After being restricted to a lione}' diet for several daj^s, the 

 wasps became cannibals. 



In a preliminary note by M. J. Ko^enau and C'lias. T. Brnes, 

 in Psyche for Decemlier, 1912, there is a statement concerning 

 the transmission of poliomyelitis thrdugli the agency of <S7o- 

 luoxys calcitraus. 



They have apparently transferred the \'irus of poliomyelitis 

 from monkey to monkey throngh the bite of the stable fly, 

 Stoinoxys calcitraus. This does not appear to be simply a 

 mechanical transference, but rather a biological one, requiring 

 a iieriod of extrinsic incubation in the intermediate host. 



NEUE BEITRAGE ZUR KENNTNIS DER TERMITO- 

 PHILEN UND MYRMECOPHLIEN 



E. Wasmann Zeit. f. Wiss. Zool. CI Bd., 1 Heft. 1912. 



This important pa^jer of Wasmann gives an account of many 

 new species of Coleoptera which are found as guests in ant 

 nests. Of the family Staphylinidae there are eight new species 

 described. The family Pselaphid:e has four described under it. 

 The family Thorictidse has three. The family Tenebrionidje has 

 one new species. There is a very full account given of all of these 

 and others. The author from the light of his stvidies is of the 

 opinion that the guest habit conhl not have arisen throngh 

 "natural selection". He thinks that natural selection is not the 

 chief factor in organic evolution, although it is a factor. He 

 believes that the guest habit has arised through spontaneous 

 variation.
