ity of the vines as soon as the crop is off, the object being to destroy 
all eggs and young on the vines and force the adults to other localities 
for food or shelter. The few plants left for seed can then be easily 
looked over and the insects handpicked. Handpick'ng in the early 
spring is also recommended. He has not ascertained the method of 
hibernation of the Melon Louse, but advocates the early search for the 
lirst individuals in June, when they should be handpicked and destroyed. 
Later he urges underspraying with kerosene emulsion. The bulletin 
contains a number of new figures, mainly prepared from photographs, 
which, while indicating general appearance and character of damage, 
are otherwise worthless. Bulletin 95 is a short compiled account of 
the Periodical Cicada. The Annual Eeport gives an account of the 
work done during the year and repeats much of the information given 
in the bulletins. If we have noticed Prof. Smith's station bulletins 
more often than those of other station entomologists, it is because 
he is one of the most prolific writers, and because, on the whole, he is 
doing some of the best and most original work. 
The Four-lined Leaf-bug. *— In this bulletin Mr. M. V. Slingerland gives 
an elaborate account of Pcecilocapsiis lineatus, showing that this leaf- 
bug has been very injurious recently to the foliage of currant and rasp- 
berry bushes in the State of New York. The author gives an elaborate 
account of the past history, destructiveness, and distribution of the 
pest, a lengthy list of its food-plants, an account of the insect's appear- 
ance and indications of its presence, classification, life history, and rem- 
edies, followed by bibliography and synonomy, the whole account cov- 
ering something over 30 pages and illustrated by 13 text figures. The 
most interesting portion of the bulletin is the announcement that the 
species passes nine mouths of the year in the egg state and that the 
eggs are deposited in slits cut lengthwise into the stems of plants, 
extending through the bark- wood and nearly half way through the pith. 
In each of these slits from two to fourteen eggs are deposited. The 
insect is single-brooded in New York State. The remedies recom- 
mended are kerosene emulsion for the nymphs, destruction of the eggs 
by pruning, and the capture of the nymphs and adults by jarring into 
receptacles, where they are destroyed. The bulletin is among the 
most commendable of those which come to us and well illustrates 
the author's care and thoroughness, as well as his ability as an 
observer, though it may be questioned whether so much technical detail 
were not better relegated to publications addressed to specialists than 
included in those addressed ostensibly to farmers.
