82 PROCEEDINGS ENTOMOLOGICAL SOCIETY OF WASHINGTON. 



Mr. Busck exhibited adults and larvae of the remarkable 

 and rare myrmecophilous beetle Paussus kanncgieteri Was- 

 mann, which were liberally presented to the National Mu- 

 seum by Doctor Boving, together with an interesting paper 1 ' 

 on this, the first authentic larva known of that peculiar family. 

 Two previous records have been made of supposed Paussus 



larvae, but Doctor Boving shows that these must have belonged 

 to other groups. 



The article, of which there is a summary in English, is accom- 

 panied by a beautiful plate. 



Mr. Schwarz referred to an article on the insect fauna of 

 the Great Salt Lake, Utah, published in the Canadian Ento- 

 mologist for 1891, pages 235241, in which some space was 

 devoted to the occurrence, in enormous numbers, on the shore 

 of the lake, of the puparia of the salt-fly, Ephydra gracilis. 

 These puparia accumulate on the sandy shores of the lake in 

 a windrow many inches in width and several inches high. 

 A photograph (Plate VI) illustrating a similar accumulation of 

 Ephydra puparia on the shores of Mono Lake, in California, 

 was taken by Mr. W. K. Fisher in September, 1901. The 

 photograph is here reproduced, the black line along the shore 

 showing the masses of the puparia. The particular species of 

 Ephydra occurring at Mono Lake has been described as Ephy- 

 dra hians Say. 



In response to a query Dr. Howard stated that the washing 

 ashore was a perfectly normal habit of the puparia. 



Mr. McAtee spoke of the Indians drying the pupae, which 

 were considered a great delicacy. Birds, especially the ducks 

 and shore birds, are very fond of these pupae and swallows 

 catch great numbers of the adults on the wing.
