30 SMITHSONIAN MISCELLANEOUS COLLECTIONS VOL. 73 



theoretical arguments exist on both sides. Hence, 

 rigidly construed, this designation or alleged designa- 

 tion might perhaps best be tabled. 



1829: C. lectularius is on the preferred list under 

 (j) as a non-exotic species, when compared with the 

 following 6 of the 8 remaining original species (not 

 mentioned above in C) of AcantJiia; A. crassipes 

 (Dresden) ; A. lunata (India) ; A. rhomhea (Africa) ; 

 A. serrata (hab. unknown) ; A. serratulae (England) ; 

 A. umhraculata (Hafniae). 



1829: Acanthia clavicornis, the one remaining origi- 

 nal species of Acanthia which comes into theoretical 

 competition has nothing (under Art. 30) to give it 

 preference over A. lectularia. 



E. "Rigidly construed" (Art. 30g), it is not clear that 

 Girault (1905, 61, 117) designates the genotype. 



F. " Rigidly construed " (Art. 30g), the following refer- 

 ences are undebatably definite designations of genotype. 



1904: C. lectularius by: Kirkaldy, 1904, 465; 

 1905. — Reuter, 1908, 27. — Castellani & Chalmers, 191 3, 

 637; 1920, 763. — Van Duzee, 1917, 285. 



G. Conclusion. — C. lectularius was the first and only 

 original species of Clinocoris definitely designated as type 

 of Clinocoris in harmony with Art. 30 and this designation 

 is not subject to change. 



4. Klinophilos Kirkaldy, i8c)g=Clinophilus Blanford, 1903. 

 1899: lectularius type by monotypy (Art. 30c). 

 As soon as one departs from the foregoing citations to which the 

 Rules can be strictly applied one encounters citations that are subject 

 to interpretations that are diametrically opposed to each other and 

 one becomes involved in the uncertainties of elimination, retransfer, 

 and reeliminations, and in the vagaries involved in the citation of a 

 single species as example. 



Accordingly, the Secretary recommends that the Commission adopt 

 as its Opinion the following : 



I. On basis of the premises before the Commission, the com- 

 mon bed-bug of Europe, Cimex lectularius Linn., 1758, is geno- 

 type for Cimex Linn., 1758, Acanthia Fabr., 1775, Clinocoris 

 Petersson or Fallen, 1829, and Klinophilos Kirkaldy, 1899 

 (= Clinophilus Blanford. 1903), and its proper designation 

 under the rules is Cimex lectularius.
