274 LEPIDOPTERA. 



About the actual capture of these specimens at the place 

 stated there is no shadow of a doubt. Mr. Marsh distinctly 

 remembers taking them when looking for Macroglossa horiiby- 

 liforiim, which was flying at flowers of Pedicularis sylvatica ; 

 but, although frequently working the district in subsequent 

 years, he never saw the species again ; and a strenuous eSbrt 

 in the present year (1892), to re-discover it, has only resulted 

 in convincing him, as well as myself, of its total absence at 

 the present time. Under these circumstances it seems un- 

 desirable now to introduce the species to a place in the 

 British list, but rather to record the captures in question as 

 specimens accidentally introduced with plants, or else the 

 result of a very exceptional act of migration. One other 

 .specimen, apparently of the same species, and said to have 

 been captured in Yorkshire, was exhibited by Mr. J. T. 

 Carrington, at a meeting of the South London Entomological 

 and Natural History Society, in January 1890, under the 

 name of SyricMhus Carthami. 



[According to Kirby the larva feeds on Polyyala chamcvhuxus, 

 and the insect in its numerous varieties (in which he includes 

 serratulce, Rambur, fritillum, Hiib., and ccecus, Freyer) occurs 

 in all parts of Eurofie except the north-west, as well as in 

 Northern and Western Asia and North Africa, from May 

 to August, frequenting glades of woods and sunny slopes, 

 and being more plentiful in the mountain districts than in 

 the plains.] 



Genus 2. HESPERIA. 



Antennae with a long club which, in some of the species, is 

 furnished with a terminal hook. Thorax very robust. Fore 

 wings with the hind margins rounded, or even in some species 

 with the curve altered by a very slight approach to angulation 

 below the apex. Hind wings emarginate or indented before 

 the anal angle. Males with a central oblique black streak of 

 raised scales on the fore wings.
