 Dasypogon, p., Fabr. 



Mediastinal vein ending at much beyond half the length of the 

 wing. Subcostal connected with the fore fork of the radial near the 

 tip of the wing. Forks of the radial very long ; hind fork curved 

 forward, joining the costal at a little in front of the tip of the wing, 

 very near the cubital, and connected with it by a transverse veinlet, 

 from whence a spurious vein proceeds to the border. First externo- 

 medial slightly curved and parallel to the cubital in its apical part, 

 connected with the cubital before the middle of the discal areolet by 

 a transverse veinlet, from whence proceeds a second spurious vein, 

 while a third proceeds from the veinlet which connects the first and 

 second externo-medial veins and terminates the discal areo^t. 

 Third externo-medial very slightly curved, forming a nearly right 

 angle with the praebrachial, joining the fourth at a long distance 

 from the border. Subanal connected with the anal at some distance 

 from the border. The wing-veins of this genus indicate that its 

 flight is more powerful than that of other Asilites, and accord with 

 its robust structure. In M. heteroptera and in M. singularis the 

 cubital and the first externo-medial veins are united near the bor- 

 der, and in the latter species the third externo-medial forms an ob- 

 tuse angle with the praebrachial, and joins the fourth at a very long 

 distance from the border.
