30 THE entomologist's record. 



structural type. At the moment, I have not the information as to the 

 particular species Stephens designates. Lederer considers this genus 

 as not different from Hadena. Other writers consider it as a section, 

 or as an independent generic type. If the latter view prove correct 

 it must be called Xylena, and the later Xylina, Tr., must fall as a nom. 

 bis. lect., or as used in a wrong sense. — 1816. Ochs., 4, 85 : vetusta 

 and 29 other dissonant species. Cites Hiibner, and includes his type. 



LiTHOPHANE, Hiibn., 1816. — Type: L.socia. — 1816. Hiibn., Verz., 

 242 : petrificata {socio) and four other dissonant species ; a mixed 

 genus. — 1874. Grote, 6th Peah. Rep., 31, takes socia as type, and 

 refers Graptolitha, Hiibn., as synonymous. This name should be hence- 

 forth used instead of Xylina, Tr. The reason is, that Hiibner's type of 

 Xylena is a Hadenoid form mixed by Ochsenheimer with Lithophanoid 

 forms. Later authors take out of Ochsenheimer's genus the latter as 

 the types of Xylina (Ochs. writes Xylena), instead of taking out the 

 Hadenoid forms, which contain the true type of Xylena. 



Lampra, Hiibn., 1816. — Type: L. fimbria. — 1816. Hiibn., Verz., 

 221: fi,mhria; sole species, and therefore type. This name should be 

 used for Speyer's lirst section of Triphaena. In America we have but 

 one yellow-winged Ayrotis (in sensu Led.), (jihipennis, Grt. ; but we 

 have a number of other species which appear to have the same struc- 

 ture w[t\ifi)iihria. I do not find any difference, and, if my opinion is 

 coiTect, Rhi/nchayrotis, Smith, is a synonj'm of Lampra. Georyx, Hiibn., 

 Verzeichiiss, 1816, must, I think, l)e regarded as a synonym of Agrotis, 

 Hiibn., 1806. 



Amathes, Hiibn., 1816. — 1818. Hiibn., Verz., 222: litiira, baia \ a 

 mixed genus ; lihira is an Ortho)<ia. The name Noctua, used by Guenee 

 and other writers is, as I understand the matter, pre-occu2)ied in the 

 Birds and, although it is somewhat of an anachronism to have a family 

 Noctnidae without a genus Noctua, it would seem that we must use 

 Amathes with the tj'pe baia, for the genus usually called Noctna. 

 Lederer and German authorities do not recognise the various genera 

 erected at tlie expense of Agrotis, and the structure of our very 

 numerous North American Agrotidians must be yet compared with the 

 European. The types of Hiibner's genera, in the Verzeichniss, referable 

 to the Agrotidians, must be all ascertained and apjilied so far as they 

 are warranted. Tlie term Amathes has priority by a page over 

 Ochropleura, whicli contains plecta and musiva, species apparently 

 agi'eeing in structure with baia. Later authors have used Ochropleura, 

 and the tyjie of this latter may be held to be plecta, and the generic 

 name, Chersotis, Bdv., would be synonymous. 



guRRENT NOTES. 



As a rule, entomological writers are anxious that their writings 

 should be read, but the excess of zeal in the science of names makes 

 some of us doubtful occasionally, as to what we are reading about. 

 Here is a paragraph about Ealia icanaria, Linn, (wavaria, Fab.) : — 

 '' ILeteropldeps atrosignata, Walker, is, I think, a synonym of Thanonoma 

 wavaria, L. It is nearly the normal form of T. wavaria, as found in 

 America, though this differs somewhat from the ordinary European 

 form, the lines being more distinct and blacker, and the colour a clearer.
