ART. 11 FLIES OF THE GENUS SPATHIMEIGEFLl ALDRICH 9 



SPATHIMEIGENIA BRIDWELLI, new species 



Male. — Front narrowest at extreme vertex, where it is 0.35 of the 

 head width by micrometer measurement — the widest of any of the 

 species. The parafrontals and parafacials are also wider than in 

 the others, the former being but little narrower on each side than the 

 frontal stripe, the latter as wide as three-fourths the length of the 

 third antennal joint; cheek wide, three-sevenths of the eye height. 

 The pollen of the parafrontals, parafacials, cheeks, and posterior 

 orbit is subsilvery, with no yellow tinge. Antennae black, rather 

 short, third joint barely twice the second. Facial ridges with four 

 or five small bristles, extending about one-fourth of the way to base 

 of antennae. The parafacial has the usual group of black hairs, 

 which are rather numerous and almost cover the lower two-thirds. 

 Thoracic chaetotaxy as in genotype, except that there is no inner 

 presutural. Abdomen shining black with very narrow silvery basal 

 bands on segments 2, 3, and 4; on the sides of the last two a very 

 delicate tomentum forms a grayish subopaque patch on each, rounded 

 above and covering all but the anterior and posterior edges (this is 

 a very characteristic feature, similar to the " sexual patch " that 

 occurs in other male tachinids, and should readily identify the 

 species). 



Legs black; claws and pulvilli short. Front tibia with two bristles 

 on outer hind side, middle tibia with two on outer front. 



Wings slightly darkened toward base ; calypters white. 



Length, 7 mm. 



One male, Baldwin, Kans., June, collected by J. C. Bridwell. 



7'y^^.— Male, U.S.N.M. No. 43357. 



SPATHIMEIGENIA TEXENSIS, new species 



Male. — Front rather wide, at vertex measuring in the single speci- 

 men 0.32 of head width, continuing at same width three-fourths of 

 the way to antennae. Pollen subsilvery on parafrontals, parafacials, 

 cheeks, and posterior orbits. Facial ridges bristly two-fifths of the 

 way to base of antennae. Parafacial narrower than third antennal 

 joint, with rather sparse dark hairs from the middle downward. An- 

 tennae black, second joint a little shorter than in the other species, 

 hardly one-half the third, which is rounded at apex. Cheek one- 

 fifth eye height. Thorax with subsilvery pollen, not so grayish as 

 in other species; chaetotaxy as in genotype. Abdomen badly dam- 

 aged, but the last three segments appear to be shining on posterior 

 half, discals if present must have been minute. Legs black; claAvs 

 and pulvilli small. Wings rather evenly pale brownish, apical cross
