Anisota stigma has always been a very common species in 

 the vicinity of Newark and was abundant in 1908. 



Anisota senatoria was quite rare in 1906-07 but in 1908 

 it turned up in great numbers. 



Dryocampa rubicunda : This is a thing of the past in 

 Newark. There used to be several places in Newark on which 

 hundreds could be collected, but these places have been de- 

 stroyed, and there is no chance for this species again getting 

 a foothold. 



All Papilio caterpillars were rare with the exception of tur- 

 nus. This species turned up in great numbers in September. 

 Eggs and caterpillars could be found on almost any tulip or 

 wild cherry trees, but by the end of September a disease at- 

 tacked the caterpillars and it was not long after that it took 

 close searching to find any specimens at all. 



It will be noticed by the above statement that many species 

 were reduced by disease and parasites, and it will be interest- 

 ing to watch conditions and take notes next season. 



The Genitalia of the Group Noctuidae of the Lepi- 



doptera of the British Islands. 



BY JOHN B. SMITH. 



The above is the title of one of the most interesting and 

 important works that has appeared concerning the Noctuidas 

 of any country for some years. It is not a bulky work less 

 than 100 pages but there are also 32 plates with over 300 

 figures, illustrating almost every British Noctuid species. The 

 author of this work is Mr. F. N. Pierce, F.E.S., of Liverpool, 

 and the publisher is A. W. Duncan, 65 South John Street, 

 of the same city. 



The subtitle states that it is "An account of the morphol- 

 ogy of the male clasping organs," and the first plate is devoted 

 to an illustration of an ideal structure in which all the parts 

 are named. This gives us, for the first time, a consistent and 

 well considered terminology for these organs, and the figure 

 is here reproduced on a somewhat smaller scale for the bene- 

 fit of American students.
