XXXI, '20J ENTOMOLOGICAL NEWS 2O3 



There is a large amount of carelessness in regard to data and 

 much time is wasted owing to slipshod methods, not to speak 

 of the possibility of introducing profanity into the vocabu- 

 lary of your correspondents or among those who eventually 

 must receive and care for the specimens. H. S. 



Prof. V. L. Kellogg to leave Stanford University 



It is announced that Prof. Vernon Kellogg will resign his professorship 

 of entomology in Stanford University, July I, 1920, in order to undertake 

 the permanent secretaryship of the National Research Council, to which 

 latter organization he will thereby insure some degree of administrative 

 continuity. It will be recalled that Prof. Kellogg took an active part in 

 relief work in Europe preceding and during the recent war, to which 

 Minister Brand Whitlock pays an appropriate tribute in his recent book 

 on Belgium. It is to be hoped that this change will not withdraw Prof. 

 Kellogg permanently from entomology. 



Return of the Williamson-University of Michigan Expedition 



from Venezuela. 



The Evening News of Bluffton, Indina, for May 17, 1920, announces 

 the return to that city of Mr. E. B. Williamson, whose expedition to 

 Venezuela has been mentioned in earlier numbers of the NEWS for the 

 present year (pages 108,141). With E. B. and J. Williamson, were assoc- 

 iated H. B. Baker, of the University of Michigan, who collected reptiles, 

 snails, shells, ants and other insects, and Will Ditzler, of Bluffton. Mr. 

 Williamson experienced several attacks of malaria and of fly larvae in the 

 intestines. In addition to the localities already noted in the NEWS, 

 collections were made at Boqueron, Maracaibo, Encontrados, Tachira 

 at the foot of the Andes, La Fria and El Guayabo on the Rio Zulia. The 

 Odonata brought back consist of 158 species and 12,411 specimens.
