trally and 2 dorsally, all of which are more stout. 

 The front is short and rather wide with 6 slender, black, 

 bristly hairs laterally. Vertex rather deeply excavated 

 with steeply sloping sides; the ocellarium is set an- 

 teriorly or forward and the whole of it rises above the 

 eye; it is moderately large and high with a pair of 

 stout, long, divergent bristles arising behind the ocelli, 

 together with another pair of considerably shorter, finer 

 bristles adjacent and a similar pair between the ocelli. 

 Anterior eye facets moderately enlarged. 



Thorax: The thorax is pollinose; the pile of the mes- 

 onotum is fine, rather long and bristly but comparative- 

 ly limited in quantity. There is a row of minute, acros- 

 tical pile followed by a wide apilose band and laterally 

 opposite the humerus a patch of numerous, bristly hairs. 

 There are 2 long, slendei-, dorsocentral bristly hairs be- 

 fore the suture, 1 at the suture, and 3 behind. Lateral 

 bristles are long but comparatively slender and consist 

 of 1 posthumeral, 1 notopleural, and 1 supraalar, 2 

 postalar, and 3 pairs of slender scutellar bristles ; these 

 bristles are either black or white or mixed in colora- 

 tion. Scutellum convex, with distinctly impressed rim, 

 densely pubescent with a few fine, slender hairs on the 

 disc. Pleuron with rather abundant, long, fine pile and 

 no bristles. Hmnerus is similar, with abimdant, long, 

 fine pile. Upper middle sternopleuron, the pteropleu- 

 ron, and the posterior half of the mesopleuron with ex- 

 ceptionally long and unusually delicate pile. Posthy- 

 popleuron with a patch of 12 or 15 hairs and the meta- 

 pleuron with a wide band of very long pile among 

 which are some bristly hairs. Lateral slopes of the 

 metanotum creased medially, convex and with numer- 

 ous, long, fine hairs. The posterior basalare bears a 

 few, fine hairs ventrally ; tegula pubescent only ; squama 

 with a multiple fringe. 



Legs: The femora and tibiae are rather elongate, 

 especially the hind pair with the pile abundant, rather 

 fine, setate and appressed and more scanty ventrally. 

 The ventral surfaces of all the femora bear some ex- 

 ceptionally long, slender bristles but oiily 2 or 3 are 

 present on the basal half of the hind femur, 2 basally 

 on the anterior femur and a row of 9 on the middle 

 femur. Of the tibia both the anterior and middle pairs 

 have some quite long, attenuate bristles. On the hind 

 femur 2 long and 1 short bristle, the long elements 

 occupying the basal third; this tibia has 3 fine, quite 

 short, dorsomedial bristles extending to the middle and 

 a like number of dorsolateral elements extending to the 

 outer tliird, with 2 Short, ventrolateral bristles on the 

 outer half. Middle femur with 9 rather long, slender, 

 ventral bristles; its tibia has 3 or 4 quite short, fine, 

 dorsal bristles, 2 exceptionally long anteroventral 

 bristles ; 2 posteroventral bristles and 1 posterior bristle 

 at the outer fourth. Anterior femur with 2 or 3 fine, 

 long, bristly hairs basally; its tibia has 2 very long, 

 posteroventral bristles near the middle and a compara- 

 tively dense, moderately long fringe of fine, somewhat 

 curled pile posteriorly. Anteriorly a brush of setae 



extends to the middle. Posterior basitai-sus nearly or 

 quite as long as the remaining segments combined. 



Wings : The ambient vein complete ; alula only a little 

 wider than the costal cell. 



Abdomen : The abdomen is slender with nearly paral- 

 lel sides and considerably less wide than the meso- 

 notum ; however, the luiusually protuberant, convex, not 

 emarginate firet tergite almost approaches the width of 

 the mesonotum. Pile of the abdomen fine, setate and 

 appressed, with stout, pale bristles laterally along the 

 posterior margin; the first and second segments bear 

 considerable, long, fine pile laterally. First tergite with 

 7 pairs of slender bristles. Eight tergites present in 

 the male, the eighth at least half as long as the seventh. 

 Male terminalia moderately large and constructed 

 somewhat like Astochia Becker, prominent and not 

 rotate. The superior forceps simple, with either acute 

 or obtuse apex, and sometimes swollen and humped 

 dorsally. The proctiger is prominent and directed 

 either vertically upward or even backward. Gonopod 

 of moderate size; hypandrium short. The upper and 

 lower forceps tend toward divergence and the aedeagus 

 is curved upward and expanded below. 



Distribution Neotropical: Senoprosopis hrnsiliensis 

 Schiner (1867) ; ?w.pen<^en^ Wiedemann (1828) ; tenuis 

 Wiedemann (1828) ; varipes Schiner (1867). 



Ethiopian: Senoprosopis coxalis Becker (1923). 



Oriental: Senoprosopis diardii Macquart (1838). 



Australian: Senoprosopis lascus Walker (1849); 

 meridionalis Hwiion (1901). 



Although I have not seen the type of genus, Seno- 

 prosopis diardii, which was said to be from India, I 

 have examined the types of Senoprosopis hrasiliensM, 

 inipendens, tenuis, and varipes, all through the courtesy 

 of officials at the Vienna Museum. Of these species, 

 Senoprosopis hrasiliensis approaches nearest to the fig- 

 ures of Macquart and like Macquart's species it has 2 

 or 3 strong, isolated, long bristles on the ujiper face 

 as well as the nan-owed face. The only points in doubt 

 have to do with the presence or absence of hairs on the 

 metanotal slopes and the presence or absence of an 

 impressed rim on the scutellum in the type of diardii^ 

 since all other Asilinae known to me from the Old 

 World do have these last peculiarities present, I have 

 little doubt that the South American species listed above 

 are true members of Senoprosopis. Stenasilvs Carrera 

 (1960), may be a synonym.
