A CATALOGUE OP THE LEPIDOPTERA OF IRELAND. 235 



Larentia didymata, L. — Very common and variable. Males 



from the black basaltic cliffs of Antrim near Ballycastle I have 



noticed to be extremely dark, though the females are of the 

 normal pale form. 



Larentia multistrigaria, Haiv. — Very generally distributed 

 throughout Ireland wherever Galium sa.vatile is plentiful. At 

 Howth (where I have taken this species in numbers in the first 

 half of February), and at Clonbrock, &c., the males often show 

 basal and central bands across the fore wing like the female. 

 Co. Dublin and Wicklow ; Westmeath, at Cromlyn (Mrs. B.), 

 Killynon {Miss R.), &c. ; Altadiawan, Co. Tyrone; Co. Derry 

 (C); Ballycastle, and the Belfast hills (IF.). Plentiful in the 

 South of Ireland generally. 



Larentia c^siata, Lang. — Exists throughout the mountain 

 tracts of Ireland, varying much. I have, however, nowhere met 

 with such melanic forms as those from Yorkshire, the grey in- 

 conspicuous type chiefly predominating. Like L. dicltjmata, I 

 have noticed that in rocky localities the species conforms some- 

 what to the tone of the rock formation. In the S.E. of Kerry a 

 very unicolorous grey form is found on the slate formation, but 

 on the limestone cliffs of Clare a very pale one. 



Larentia salicata, Hh. — Local, but existing in all four 

 provinces. In some places, as at Powerscourt, Wicklow, plenti- 

 ful in the May emergence. I have (perhaps accidentally) only 

 met with occasional specimens in the late summer. Besides the 

 pale form with well-defined pattern, sometimes showing a well- 

 defined central band, dark at the borders, but pale round the 

 discoidal spot, there is a dark suffused form (var, unicolorata, 

 Gregson). The former is frequent at Altadiawan, Co. Tyrone, 

 and on the Belfast hills, where the latter also occurs (IF.), and 

 at Clonbrock. Galway {JVallace), Merlin Park, Clonbrock, Kil- 

 cornan (B.), Ardrahan (Miss N.), &c. ; near Crossmolina, Mayo, 

 very common {S. R. F.) ; Markree, Sligo ; near Donegal ; Magil- 

 ligan, Co. Derry, suffused with yellow {Salvage) ; Ballycastle, 

 Larne, &c., Co. Antrim (IF.) ; Churchill and Armagh {J.) ; Castle 

 Bellingham, Co. Louth {Thornhill) ; Co. Tyrone ; Greystones, 

 Arklow, and on the mountain above Powerscourt, Co. Wicklow ; 

 Kinsale, Co. Cork. 



Larentia olivata, Bork. — Apparently very local. Glengarriff', 

 Co. Antrim, numerous (IF.) ; Buncrana, Co. Donegal, a few (C) ; 

 Eockwood, Sligo {R.) ; Clonbrock, Co. Galway, one {R. E. D.) ; 

 Knock Ion, Westmeath, abundant {Miss R.) ; Powerscourt, Co. 

 Wicklow (0. G. B.) ; Bandon, Co. Cork (L.). 



Larentia viridaria, Fb. — Generally distributed and plentiful. 



Emmelesia affinitata, St. — Local and not numerous. I have
