the bark. From these the burrows proceed, extending upward into the 

 pith. The beetle also infests the trunks of trees, probably in its first 

 brood. The remedy for the twifij-blight is found in cutting off the 

 blighted twigs as soon as observed, and burning them. For the attack 

 upon the trunk, no remedy is known. 



18G1. The Entomologist. Xo. XXV.— The Quince Tiiigis. (The 

 Country Gentleman, February 14, 18G1, xvii, p. 25— 45 cm.) 

 Insects sent from Leomin.ster, Mass., with account of serious injuries 

 to quince trees for the past three years, from July until late in the au- 

 tumn. The eggs are laid and the insects work on the underside of the 

 leaves, causing them to color and shrivel as if scorched by fire. The 

 general appearance of the Tingidm of the Ilemiptera, to which the in- 

 sect belongs, is described, looking like little drops of dried froth made 

 up of numerous air-bubbles. This species is similar to Tinrjis pyri, of 

 Europe, and is almost identical with Tingis arcuaia of Say. Dr. Fitch 

 had described a form found on butternut leaves as T.juglandis, but he 

 has since come to the conclusion that it is but a straight wing-margined 

 form of T. arcuata. The quince form is described and figured, and 

 compared with 2\ arcuata, and is named Tingia cydonioi. Its young 

 form is also described. No remedy is known for its injuries. For 

 destruction of noxious insects, the Hydropult, made by the American 

 Hydropult Co. of New York, is highly recommended. By means of 

 this, a number of alkaline washes and bitter infusions may be con- 

 veniently showered, and often with great success. [No notice of this 

 species appears in Dr. Fitch's Annual Reports.] 



18G1. The Entomologist. No. XX VI.— The Wheat-Midge. (The 

 Country Gentleman, April 1, 1861, xvii, p. 226 — 39 cm.) 



For about thirty years, the midge has existed in the State of New 

 York, as a formidable wheat pest. Last summer it was remarkably 

 diminished or wholly extinct. Two species occur together in our wheat 

 fields, the C. iritici and C. cerealis of similar habits, but the last is 

 much the more rare. The habits and transformations are given. The 

 C. tritici may be readily recognized when it enters our windows at- 

 tracted by lights on warm and sultry evenings in June, by the bright 

 yellow color of its body unlike any other minute fly that occurs in the 

 same situation. They usually appear in the wheat-fields in New York, 

 about the 15th of June. A guide for looking for them in other locali- 

 ties would be, at the time when the first solitary fire-flies are seen 

 abroad, and when the white flowers of the locust-trees commence to 

 fade and drop to the ground. 



18G1. The Entomologist. No. XXVII. — Disappearance of the 

 Wheat-Midge. (The Country Gentleman, May 2, 1861, xvii, 

 p. 290—36 cm.) 



In 1859, the wheat in Central New York was reported as not injured 

 by the midge. The following year, the insects were abundant about 

 lamps in Washington county (Eastern New York), during the middle 

 of June, but in July, no larvae could be found in wheat-heads in a cir- 

 cuit of several miles. The same exemption from attack was found
