Typhlocyba NITIDULA. 13^ 



bordered with white. Elytron often shows a faint 

 white annulus on the costa. Legs pale brownish. 



This prettily marked insect is rather uncommon. 

 I found it usually at Haslemere on the alder. I 

 have examples from Albury, Hertfordshire ; and from 

 Huddersfield, Yorkshire. 



Length with wings, 0*16 inch, 4-00 millimetres.

Form rather robust. General colour creamy-white 

 or pale ferruginous-yellow. Head and pronotum spot- 

 less. Scutellum black. Abdomen fusiform,. obscurely 

 ringed or rugose. Elytron sometimes with prominent 

 brown nervures, at other times these are obsolete. A 

 broad black spot runs at the base of the corium, which 

 generally appears also on the clavus. A broad black 

 bar crosses the corium at about one-third from the 

 apex. Eyes reddish brown. Legs all rufous-yellow. 

 All the under side is yellow. 



This insect is liable to variation as to the barrings 

 on the elytra. 



The variety A. Norgueti, Leth., has two-thirds of 

 the base of the elytral membrane filled in with dark 

 brown. 



Sometimes this insect swarms on "broad-leaved 

 elms," but it is uncertain in its appearance. Mr. 

 Edwards captured it also from the Lombardy poplar.
