ALLORHINA NITIDA Linn. As a Fruit Pest. lu addition to what 

 Prof. Gillette quotes Irani one of his correepoi. dents at Phoenix, 

 Ariz , about this insect as a fruit pest in the NEWS for February, I 

 wish to say that Allorhina niiida has been very abundant in our 

 Western Maryland peach orchards alor.g the Blue Ridge Mountains 

 during the past season They were conspicuous upon the variety 

 salway in September, and not infrequently from fifty to a hundred 

 were seen clustered upon a peach. "We noticed that fruit which 

 had begun to rot upon the tree was especially subject to their at- 

 tacks They were easily disturbed, and would very often take 

 flight when one approached the tree. 1 have not seen them attack- 

 ing the peach in its normal condition; but I have no doubt they 

 would. We have seen from one to five clusters of these beetles up- 

 on a tree at a time, and when one is disturber! the others take flight 

 immediately afterward, causing much confusion and buzzing.

LONG LIFE OF MOSQUITO LARVAE - Vernon L. Kellogg, Stanford 

 University, California. 



The normal life of a mosquito wriggler is. for those mosquito 

 species whose life history has been studied, only one or two weeks. 

 *Dr. Howard found the normal life of the wrigo'ler of C'n/>.,- 

 piaigens,a mosquito common at Washington, to be seven or eight 

 days. " The length of time." he adds, " which elapses for a gener- 

 ation * is almost indefinitely enlarged if the weather 

 be cool. Larvae were watched for twenty days, during 

 which time they did not reach full growth." 



Eggs were laid by a mosquito in my laboratory at -!.:{<) p. in., 

 October t), 1898. The larvae issued from the eggs on the night of 

 October 10th. I kept these wrigglers in a small jar of water, on my 

 writing table. The direct rays of the sun did not strike the jar, but 

 the laboratory is well lighted, and the wrigglers were in a normal 

 condition as regards light. The temperature of the laboratory dur- 

 ing the day time was about G5-75 F. ; at night, never as low ;i> 

 :-tt, F.. usually not below J0-50 F. Occasionally a little water 

 was put into the jar to replace that lost by evaporation. There were 

 14 larvae on October 10th, They increased in size vary slowly and 

 one after another died. On December lf>th there were six larva- 

 alive, and apparently about full-grown. ()u December 2!)t h live 

 larva? were alive: on January ll.lS'.m, 3 were alive: on January 

 17th, 2 were alive, and on January ;5()th there wa. but one alive. 

 This one lived until February 16th, when it died at the "ripe old 

 age" ot four mouths and a week. No larva pupated.
