common, but from its swiftness, and trick of hiding close to 

 the ground when indisposed for flight, not very easy to 

 obtain in numbers. There is a record of the capture of a 

 single specimen on Wimbledon Common, near London, in 

 1872. Abroad it is widely distributed throughout Northern, 

 Central, and Southern Europe, and is found in the Ural 

 Mountains. 



Genus 2. DEIOPEIA. 



Antennae simple ; fore wings triangular, narrow at the 

 base, very broad behind ; hind wings broad and ample. 



1. D. pulchella, L. Expanse 1^ to If inch. Fore 

 wings white, with abundant pink and black dots ; hind wings 

 white, with blackish margin. 



Antennae rather short and threadlike, but with the joints 

 notched, furnished with pairs of oblique bristles arising 

 from every joint ; blackish. Head whitish, with the crown 

 ochreous, and the palpi yellow tipped with black ; thorax 

 yellow or yellowish white, with a round black spot on each 

 half of the collar, two on each shoulder-lappet, and three 

 down the middle of the back ; abdomen clear smooth white. 

 Fore wings nearly triangular, very narrow at the base, 

 gradually widening, and very broad behind ; costal and 

 dorsal margins nearly straight ; apex obtuse ; hind margin 

 below it nearly straight, and not very oblique, rounded off at 

 the anal angle. White, ornamented with alternate rows of 

 black and crimson dots. Of the black dots two lie at the 

 base, and are followed by a short curved row answering to 

 the basal line ; beyond are two more rows, answering to the 

 usual first and second transverse lines, both much curved, 

 and the second often partly duplicated ; beyond these in the 

 hinder area is a much straighter line of dots, and a final row 

 lies along the hind margin. Between these black rows are 

 placed the rows of crimson dots, but these are hardly so com- 

 plete, and are much more liable to coalesce and run into
