OF WASHINGTON. 287 



Although the construction of this organ in its principle is the same 

 in all genera, it varies in detail ; it consists of two round excava 

 tions, one behind the other, which are covered by a membrane 

 (tympanum ?), and in the lower one a long hair perforates this mem 

 brane, being inserted in the bottom of the excavation. 



The tarsi of all the legs are, in the Antistomata, provided with 

 two prominent long and slender claws which stand upon a two- 

 jointed petiole. Between and below these claws is the caruncle, 

 a flat, membraneous disc, with fine radiating striae and often with 

 a minute ciliary fringe around its circumference.

ON THE DISCOVERY OF THE GENUS EUNOTUS IN AMERICA. 

 By WM. H. ASHMEAD. 



In my paper entitled "The Insect Collections intheBerlin Mu 

 seum," read before this society last June, amongst other rarities 

 recognized in the unnamed material in the family ChalcididaB, I 

 mentioned the discovery of the exceedingly interesting Eunotus 

 cretaceus, Walker ; gave a brief account of its synonomy, habits, 

 etc., and took exception to the position assigned it by Walker, 

 Forster, and Ratzeburg, believing it to be neither the type of a 

 new family nor a true Pteromalid. 



It gives me pleasure, therefore, to-night, so soon after the read 

 ing of this paper, to announce the discovery of a species of this 

 interesting genus in our fauna, taken by Mr. E. A. Schwarz, near 

 Savannah, Georgia, and to have my views as to its position sus 

 tained by my friend and colleague, Mr. L. O. Howard. 



The specimen is now in the collection at the U. S. Department 

 of Agriculture, where it may be seen at any time by our ento 

 mologists. 



As the species is large and distinct from the European species, 

 I submit the following description :
