Thirtieth, report of the state entomologist, 1914, E. P. Felt {Univ. State 

 N. T. Bid. 606 (1016), pp. 336. pis. 19. figs. 101).— In the first part of this report 

 the author refers briefly to the work of the year and the more notable events. 

 The injurious insects, next considered, include the lined red bug (Lygidca 

 mendax), tlie species responsible for most of the nil bug damage to apple 

 orchards in the Hudson Valley ; white grubs and May or June beetles ; forest 

 tent-caterpillar ; brown tail moth, an infestation of which was found on Fishers 

 Island, Gardners Island, and the eastern end of Long Island ; army worm ; 

 European pine shoot moth (Evctria buoUana) which has become established 

 in several localities in New York State; box leaf midge (Monarthropalpits 

 huxi), which has become thoroughly established on Long Island and is seri- 

 ously injuring box hedges ; and grasshoppers, a serious outbreak of which oc- 

 curred on the sandy areas bordering the Adirondacks. 



Under the heading of Notes for the Year (pp. 58-01) the author records ob- 

 servations on some of the more injurious or interesting species coming to notice. 

 The fruit insects mentioned include the tent caterpillar ; lime tree winter moth ; 

 green fruit worm ; pear thrips; pear midge (Contarinia pyrirora) ; i>ear psylla ; 

 Itanded grape bug (Paracalocoris scrupcns), a description of the early stages 

 of which are given; .spotttnl winged Idiocerus (Idiocerus maciilipcnnis) ; and 

 San .Jos6 scale. Several grass and garden insects are considered, namely, grass 

 webworms (Crambus luteolcllus) ; yellow field ant ( Solenopsis dcbUis) ; Say's 

 blister beetle {Pomphopaa snyi), unusually abundant and injurious in sovt-ral 

 localities in the State; juniper plant bug (Chlorochroa vhlcri) ; and Iris borer 

 (Macronoctua onustn). Those mentioned as having injured ornamental and 

 shade trees are the European hornet {Vcspa crabro), which attractetl attention 

 through its gnawing off the bark from the small branches of various trees, 

 especially birch; the elm leaf beetle {CaJcruccUa luicnla) ; the gipsy moth, a 

 colony of which was discovered at Xlt. Kisco ; Norway maple leafhopper (Alcbra 

 albostricUa) and scurfy scale {Lrurnspis jnponica) on Norway maple, hitherto 

 regarded as comparatively free from insect pests; pine leaf .scale (Chionaspi.t 

 pinifolkr) ; spruce bud scale {Pfnjsokcnncs pircw), which has become estab- 

 lished in several widely separated districts of the State; the false maple scale 

 (Phcnacoccus acey'icola) ; and mulberry white fly (Tctralcyrodes mori). The 

 forest tree pests noted include the spruce bud moth {Tortrix fitiniferana), ugly 

 nest cherry worm (Archips cerasivorana), maple and oak twig pruner (Eln- 

 %>Jiidioti viUosutii), and periodical cicada. Several miscellaneous pests are also 

 mentionetl. 



A list prepared by F. T. Ilartraan of the Coccid.-e in the collection of the 

 New York State Museum, consisting of 17.3 species of which 4G were found in 

 New York, is next presented (pp. 92-100). This is followed by lists of publica- 

 tions of the entomologist and additions to the collections. Part 3 of A Study 

 on Gall Midges, or Itonidida; (E. S. R.. 33. p. 2.^3), which deals with the trilies 

 Porricondylaria? and Oligotrophiariie and is illustrated by a number of plates, 

 is appended.
