in the intermediate locality of Louisiana. Besides, the report con- 
tains many original observations by the author and a few new illus- 
trations. Some account is also given of the scale insects which are — 
liable to be imported into Louisiana. Original colored plates are 
given, illustrating the Oyster-shell Bark-louse of the Apple, the Pur- 
ple Scale, the San José Scale, the Long Seale, the Yellow Secale, the 
Apricot Seale, and the Florida and California Red Scales, as well as 
the smut fungus, the Florida Ceroplastes, the Orange Mealy-wing, the 
Chaff Scale, and the Orange Chionaspis. 
Bulletin 7 of the Washington Experiment Station.— Mr, Charles V. Piper, 
the newly appointed Entomologist to the Agricultural Experiment Sta- 
tion at Pullman, Wash., in Bulletin 7 publishes his first entomological 
information. He treats of the Pea Weevil and the Cottony Maple- 
scale, the accounts being mainly compiled. The Cottony Maple-scale, 
which he determines as Pulvinaria innumerabilis, is stated to occur 
upon Currant, Gooseberry, Plum, Pear, Hawthorn, Mountain Ash, Lom- 
bardy Poplar, Weeping Willow, Flowering Currant, the Upland Willow, 
and Swamp Willow. It does not occur upon either of the native maple 
trees, which are abundantly planted as shade and ornamental trees 
in that State. This fact in itself should have suggested to Mr. Piper 
that the Northwestern species differs from that of the East, as it really 
does, since numerous specimens received from the State of Washington 
have convinced ts that the species is new, although properly placed in 
the genus Pulvinaria. 
Bulletin 6 of the same station contains a short notice of the Woolly 
Root-louse of the Apple, with an interesting plate showing the roots 
of seedlings affected and unaffected. 
Report of the Entomologist of the Louisiana Station — Bulletin 22, second 
series, of the State Experiment Station at Baton Rouge, La., con- 
tains the reports of the officers for the year 1892. Prof. H. A. Mor- 
gan reviews his work of the season on pages 731-736. He reports that 
the Corn Root-worm (Diabrotica 12-punctata) destroyed many young 
corn plants, and that the greatest damage was done between the first 
of March and the first of May. Soaking the seeds of corn and melons 
in undiluted kerosene emulsion for twenty-four hours is stated to hasten 
germination and to ward off the attacks of the beetles. The adult 
insect is known in that part of Louisiana as the “ Betsy Bug.” Experi- — 
ments with different solutions for use on cattle to keep off the Horn Fly . 
showed that a fish-oil emulsion made by dissolving half a pound of 
common white soap in1 gallon of boiling water, adding 2 gallons — 
of fish oil while still hot and thoroughly churning the mixture for four
