of scale insect which is known throughout the whole of its geographical 

 range (and many of them are now cosmopolitan) to have asmanyspe 

 of parasites as this, and that these all came from a single locality, nay. 

 from a single hedge, and, in fact, from a single branch, how extraordi- 

 nary it is! Further, they issued, not in different seasons, but all in 

 practically the same week and from the offspring of probably a single 

 mother Lecanium. 

 The list follows : 



1. Coccophagus cognatus How., $ 2 



2. Coccophagus lletcher in. sp., 9 1 



3. Aphycus pulvinarhe How., 9 4 



4. Enc vrtus flavus How., g % 4 



Encyrtus flavus How., 9 2 



5. Chiloneurus albicornis How., 9 6 



6.- Blastothrix longipennis How., $ 42 



Blastothrix longipennis How., 9 66 



The writer's previous knowledge of these species has been about as 

 follows : 



Xo. 1. Hosts. — Lecanium hesperirtuin, Lee. cerasifex, Lee. persicse. 



Localities. — District of Columbia; Bramley, Ontario: LakeshoreandMapleville. Md. 



No. 3. Hosts.— Pulvinaria innumerabilis, Lecanium fletcheri (former sending.) 



Localities. — Davenport, la. ; Ottawa, Canada. 



Xo. 4. Hosts. — Lecanium besperidum, Lee. cerasifex, Lee. sp. 



Localities. — Los Angeles, Cal. ; Champaign, 111. ; Wooster, Ohio. 



Xo. 5. Hosts. — Lecanium sp., on pine; Lee. carya?. Lee. sp., on Qnercna aquatica; 

 Kermes sp., $ on oak. 



Localities — District of Columbia; Davenport, Iowa; Blufl'ton. S, C. ; Kirkwood, 

 Mo.: England (?). 



Xo. 6. Hosts. — Lecanium robiniarum, Lee. spp. undetermined. 



Localities. — District of Columbia ; Agricultural College, Michigan; England. 



I need only add that if collectors wish specimens of Lecanium fletcheri 

 it will be well to apply to Dr. Fletcher at once, as it is reasonable to 

 suppose that his Arbor ritcv hedge will be comparatively free from 

 scales next season.
