1903] JOHNSON: — ASILIDAE 1 1 3 



Saropogon bicolor, sp. nov. 



$ . Head black, mjstax and pubescence of the face yellow, antennae reddish, becoming 

 dark brown towards the tip; proboscis black, slightly brownish at the base. Thorax black, 

 with a large quadrate humeral spot from which extends a lateral line of the same color to the 

 base of the scutellum, minute pustules, bearing short hairs give the entire body a punctated 

 appearance ; pleurae and scutellum black, lateial angles of the scutellum and metanotum 

 brownish, pleurae shining. First and seventh segments of the abdomen black, the others 

 red, with a lateral margin of black, the second segment has a narrow continuous posterior 

 margin of black, on the others it extends but a slight distance from the lateral margin; 

 venter black. Halters and legs reddish, coxae, tips of the posterior femora and base of the 

 tibiae, with a very narrow ring of black, the last joint of the front and middle tarsi also 

 black, spines on the tibiae few in numbers and mostly white, those on the tarsi numerous 

 and black. Wings with a light brownish tinge, the veins on the basal half bright yellow ; 

 the fourth posterior cell closed and slightly petiolate. Length 12 mm. 



One specimen said to have been taken near San Antonio, Texas, was given to 

 me by the late Andrew Bolter. 



Saropogon abbreviatus, sp. nov. 



$ . Similar in form to the preceding but the entire body, legs and antennae are a deep 

 black, with the same punctated appearance; mjstax for the most part black. Halteres 

 yellow. Wings brown, the veins black, fourth posterior cell narrowly open. Length 12 

 mm. 



Obtained with the preceding specimen and may prove to be only a variety, 

 but with so limited material I am not justified in uniting them. The difference in 

 the fourth posterior cell cannot be relied on even as a specific character, as it varies 

 even in the same species. Among the four specimens of ^. adustus in my collec- 

 tion, two have it closed and slightly petiolate, while in the other two it is narrowly 

 open. The same variation exists in S. combustiis ; nor is it sexual. 



Near San Antonio, Texas. 



Atomosia sayii, sp. nov. 



This name is applied to the variety referred to by Say under '''' Laphria gla- 

 brafa''^ as " Var. a. Feet pale" (Journ. Acad. Nat. Sci. Phila., Ill, 54, 1823.) 



It is very evident that Say had two species before him, and that the name and 

 description can only apply to the one with — "feet reddish brown, the middle of the
