also the longitudinal costulae situated in the panels of the median area are less 

 regular and usually do not reach the transverse costula.

Habrocytus glabriculus Thomson 



(Text-figs. 374, 400, 411) 



Habrocytus glabriculus Thomson, 1878 : 113-114, $. 



Type material. Syntypes, 3 £. LECTOTYPE labelled " Lp. in. " ; " Bhn " ; 

 and bearing my lectotype label. I have not seen any additional material.

Biology. Unknown. 



Habrocytus sp. indet. H 



England : Surrey, Ashstead Common, $ $ em. vii.1963 from stem galls on 

 Mugwort {Artemisia vulgaris L.) (A. F. Amsden) ; Oxfordshire, Thatcham Reeds, 

 near Newbury, 28.viii.1964, $$ on the same plant species {Graham). 



This is very near to glabriculus Thomson, but not I think within the range of 

 variation of that species. 



Habrocytus ? lactucae (Erdos & Szelenyi) comb. n. 



? Cecidostiba lactucae Erdos & Szelenyi, in Erdos, 1953 : 228, 231-232, <J $. 



Type material. Syntypes, Hungary, Heves, Atany, 15-17. vii. 1935, from 

 inflorescences of Lactuca sativa L., with Trypanea amoena Frauenf. ; Kalocsa, 

 24-25.vii.1946, 13-17. vii. 1948 together with the host, in Hungarian National 

 Museum and in the Phytopathological Institute, Budapest, also in the collections of 

 Novitzky and Ferriere. I have seen some specimens, said to be syntypes, from the 

 Hungarian National Museum, but these do not seem to fit the description well. 

 Before selecting a lectotype it will be necessary to examine all the syntypes, since 

 the possibility that the series is a mixed one cannot be overlooked. 



Hungary. 



Biology. Parasite of Trypanea amoena (Frauenf.) (Dipt., Trypetidae).
