 Lamprotatus simillimus Delucchi, 1955 : 10, 14, $. 



I have not seen the type of this species but hope I have interpreted it correctly. 

 Type (? holotype) $, Austria, Bisamberg near Vienna, in Naturhistorisches Museum, 

 Vienna. 



Britain, Austria. In Britain it is locally common and occurs on the foliage 

 and catkins of Salix spp. (cinerea L., aurita L., repens L., etc.) in spring and early 

 summer (imagines April-June). 



Biology. Unknown.

 iv.1949-1950 (S. Novitzky), in Naturhistorisches Museum, Vienna (not seen).

I am adopting the name pschorni for a species in which the antennal pedicellus of 

 the male (Text-fig. 184) is enormously swollen. Dr. Boucek has specimens which 

 he showed to Dr. Delucchi, who thought they belonged to pschorni. The original 

 description does not, however, emphasize the extremely large pedicellus. I had 

 originally considered the species under discussion to be new ; it does not belong to 

 Telepsogos (=Seladerma) but to Lamprotatus. 



SKELOCERAS Delucchi 



Skeloceras Delucchi, 1953a : 216. Type-species S. seiunctum Delucchi, by original designation. 

 Skeloceras Delucchi, 1955 : 6, 20-30. 

 Skeloceras Delucchi ; Kamijo, i960 : 37-41. 

 Skeloceras Delucchi ; Peck et al., 1964 : 38. 



This genus differs from Lamprotatus Westwood only in having the first segment of 

 the clava separated from the others by a deep constriction, so that the funicle has 

 7 segments. However, this character is easily seen [though rather less obvious 

 in socium (Zett.)] and results in a very natural division of the species. 



Kamijo (i960) has given a very good account of the Japanese species of this genus.
