central black area. Wing covers brown (testaceous) to flesh color, 

 pretty constantly marked with black as follows : Two spots at the base 

 of each wing cover; two spots at the middle of each, and a couple of 

 contorted ones, narrowly united, near the tip. Beneath, the body is 

 black, the legs largely black, but showing red or brown on the middle 

 of the tibiae. The wings are ample, and the legs, though short, are 

 used with some address, though when disturbed the beetles are dis- 

 posed to draw them up to the body and let themselves drop to the 

 ground. At Warsaw, April 27, 1901, they were found in large num- 

 bers on young nursery trees not yet leafed out, and as one passed 

 among them they made a constant pattering on the dead leaves on 

 the ground. 



The beetles are always abroad during April in Kentucky, be- 

 ginning in the middle of the month. Larvae have been found at 

 Lexington May 26, and pupae on June 1. On June 17, 1901, adults 

 began to emerge from pupae kept in confinement at the Station, from 

 which it appears that the early spring brood is about two weeks ahead 

 of that developing at the latitude of Central Illinois, where according 

 to Professor Forbes pupation began on July 1, and the first adults 

 emerged on July 3. The eggs are placed in clusters attached by their 

 ends to the leaves. They are yellow, smooth and about 0.056 inch 

 long. 



The grubs are variable in color with age, from yellow to black- 

 ish ; have three rather strong pairs of jointed legs, and at the tip of 

 the body are provided with an adhesive organ by means of which 

 they can cling. When ready to become pupae, the tip of the body is 

 secured to the leaf, and after a time the skin is moulted and pushed 

 down in a wrinkled blackish mass next the leaf, leaving the yellow 

 and black pupa projecting. An alcoholic example of the pupa meas- 

 ures 0.2G inch in length. The wing pads extend downward close 

 against the sides. The legs are held close against the breast. 



Both larvae and adults feed on the foliage, and can be destroyed 

 by the use of sprays of Paris green, or of arsenate of lead. One pound 

 of the former in 100 gallons of water is a good proportion, with 

 enough freshly slaked lime added to make the whole milky in color. 

 Of the arsenate of lead three pounds in 100 gallons may be used. 

 The insects are little disturbed by birds owing probably to a powerful 

 secretion, that can be recognized years after collecting, in alcoholic 

 specimens. 



The Willow Flea-Beetle. A small oval, leaping, metallic green, 

 blue, or bronzy, beetle, with pale brown antennae and legs is common 

 in early spring on willows and sometimes poplars and other trees, 

 which it injures by gnawing round holes in the leaves. At times it 

 becomes common enough to do severe injury, but generally its work 

 on foliage is passed by unnoticed because of its insignificant charac- 

 ter. The life-history of the insect is imperfectly known, beyond the 

 fact that the adult lives through the winter. A specimen before me 

 measures just 0.1 inch in length. 



The Herald. A green worm, rather common in late summer 

 and fall among the leaves of willow trees in Kentucky, and while it
