Mr. B. P. Mann said that on June 16, 1872, he -feB-iid-^i^J^- 

 specimen of a wasp^ (^Odynerus? &\>.^ which had seized hold 

 of the end of a horizontal twig of Qaercus alba with its jaws, 

 and by that means supported its body in a horizontal position, 

 the head facing inward towards the tree, with the antennce laid 

 together along the upper surface of the twig. This was just at 

 sunset, and the question recorded at the time was : was the in- 

 sect taking this position of rest for the purpose of passing the 

 night so ? Mr, Mann drew attention also to a communication 

 by Mr. F. G. Sanborn, in the Proc. Bost. Soc. Nat. Hist., xii, 

 p. 98, upon an Ammophila gryphus which " was claspino- a 

 small oak twig with its mandibles and feet, the body elevated 

 one-fourth of an inch above the twig, and the head directed 

 toward its extremity." Mr. Sanborn had told him that he 

 thought this might be a case of tetanus ; but the case is shown 

 still more not to be an anomalous one by a statement which 

 Westwood (Mod. Class. Insects, ii, p. 136) quotes from La- 

 treille, that in the night, or during bad weather, Foenus jacula- 

 tor " fix themselves by their jaws to the stalk of different plants, 

 and are then almost in a perpendicular position."

§ 24. Prof. Zeller's Review of Edwards' Butter- 

 flies OF North Amerkja, Vol. I. Dr. H. A. Hagen 

 called attention to a review of the first volume of Edwards' 

 Butterflies of North America, by Prof. Zeller, in Stett. Entom. 

 Zeit. [see Rec, No. 367], and stated the views of Prof. Zeller 

 in the determination of some species. He considers Parnassms 

 Smintheus as doubtless P. Delius var. intermedius ; he disbe- 

 lieves in the generic rights of Neopliasia Menapia ; Pieris Beek- 

 eri is P. cMoridice ; P. castoria is P. napi var. napaeae. 

 Anthocharis (not Ayithocaris) Cooperi is A. Angeliyia Boisd., 

 whose name has priority. Colias Keewaydin is probably C. 

 Clwysotheme, but Prof. Zeller may have judged from specimens 

 of 0. Ariadne, determined by Mr. Edwards, which Dr. Hagen 

 sent as C. Keewaydin. The difference of C. Meadii from C.
