(1) The selection of material to be sent to specialists for study and 

 determination, as here indicated: 



(a) A series of Californian Hemiptera-Heteroptera has been sent to 

 Prof. A. L. Montandon of Bucarest, Roumania. 



(b) The material in the Noctuid genera Xylomiges and Cncullia was 

 sent to Prof. J. B. Smith, New Brunswick, N. .1.. to assist him in his 

 study of these groups. 



(c) A series of Geonietridse, mostly collected in the Death Valley, 

 California, was sent to Dr. A. S. Packard, of Providence, for determina- 

 tion. 



(d) A small series of Diurnals was sent to Mr. W. H. Edwards for 

 determination. 



(e) Several smaller series and all the Odonata, collected by Dr. Ab-

(5) The work of arranging in permanent shape all the collections. 



Iu the Diptera, mentioned in the last annual report as being for the 

 most part arranged, the remaining families have been classified as far 

 as they are studied in our fauna. In the Lepidoptera the North Ameri- 

 can Diurnals, Sphingid, Bombycid, and Geometrid families have been 

 completely rearranged according to the last published classification, 

 and the very large accessions incorporated. Of North Americau Diur- 

 nals 410 species are represented, and of Geometrids about 290 North 

 American and 102 European species. A systematic arrangement has 

 also been made of the tropical Diurnals, and they are represented as 

 follows :
