THE MACRO -LEPIDOPTERA OF COUNTY TYRONE. 219 



The arrangement and nomenclature are based on South's 

 ' Butterdies and Moths of the British Isles.' 



PiHOPALOCERA. 



Pieri)ue. 



Pieris brassicce, L. — Fairly abundant, but the least common 

 of the local species of Pieris ; as a rule single-brooded, several 

 females with spots on fore wings almost connected by a suffusion 

 of dark scales. 



. Pieris rap(e,Ij. — Abundant generally in the cultivated districts, 

 some of the males of the spring brood almost spotless, and 

 many of the females of the summer emergence are yellowish, and 

 often with spots in disc of lower wings, and upper wings suffused 

 with dark scales up to discal spots. 



Pieris napi, L. — Very abundant, the males of the spring 

 brood varying from an immaculate form to one with well-marked 

 discal spot ; some of the females very faintly marked ; others 

 have the spots blurred into one another and the fore wings almost 

 all suffused with grey scales, and the nerves of the hind wings 

 strongly marked in grey. In the summer brood males with an 

 additional spot on fore wings are frequent ; many of the females 

 have the spots and inner marginal dashes of a burnished appear- 

 ance, and suffused forms are darker than in the spring brood. 

 In both emergences pale primrose and yellow forms are not un- 

 common ; one example of a dull ochre yellow with base of wings 

 darker taken in the Lough Fea district, August, 1907. A dwarf 

 form is common ;' smallest specimen, a female (yellow), measures 

 30 mm. (centre of thorax to apex x 2). 



Euchlo'e cardamines, L. — Almost as abundant as the preceding 

 species; largest example, a male, 51 mm.; a small form is also 

 frequent, smallest specimen taken, 29 mm. Earliest date April 

 20tb, 1918. The following aberrations have occurred locally : 

 .SH//»r^orfuato, Keynes ; citronea,^\\ee\&\: ; ochrea, Tutt ; caulo- 

 tihsticta, Williams; radiata, Wms., and marfjinata, mihi. 



yymplialidce. 



Aglais urticce, L. — Generally abundant, banded forms ap- 

 proaching var. polaris sometimes not uncommon ; one specimen 

 with chalky-blue apex and hind wings without blue crescents, 

 captured at Lough Neagh. 



Vanessa io, L. — Abundant of late years in this district ; 

 specimens with a blue spot under the " eye " on the hind wings 

 are common — ab. cyanosticta, Kaynor. 



Euvanessa antiopa, L. — One seen near Trillick by Piev. S. L. 

 Brakey (K.). Some years ago I was shown an example in a 

 collection taken at Piockdale, near Cookstown, in August, 190-1.
