part of tliis i-op(ir( coiisisls larjicly of accouiils of (lie insppcCion of mirscrics, im- 

 ported iiur.sery stock, imported buli)s, and apiaries. This is followed l)y an 

 a(<'ount of tlie S'P^y Hiid brown-tail moth work in 1919, by \. W. Davis (pp. 

 l.Sr)-144). The white-pine weevil {I'i)i.sodcn strobi Peek), which causes more 

 damaw to younsj white pines in Connecticut than any of its enemies, is next 

 considered, a sunnnary being given of the present status of knowledge of this 

 wtHJvil (pp. 14-1-irir)). A number of parasites of this pest have been reared 

 in Connecticut, including Cocloidrs pissodis Ashm., Ilnhrobraconidca hicoloripcs 

 Viereck, Microhvacon nanus Prov., Eurytonia pissodis Girault, and RhopaHctts 

 tiuspcnsus Ratz. A reduction of the amount of injury caused by it may be 

 accomplished by removing and destroying tlie infested leaders. 



The pine-hark aphid {Chcnncs pinicovticis Fitch), winch has been found 

 throughout Connecticut, is considered at some ibngth (pp. 155-^1 fiO). It was 

 attacked by a luimber of insects, including lady beetles, a syrphid larva, and a 

 crysopid. Experiments to control the chrysanthemum gall midge {Diarlhron- 

 otnyia htjpof/wa Loew) are described by M. P. Zappe (pp. 161-165). The re- 

 sults obtained indicate that the pest is best attacked while it is still in the 

 egg stage, or shortly afterward before the young larvte are entirely within 

 the leaf. Scalecide killed all eggs and young larvse, but injured the foliage. 

 Xicotin sulphate, 40 per cent, and soap, applied every 3 or 4 days, will con- 

 trol it. 



A sunnuary of information is given on the green clover worm (I'hifhypcna 

 scahra Tabr.) on beans (pp. 165-170). An outbreak of this worm occurred dur- 

 ing the year 1919, and bean plants in nearly all parts of the State were sud- 

 denly riddled. The injury is caused by the larvae which eat irregular holes 

 in the leaves. Applications of arsenate-of-lead paste, 1 oz. to 1 gal. of water, 

 caused destruction of all larva? present, and only a few were living on the rows 

 treated with blackleaf 40, -1 teaspoonful to 1 gal. water, with 1 oz. of laundry 

 i-oap. 



The present status of the European corn l>orer in the United States is briefly 

 discussed (pp. 170-17.'>). A native borer attacking corn (Pi/raiista ainsliei 

 Ileinrich), a description and brief account of which by Heinrich has been 

 noted (E. S. K., 42, p. 361) is next considered at some h'Ugth (pp. 173-lSO). In 

 examinations of tlie corn fields for the European corn borer (P. nnhilalis 

 IIid)ner) at Milford, a form later determined to be P. ainsliei was found on 

 -March 12. In investigations made from March 27 to May 10, this species was 

 found in corn stalks in a number of towns, including Wethersfield. Cromwell, 

 Middletown, Kocky Hill, Stratford, Orange, Woodbridge, and Hamden, and in 

 New Haven. In nearly all <»f these towns the .stalks of smartweed ( Poly- 

 gonum) in the corn tields contained the larvfc. /'. ainsliei is said to occur 

 throughout the eastern United States, from Massachu.setts as far south a.s 

 Tennessee and in Missouri, Kansjis, and Illinois. No injury by it to tassels 

 or ears was observed. Its injury to corn, so far observed in Connecticut, has 

 not been of such extent or character as to indicate that control measures are 

 necessary. 



A bri(>f account is next given of the common stalk borer (pp. lSO-183), which 

 is present every year in Connecticut and Infests a larg(> number of plants. A 

 tachinid parasite reared from it has been determined as ^fasi(■cra miinidca Desv. 

 (■nniihits pra'fc<*tcUus Zinck is said to have injured corn in the vicinity of 

 New Haven by boring into the side of the stalk near its base (pp. 183-185). 

 The army worm appeared in considerable numbers in one locality. The 

 smeared dagger moth \ (Apatela) Acronycta ohlinita S. & A.l was found feed- 

 ing on corn at Brooklyn in July. The lined corn borer (Hadcna semicana
