No new species have been found this year attacking the

more important of these beneficial insects have been investi- 

 gated, with a view to obtaining a more accurate knowledge 

 of the conditions favorable to their multiplication. The

Dixtrilmtton. The species of Calosoma and Haiydlus 

 above mentioned are as a rule quite generally distributed 

 throughout the infested district, although they occur chiefly 

 in sections to which, by reason of their peculiar habits, 

 they are particularly adapted. Of these species, Calosoma 

 scrutator is the least common, no doubt, for the reason that 

 its large size, brilliant color and clumsy movements render 

 it more susceptible to the attacks of its various enemies. 

 Its occurrence is limited chiefly to wood and brush land. I 

 am informed that the C'.iloxomas, especially scrutator and 

 calidum, are very abundant in brushland near the salt 

 water at Belniont, X. J., so much so that it is very common 

 for vi-itors to catch the brilliantly colored scrutator and 

 wear it as an ornament. The occurrence of this species, in 

 eastern Massachusetts at least, is more limited, and it is 

 considered by many local collectors as a very rare beetle. 



Calosoma frigidum i- much more common, and is found 

 in orchards where the gra>- lias not been cut, in wood and
