and Brazil. It is possible that the wasp under discussion was in- 

 Ti-oduccd here from Mexico amongst freight received from Salina 

 Cruz by the American-Hawaiian line of steamers. 



For examination I have captured 16 males flying over gar- 

 den plants and shrubs, and 18 males and 10 females have been 

 bred from the nests of Sceliphron caementarium as previously 

 noted. A much larger series could, if necessary, be captured as 

 I still notice nuiny of these wasps flying around. 



Note — Since writing the above 1 have received a small lot 

 of endemic Odynerns from Kauai collected for me by Mr. G. P. 

 Wilder, and among these I noticed two males and one female of 

 this newly introduced wasp. This indicates that it is already 

 established elsewhere than on Oahu, and also that the species 

 must have been here for some time past. It is somewhat strange 

 that a series has not been captured long ere this. I now think it 

 possible that the single individual wasp which Mr. F. W. Terry 

 captured a few months ago in the window of a room on Punch- 

 l)Owl and which he exhibited at a meeting of the Entomological 

 Society a few months ago may be the same species. As he is 

 away at this time this fact cannot be ascertained and his speci- 

 men is therefore not available for comparison. 



Mr. Severin related some observations he had made a few 

 weeks previously on the occurrence of J^ematodes in sugar beet 

 fields in California. 



Mr. Ehrhorn, who had recently returned from a vacation 

 trip to California, spoke of the unusual dryness of the regions 

 surrounding San Francisco and Central California, and the con- 

 sequent scarcity of insects, making it exceedingly unfavorable 

 for doing any collecting. 



NOVEMBER 2xi). 1911 



The seventy-eighth regular meeting of the Society was held 

 in the usual place. 



]\Ir. Swezey exhibited a collection of about 50 species of 

 moths collected by Mr. Giffard at his new bungalow near the 

 Volcano House, Kilauea, Hawaii. The moths were collected as 

 they came to lights at night, during the summer of 1911, when 

 Mr. Giffard was making a short stav there at several different
