NO. 2024. FLIES IN SUBFAMILY BOTANOBIIN^—MALLOCH. 251 



outer cross vein slightly oblique, penultimate section of fourth vein 

 equal to three-fourths the length of last section of fifth. 



Length, 1.5-2 mm. 



Type.— C&t. No. 15963, U.S.N.M. 



Type-locality.— Montserrat, Trinidad, British West Indies, June 

 27 (A. Busck). 



Paratypes. — Same data, six specimens; and two specimens from 

 St. Thomas, West Indies, August 2 (A. Busck), which I am miable 

 to separate from the Trinidad specunens by any reliable specific 

 characters. 



11. HIPPELATES SUBVITTATA, new species. 



Very similar to texana, but differing m having the yellow color of 

 frons and other parts of the head, uacludmg palpi, much obscured, 

 almost black in some specimens. The triangle is more elongate than 

 m texana, cheeks about as high as third antenna! joint; the meso- 

 notum has the disk anteriorly glossy, with two poUinose gray lines 

 intersecting it, as extensions of the prescutellar pollinose patch, thus 

 giving it the appearance of having three glossy black stripes; the 

 surface hairs on mesonotum are much longer and more numerous than 

 in texana, and the pollinosity on margms of mesonotum and scutellum 

 more distinct. In other particulars the two species are very similar. 



Type.— Cat. No. 15964, U.S.N.M. 



Type-locality.— hongYiew, Texas, March 26, 1908 (E. S. Tucker). 



Paratypes. — Two specimens, same data as type; one, Mound, Lou- 

 isiana, May 24, 1907 (F. C. Bishopp); one, Jefferson, Texas, March

12. HIPPELATES TEXANA, new species. 

 Figs. 11, 13. 



Female. — Similar to nigricoxa but the yellow color is rather more 

 extensive on the legs, and slightly paler; the antennae are entirely 

 black; and the mesonotum is entirely covered with more sparse 

 poUen. 



Frons as in nigricoxa; triangle with sides distinctly convex, the 

 anterior angle not acute but rounded; surface hairs on frons sparse 

 but distinct, though short; antennae distinctly above the average 

 size, third joint rounded on lower side at apex, the upper corner 

 slightly acute, pilosity not more distinct than in other species; arista 

 as in foregomg species; cheeks higher than in nigricoxa, at least one- 

 half as high as width of tliird antenna! joint; the anterior margin 

 slightly produced, marginal bristles pale; upper mouth margm black;
