O«o«r«l. — Mr. Frost mentioned Bayhead. Kew Jersey, as a good

 Jersey, and exhibited the collection he had made at that place while 

 oa a two wedcs* vacatkm at the aid of July.

 with the white markiags nearly obsolete. 



DiptenL- Mr. R. C WilUams said he had been told that the ordi- 

 nary vacwm cleaner nozzle will frighten house flies, but if the nozzle 

 is made of glass the apparatus becomes rery effective as a method of 

 catdrfng flies. He »aid practically the same method has been used to

-aenoptera^ Mr. Laurent stated that last March he had secured 

 tlic trunk of a Norway maple oootaining Bombers of the larvae of 

 Tremfx colmimba. The first specimens ca a crge d on June 16, two males. 

 From the i6(h to the ;od of June, seventy males emerged, but only 

 three females. To the a6th of June, ninety-six males emerged and 

 ten females. Prom the 37th of June until the 7th of July only nine 

 males em erg ed, bat aa females. Prom the Mi of July until the joth 

 of August the inseets co nt i nu ed to emerge, but only 25 specimens made 

 their appearance during these fifty- four days. In all. one hundred

 the males it was sooiewhat different; when they left the hand they

 could not be induced to copulate and none copulatc<l in the main 

 cage containing the log. He had also reared from the log eleven 

 males and five females of the parasite. Mtgorhyssa lunator. as well 

 as a male and female of U. grtenti Vieredc The sixteen specimens 

 of lufMtor em er g e d between May 8th and 12th. He said lunator was 

 not an internal parasite on Tremex cotumba but an external one, and 

 commented on the proportion of parasites to host. 18 to 162.
