Halticoptera patellana (Dalman), sensu Thomson 



? Diplolepis Patellana Dalman, 1818 : 80-81 [$]. 



Phagonia flavicornis Curtis, 1832 : folio 427 (? nee Halticoptera flavicornis Spinola, 1811). 



Pachylarthrus smaragdinus (Curtis) Walker, 1833 : 457, " ? $ " [nec$]. 



Miscogaster Aeratus Walker, 1839 : 202 " <j> " [recte <$], syn. n. 



Ormocerus Pisuthrus Walker, 1839 : 207, 9, syn. n. 



Halticoptera patellana (Dalman) Thomson, 1876a : 246, <J $. 



Type material. Diplolepis patellana Dalman. I could not find any specimens in 

 Dalman's collection. The males of most of the species mentioned in the present 

 paper are ruled out because they disagree with Dalman's description ; the only 

 males which agree well are those of smaragdina (Curtis) and patellana (Dalman) 

 sensu Thomson, of which the latter seems to agree best. Thomson is more likely 

 than anyone else to have seen the type (possibly now misplaced or lost). That he 

 was familiar with Dalman's material seems clear from the fact that he used Dalman 

 manuscript names for other species (e.g., festiva, brevicornis and laevigata). Peck 

 (1963 : 623) has used patellana as the valid name for the species which I call cir cuius 

 (Walker) in the present work. I do not know his reasons for this usage ; my remarks 

 above will show that it is unlikely to be correct. 



Miscogaster aeratus Walker. One male, LECTOTYPE, labelled " Aeratus " in 

 Walker's handwriting. 



Ormocerus pisuthrus Walker. One female, LECTOTYPE, bearing a Waterhouse 

 label, also another in the handwriting of C. Ferriere " Halticoptera sp. $ ". 



Britain, Sweden ; probably widely distributed in Europe. 



Biology. Reared in England from Spilographa zoe (Mg.) (Dipt., Trypetidae) on 

 Senecio, and from an undetermined host on bracken (Pteridium aquilinum L.) 

 [A. H. Hamm). Jansson (1952 : 5) recorded as hosts in Sweden Agromyza reptans 

 Fin., Phytomyza lappae, R.-D. [=lappina Gour.], Liriomyza congesta (Becker), 

 and Phytomyza sedicola Hering. In Britain the species is commonest where bracken 

 occurs. Imagines June-August. 



Halticoptera laevigata Thomson 



Halticoptera laevigata (Dalmas MS.) Thomson, 1876a : 253, $. 

 Halticoptera levigata Dalla Torre, 1898 : 198 (emendation). 



Type material. Syntypes, 8 specimens. I have not yet selected a lectotype. 



Britain, Sweden, Germany ; uncommon. 



The characters by which the hitherto undescribed male may be recognized are 

 given in my key to males (q.v.). 



Biology. I have seen males reared in Germany, Berlin-Dahlem, 5-11.iii.1954, 

 from Anomoia (—Phagocarpus) permunda (Harris) (Dipt., Trypetidae) in fruits of 

 Cotoneaster multiflora Bge. (Prof. E. M. Hering) ; and both sexes reared in England 

 (Surrey, Ranmore Common, 17.vii.1939) from the same host on Crataegus monogyna 

 L. (M. Niblett). Imagines (in Britain) occur in the field July-October.
