Notes on Vespa vulgaris and V. Germanica. clxxiii 



apex to the angle formed by the opposite spots ; there are a few dark 

 scales on its margin, but no oval black spot. 



Tristrigella frequents elms, in May and August. I once bred it. 

 Nicellii is very closely allied to Frolichiella, but'is smaller, paler, 

 with much sharper and brighter markings, and the black scales to- 

 wards the apex more collected into an oval spot. 



I have not yet succeeded in detecting the larva, and am not aware 

 that the species occurs with us at all. 



13. L. lautella. The larva is an oak-feeder, and the pupa is in- 

 closed in an extremely fine elongated cocoon. 



14. L. ulminella, {Schreberella). The ordinary cocoon of the pupa 

 is green or bluish green. Tn July, however, I found two transparent 

 white cocoons in elm-leaves, from which I bred only Schreberella. 



In conclusion, I have only to observe that the species here enume- 

 rated by Von Nicelli, are identical with those bearing the same names 

 in Zeller's Monograph in the ' Linnaea/ as I have been assured by 

 Herr Zeller himself.

Art. XXVII. — On the Specific Differences of Vespa vulgaris, Linn., 

 and Vespa Germanica, Panz. By Frederick Smith, Esq., 

 Assistant in the Zoological Department, British Museum. 



In the first volume of the ' Zoologist ' I published a Monograph of 

 the genus Vespa (Zool. 161), and stated it to be one of the objects of 

 my communication to point out the true Vespa vulgaris of Linnaeus ; 

 and that species is the same which I re-describe in my present paper. 

 From a careful examination of the materials which I possessed eight 

 years ago, I was led to regard what I have now discovered to be two 

 species, as constituting only one. Since I published my former pa- 

 per I have lost no opportunity of acquiring additional testimony, and 

 I must confess that every additional tittle of evidence has been against 

 my former conclusions, although, at that time, my premises appeared 

 irrefragable. I have now to show that I was apparently justified in 

 the conclusions I then arrived at ; and a short account of the differ- 

 ences of the two species will, I think, not only prove that assumption, 

 but also satisfactorily show that the varieties, as I at that time consi- 

 dered them to be, of Vespa vulgaris, constitute two species, namely, 

 Vespa vulgaris and Vespa Germanica. The following observations
