SUBFAMILY I. TRYXALIN.E. 199 



Although Scudder in his Catalogue gives the range of T. ~brevi- 

 cornis as "southern U. S.," it has been taken by Walker (1902a, 

 251) as far north as Point Pelee, Out., while Beutenmiiller (1894, 

 291) has recorded it from Long Island, N. Y., and Smith from 

 New Jersey, where it is found in both fresh and salt marsh areas, 

 but more abundant in the latter. From the points mentioned its 

 known range in this country extends west to eastern Nebraska 

 and south and southwest to northern Florida, Mobile, Ala., Frank- 

 lin, La., and central Arkansas, the Nebraska and Arkansas rec- 

 ords being the only ones from west of the Mississippi. East of 

 that stream, from Illinois and Maryland to Florida, it appears 

 to occur frequently in suitable localities, judging from the records 

 of Morse (1904, 28) and E. & H. (1916, 155). In Florida, how- 

 ever, it seems to be quite scarce and no specimens have been taken 

 by me though a male is at hand taken July 22 on the University 

 grounds at Gainesville. The only localities recorded by others 

 from the State are Atlantic Beach, Marianna, Monticello and 

 Everglade. The single female taken at the- last named place by 

 Davis is said by E. & H. (1914d, 104) to measure 39.4 mm. in 

 length of body and to be the largest individual seen from any 

 locality between New Jersey and Buenos Aires, Argentina, to 

 which point the species ranges. 



III. PSEUDOPOMALA Morse, 1896, 325. 



Slender-bodied species having the head conical ; vertex semi- 

 elliptical, horizontal, female, slightly ascending, male, extending 

 in front of eyes a distance equal to its basal width ; disk with 

 sides flattened, concave each side the distinct median carina, apex 

 feebly obtusely rounded; frontal costa rather low and wide, nar- 

 rowed above the antenna?, divergent below, widely and shallowly 

 sulcate; antenna? strongly ensiform (Fig. 84, a], equalling, fe- 

 male, or one-half longer, male, than length of head and thorax; 

 pronotum about one-fourth longer than head, tricarinate, the car- 

 inre parallel, all cut by the principal sulcus distinctly behind the 

 middle; lateral lobes vertical, their front margin straight, oblique, 

 hind ones feebly concave; hind femora slender, subequal to or 

 slightly shorter than abdomen in both sexes; ovipositor short, 

 scarcely exserted, the lower valves furnished with a strong tooth 

 each side. 



This genus, as founded by Morse, was placed in the subfamily 

 Tn/.ralina\ In this he was followed by McNeill (1897, 208). 

 Scudder did not coincide with this placement, and (1899e) placed
