ENTOMOLOGICAL GLEANINGS FROM ALL QUARTERS 

 OF THE GLOBE. 



[The Conductors of ENTOMOLOGICAL NKWS solicit, and will thankfully receive items 

 of news, likely to interest its readers, from any source. The author's name will be given 

 in each case for the information of cataloguers and bibliographers.] 



To Contributors. All contributions will be considered and passed upon at our 

 earliest convenience, and as far as may be, will be published according to date of recep- 

 tion. ENTOMOLOGICAL NEWS has reached a circulation, both in numbers and circumfei- 

 ence, as to make it necessary to put " copy 1 ' into the hands of the printer, for each number, 

 three weeks before date of issue. This should be remembered in sending special or im- 

 portant matter for certain issue. Twenty-five "extras" without change in form will be 

 given free when they are wanted, and this should be so stated on the MS. along with the 

 number desired. The receipt of all papers will be acknowledged. ED.

Prof. JOHN B. SMITH'S fine work on Economic Entomology is completed 

 and now on sale; it is a work that every entomologist should have, espe- 

 cially beginners. See Entomological Literature, No. 41, this issue. 



Dr. GARRY DEN. HOUGH, of New Bedford, Mass., is studying the very 

 difficult Dipterous family Muscidae and would be pleased to receive ma- 

 terial for study. He also desires other Diptera by purchase or exchange. 



ASYMMETRY IN BUTTERFLIES. Turning over some old letters yesterday 

 I came across one by Mr. Sydney Webb, of Dover, England, containing 

 some interesting statistics regarding asymmetry in European Lyccenidse. 

 The letter is dated Jan. 14, 1885, and gives an enumeration of the speci- 

 mens of five species in the cabinet of the writer, showing the proportion 

 symmetrical and asymmetrical on the underside, thus: 



Symmetrical Assymmetrical Totals 



Chrysophanns phloeas ... 2 4 6 



Lyccena corydon 20 40 60 



adonis 2 18 20 



agon . . 15 14 29 



" alsus 6 10 16 



45 86 131 



Mr. Webb adds: " These undersides are chiefly asymmetrical through 

 spots being wanting or causing streaks. The specimens with additional 

 ocelli are much more rare." This subject appears by no means to have 

 received the attention it merits, and I will venture to suggest that th< >se 

 who have large series of Lycsenidae, Satyridre, Nymphalidre, etc., might 

 favor us with some further statistics. Particularly, it should be ascertained 

 which species are not frequently asymmetrical, whether these are equally
