THE ENTOMOLOGIST. 177 



to ibis species. The description is, however, valueless, and 

 though Marsham's types belong to Q. rufipes, Grav., I do 

 not see why Erichson's name should not be retained. 



Philonlhus concinnus, Grav. — Tliis is a small form of 

 ebeninus, noticed by Erichson and Kraatz, but apparently 

 possessing constant characters. Thomson has first regarded 

 it as a species, under the name of varians. 



Xantholinus linearis, OLiv. — Thomson makes three species 

 out of this : it is easy to see that his multipunctatus is com- 

 mon here, and in fact corresponds with our longiventris : 

 whether we have a third I am not prepared to say ; but these 

 two, apart from general facies, &c., are readily separated by 

 the finely alutaceous surface in multipunctatus. 



Leptacinus pusillus, jS/e/?//. — L. linearis, Grav.^ clashes 

 with the Xantholinus, and must therefore take the next oldest 

 name. 



Lilhocharis ferruginea, Er. — Here there is probably some 

 confusion. Two or three of my specimens of brunnea 

 answer to the description of the above, in that they have 

 very certainly a longitudinal groove down the thorax, but in 

 all other respects they resemble brunnea. Has Kraatz over- 

 looked this channel in that species ? 



Lithocharis ruficollis, Kraatz. — The name tricolor is quite 

 inadmissible, clashing with the Xantholinus. 



Micracalymma marina, »S'/ro/;i. — Mr. Haliday appears to 

 have first noticed that Strom described the Micracalymma at 

 the same time as the ^£pys, and under the same specific 

 name. It is only just to restore this.

Life-huiory of Orgyia pudihunda. — The eggs are laid in 

 June, in a crowded patch, on the upper side of the leaves of 

 a great number of trees, among which I may mention garden 

 plums of several varieties, Qucrcus Robur (oak), Fraxinus 

 excelsior (ash), Castanea vesca (Spanish or edible chesnut), 

 and Carpiiius betulus (hornbeam), also HumuUis lupulus (the 

 cultivated hop) : they are of a pale lead-colour inclining to 

 white, and opaque at first, but after being laid about fourteen
