I beg to express my best thanks to W. W. Saunders, Esq., for 

 an opportunity of examining this and other novelties in a splendid 

 collection of insects which he has lately received from Northern 

 India, collected by Lieut. Campbell ; a collection exceedingly inte- 

 resting in a Entomo-geographical point of view, coiidiining the 

 peculiarities of the Himalayan and more tropical Lidian forms, 

 and comprising an unusual number of novelties, not only of 

 species but also of genera, in all the orders of insects, and which, 

 as a whole, may be considered as one of the most characteristic 

 collections which has yet been brought to England from the East 

 Indies.
