not contradict this view of their relation 

 as would the fact of non-association. 



In summing up the evidence which 

 I have cited it would seem that: (l) 

 Variations in length of wings are cor- 

 related with corresponding variations in 

 length of tegmina or analogous strtic- 

 tures. (3) In one species of a genus 

 these parts may be quite constant in 

 their proportions to other parts of the 

 body, and in another may vai'y greatly. 

 (3) Consequently, a difference in length 

 of wing or interdependent structure un- 

 accompanied by a diflerence in struc- 

 ture of other parts of the body is but 

 more or less doubtful evidence of 

 specific distinctness. 



Large series of specimens from a 

 wide range of countiy are not only desir- 

 able but necessary in order to arrive at 

 a correct understanding of the relation 

 of closely allied forms. Personally, I 

 have found that wide acquaintance in 

 the held with the various forms has 

 been of great service. 



PROCEEDINGS OF THE CLUB. 



13 Oct., 1S93. The iSotli meeting was 

 held at 156 Brattle St., Mr. S. Heiishaw in 

 the chair. Mr. A. P. Morse was chosen Sec- 

 retary pro tem. 



Mr. Lewis E. Hood of Somerville was 

 elected to active membership. 



Mr. S. H. Scudder sliowed some larvae of 

 a Crambid from Plymouth Co., Mass., which 

 injures cranberry vines by girdling the 

 runners and rootlets. He also discussed the 

 identity of some unknown "book-worms" 

 which had caused damage in a librarv, sug- 

 gesting the possibility of termites and Lepis- 

 midae. Mr. Henshaw suggested that some 

 Ptinid or Tomicus might be concerned. 



^^r. .\. P. Morse showed a larva of Lima- 

 codes scapha found (in beech, its color and 

 angular form suggesting the possibility of 

 protective resemblance to a green beech- 

 fruit. He also read a short paper entitled 

 "Notes on the Orthoptera of Penikese and 

 Cuttyhunk Islands." 



Messrs, Scudder and Morse expressed the 

 opinion that Melanoplus puiictulatiis LIhler, 

 Mel. griseui Thomas, and Mel. Iiellno Scudd. 

 would probably prove to be one species.

Scudder's Brief Guide to the Com- 

 moner Butterflies. 



By Samuel H. Scudder. xi + 206 pp. 



i2mo. $1.^5- 



An introduction, for the young student, to 

 the names and something of the relationship 

 and lives of our commoner butterflies. The 

 author has selected for treatment the butter- 

 flies, less than one hundred in number, which 

 would be almost surely met with by an in- 

 dustrious collector in a course of a year's or 

 two year's work in our Northern States east 

 of the Great Plains, and in Canada. While 

 all the apparatus necessary to identify these 

 butterflies, in their earlier as well as perfect 

 stage, is supplied, it is far from the author's 

 purpose to treat them as if they were so many 

 mere postage-stamps to be classified and ar- 

 ranged in a cabinet. He has accordingly 

 added to the descriptions of the different spe- 

 cies, their most obvious stages, some of the 

 curious facts concerning their periodicity and 

 their habits of life.

Scudder's The Life of a Butterfly. 

 A Chapter in Natural History for 

 the General Reader. 



By Samuel H. Scudder. 1S6 pp. i6mo. 

 $1.00. 



In this book the author has tried to present 

 in untechnical language the story of the life 

 of one of our most conspicuous American 

 butterflies. At the same time, by introduc- 

 ing into the account of its anatomy, devel- 

 opment, distribution, enemies, and seasonal 

 changes some comparisons with the more or 

 less dissimilar structure and life of other but- 

 terflies, and particularly of our native forms, 

 he has endeavored to give, in some fashion 

 and in brief space, a general account of the 

 lives of the whole tribe. Bv using a single 

 butterfly as a special text, one may discourse 

 at pleasure of many; and in the liinited field 

 which our native butterflies cover, this meth- 

 od has a certain advantage from its simplicity 

 and directness.
