Another Potato Pest. (New England Homestead, for August 8, 



1885, xix, No. 32, p. 309, c. 3.) 



Macrobasis unicolor (Kirby), one of tlie blister-beetles, — identified as the insect 



injurious to the foliage of potatoes, in Furnace, Mass. Beating the insects 



into a basin of water and kerosene oil, or if very abundant, sprinkling with 



Paris green or London purple in water, is recommended. 



Roestelia aurantiaca. (Country Gentleman, for August 13, 1885, 

 L, p. 661, c. 3-4—10 cm.) 



Determination of the above fungus occurring on quinces received from Charl- 

 ton, Mass. It has usually been found associated with insect attack, as in this 

 instance, where the fruit has been burrowed by probably the apple-worm of the 

 codling moth. 



The False Chinch-Bug. (Country Gentleman, for August 13, 1885, 

 L, p. 661, c. 4 — 26 cm.) 



Insects described (but no examples sent) and reported as injurious to radishes, 

 turnips, horseradish, strawberries and raspberries, in Boulder, Col., are, with- 

 out much doubt, the Nysius angustatus of Uhler. It had not previously been 

 known to injure ripe strawberries, but had, according to observations of Prof. 

 Forbes, been quite injurious to the foliage of strawberries in Illinois. Kerosene 

 oil emulsions or pyrethrum could be used to destroy the bug when upon straw- 

 berries, until the fruit is about half-grown. 



The Bag- Worm — Thyridopterjx epheraerseformis. (Country Gen- 

 tleman, for October 1, 1885, L, p. 801, c. 4 — 20 cm.) 



To an interesting account of the habits of a "worm" destroying arbor-vitae 

 hedges in Franklin Park, N. J., and request for information in regard to it, reply 

 is made of its name as above, and the best method for checking its injuries, viz. : 

 application of Paris green, and hand-picking and destroying the cases of the 

 female moth. A figure illustrating the several stages of the insect is also given. 



The Red Spider — Tetranychus telarius (Linn.). (Country Gentle- 

 man, for October 8, 1885, L, p. 821, c. 3-4—38 cm.) 



Mites infesting various garden plants, at Utica, N. Y., are this species, which, 

 standing at the head of the Acarina, approaches near to the spiders. It spins 

 webs on the under side of the leaves, for shelter, while sucking the juices of 

 the various plants upon which it occurs; those upon which it was noticed at 

 Utica are mentioned. It has this summer been discovered in an injurious attack 

 upon a quince orchard near Geneva, N. Y. Kerosene emulsions, soap solution 

 with sulphur mixed, and quassia infusions may be used for killing it. It was 

 the cause of the yellow discoloring of the leaves of a nasturtium in the garden 

 of the writer. [Printed also in this Report, see page 118.] 



The Thirteen-year Cicada. (The Argus [Albany], for October 11, 

 1885, p. 4—32 cm.) 



A paper, read before the Albany Institute, containing remarks upon the ex- 

 ceptional long life-period of the Cicada sepiendecim ; the number of broods oc- 

 curring in the United States and in the State of New York; notice of a thirteen- 

 year brood, and that its occurrence only in the Southern States may be the re- 

 sult of hastened development through higher temperature ; Professor Riley's 

 experiments in transferring the two forms from one region to another ; and 

 record of the planting of the eggs of a thirteen-year brood at Kenwood, near 

 Albany. [Printed also in this Report, see p. 111.]
