1 practically all were gone from the leaves. Copulation was not 

 observed, but probably took place during the migratory period. 



Two important parasites were noted, one a braconid, the other a 

 fungous disease (probably Cordyceps clavulata). The fungus first 

 made its appearance in the latter part of July, when a few individual 

 scales on a single tree were noticed with a whitish discoloration about 

 the edges. In a few days the discoloration had spread over the 

 whole bodies of these insects and had also infested many others, both 

 young and old. Within three weeks the disease attacked a majority 

 of the insects on the five infested trees that were under observation. 

 By the 1st of Xovember it had apparently cleared four of the trees 

 of the scale, while the fifth tree showed only occasional healthy 

 specimens, and these were usually isolated on the tip of a twig. The 

 very damp season no doubt accounts to some extent for the activity 

 of the fungus. 



A small brood of periodical cicadas (Tibicen septendecim L.) 

 appeared in Washington County in July. They belonged to Mar- 

 latt's Brood XIV, and are confined to a very limited portion of the 

 country, principally in the neighborhood of Mapleville. While 

 quite numerous in that locality, the brood did very little damage, and 

 its occurrence is important only as a matter of record. 



Some observations were made to determine the life history of the 

 codling moth (Carpocapsa pomonella L.) for the latitude of Mary- 

 land. About 75 per cent of the first brood of larva? Avere found to 

 enter the fruit at the calyx end. It was found by banding trees that 

 the greater number of larva? of the first brood reach maturity and 

 pupate between June 20 and July 10, but that quite a considerable 

 number do not leave the fruit until later, some first-brood larva? being 

 taken as late as August 10. Eggs from the first-brood moths were 

 collected quite plentifully during July on both leaves and fruit. 

 The majority of the second-brood larva? were found to enter the 

 fruit at other than the calyx end. The larva? of this brood begin 

 coming down about August 1, and the number collected from beneath 

 the bands showed a constant increase from that time until August 25, 

 when it began to decrease. A few larva? collected during August 

 pupated, but the great majority spun cocoons and remained as larva?. 

 Undoubtedly the few pupating individuals were belated first-brood 

 larva?. An interesting case of destruction of codling-moth larva? 

 as they were pupating, by a small red ant, which was not identified, 

 was observed. Scarcely a collection of larva? was made from the 

 banded trees without finding several worms that were being devoured 

 by the ants. 



In Xovember a report was received of injury to chestnut telephone 

 poles by a flat-headed borer of some kind. Specimens of the borers 

 and their work were secured and taken to the Bureau of Entomology,
