45. A specific name, if a Latin adjective, should agree in gender 

 with the generic name, even when published in connection with a 

 subgeneric name of different gender.

 gender with the generic name. 



Example. — Cossus ore Str. is not to be changed to C088U8 orca, 

 orcus, or orcidis. 



47. A specific name given to any part or stage (except egg) of an 

 insect, or to the cast or imprint of a fossil insect, is valid if otherwise 

 available. 



48. A specific name based wholly on a cocoon, case, gall, leaf- 

 mine, or other work of an insect is valid, if otherwise available, only 

 until the insect itself is described, when that name and authority 

 replaces the one based on the work. 



49. A specific name of an insect based wholly on characters of 

 internal anatomy, on habits, or on anything other than external

 rank except as provided in section 37 and certain of the following 

 ones. 



51. A subspecific, or varietal, name is a trinomial.

 of the specific name and have the same type. The name of the 

 typical variety is usually omitted.

 glomus L.).

 a species (fasciatus) which he considers as being the Oryllus fasciatua 

 of DeGeer. It is now known thai the insed before Fitch was no! 

 DeGeer's species. Thus the name (Ecanthua faxchatua cannol hold 

 for the species treated by Fitch, as it was a misidentification, Dot the 

 proposal of a new species.
