14 A Neiu Trypetid. [zOE 



three on each side are nearly straight and directed forward, while 

 the hinder two are curved and directed backward. A pair of 

 curved, divergent, anteriorly directed ocellar bristles. Face and 

 palpi pale silvery, the palpi sparsely clothed with small bristles 

 on lower portion; cheeks, occiput, and proboscis dilute tawny, 

 occiput above bordered with a row of whitish bristles. Thorax 

 slightly silvery cinereous, with three golden brown vittae, clothed 

 with whitish bristles and hairs; humeri and pleurae concolorous; 

 scutellum nearly concolorous, rather triangular in shape, with 

 four bristles, the anterior pair longest, the apical pair hardly 

 decussate. Abdomen brownish, flattened, curved under, some- 

 what ovate in outline, rather pointed behind, quite sparsely 

 clothed with short bristly hairs, and with longer bristles on hind 

 margins of segments. Legs pale brownish fulvous, claws short 

 and blackish. Wings broad, rather long, from apical three- 

 fourth tapering almost equally on anterior and posterior borders 

 to a blunt apex. Picture of wings almost the same as that of 

 E. Mexica7ia, figured by Loew in Monographs, iii, pi. x, fig. 28. 

 Differs from the figure only as follows: Second vein ends 

 about in middle of margin of hyaline spot third from tip 

 on anterior border; of the three marginal hyaline spots of 

 second posterior cell, the two end ones are somewhat elongated 

 inward like the middle one; the proximal one of the two costal 

 hyaline markings in marginal cell does not extend inward below 

 the second longitudinal vein, or is represented by only the 

 merest dot, and the distal one does not quite reach second vein; 

 one (the right) wing shows two hyaline drops about middle of 

 discal cell, the distal one smaller, while in the other wing the 

 smaller distal drop is represented by two very small dots in a 

 line transverse to the wing; five hyaline drops in third posterior 

 cell, two bordering on posterior margin of wing, two approxi- 

 mated to fifth-vein, and one bordering on the sixth (anal) vein 

 considerably removed from the margin; four obscure hyaline 

 drops in the less infuscated anal angle of the wing, inside the 

 anal or sixth vein; the coloring becomes more or less dissolved 

 toward the wing base, the second basal cell being mostly clouded 

 on distal half. Third vein bristly to a point about opposite or a 

 little beyond termination of second vein, first vein bristly nearly
