rohwer: generic name ceropales 173 



tional discussion of this point is, however, not necessary for this 

 particular case because the species referred to Ceropales in 1802 

 cannot be the genotype in accordance with opinion 46. Briefly 

 reviewed the case is as follows. 



In 1796 Latreille described the genus Ceropales but assigned 

 no species to it. The description he gave, while rather general 

 and applying in most points equally well to certain genera in 

 the families Psammocharidae and Sphegidae, has two charac- 

 ters (viz. the semi-circular labrum and long hind legs) which as 

 far as the groups concerned are involved, apply only to the genus 

 belonging to the Psammocharidae. In 1802 (Hist. Nat. Cms. 

 Ins., 3: p. 339) Latreille again characterizes the genus Cero- 

 pales and this time cites the species quinquencinctus Fabricius 

 and doubtfully "campestris f F." It would appear thus far 

 that quinquencinctus would have to be the type of Ceropales, 

 but this species does not agree with the original description in 

 the following characters: "Levre superieure demi-circulaire" 

 and "Pattes posterieures longues dans quelques especes." Since 

 quinquencinctus does not agree with the description it cannot be 

 the genotype (opinion 46 says, "the genus contains all of the 

 species of the world which come under the generic description 

 as originally published") and in fact Latreille corrected his error 

 in 1804 (Nouv. Diet. Nat. Hist., p. 180) and 1805 (Hist. Nat. 

 Crus. Ins., 13: p. 283) and placing quinquencinctus in a new 

 genus, Gorytes, and citing maculata Fabricius as an example of 

 Ceropales. Added proof that Latreille desired in 1804 to correct 

 the error of 1802 is found in the fact that in 1804 Ceropales 

 and Gorytes are the only genera to which species are assigned. 

 The species maculata agrees with the original generic description 

 of Ceropales and could correctly be named as the type of the 

 genus. This is exactly what Latreille did in 1810 (Cons. Gen. 

 Crust. Ins., p. 437). 



It is almost certain and partly confirmed by Latreille' s re- 

 marks in 1802 (Hist. Nat. Crust. Ins., 3: p. 335) that as 

 characterized and understood in 1796 the genus Ceropales con- 

 tained species now placed in Ceropales and also species now re- 

 ferred to the genus Gorytes {s. I.) but inasmuch as the characte
