WiUk.) was found in corn tioMs at Farniiiifiton on Jinu» 10 and at Dlooniticld 

 on July 39. Brief reference is made to the occurrence of the l)oll\vorni and 

 its injury to corn in Connecticut; also to .several other insects attacking corn 

 in 191!) including: Anaphothripn striatus Osborn and (T//n/w) J'Ic.siotlirip.H 

 pcrplcruN Beach, wireworms, and several noctuid caterpillars. 



The parsnip web worm (DcprcsHnria herncliana Linn.) was collected at 

 Danbury where it was causing some injury. The mosquito work in 1919 is re- 

 ported upon B. H. Walden (pp. 193-198). The report concludes with miscel- 

 laneous note.s on some 20 different insect pests. 



A reference list of the literature accompanies most of the accounts.

 W. C. O'Kane {N. II. State Dcpt. A<jr., Div. Insect Suppr. Circ. 12 [J919], pp. 

 22, pis. 6).— This report foV the biennium ended August 31, 191S, includes ac-

Notes in connection with insect pests, F. Watts (West Indies Imp. Dept. 

 Agr., Brit. Virc/in Islands Agr. Dept. Rpt., 1918-19, pp. 7, 8). — These notes relate 

 to the leaf blister mite (Eriophyes gos.sypii) ; the cotton worm, which appeared 

 in large numbers late in the season; a large longicorn beetle {Batocera 7-uf>ns), 

 which appeared in Tortola in 1914 and has increa.sed rapidly, attacking and 

 killing nearly all the native tig trees (Ficns .spp.) growing on the hillsides; 

 Diaprepes abhreviatus, whicli is a serious pest of citrus but was not so abiui- 

 dant as in some seasons; and the sweet potato worm {Protoparce cingiddta). 

 which was abundant late in the year in several districts. 



Contributions to the knowledge of insect pests, IV, V, F. Silvestri (Bol.

The natural enemies of these scales are dealt with at some length. Those at-

 Phtcnodiscus (cneus (Dalm.), Cerapterocerus mirabilis (Westw.), Pitcfiyncuron

 Aust. Ann. Rpt. 1919, pp. -^5-^7). — This is a brief report of the occurrence of 

 and work with the more important insects of the year.
