CLEAR UNDERWING. 35 T 



brown shininsr chrvsalis is enclosed in a cocoon of wood 

 scrapings woven together with silk. The moth is out in May 

 and June ; and has been found, newly emerged, sitting on 

 stems of poplar in the morning. 



The eastern counties of England appear to be most favoured 

 by this species, but it also occurs northwards to Yorkshire, 

 southwards to Devonshire, and a specimen has been recorded 

 from Rhyl, North Wales. In Scotland, it has been reported 

 from some localities in the south ; Kane states that he has 

 reason to believe that the species occurs in the northern half 

 of Ireland, and that he found caterpillars plentiful in young 

 poplars growing in a marsh near the city of Waterford. 



Lunar Hornet {Trochilhun crabroniformis). 



Another hornet-like moth, best distinguished from that just 

 mentioned by the yellow collar behind the black head (Plate 154, 

 Fig. 7 $ ). The male is rather smaller, but otherwise similar. 



The caterpillar is yellowish white, wdth dark brownish head, 

 and a blackish edged yellow plate on the first ring of the body. 

 It feeds in stems of sallow, willow, and poplar. In late June and 

 through July the moth is on the wing, and may occasionally be 

 seen at rest on leaves or stems of sallow, etc. 



The species, known also as bejnbecifonnis^ Hiibner, is 

 generally distributed throughout England, Wales, and Ireland ; 

 in Scotland its range extends into Perthshire. 



Abroad it seems pretty much confined to Holland, Northern 

 and Central Germany, Austria, and Bohemia. 



Clear Underwing {Sciapteron tabaniformis). 



This species is the Trocheliiwi vespiforme of some British 

 authors, and the ^geria asiliformis of Stephens and others. 



Another English name for it is the Dusky Clearwing, and 

 this refers to the cloudy fore wings.
