Algeria tipuUformis (imago figured), Angerona crocataria, Qrapta progney 
and Amphidasys cognataria feed on currants at Quebec : G. J. Bowles, Oanad.

Sexual selection : Darwin Descent of Man,’ &c. yol. i. ch. xi. pp. 386- 
423) devotes a chapter to this subject as regards Lepidoptera. On the pro- 
portion of sexes, see Darwin, 1. c, pp. 309-313, and R. Meldola, Nature, iii. 
pp. 608 & 609. 
Mimicry, see Riley, iii. Rep. Ins. Miss. pp. 169-176 j also Scudder, Butler, 
and Wallace, in Nature, iii. pp. 147, 166. On European species which 
mimic other insects, see Dietze, S. E. Z. xxxii. pp. 279-284. 
Parthenogenesis : see G. A. Kornhuber, Schr. Yer. nat. Wien, v. pp. 368- 
371. Dohrn criticizes Weijenburgh’s remarks on this subject. S. E. Z.

II. Landois, under the heading “ Beitrage zur Entwicklungsgeschichte 
der Schmetterlingsflugel in der Raupe und Puppe ” (Z. wiss. Zool. xxi. 
pp. 305-316, pi. 23), traces the gradual development of the wings of a 
Lepidopterous insect through all its changes from the newly hatched 
larva to the perfect insect, in a series of careful observations and ex- 
peiments. 
Mahey’s observations on the action of the wings of butterflies during 
flight (c/. Zool. Rec. v. p. 177)^ are translated by Pettigrew, Tr. R. Soc. 
Edinb. xxvi. pp. 869-362. 
R.L. Maddox publishes “ Remarks on the General and Particular Construc- 
tion of the Scales of some of the Lepidoptera, as bearing on the Structure of 
the ‘Test-Scale’ oi Lepidocyrtus mrvicolh's” (M. Micr. J. v. pp. 247-266, 
pis. 86-88 ; discussion, pp. 278, 279) — an elaborate paper on a subject now 
exciting much interest among microscopists, with useful hints for further 
investigation. From it, the scales of Lepidoptera would appear to be more 
nearly analogous to the feathers of birds than has hitherto been supposed. 
• S. J. McIntire remarks on the microscopic appearance of the scales of 
certain Lepidoptera. Those of Urania leilus, Pieris agathinuy and P. epicharis 
are figured : ihid. pp. 4-8, pis. 70 & 71.
