the genus before entering on the next grand group. 

 Only three species are classed under the name of 

 Collyris, the two former belong to it at present, the 

 latter is a Ctenostoma of Klug. 



Sp. 1. Longicollis. — The type of the Genus Col- 

 lyris. — Latreille was the first person to change the 

 name of Collyris to Colliuris. M. M. Audouin and 

 Brulle have very properly restored the original 

 name. The Baron De Jean however, in his last 

 Catalogue, still maintains his partiality for Col- 

 liuris. 



Sp. 2. Aptera. — It may here perhaps save the 

 student some loss of time to inform him that Col- 

 lyris aptera, Fab. is totally distinct from Trycon- 

 dyla aptera of Olivier. Colliuris major, Latreille, 

 is the same insect as Collyris aptera, Fab. The 

 following genera compose the family.
