some of the egg-parasites of Malacosmnn americana. Fonr separate 

 lots of eggs were collected during the spring and were kept under 

 different conditions, some being placed in a greenhouse, some in the 

 open air and others in cold storage. Six species of parasites were 

 bred from these eggs, the most abundant being the Eulophid, Ahlerus 

 disiocampae, Ashm. This insect was described as a caterpillar parasite, 

 but as the Aphelininae, the sub-family to which it belongs, are other- 

 wise exclusively parasitic on Coccidae, and as it was afterwards reared 

 by Howard and others from Aspidiotus and Chionasjns, it was supposed 

 that Ashmead had been mistaken. In the present case, not only were 

 the trees from which the eggs were taken practically, if not absolutely, 

 free from scales of any kind, but the egg-masses were in all cases 

 removed from the twigs on which they had been deposited and placed 

 by themselves. In these circumstances the correctness of the 

 original record appears to be completely corroborated. The exact 

 relationships of this insect to such widely separated hosts would appear 

 to be a problem of considerable biological interest. 



Other parasites obtained included the Scelionid, Telenomus disio- 

 campae, which was not abundant, and the Encyrtid, Ooencyrtus disio- 

 campae, Ashm., which was next in abundance to A. disiocampae. 

 A species of Tetrastichus was comparatively numerous, but few details 

 of its life-history could be ascertained, owing to its failure to oviposit 

 normally. It passes the winter as a full-grown larva in the host egg 

 and emerges a few days before the adult host. Two specimens of the 

 Encyrtid, Aphycoidev.s io, Git., were also bred from this moth.

 that this Cecidomyid is now known to occur in widely separated parts

A full account is given in this paper of the life-history, food-plants 

 and natural enemies of this well-known pest. The control measures 

 described include fumigation, dipping and spraying. Full particulars 

 are given of the manufacture and "uses of lime-sulphur. Spraying 

 apparatus and power sprayers are described, including the traction, 

 gas, compressed-air, and gasoline varieties, the last-named being 

 considered the most efficient.
