GENERAL OBSERVATIONS ON THE GENUS LITHOCOLLETIS. 



ject, has merely served as a starting- 

 point from which Stainton, Von Ni- 

 celli, Douglas, Heeger, Logan, Re- 

 utti, Frey, Herrich-Schaffer and Koch 

 have proceeded in order to amass 

 fresh information and digest it for the 

 public use. The present volume 

 treats only of a third of tlie genus, 

 and will probably in no long course 

 of time appear but a drop in the 

 ocean of Lithocolletidean literature. 



que de point d'appui a Stainton, Von 

 Nicelli, Douglas, Heeger, Logan, 

 Reutti, Scott, Frey, Herrich-SGhaf- 

 fer et Koch, les aidant a faire de 

 nouvelles recherches, et d'en tirer 

 des consequences d'une utilite gene- 

 rale. Ce volume-ci ne traite que 

 d'un tiers du genre, raais bientot on ne 

 le regardera probablement plus que 

 comme une goutte dans I'ocean de la 

 litterature des Lithocolletis.
