152 PARIS VIEWED LEPIDOPTEROLOGICALLY. 



M. Guerin-Meneville, who does not so much make a 

 Collection as study the habits and economies of the insects 

 he meets with, and from whom we have obtained several 

 valuable suggestions, showed us last spring a small Lepidop- 

 terous insect, which was totally new to us. We borrowed it 

 for description, and when at Zurich showed it to Professor 

 Frey, who was no less struck with its singular appearance 

 than we were. 



In order to redeem our promise of describing it, we here 

 give a notice of this insect, which is figured on the Frontis-

Stathmopoda? Guerinii, n. sp. 

 Alts anticis dilute olivaceis, facia obliqua albida ante 

 medium, plaga albida pone medium, a venis oli- 

 vaceis intersect a. 



Exp. al. 5§ lines. 



Head whitish grey ; face and palpi white ; antennae grey, 

 slightly pubescent, with long basal joint. 



Anterior wings pale olive grey, a little darker posteriorly; 

 before the middle is an oblique whitish fascia, nearest the 

 base of the wing on the inner margin, the whitish colour of 

 this fascia runs along the edge of the costa and inner margin 

 to the middle of the wing ; beyond the middle is a whitish 

 blotch not reaching to the costa, and intersected by two dark 

 olive-grey veins ; the apex of the wing is whitish, streaked 

 with grey ; cilia grey. 



Posterior wings pale grey, with greyish cilia. 



This singular insect, which was bred by M. Guerin-Mene- 

 ville (after whom I have named it) from a large gall of the 

 pistachio tree, September 15th, 1852, does not appear refer- 

 able to any of our existing genera ; the antennae are only 

 slightly pubescent, whereas in Stathmopoda pedella the
