SCIENTIFIC NOTES AND OBSERVATIONS. 



Generic types in Plusia. — The object of the present notice is to 

 give the types of what seem distinct genera among the British species 

 passing under the title Plusia. Reference should be made to a short 

 summary given in the Proc. Am. Philosopldcal Sucieti/, Dec, 1895, 417. 

 Plusia, Hiibn., 1806. — Type: P. chri/sitis {chnjsitis,Ij.; cJiri/si>n, Esp. ; 

 bractea, Fab.). Polychrisia, Hiibn., 1816. — Type : P. moneta 

 [iiioneta, Fab.). Chrysaspidia, Hiibn., 1816. — Type : C. festucae 

 Ifestucac, L.). AuTOGRAPHA, Hiibn., 1816. — Type : A. ;jamma 

 [j/aiiima, L. ; iota, L. ; pulrJirina, Haw. = v-aureum, Gn. ; interro- 

 (jationis, L. ; ni, Hiibn.). Of the other generic terms the type of 

 A;/ rapha is glauca. Cram. ; the N. Am. acrea is a Plusia. The yellow- 

 winged species, deveiyens and diverf/ens, belong to Si/ngrapha, Hiibn., 

 1816 — with the type devenjens, Hb. — A. Radcliffe Grote, M.A.,

TePHROSIA BISTORTATA, var. gen. II., CONSONARIA. A CORRECTION. 



This varietal name, referred to in my paper on " The Tephrosia 

 Tangle " [ante, p. 81), should be cited to Steph., Wood, ncc Haw. 

 The error, though trivial, annoys me greatly, as I rather pride myself 

 on my care in this kind of work. Through an unfortunate combina- 

 tion of circumstances, I was unable to get access to Haworth's 

 Vol. II., at the moment, and I therefore trusted to Wood — who so 

 often figures the very same specimens from which Haworth describes — 

 for my determinations. These references to Haworth were the only 

 ones which I did not personally verify, and the error shows the 

 importance of obtaining ccenj one at first hand. Haworth's consonaria 

 was described after a single specimen captured in May, and is no 

 doubt the true consonaria of Hiibner (tetragonaria, Steph., Wood). 

 His crejmscularia (p. 177), which would have priority if indubitably 

 referring to the second brood of T. histortata, is too uncertain to be 

 substituted for the clearly defined consonaria of Wood. It {crepuscu- 

 laria, Haw.) certainly includes this second brood, for the month 

 indicated is July ; but in all probability (from the description, and 

 the citation of Hb., 158, as well as from Stephens' and Wood's inter- 

 pretation) it also includes, or is even chiefly based upon, the single- 

 brooded species. The argumentum e silentio, founded on the 

 omission of any mention of May and June, as times of appearance, 

 would be ridiculous. Many of Haworth's descriptions are made from 

 cabinet specimens, and it is most improbable that he always obtained 

 precise data ; consequently ho might have described from any number 

 of cabinet specimens of the single-brooded species, and yet, having 

 captured but one specimen of T. histortata second brood in July, have 

 indicated that as the month for his species ; that is, if we assume
