iy George Greene, of Philadelphia, has spent several days in the library 
c the Museum verifying references for his catalogue of Coleoptera. 
4 R, A. St. George has recently completed an arrangement of the larvae 
sabia to the families Alleculidae and Tenebrionidae. Mr. St. George 
as done this work under the general direction of Doctor Boving, and reports 
that the National Collection now contains representatives of 6 genera and 
9 species belonging to the family Alleculidae, and 65 genera and 104 species 
‘belonging to the family Tenebrionidae. Much of the material belonging to these 
two families has not been reared, and in many instances specific identifications 
have not been verified. J. S, Wade, of the Office of Cereal and Forage Insect 
Investigations, has deposited considerable valuable material, most of which 
belongs to the genera Eleodes and Embaphion. The nucleus for the collection 
in these two families. was made years ago by H. G, Hubbard and E, A. Schwarz, 
but since then notable additions have been made by H. S, Barber, and others 
have been secured from various offices of the Bureau. It is hoped that various 
field men will collect and rear material belonging to these families.
