod 

 feeding larvje must find some other food than hawthorn, for there is 

 very little of it growing on the island, where they occur. Similarly
