British Species of the Genus Gelechia of Zeller. 179 



in the groove of the wing, is a thin black streak having white 

 intervals. Beyond the middle is an acutely-angled buft" fascia, 

 from the costal end of which round the posterior margin to the 

 anal angle are seven or eight long black dots, placed on a buff 

 ground : cilia grey-brown. Posterior wings silver-grey, cilia con- 

 colorous. Body griseous. 



This moth sometimes varies in having on the anterior wings 

 more small black streaks than those I have mentioned. I bred 

 two on the 28th June, 1848, from larva found in leaves of sallows, 

 and took two on 11th July in the evening flying about sallows at 

 Dulwich wood. It is also in the Bentley cabinet, taken, Mr. 

 Westwood says, in the north of England.

Genus Physodeka, Eschscholtz. 



Physodera Eschscholtzii. 



(Plate XVIII. fig. 2.) 



Phys. niger, nitidus, caeruleo-tinctus ; thorace cyaneo ; elytris 



splendide cupreis, marginibus viridi-caeruleis. 

 Long. corp. 3|- lin. ; lat. 1| lin. 

 Inhabits Ceylon and the Philippine Islands. 



Although the present insect wants the bladder-like swelling on 

 either side of the thorax, which characterizes the species on which 

 Eschscholtz founds his genus Physodera, it nevertheless agrees so 

 closely with that insect in all other particulars, that I do not 

 hesitate to place it in the same genus. One is naturally led to 

 question whether the swellings on the thorax may not be a sexual 

 distinction, but on this point 1 have not been able to satisfy myself. 

 Both species, viz. the P. Dcjeanii and the P. Eschschollzii, were 

 brought by Mr. Cuming from the Philippine Islands,* and are 

 now deposited in the collection of the British Museum ; and, upon 



• Wy own specimen of the P. Eschsclmltsii is from Ceylon.
