My article contains some accidental remarks only, but I am intended 

 to undertake afterwards more special and detailed examination of the 

 subject. I am Avell convinced that the study of the primary sexual cha- 

 racters is one of the most valuable guides in the recognition of spe- 

 cies; these structures are absolutely invariable within specific limits 

 and they proved invaluable in settling question of the identity of clo- 

 sely allied forms. 



A complete unacquaintance with specific characters in the genus 

 has allowed S t a u d i n g e r to confound C. lara В r e m. with C. cero- 

 gama Gué п., ü. oberthäri А u s t. and C. deducta E v e r s m. with G. elo- 

 cata E s p., C. adultéra M é n. with С. ympta Linn, and unijuga Walk., 

 G. dileda H ü b n. and G. dula В r e m. with G. sponsa L i n п., under the 

 vague term „forma darwiniana". Examining the markings and, espe- 

 cially, the genitalia i see no reason for calling the former of the named 

 above species varieties, or „formae darwinianae"; they must be regarded 

 quite different forms and valid species, belonging in some cases (e. g. 

 dilecta and sponsa) to the different groups of the genus. I have already 

 published some ideas of how the species of this genus should be ar- 

 ranged (this journal, I, 1901, pp. 225 — 230) and i recognize several groups 

 in this genus, based upon morphological characters, the color of hind 

 wings being indifferent. 



As to the synonymy, i propose following „nomina nova" for spe- 

 cies, whose names must be rejected and substituted as fully coincident 

 with others in the same genus. 



Gafocala nupta L i n n. var. centrasiatica Kusnezov 1903, nom. 

 nov., for var. nuptialis S t a u d. 1901, as coincident with G. nuptialis W a 1- 

 k e r 1857 (nearctic). 



Gatocala mesopotamica Kusnezov 1903, nom. nov., for G. aspasia 

 S t a u d. 1896, as coincident with G. aspasia Strecker 1874 (nearctic). 



Gatocala edwardsi К u s n e z о w 1903, nom. nov., for G. mariana H y. 

 E d w. 1875 (nearctic), as coincident with G. eutijchea Treitsch. var. 

 mariana R a m b. 1858. 



Gatocala disjimcta H ü b n. - G e y e r var. fumigata Kusnezov 

 1903, nom. nov., for var. luctuosa Staud. 1901, as coincident with G. luc- 

 tuosa Hülst 1884 (nearctic). 



In regard to the specific names G. scortum Christ. 1893 and 

 С abamita В r e m. and Grey 1853 (not mentioned in the Catalogue), 

 he dates of the description give В r e m e r ' s name the priority.
