There are so many important genera o/ Nymphalids of which I 

 know nothing, that I do not feel justified in ^'oing into more detail, nor 

 in inventing names for the divisions that must unquestionahly be made

:i^ClENTIFIC NOTES & OBSERVATIONS. 



Apteroi s Females and Winter Emergence. — With regard to Mr. 

 Studd's interesting note {ante, p. 87), I believe that he is right in most, 

 if not all, of his conclusions, and it is quite probable that it will turn 

 out after all that there is no direct connection between cold and apterous 

 c(jnditions ; as these investigations are somewhat out of my regular line, 

 I will take to heart our Editor's words (p. 90) " it really is high time 

 that off-hand opinions based on want of knowledge, should be excluded 

 from our so-called scientific magazines,'" and will give in with a good 

 grace. There is only just one little slip in Mr. Studd's note to which I 

 would briefly call attention ; on p. 88 he says, '• it is ditticnlt to resist 

 the conclusion that at all events the llyheruidae and the Chehimtohias are 

 descended from some common jiarent form," etc.. and gives as his chief 

 argument the unquestionably close relationship t)f H. aurantinria and 

 H. marginaria. Now there is no doubt that the genus Hyhemia is 

 at least a fairly natural one ; but it is open to serious question 

 whether either Avisopteryx or Chehnatohia really comes very near it. In 

 Herrich-Scha^ffer's system, where the Geometridae are divided into two 

 great classes, Dendrometridd' and Phytumetridae, according to neuration, 

 Ilybernia belongs to the former, the other two to the latter ; in fact, 

 Cheiviatohia seems to be A'ery close to Oporabia, which is but an autiimnal 

 division of the Lareutiidae, associated by Lederer with his ra,s/«/a-group 

 of the genus Cidaria. At any rate, it is a curious coincidence that so 

 many winter species which cannot possibly spring from a recent common 

 ancestor should in common poss^ess apterous females, and the matter is 

 worthy of investigation. — Louis B. Prou'i-, 12, Greenwood Koad, 

 Dalston, N.E. Feh. 22nd, 1895. 



Parthenogenesis in Ocneria dispar. — While the subject of parthe- 

 nogenesis m Lepidoptera is to the fore, through Mr. Tutt's carefully 

 collected notices (Ent. Record, v., p. 289 ; vi., p. 4), J venture to send 

 one supplementary reference which has come under ni}^ notice. In the 

 Archives NeerJandaises, v., 1S7U, pp. 258-264, H. Weijenbergh, jr., contri- 

 butes " Quelques Observations de i)arthenogenese chez les Lei)idopteres," 

 in which, besides citing the records of this }ihenomenon" which he had 

 met with, he recounts in detail some experiments of his own with Ocneria
