282 ENTOMOLOGICAL NEWS. [June, 'l6 



discovered the Ceanothus as local and further the fact that in scattered 

 localities it was more or less coated with this scale. Keeping the facts 

 in mind during my numerous trips throughout the state, I found this 

 scale on the New Jersey Tea at numerous localities in most parts of 

 the state. Later in Iowa, I found the same to be true there and in one 

 little prairie valley near Iowa City, it occurred in greatest profusion, 

 literally encrusting every stem. At this spot it was noted that many 

 of the heavily encrusted stems were weakened and killed, while upon 

 young stems this scale produced a very characteristic deformation, 

 the stem being flattened and distorted. While widely distributed, it is 

 within this part of the country at least local and has usually been 

 found only in areas of a few square feet or at most square rods, while 

 elsewhere in the locality, though the Ceanothus is abundant, it is free 

 from scale. It is parasitized to some extent but we have been unable 

 as yet to mature the parasites. Mr. Sasscer has been kind enough 

 to give me the following data regarding the distribution of this insect, 

 to which I have added those noted by me. To Mr. Sasscer I am fur- 

 ther indebted for most of the citations of literature which follow :
