and shade trees. In Maine, grass land has up to the present sufiered 

 more than cereal crops, and in the former situation the following 

 species have been most in evidence : Cicadula sex-notata, Deltocephalus 

 inimicus, D. configuratus, Acocephakis striatus, Draeculacephala 

 mollipes, D. angulifera and D. noveboracensis. Damage to fruit and 

 garden crops by Typhlocyba comes and Empoasca mali is frequently 

 very serious. The species affecting forest trees are still so widely 

 scattered that at present it is difficult to suggest any methods of 

 control. While there is no immediate destruction of the trees attacked, 

 the rate of wood formation is distinctly retarded. Among park and 

 shade trees, birches especially suffer from attacks of Oncopsis sp. 

 Conifers are injured by members of the family Cercopidae and the 

 punctures made serve as points of entrance for fungus diseases. 

 Willows are infested by species of Idiocerus, Pediopsis, Empoasca and 

 Scaphoideus. Methods of control that may be applied to leaf-hoppers 

 attacking crops are clean culture, mowing, crop rotation, burning of 

 grass lands in early spring or late autumn, spraying the newly hatched 

 larvae, and the use of the hopper-dozer. A detailed description of 

 the species found in Maine is given.

Typhlocyba comes (grape leaf-hopper) passes the winter in the adult 

 stage. The hibernating individuals emerge from the middle of 

 February until the beginning of April, and feed, before the grape 

 leaves appear, on Sophia ochroleuca (pepper grass), lucerne, peas, 

 spinach, etc. In New Mexico, in 1913, pairing was first observed on 

 19th April and the first eggs were deposited on 1st May. Nymphs 

 w^ere noted on 18th May ; the nymphal stage lasted from 13 to 18 days. 

 The summer broods took, on an average, only nine days to hatch. 

 There are two full broods and a small third brood each year, the last 

 appearing in August.

Complaints of decreased yields of honey due to the presence of 

 thrips in lucerne blossoms have been received for several years from 

 out-lying portions of Nevada. Towards the end of the year 1913-14, 

 preparations were made for the study of these insects. Outbreaks 

 of cutworms in lucerne fields have been recorded at intervals. The 

 investigation of certain Hymenopterous parasites of the codling moth 

 were continued, and various methods of rearing and feeding such 

 parasites received consideration.
