I9I7- Johnson. — Lisscnoia hasalis Brischkc in Ireland. 83 



follows : — " Nii^ra ; apicc mandibnlarnm et ch'pci rufesccnte, 

 sligmatc pict-o-iiigro \cl dilute-fusco, radicc ct squamula 

 (maris puncto ante alas) albido-flavis (feminae squamula 

 testacea) : pcdibus rufis, tarsis posticis nigris (maris basi 

 tibiarum flava)." At a later date, in 1880,^ he varied 

 this description slightly as follows : — " Nigra ; clypeo 

 rufescente, stigmate nigro, radice et squamula (in mare 

 puncto ante alas) flavis ; pedibus rufis, tarsis posticis nigris 

 (in mare basi tibiarum flava)." 



The male of L. hasalis differs from that of L. sulphiirifera 

 in having the head not narrowed behind the eyes and 

 black except the rufescent clypeus, also in the narrow 

 whitish or flavous band at the base of the tibiae. I have 

 three males all captured here, and in one the spot before 

 the wings is large and triangular, in a second it is 

 small and circular, w'hile in the third it is altogether 

 wanting. The female which I took differs from that 

 of L. snlphurifera in the following points : — the head 

 is not narrowed behind the eyes, the apical half of the 

 clypeus is very pale, almost white, the basal half black, 

 the palpi fuscous, all the coxae black, the trochanters 

 black at base, red at apex, stigma black, radius and tegulae 

 pale, hind tarsi light fuscous. 



Brischke says that it has been bred from Hadena 

 suffnruncida (which is also a host of L. sulphiirifera) and 

 Tapinostola elymi. 



He describes the cocoon as cylindrical, thinly covered, 

 glittering, brownish-white or dark-brown. He records the 

 insect from North Germany, and Mr. Roman tells me that he 

 has met with it in Sweden. It has not been hitherto met 

 with in the British Isles, and I have much pleasure in 

 adding this species to our Irish fauna. 



I wish to thank Mr. Claude Morley, F.E.S., and Mr. R. 

 Lloyd Praeger, M.R.I. A., for their very kind help in 

 obtaining for me copies of Brischke 's descriptions of the 

 species, which I could not have obtained otherwise as I 

 am not within reach of a library of entomological w^orks.
