Delucchi (1955 : 89) misinterpreted claviger as a synonym of Stictomischus obscurus 

 (Walker), probably by assuming that the first specimen in Thomson's series of 

 claviger was the type ; but a reference to Thomson's description would immediately 

 have shown that such could not be the case. 



Skeloceras seiunctum Delucchi. Type (? holotype) $, Germany, Thuringia 

 (Schmiedeknecht) , in Naturhistorisches Museum, Vienna. 



Variation in clavigerum is apparently slight. In most females the basal half to 

 two-thirds of the fore femora is fuscous and the mid femora have a dark stripe 

 beneath ; in some British specimens the hind femora are also infuscate basally, 

 whilst I have one British female, which otherwise differs from typical clavigerum 

 only in small details of structure, in which the proximal two-thirds of all the femora 

 is fuscous. The raised sculptured part of the gastral petiole is as long as, or slightly 

 longer than, broad. The median carina of the propodeum may be simple, forked, 

 or irregular.

Biology. Unknown ; imagines have been captured in the field in June and
