new genus of Braconidae, which he had recently discovered, 

 which possessed very long palpi. Such genera seemed to occur 

 in special number in certain regions of the West, and he instanced 

 several which he had seen from Colorado. Mr. Schwarz replied 

 that in Telegeusis the character occurs most probably only in the 



ale, and that these long palpi have a sensitive function. The 



male is unknown, and probably larviform. The modification of 

 < ,e terminal joint of the palpi into a long organ occurs in many 

 f enera, and is difficult to explain. 



Mr. Marlatt, apropos to the remark made by Mr. Ash- 

 mead at the last meeting concerning the absence of oak galls 

 on the American oaks in the Kew Gardens, stated that it 

 would be interesting to know whether galls occur on the 

 European oaks in these same gardens, and that, as a matter 

 of fact, galls are rare in arboretum s or cultivated grounds, in 

 stancing the oak group on the grounds of the Department of 

 Agriculture. Wherever the ground is cared for and the leaves 

 carefully raked up and burned, oak galls will be scarce or ab 

 sent. 



Mr. Ashmead said that he had found oak galls on the Smith 

 sonian Grounds, and Mr. Marlatt replied that the Smithsonian 

 Grounds are not so thoroughly cared for as those of the Depart 

 ment of Agriculture. Mr. Waite remarked that among the oaks 

 in the Department of Agriculture there are very few native 

 trees. 



Mr. Howard presented a paper, of which the following is 

 an abstract : v 



A DIPTEROUS PARASITE OF LACHNOSTERNA. 

 By L. O. HOWARD. 



(Author's abstract.) 



The speaker exhibited two specimens of a Lachnosterna of the 

 fusca group ; one bore upon the thorax two groups of Dipterous 

 eggs, one group consisting of five oval eggs laid side by side to 

 the right of the median line, and the other group consisting of 

 four similar eggs, similarly placed, to the left of the median line. 

 The other specimen bore a cluster of seven such eggs to the left 

 of the median line. Each of these eggs was about i mm. long, 

 and of a light yellow-brown color. He had never seen similar 

 eggs upon a Lachnosterna, nor had his associates, Messrs. 

 Schwarz and Pergande, out of many thousands of specimens ex-
