Thorax large and inflated, brownish black in color, the anterior 

 half thickly golden pilose with a few black hairs along the median 

 line. Posterior half of the dorsum (more or less abraded in this 

 specimen) black pilose, as are the "postalar callosities. Scutellum col- 

 ored as the thorax, flattened, of nearly uniform width, with black pile 

 except in the center. Upper pleura inflated, yellow pilose above, 

 black below. Squamae smoky hyaline, the surface and border with 

 short black pile. Coxae blackish brown, the front pair yellowish 

 pilose, the others black pilose. Femora blackish brown with black 

 pile, paler at base and tip. Tibiae blackish, yellowish at tip, which is 

 enlarged and with a slender spur above. Tarsi yellow, the claws 

 yellow at base. Tibiae and tarsi with very fine, short yellow pile. 

 No empodia or pulvilli present. 



Abdomen very broad and inflated, but the venter flat, the general 

 shape being very near that of Lasia, in which the fifth segment is 

 much smaller than the fourth. The first three abdominal segments 

 and basal half of fourth with rather short black pile, posterior to this 

 the pile is golden yellow. Ground color of abdomen brownish black, 

 near a dark mahogany color. Venter clothed with reclinate golden 

 yellow pile. Genitalia blackish marked with yellow, with yellowish 

 pile. 



Wings brownish hyaline, a little darker near the base. Veins black- 

 ish. Venation nearly identical with that of Lasia (see PI. XI, fig. 2). 

 As in some species of Lasia the upper branch of the third vein (R4) 

 ends in the first (R1+2-I-3) beyond its junction with the second. 

 The lower branch of the fourth vein is missing. 



This remarkable species would go in the subfamily Pano- 

 pinae. Some of the genera in this group have a rudimentary 

 proboscis, such as Ocnaea and Astomella. It has several char- 

 acters in common with Lasia, the general shape of the body 

 being strikingly near that genus and the venation is almost 

 identical. The Leptidae, Nemestrinidae and Cyrtidae are sep- 

 arated from Other families by having the empodia devel- 

 oped pulvilli form and it is remarkable that this species should 

 have no sign of pulvilli or empodia. The claws close to- 

 gether along the inner edges as in some of the Asilidae, such 

 as Lcptogastcr, some species of which have not even the 

 usual bristle-like empodia. This would seem to be a very 

 important and deep-seated character, but on account of its 

 close resemblance to the genus Lasia it would not seem ad- 

 visable to erect a new subfamily to receive it. Owing to the
