SiMANTON (F. L.). Hyperaspis binotata, a Predatory Enemy of the 

 Terrapin Scale. — Jl. Agric. Research, Washington, D.C., vi, no. 5, 

 1st May 1916, pp. 197-203, 1 fig., 2 plates, 3 tables. 



The Coccinellid, Hyperaspis binotata. Say, is one of the most 

 important enemies of Lecaninm scales, especially of Eulecanium 

 nigrofasciatum, Perg. (terrapin scale). This beetle occurs in most of 

 the territory east of the Mississippi and extends west of that river to 

 the semi-arid region. In the Atlantic States it is most abundant from 

 Connecticut to Maryland, and is common from New Jersey to IlHnois. 

 The food consists of honeydew, Aphids and their eggs, mealy bugs and 

 soft-bodied scales. The larvae apparently feed on scale larvae and 

 young scales. Adults emerge from hibernation about the middle of 

 April and begin mating about 20th of that month. When feeding on 

 the terrapin scale, the hibernating place is usually at the base of scale- 

 infested peach trees. After emergence, the beetles leave the peach 

 tree until the adult scale begins to secrete honeydew, i.e., about the 

 middle of May. They then return and feed on the scale and its honey- 

 dew until about the middle of July, by which time most of the over- 

 wintering beetles are dead, and the new brood have emerged. There 

 is some indication that a second brood may occur. The eggs are 

 deposited in crevices of the bark near the host. In 1913 the first eggs 

 were observed on 3rd May, but these and later eggs were eaten by the 

 beetles. Eggs laid on 26th May were allowed to hatch. Oviposition 

 reached a maximum on 5th June, and continued until 1st September. 

 The incubation period varies from six to eight days, the average for 

 18 eggs deposited between 27th and 30th June being seven days. 

 The larvae, upon hatching, enter the brood chamber of the scale, where 

 they remain during the first two instars and feed on the larval scales. 

 In the third and fourth instars many mature scales are destroyed. 

 The beetle larva then migrates to the leaves where it continues to feed 

 on such larvae as have been able to reach the leaves. The total 

 length of the larval period varies from 17 to 23 days. It is estimated 

 that one Coccinellid larva will destroy 90 mature scales and 3,000 

 larvae. Pupae appear in the field from 7th to 20th July and occasional 

 specimens as late as October ; they are found attached to leaves or 

 concealed in clusters under the bark. The natural enemies include 

 aphis hons, preying on the eggs, and Brachymena [?] sp., attacking the 

 adult. 



The Mexican Cotton Boll Weevil.— (reor^m State Bd. Entom., Atlanta, 

 Bull. no. 44, March 1916, 22 pp., i figs. 7 plates. [Received 

 23rd May 1916.] 



Anthonoinus grandis. Boh. (Mexican cotton-boll weevil), was first 

 recorded in Georgia on 25th August 1915, when a specimen was taken 

 at Thomasville. By 16th November 1915, records were made in about 

 40 counties, in most of which the insect was abundant. The intro- 

 duction into Georgia was due to the high winds which occurred for a 

 few days before its first appearance. The area of new territory 

 covered by the weevil in 1915 was estimated at 86,000 square miles. 

 A considerable advance was also noted in North-west Texas. 



The annual loss from the weevil in other cotton-growing states is 

 discussed [see this Review, Ser. A, ii, p. 649]. A. grandis is able to
