70 ENTOMOLOGICAL NEWS. [March, 



member ever seeing it in Michigan, but Cook records T. pennipes 

 there. I have never found a specimen of the genus in New 

 Mexico or Arizona. During a two weeks' trip in Old Mexico I 

 saw none, though I went out quite extensively in the country 

 around Orizaba and Cordova in the month of August. These 

 places are, however, from ^ooo to -900 feet above sea-level. 



Other records show the distribution of the genus as follows: 

 Along the Atlantic coast from Connecticut south, and especially 

 in Virginia, the Carolinas, and Florida; also along the Gulf coast 

 of the Southern States, and in Texas. The specimens from 

 which most of the North American species were originally de- 

 scribed by the early writers came from the Carolinas, and two 

 species from Georgia. Other species were described from the 

 region of the Amazon, eastern Brazil and Argentine Republic, 

 Guiana, Venezuela and the West Indies. T. arcuata, a small 

 species which seems to be distinct from T. pennipes, is described 

 by Bigot from Chili, and probably represents the latter species 

 in that region. 



T. pennipes is known inland from Michigan, Indiana, Illinois, 

 Iowa, and occurs in California, as well as in Old Mexico, Brazil 

 and Argentine Republic, as stated above. I have also specimens 

 from San Domingo and Jamaica. 



The next species to T. pennipes in extent of range inland is T. 

 histrio Wlk. (syn. T. trifasciata Lev.) It is recorded from Con- 

 necticut, Illinois and Kansas. 



These two species are the only ones I know that are found any 

 distance inland in the United States. They do not seem to be 

 found, however, more than a few hundred feet above sea-level. 

 Regarding the apparent scarcity of this genus in Mexico, which 

 is mainly a high plateau region, it may be noted that the Biologia 

 Centrali-Americana collections contain, as indicated in the " Bio- 

 logia Diptera," vol. ii, but two specimens of Trichopoda from 

 all the region of Central America and Mexico. These belong to 

 two species: T. pennipes, a 9 from Presidio, Mex. (less than a 

 thousand feet elevation), and T. pyrrhogaster, a from San 

 Geronimo, Guatemala (probably not over five hundred feet ele- 

 vation). It is quite a significant fact that these were the only 

 specimens obtained by the Biologia collectors in all that region. 



As before stated, the only species, so far as I am aware, that 

 has ever been found on the Pacific coast, or even on the Pacific
