45. Agromyza texana, new species. 



Male and Female: This species is very similar to insularis in gen- 

 eral appearance, but differs as follows: The arista is not so much 

 swollen at base, nor for such a long distance; the cheek is much more 

 distinctly produced in both sexes, and comparitively higher anteriorly; 

 the vibrissa is much more conspicuous in the male, and as long as 

 cheek length, in female the vibrissa is comparatively weak and not 

 nearly so long as in male, consisting of one hair only; the thorax is 

 more densely covered with setulce, which are carried at least to level 

 of transverse line of posterior dorso-centrals; the legs are black in both 

 species and the posterior bristles are absent from mid tibis; the wings 

 have the outer cross vein at wing middle, or very slightly beyond it, 

 and the last section of fifth vein slightly shorter than penultimate 

 section. 



Length L5-2 mm.
