heralded that the Brown-tail Caterpillars had been killed out, 

 due to unusually mild weather in January, which report was 

 absolutely without foundation, shows that exact information 

 upon these matters is needed. We believe that this investi- 

 gation will have a far reaching importance in establishing 

 some fundamental factors in the natural control of insect 

 life. 



Faimal Survey. — New Hampshire is possibly the most 

 interesting state east of the Rockies in regard to the distri- 

 bution of its animal and plant life, for only in New Hamp- 

 shire does the so-called Alpine Zone, which occurs at the 

 summit of Mount Washington and a few neighboring peaks, 

 occur. Two other distinct life areas occur within the state. 

 It is well known that certain species of insects can exist only 

 in the life zones or areas to \\[hich they are adapted and that 

 in their migrations they often will not become established in 

 zones north of their native habitat. It is, therefore, of both 

 practical and scientific interest to determine the distribution 

 of the insects in the state and to determine exactly what spe- 

 cies are here to be found. We have commenced such a rec- 

 ord, which may be termed a Faunal Survey of the insects of 

 New Hampshire, and shall compile records of all the insects 

 in our own collection as well as those in other leading collec- 

 tions of the United States and of published records of insects 

 taken in New Hampshire, giving- the localities in which each 

 species has been recorded, together with the dates and other 

 necessary information. In this work we have been prom- 

 ised the help of several of the leading specialists in various 

 orders of insects and we trust that ultimately this record 

 may be published as a list of the insects of New Hampshire 

 which will be of considerable service to amateur entomolo- 

 gists, the increasing number of school teachers and high 

 school students interested'in entomology, and scientific work- 

 ers throughout the country.
