there were myriads on the grass, although at 5 o'clock scarcely any were visihle. 

 Among them he had already discovered a number of a species of Haltica new to him. 



Mr. Waring exhibited two specimens of Plusia orichalcea, recently taken by Mr. 

 Harding near Folkstone. 



Mr. Augustus Sheppard exhibited specimens of Tortrix transitana from Fulham, 

 T. cinnamomeana and Dichelia Grotiaua from Weybridge, and two strongly-marked 

 Demas Coryli, reared from larvae. 



Mr. Meade exhibited some cocoons of a Coccus found in May, from which a num- 

 ber of very minute insects, all alike, had escaped, and a sketch of which he exhibited. 



The President said he thought the holes visible in the cocoons were not made by 

 the Cocci, but by a parasite thereon, — Coccophagus; and he believed he perceived 

 some of them among the Cocci. 



Mr. Stainton exhibited the new species of Lithocolletis, recently described in the 

 ' Entomologische Zeitung ' by Herr Nicelli, under the name of L. Coryli ; also the 

 larva; and pupa; in leaves of hazel. 



Mr. Douglas exhibited Gelechia Walkeriella, from Dartford Heath ; Peronea as- 

 persaua, with its pupa-skin, and Sericoris conchana, both reared from larva; which fed 

 on the leaves of Spiraea Filipendula ; and a species of Coleophora, apparently unde- 

 scribed, for which, if such should prove to be the case, he proposed the name of Inula;, 

 the larva having fed on leaves of Inula dysenterica. 



The President read the following extracts from a letter he had received from I. P. 

 Kirtland, Esq., M.D., Cleveland, Ohio, dated July 15, 1851 : — 



" In the ' Arcana Entomologica ' it is stated, on the authority of Mr. Doubleday, 

 that ' Papilio Ajax is found chiefly in the lower country of the Southern States, east 

 of the Alleghanies ; its range is, I believe, from Virginia to Florida.' But this spe- 

 cies has a more extensive range. At my residence on the south shore of Lake Erie, 

 five miles west of Cleveland, it is not uncommon, and I have found it still more abun- 

 dant at Columbus, near the centre of the State of Ohio. With us the larva feeds upon 

 the foliage of the Anona triloba. This insect, in its various stages of metamorphosis 

 is correctly figured in Leconte's Boisduval's ' History of Lepidoptera.' 



" The P. Marcellus is still more common in the same northern localities, and feeds 

 upon the same shrub. It is also well figured in the work to which I have referred. 

 The pupa-case is occasionally of a pea-green colour, and remains unchanged during 

 the winter. In their perfect state these two species are readily recognized by their 

 peculiar modes of flight, as well as difference in size and markings. 



" P. Asterias in the larva state feeds on all species of Umbellifera;, not excepting 

 Cicuta virosa, the most virulent of our vegetable poisons. 



" P. Philenor, in the same state, confines itself to the several species of Aristolo- 

 chia ; A. Serpentaria, in this vicinity, constituting its principal food. It is badly co- 

 loured in Say's ' American Entomology;' in Boisduval it is better, but far short of the 

 original while living. 



" You will perhaps be surprised to learn that P. Cresphontes, Herbst., described 

 and figured as P. Thoas in Leconte's Boisduval, has found its way as far north as my 

 locality. In the August of last year I captured four beautiful specimens on my lawn. 

 The present season two have already been seen here, and I have received one from the 

 Scioto valley near Columbus. At the south it feeds on the orange trees ; what its food 

 is here I have not yet discovered. I do not think it has visited this section of the 

 country till very recently.
