species over that of the (.■odliiiK uioth. This increase is »)fteii sufficient to l>ring 

 the total number of the lesser ai)ple worms, in the fruit for tiie season, in 

 excess of the codling moth larviP. 



Overwintering larvie of the lesser apple worm have been found in the cracks 

 and crevices of the barks of trees and also in fruit and barrels which had been 

 stored over winter. They have also been found in great abundance in late fall 

 in the partly devoured fruit of Cratfegus, both on the trees and on the ground. 

 Many larvjie passed the winter in the Cratiiegus fruit in breeding jars, and this 

 overwintering habit very probably obtains under natural conditions. The moths 

 from overwintei-ing larv;e emerge about the same tim<> as those of the codling 

 moth. In the Ozark region the first brood of larvj^e matures usually during the 

 month of June, moths from the second brood of larva^ emei-ging in 1908 from 

 .Tune 20, to July 30. From the evidence at hand it appears that there are 3 full 

 generations annually in the Ozark region. 



Individual records kept from 120 eggs during July, August, and September 

 gave the minimum time of incubation as 4J days, and the maximum 5* days. 

 The length of the larval period from the time of hatching to leaving the fruit 

 varied from 13 to 15 days in July and from 20 to 27 days in August and the 

 first half of September, and increased to from 30 to ~>0 days after the middle 

 of September to early November. From about 100 specimens allowed to spin 

 cocoons in ends of apples, either at the stem or blossom end, the average time 

 during July and August was 7 to 8 days from leaving the fruit to pupation, the 

 minimum being 1 day and the maximum 12 days. The actual duration of the 

 pupal stage varies from a minimum of probably 4 to a maximum of 17 days, 

 averaging about 10 days. A technical description is given of the eggs, which, 

 in rearing cages, were deposited on the upper surface of the fruit stems, etc. 



A specimen of a parasite reared from a larva infesting the apple has been 

 determined as I'lnnicntionia n. sp. It is stated that the usual treatment prac- 

 ticed against the codling moth has so far served to keep in check the serious 

 injury by the lesser ajiple worm. 



New species of Ting'itidae and description of a new Leptoglossus, O. Heidk- 

 MANN (BtiL Buffalo Soc. ^^at. ScL, !) (.WOO), Xo. 2, pi). 231-238. figs. 6).— Four 

 species belonging to the genus Atheas, Corythuca floridana from Fhn-ida, and 

 Leptoglossus ashmcadi also from Florida, are described as new. 



A generic revision of American moths of the family (Ecophoridae, with 

 descriptions of new species, A. Busck (Pnx: U. N. Xat. Mux.. 3.'> (UK)!)), jip. 

 187-207). — The larvtc of the fficoiihoridic are said to have various life modes, 

 though a m.ijority either live in spun leaves or feed in decayed wood. One 

 American genus is parasitic upon Kermes. A few of the sjiecies are of some 

 economic importance as enemies of cultivated crops. Many of the species over- 

 winter as adults in thatch or under bark, or as in the case of some Depressaria, 

 in houses, thereby occasionally causing nnnecessary alarm when they appear in 

 numbers at the approach of warm weather.

 species representing 8 genera are described as new.

The genitalia of the group Noctuidae of the Lepidoptera of the British 

 Islands, F. N. Pikbce (Liverpool. 1909, pp. XII+SS, pis. .12).— This account of 

 the morphology of the male clasping organs is said to record the results of 20 

 years' investigation made in odd hoins. It is illustrated by many i)en drawings.
