and examined at leisure, transferring what was (.>f value to another collec- 

 ting bottle. 



Following up this method, I was enabled to fill two large collecting 

 bi)ttles in less than one hour with selected specimens. 



Each e.xamination of the net's contents showed some rare and fre- 

 quently new form of Hymenoptera or Diptera; and in place of the simi- 

 larity looked for, each succeeding day introduced new forms frequently in 

 abundance where none had been seen on the day previous. The order 

 Hymenoptt-ra was chiefly represented, the flowers of a single plant fre- 

 quently containing 5 or 8 Ammophilas i 5 or 20 bees of the genus Atigo- 

 chlora, Agaposiemon and others, together with representatives of half-a- 

 dozen other families. 



The lateness of the season, several heavy frosts occurring before and 

 after the period, may make a statement of the number of forms repre- 

 sented in the Families of aculeate Hymenoptera of interest. 



The numbers do not indicate distinct species in every case, a few 

 will doubtless prove to be male and female of the same species on further 

 examination.

The smaller forms of Hymenoptera were well represented; many 

 large and handsome Dipters were taken; and the orders Hemiptera and 

 Coleoptera, yielded numerous species. In all, several thousand speci- 

 mens were thus secured. 



The writer has not before found a spot yielding such rich returns 

 at this season, doubtless accounted for in the fact that this was the onlv 

 patch of fresh blooming plants of the species given, or indeed of anv 

 species, in this locality. 



CoUect.ng Nolts: Many handsome Ichneumons and several species 

 of Cynipidae were secured in this and previous years by beating the after- 

 math in grassy ravines with a collecting net.

Entomological Society of Washington. December 2. Prof. Riley read a 

 paper on the luminous liirvae which are now recognized as the larvae and larvi- 

 form females of i-'/ieH^'jc/es and Zn/7(.;yje.s. After reviewing the literature on the 

 subject he stated that he first found one of these larva in 1869 in » cellar at St. 

 Louis, Mo., and the figure he made of this larvae is published in LeBarons' 4th 

 Illinois Report. Subsequently he received quite a number of similar larvae
