LACE-BUG GENERA — DRAKE AND RUHOFF 47 



The first and so far the only reviser of the Palcarctic species 

 of the genus Copium, Wagner (1954, pp. 200-209) correctly 

 treated Monanthia clavicornis (Linnaeus) (1758) and Copium 

 cornutum Thunberg (1822) as identical species but failed to 

 relegate the latter to synonymy. As indicated under Copium 

 and Monanthia, the type species of these two genera are con- 

 specific, the latter being a junior synonym of the former. For 

 information relative to this synonymy, suppressing of Copium 

 cornutum with C. clavicornis, and resurrection of Dictyla Stal 

 from synonymy to hold almost all of the species included in 

 Monanthia, see discussions under Copium, Dictyla, Monanthia, 

 and Octacysta. Dr. W. E. China, in personal correspondence, 

 states that there are two specimens of tingids under the name 

 "Cimex clavicornis L." in the Linnacan Collection at the Lin- 

 naean Society of London, Burlington House, Picadilly, and that 

 one, in Linnaeus' handwriting, is labeled "Tingis cardui Linn." 

 and the other (without label) is Acalypta carinata (Panzer). 

 The specimen bearing the label with C. clavicornis L. is the 

 thistle tingid that Linnaeus described as C. cardui and it agrees 

 with the original description of cardui. These are plainly self- 

 evident errors made by others in handling the Linnaean specimens 

 during the past two centuries and need no further comments.
