SCENOPINIDAE. 97 



crassicornis Bellardi, Sa?gio, etc. II, 88; Tab. II, f. 16. — Mexico. 

 argentata Bellardi, Saggio, etc, II, 89. — Mexico. 



Observation. Mr. Walker's Therevae: 



coiispicua Walker, List, etc. I, 223. — Nova Scotia. 

 geriuaua Walker, List, etc. 1, 222. — Florida. 

 nervosa Walker, List, etc. I, 223. — Georgia. (""). 

 senex Walker, List, etc. I, 224. — Nova Scotia. 

 Taria Walker, List, etc. I, 221. — Florida. 

 Ticiua Walker, List, etc. I, 222. — Nova Scotia. 

 Theraa ptayiata (Harris) Walker is Stichopoi/on trifamatus (Say). 

 These species are represented in the Brit. Mus. by a single specimen pach, 

 except T. germana, of which there are two. Most of them will coincide I think 

 with Say's and Loew's species; the others will hardly be recognizable from Mr. 

 Walker's descriptions. 



Xestomyza. 



Wiedemann, JSlova Dipt. Genera, 1820. 

 *l)laniceps Loew, Centur. X, 38. — California. 



Observation. The genera Baryphora Loew, Stett. Ent. Z. 

 1844 p. 123; Tab. II, f. 1— .5, and Clonophora Egger, Verb. Zool. 

 Bot. Vtr. 1854; Tab. I, f. 1, 2 are evidently related to Xeffto- 

 mijza, although Scbiner has, perhaps prematurely, united them with 

 it. The antennae of Banjphora, as figured by Loew, are remar- 

 kably like those of Tahuda, but Iook very different from the 

 figure of the antennae of Cionopliora. 



Tabiida. 



Walker, Dipt. Saund., 197; 1850-56. 



♦fulvipes Walker, Dipt. Saund., 197; Tab. VI, f. 4. — New Jersey 

 (Evett, Proc. Ent. Soc. Phil. I, 217); (Walker gives no locality); 

 Georgia (coll. v. Roeder).
