TRIFID^. 275 



eggs already noticed were obtained ; and from this time 

 onward one or two specimens have been secured in almost 

 every year, occasionally more. Apparently it is scattered 

 all over the extreme South of England, since there are records 

 from Deal and Lewisham, Kent ; Brighton, Sussex ; Isle of 

 Wight, Hants ; the Isle of Portland, the Chesil Bank, East 

 Studland, Bournemouth, and the Isle of Purbeck, Dorset ; 

 Exeter, Teignmouth, Torquay, Kingsdown, and Lynmouth, 

 Devon ; and one in Cornwall. Besides these, the only 

 capture of which I have any knowledge in England is of a 

 specimen at Crosby, Liverpool ; and my own two specimens 

 in Pembrokeshire seem to complete the list of British 

 occurrences. 



Abroad its range is very wide, through South Europe, with 

 Carniola ; Armenia, Syria, Asia Minor, India, and throughout 

 the Oriental region ; Egypt, Madeira, Northern Africa, and 

 South Africa — where it is very plentiful, comes constantly to 

 light in the houses, and is sent home with every consignment 

 of insects, pinned, papered, or packed in cotton-wool. More- 

 over it is found in both North and South America, and even 

 in the Pacific Ocean at Honolulu. To all appearance it is 

 one of those erratic and migratory species to which hardly 

 any defined range can be ascribed. 



Genus 66. STILBIA. 



Antenna of the male almost naked ; palpi slender ; eyes 

 naked, without lashes ; thorax narrow, smooth, except a 

 small knob of scales at the back ; abdomen rather slender, 

 without crests; fore wings narrow at the base, broader 

 behind, shining ; hind wings thin but very large ; cross-bar 

 rather straight, vein 5 very slender, arising accurately from 

 its middle. Female a little smaller, fore wings more evenly 

 narrow, body hardly stouter. In repose the fore wings 

 partially overlap, and form a very inclined roof. 



We have but one species.
