SOME REMARKS ON GNATHOCERA VALIDA, JANS. 

 AND GNATHOCERA COSTATA, ANCEY. 



J. R. H. NEERVOORT van de POLL. 



Mr. 0. E. Janson makes in the "last published part of 

 his „Notices of new or little known Oetoniidae" n". 10 

 (Cist. Ent. Vol. m, p. 146. 1885) the following observa- 

 tion: »Gnatocera valida Jans., Cist. Ent. HI. p. 105 (Feb. 

 1884), is apparently the same as G. costata Ancey, Nat. 

 Sicil. n. p. 95 (1883)." — Possessing a couple of G. va- 

 lida from the same source as Mr. Janson's type specimen , 

 and having received a couple of G. costata from Mr. 

 Ancey himself, I may observe that these species are quite 

 distinct, and it will be useful to point out the differences. 

 In general form the males are very close , but the female 

 of valida is decidedly broader and more robust than the Q 

 of costata. — G. valida has the underside , the legs , the 

 elytral outermargin and the suture pitchy red, all the 

 corresponding parts of G. costata are black. — Finally 

 the mesosternal processes are totally different, the process 

 of valida being long and bent downwards , that of cos- 

 tata long and curved upwards with the apex obtuse.
