20 SMITHSONIAN MISCELLANEOUS COLLECTIONS VOL. 73 



(* Cuvier, 1798a, 574-575 (Tableau elementaire de I'histoire naturelle des 

 animaux) says : 



Les punaises (Cimex) 

 On les divise en 



a. Acanthies .... (Mentions only "C. Icctularius.") 



b. Punaises proprement dites. (Cimex Fabr.) (4 sp., lineatus, 

 haemorrhoidalis, olcraccus, ornatus.) 



c. Corees. (Coreus Fabr.). (Mentions only marginatus.) 



d. Lygees. (Lygacus Fabr.). (2 sp.) 



e. Gerres. (G err is Fabr.) 



f. Hydrometre. (Hydrometra Latr.) (Mentions only stagnornm.) 



g. Reduves. (Reduvins.) (Mentions only personatus.) 



(* The question arises whether the expression, " Punaises proprement dites 

 {Cimex Fabr.)," when 4 species are cited, constitutes a restriction that affects 

 the type designation. The Secretary is inclined to the view that even if this 

 point were conceded, the type is not designated thereby either for Acanthia 

 or for Cimex, and that while it might have been better under the circumstances 

 to follow this division subsequent to 1798, we cannot alter the fact that this 

 course was not uniformly followed. We must take the facts as they exist, 

 not as they should or might have been.) 



For the next few years we find the species in ever shifting positions, none 

 of which can really be accepted if we view elimination as a legitimate pro- 

 cess in limiting a generic concept. 



Schellenburg in 1800 (Cimicum Helvetiae Genus, pp. 5, 6, 15, 16) in a mono- 

 graph of the Cimicidae has both genera Cimex and Acanthia, and places 

 lectularia in Acanthia (*but does not designate types). 



(* Lamarck, i8oia (Syst. anim. sans vertebres, pp. 293-294) adopts Cimex 

 Linn, as genus, which he divides as follows : 



" Corps ovale ou arrondi. (Acanth. Fab.) 



"Cimex lectularius. Lin. Acanthia lectu — (p. 294) laria. Fab. Ent. 4, p. 67. 

 Geoff, ins. i, p. 434, n. i. La punaise des lits. 



" Get insecte incommode et puant, n'a ni ailes ni elytres par un avortement 

 qui se perpetue, et propage dans un etat qui ressemble a celui de larve. Nean- 

 moins sa classe et son genre sont determines par la consideration de ses 

 congeneres. 



" Corps oblong, un peu etroit. (Ligaei, Fab.) 



'' Cimex equestris. Lin. Ligaeus cquestris. Fab. ent. 4, p. 147. Climex. Geoff, 

 ins. I, p. 442, no. 14.") 



(* On page viii, Lamarck says : " Pour faire connoitre d'une manniere cer- 

 taine les genres dont je donne ici les caracteres, j'ai cite sous chacun d'eux 

 une espece connue, ou tres rarement plusiers, et j'y ai joint quelques synonymes 

 que je puis certifier; cela suffit pour me faire entendre.") 



(*Thus while Lamarck clearly intended C. lectularius to be considered as a 

 Citnex, he recognized two subgroups {Acanthia and Lygaeus), placing C. lectu- 

 larius in the subgroup Acanthia. If his remarks on page viii (see above) are 

 to be interpreted as definite designation of genotypes for the genera in which 

 only one species is cited, it would appear that lectularius is here designated 

 type of Acanthia. Since, however, he did not name one of his subgroups as 

 Cimex s. str., it would appear that either Acanthia or Lygaeus should be 

 interpreted as the typical subgroup, hence as Cimex s. str., hence also that
