CANKER- WORMS IN CALIFORNIA. 



On page 167, vol. iv, in reviewing a paper by Mr. Alexander Craw^ 

 we mentioned his identification of the Fall Canker-worm {Anisopteryx 

 pometaria)^ from the larva alone, as open to doubt. The present sea- 

 son, however, Mr. Coquillett has reared the adult insects, and from 

 good material which he has sent us we are able to decide that Mr. 

 Craw's surmise was correct and that the species is identical with the 

 eastern A. pometarki. 



THE MEDITERRANEAN FLOUR MOTH IN CALIFORNIA. 



S¥e mentioned in the November number of Insect Life the appear- 

 ance of EpliesUa Mihniella in fiour mills on the Pacific Coast. The 

 American Miller oi January 1, 1893, has a long article under the title 

 ^' Flour Moths in California," in which it reviews the articles i^ublished 

 by this journal, by Mr. James Fletcher, the Entomologist of the Cen- 

 tral Experiment Farms, Ottawa, Canada, and by Miss E. A. Ormerod, 

 of England, and states that the San Francisco Call has been investi- 

 gating the occurrences of the insect in California. The result of this 

 investigation shows that the Ephestia has already become an alarming 

 pest, and that its work has resulted in the loss of thousands of dollars 

 to a number of large establishments. The Pacific Coast occurrences 

 have been carefully studied by Mr. W. G. Johnson, instructor in en- 

 tomology at Leland Stanford, Jr., University, who is reported as stat- 

 ing that the disastrous effects of the insect's work will undoubtedly be 

 very apparent in nearly all of the mills of the State before the end of 

 another year. 



We may mention in passing that M. J. Danysz has recently started 

 a private "Laboratoire de Parasitologic" in Paris, and has studied 

 the occurrences of this insect in France, and that after thoroughly 

 considering all of the facts he is inclined to agree with our original 

 supposition that the insect is not American in its origin, as has been 

 claimed by European writers heretofore. M. Danyzs, by the way, 

 places less reliance on the use of kerosene emulsion or bisulphide of 

 carbon as a remedy against this insect than upon a strong tobacco 

 wash. 



tent caterpillars in MASSACHUSETTS. 



The Massachusetts horticulturists, taking advantage of the liberal 

 disposition of the State Legislature with regard to appropriations for 

 fighting the Gypsy Moth, propose to memorialize this body for further 

 appropriations to be used against the Tent Caterpillar which has be- 

 come a great pest in certain of the New England States. At a meeting 

 held in December a committee of the State Horticultural Society was.
