Coccince. 



(2) Eriococcus (jiiercus, Comst ; 1S81-1898, N. Syn. Rhizococcus 



quercus, Comst. 

 I found this coccid last year at Andover and Lawrence, Mass., on 

 young white oak and Vacciniuni corymbosuni. It is found in Florida 

 and Georgia on Laurel oak (Quercus laurifolia) and Q. aquatica, Gall- 

 berry and Grass. I have reared a Chiloneurus sp. from this coccid. 



(3) Eriococcus azaleie, Comsi.; 1881-1898. N. 



Found at Methuen, Mass., on Crataegus coccinea. It has been 

 taken at New York and Michigan on wild and cultivated Azalea; also at 

 Washington, D. C, in the department greenhouses on Azalea. 



(4) Gossyparia ulmi, Geoff.; 1 764-1 887. I. 



A very common pest. Found at Amherst, Boston, Brookline, Brigh- 

 ton, Concord, Springfield, Methuen, Andover, and Lawrence, Mass., on 

 native white elm, Scotch elm, and Camperdown elm ; also found at 

 Washington, D. C; New Jersey, Maryland, New York, Michigan, 

 Western Nevada, and California, on Ulmus americana, U. racemosa, U. 

 canipestris, U. montana, and U. fulva. It is parasitized by Cocco- 

 phagus gossypariffi. How., and has been reared by Mr. Cooley, at 

 Amherst, Mass., 1898. 



(5) Ripersia iasii, Ckll.; 1896-1894. N. 



Very often found at Lawrence, Methuen, Andover, North Andover, 

 Dracot, and Haverhill, Mass., in nests of Lasius americanus, Gm., and 

 Lasius tlavus. L.; also found feeding on the roots of China asters at 

 Lawrence ; here also attended by Lasius americanus. All of the genus 

 Ripersia found in Massachusetts are subterranean species and attended 

 by ants. No males of the genus have been found by me. It is presumed 

 that they are viviparous. Mr. R. J. Crew in 1S97 found this coccid at 

 Toronto, Canada, in nest of Lasius americanus, Gm. 



(6) Ripersia Kitigii, Ckll.; 1896-1894. N. 



It is abundant in ant-nests at Lawrence, Dracot, Methuen, and 

 Springfield, Mass., found at the latter place by Dr. George Dimmock in 

 1898. Generally found in nests of Lasius flavus, L., and Lasius claviger, 

 Rog. 

 {7) Ripersia Jiaveo/a, CkW.; 1896-1895. N. 



A very common species found at Lawrence, Methuen, Dracot, and 

 Haverhill, Mass., in nests of Lasius claviger, Rog.
