THE ENTOMOLOGICAL CODE. 1 ." 



Metatype. — A specimen compared by the author of the species 

 with the type and determined by him as conspecific with it. 



Homotype. — A specimen compared by another than the author 

 of a species with the type and determined by him as conspecific 

 with it. 



Holotype. — A single specimen selected by the author of a species 

 as its type, or the only specimen known at the time of description. 



Syntype. — One of two or more specimens upon which a species is 

 based when no holotype has been selected (=cotype). 



Lectotype. — A syntype selected as a holotype. 



Allotype. — A paratype of the opposite sex to the holotype. 



Monotype. — The holotype of a species based on a single specimen. 



Chirotype. — The type of a manuscript name. 



Plesiotype. — A specimen upon which subsequent or additional 

 description or figure is based. 



Apotype. — = Plesiotype. 



Hypotype. — = Plesiotype. 



Neotype. — A plesiotype selected to represent the holotype when 

 the holotype is lost or destroyed. 



Heautotype. — A specimen named by the author of a species, or 

 one used by him for figuring. Practically a metatype. 



Plastotype. — A cast of a type. 



Morphotype. — The type of the dimorphic form of a specie-. 



Autotype. — = Heautotype. 



Homeotype. — = Homotype. 



Ideotype. — A metatype. but a specimen not from the type locality. 



Androtype. — Male type, Gynetype — female type. 



Various combinations of the above have been used and many 

 other names could be given for particular conditions in entomology, 

 as for specimens from the same nest, as the type of social species, the 

 descendants of the type of a species described from living specimens, 

 from the same batch of eggs, from the same host, &C. 



71. In the case of Coccids or other insects where a description is 

 based on specimens in the natural condition, and on ones mounted 

 on slides, the specimens in the natural condition may !"■ considered 

 as type material, and the slide (or one of the slides if there are more 

 than one) as the type slide, but in case of doubt, or a mixture of 

 species, the type slide shall retain the name.
