The foregoing notes are derived from observations made during the 

 Cotton Bollworm Investigations in Texas, 1904, by the Bureau of 

 Entomology, U. S. Department of Agriculture. Unless otherwise 

 specifically stated, the cotton bollworm, Heliothis obsoleta Hiibner, 

 was the host, and the observations were made at Paris, Texas. These 

 notes are given in abstract by Quaintance and Brues in Bull. No. 50, 

 Bureau Ent., U. S. Dep. Agric, pp. 118, 119. 



Class I, Hexapoda. 



Order II, COLEOPTERA. 

 NEW SCARAB^ID^. 



By Chas. Schaeffer, 

 Brooklyn, N. Y. 



The rearrangement of the Museum collection of Scarabaeidse 

 necessitated the identification and study of recent accessions as well as 

 of some species collected by myself near Brownsville, Texas, and in 

 the Huachuca Mts., Arizona, which were still unnamed. 



The collection of the late Ottomar Dietz contains a great number 

 •of unnamed species of Diplotaxis mostly from New Braunfels, Texas. 

 These I have attempted to identify in connection with those collected 

 by myself, but, without the study of the types and with the descrip- 

 tions only, poor results were obtained, as Dr. Leconte's descriptions 

 are too short to identify most of the species with any degree of 

 certainty. From the number of unnamed species, most of which are 

 probably new, I have given names to those only, which possess at 

 least some prominent and strong character, which would have been 

 noticed and mentioned by Leconte in his descriptions, had the species 

 been known to him. \
