Bulletin No. 19 of the Massachusetts Station.*_In this bulletin the lead- 
ing article, upon the Gypsy Moth, is by Prof, Fernald, he having been 
appointed entomological adviser to the Gypsy Moth committee of the 
State Board of Agriculture. The article is a full descriptive account of 
the insect in its different states, with a summary of its present distri- 
bution and its food-plants, also an interesting paragraph on the para- 
Sites of the species, in which are mentioned as feeding upon the eggs 
Trombidium bulbipes Pack., Nothrus sp. near ovivorus Pack., and a spe- 
cies of Phieothrips. As issuing from the pupa Theronia melanocephala 
Br. and Pimpla pedalis Cr.—both Ichneumonids—are mentioned, also 
an undescribed Chalcidid of the genus Meraporus. In addition to 
these, several undetermined species of Diptera were reared, and a Sol- 
dier Bug (Podisus spinosus Dall.), black ants and spiders were found 
destroying the larve, while ten different species of birds were also 
observed to feed upon them. In Bulletin 26 of this Divisio n, Mr. Hen- 
Shaw has recorded, upon page 81, a few additional facts upon the nat- 
ural enemies of Ocneria; no other true parasites, however, being men- 
tioned. The article is illustrated with the five excellent plates and the 
map which were used in the Report of the State Board of Agriculture. 
The bulletin also contains a summarized account of “ Barnard’s insect 
trap,” experiments with Paris green on apple trees, especially against 
the Tent Caterpillar, and closes with an account of cranberry insects, 
studied from the Massachusetts standpoint, the accounts of the insects 
so far treated agreeing in general with those by Prof. John B. Smith, 
whose bulletin on cranberry insects we reviewed in Vol. 11, upon page 
Oo. 
Contagious Diseases of the Chinch Bug.t—Prof. F. H. Snow, in his first 
annual report as Director of the Experiment Station, University of 
Kansas, gives a complete summary of his work upon the contagious dis- 
eases of the Chinch Bug, preliminary accounts of which have appeared 
in INSECT LIFE (Vol. III, pp. 279-284, and Vol.Iv, pp.69-71). The report 
includes about 140 pages in brevier type, devoted to the reports of 
farmers and others who have experimented with Prof. Snow’s diseased 
bugs, and the reports as a whole are favorable to the conclusion that 
the disease can be successfully disseminated. To these reports is added 
a consideration of the meteorological conditions governing the inerease 
of the Chinch Bug, and a history of the literature on microphytous dis- 
eases of the Chinch Bug in the United States. We can see no reason 
for changing the opinions which we have already advanced upon the 
practical aspect of this subject and in spite of the great length of its 
present treatment the all-important point of the possible coincident 
origin of the disease without artificial infection is by no means settled.
