DESCKIPTION OF A NEW SPECIES OF ANOMALON. 195 



light scales, as in 0. maculatiis and 0. nemorosus. Abdomen 

 with yellowish bands, each embracing two contiguous segments, 

 and connected by a median dorsal yellowish line, so that in pale 

 specimens each segment of the abdomen appears to have a pair 

 of subquadrate dark brown patches. Average length, $ 6'5 mm., 

 ? 5 mm. 



This species occurs abundantly at Aldborough, Suffolk, and 

 has been taken at various places in the London district (Charlton, 

 Dartford, Albert Docks, Lewisham, Camberwell, Chiswick, Stam- 

 ford Hill), and at Kochester and Wyre Forest. 



I believe that Eondani's Culex imlchripalins and G. penicillaris 

 are both synonyms. Theobald introduced C . imlchripalins as British 

 on the strength of some specimens of tliis species taken at the Albert 

 Docks. 



2. 0. vexans, Mg. — Thorax dark brown, uniformly clothed 

 with dark golden-brown scales. Pale bands of abdomen (in 

 female at least) narrowly interrupted at the sides and indented 

 in the middle, so that they appear bilobed. Male genitalia very 

 peculiar, the claspers being forked. Average length, 3- 6 mm., 

 ? 5 mm. 



This species has at present but slender claims to a place in 

 the British list. It has been confused with Thcohaldia morsitans, 

 and probably some of the old records of 0. vexans really refer to 

 that species. In the old CUfton collection in the British Museum 

 were seven specimens of this species, all without locality label — 

 three females unnamed, and two males, two females labelled 

 *' ? calopus, Meig." Apart from these the only British specimens 

 I have seen or heard of are a male and female in the Cambridge 

 Museum, taken at Mildenhall, Suffolk, July, 1894, by Mr. C. G. 

 Lamb. Both these are very much rubbed, and the characteristic 

 abdominal markings of the female removed. 



0. vexans occurs, I believe, in North America under the name of 

 sylvestris, Theo. — variously placed in Culex, Ecculcx, or A'ccles. 

 Theobald's type was said to have the hind claws of the female 

 simple, but most American specimens have them toothed, like the 

 European 0. vexans.
