Phaonia texensis new species 



Male and female. — Black, subopaque, densely gray pruinescent. Antennae 

 reddish yellow, third segment brownish apically; palpi reddish yellow. Thorax 

 with four fuscous vittae, and posteriorly with a central brown vitta which 

 extends over disc of scutellum. Abdomen with a slightly interrupted dorso- 

 central fuscous vitta, and a pair of less distinct brown spots on each tergite; 

 apex of fourth tergite rufous ,yellow. Legs reddish yellow; all femora broadly 

 infuscated basally, tarsi black, ^^'ings clear, both cross-veins conspicuously 

 infuscated, the outer with its extremities more conspicuously so than its 

 central part. Calyptrae white. Halteres yellow. 



Male. — Eyes hairy, separated at narrowest part of frons by a distance two 

 or three times as great as width across posterior oceUi; orbits narrow, strongly 

 bristled to anterior ocellus; parafacial at base of antennae at least as wide as 

 third antennal segment; cheek twice as high as widest part of parafacial; 

 setulae continued .'-ome di.stance above vibrissa; third antennal segment about 

 three times as long as second; longest hairs on arista as long as width of third 

 antennal segment; palpi broad. Thorax with three pairs of presutural acro- 

 stichals, and four pairs of postsutural dorsocentrals; prealar long; hj'popleura 

 with a few fine hairs on upper margin in front of spiracle. Basal abdominal 

 sternite bare, fifth with a deep posterior excision. Fore tibia unarmed at 

 middle; mid femur with bristles on basal half of posteroventral surface; mid 

 tibia with about six unequal sized bristles in a double series on posterior side; 

 hind femur with short bristles on anteroventral surface, which are weak basally 

 and become stOut as they near the apex, the posteroventral surface with similar 

 bristles on apical third or more, which is contrary to the general rule in Phaonia, 

 where they are almost alwaj's en the basal half on this surface; hind tibia with 

 one anteroventral and two anterodorsal bristles and a series of stout setulae 

 on anterior and posterior surfaces Outer cross-vein very conspicuously bent 

 inward at middle. 



Female. — Similar to the male but the frons is over one-third of the head- 

 width, and the hind femur has the posteroventral bristles less distinct. 



Type. — Male, and one male paratype, Brownsville, Texas, 

 November, 23, 1910, at sugar, (C. A. Hart). Allotype and one 

 male paratype, same locality, December 17, 1910, (C. A. Hart). 

 Paratype, male, Uvalde, Texas, April 4, 1916, (Bishopp, No. 

 5670). Type in collection of Illinois Natural History Survey. 



Phaonia texensis variety flavofemorata new variety 



Differs from the typical form in having the mid and hind femora or all 

 femora reddish yellow, and the hypopleura bare. 



It is possible that this is a distinct species, but my material is 

 insufficient to enable me to decide.
