1. Eclimus (?) auripilus, sp. n., c? $ . (Tab. HI. fig. 5.) 



Black, opaque, with short, scattered golden pile, and a denser pubescence of longer hairs of darker hue ; wings 



greyish, the veins margined with brown, the brown on the cross-veins assuming the appearance of spots. 

 Length 10-12 millim. 



Sab. Mexico, Ciudad in Durango 8100 feet (Forrer). 



Black, opaque ; the whole upperside of the body clothed with scattered, short, golden- 

 yellow pile, and with longer, erect hairs of darker hue (blackish or greyish, according 

 to the light) ; the underside of the body (of the head, and of the thorax, including the 

 pleurae and the venter) greyish-white, with whitish hairs ; the end of the abdomen of 

 the female with a tuft of rufous hairs. Third antennal joint a little shorter than the 

 first; first and second joints beset with black hair. Hal teres brownish-yellow, with a 

 brown knob. Coxse and femora black, the tibia? brownish-yellow ; tarsi brown, paler 

 at the base. Wings greyish, more brownish at the base and along the costa; with 

 brown clouds on the origin of the second vein, on the anterior cross-vein, and at the 

 base of the four posterior cells ; the veins more or less margined with brown, especially 

 the fork of the third vein. Three males and three females. 



N.B. — I place this species provisionally in the genus Eclimus, Loew. My hesitation 

 is owing to the presence of an exceedingly minute bristle at the end of the antennae in 

 these Mexican specimens, while Loew describes the antennae of Eclimus as " an der 

 Spitze ohne bemerkbaren Griffel." The other differences which I am able to notice 

 between my specimens and Loew's data are slight: the third antennal joint is broader; 

 the anterior branch of the fork of the third vein is more S-shaped, that is, less ventricose 

 at first, but more curved towards the end. I would not establish a new genus on such 

 an uncertain foundation, the more so, as the relations of Eclimus, Thevenemyia, Bigot, 

 and Epibates, O. S., are yet to be determined ; possibly upon the discovery of new 

 forms belonging to the same group it will be found more convenient to unite all these 

 genera. From Epibates, as characterized by me in the 'Western Diptera/ Eclimus 

 auripilus differs in the thorax of the male not being muricate, and the wings net
