PSYCHE. 



23 



PROCEEDINGS OF THE CLUB. 



Sth December, 1899. The 2iotli meeting 

 was held at 156 Brattle St., Mr. W. L. W. 

 Field in the ch;iir. 



Mr. R. Haywaid remarked at some length 

 on the results of a recent study of the North 

 American species of Tachys, which will form 

 the subject of a paper soon to be published 

 in the Transactions of the American Ento- 

 mological Society. Figures yvere shown 

 illustrating the more important characters. 



Mr. S. H. Scudder read extracts from a 

 letter of Mrs. A. T. Slosson mentioning lier 

 discoyery of Gryllus liictiiosus on or near the 

 summit of Mt. Wasliington, N. H. 



He also showed specimens of the dark 

 form of the mature larya of Papilio folyxenes 

 recently described in Psyche by Miss C. G. 

 Soule, remarking that it was virtually an 

 extension of the coloring of the fourth stage 

 into the fifth, and by the closure of the yel- 

 low spots on the dark ground (normally open 

 in front) recalled strikingly the markings 

 of the European species, P. machaoii^ also 

 exhibited. 



He further called the attention of the Club 

 to the striking differences between the Or- 

 thopteran fauna of Europe and the United 

 States. Of our 205 recognized genera, only 

 26 occurred in Europe, and half of these 

 were cosmopolitan.

Scudder's Brief Guide to the Com- 

 moner Butterflies. 



By Samuel H. Scudder. xi -|- 206 pp. 



i2mo. $1.25. 



An introduction, for the young student, to 

 the names and something of the relationship 

 and live* 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 bv 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 froin the author's 

 puipose to treat them as if they wereso man\' 

 mere postage-stamps to be classified and ar- 

 ranged in a cabinet. He has accordingly 

 added to the descriptions of the ditlferent spe- 

 cies, their most ob\'ious 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 S.\MUEL H. Scudder. 1S6 pp. i6mo. 

 $1.00. 



In this book the author has tried to present 

 in unteclinical 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- 

 opliient, 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. By using a single 

 butterfly as a special text, one may discom-se 

 at pleasure of many : and in tlie limited field 

 which our tiative butterflies cover, this meth- 

 od has a certain advantage from its simplicity 

 and directness.
