TEUCHOPIIORUS. SYMPYCNUS. 185 



cimen, and will probably require some correction ; the color of the 

 first joint of the antennas is so characteristic for this species, that 

 there is no probability of its being mistaken for another. 



Gen. XXXI. TEUCHOPHOR18. 



The genus Teuchophorus remains hitherto confined to but a 

 few European species. They rather resemble the small species of 

 Chrysotus, but are easily distinguished from them by the follow- 

 ing characters : Antennae smaller ; arista distinctly dorsal. The 

 abdomen of the male somewhat compressed laterally. The pos- 

 terior transverse vein, which is far distant from the margin of the 

 wing, has an extremely steep position, so that its posterior end is 

 farther from the root of the wing than its anterior end. The 

 feet of the male are fringed with isolated, strong, stiff bristles, and 

 its hind tibiae are curved and adorned in various manners. Besides, 

 in all the hitherto known species, the costa of the male is thickened 

 in the same manner as that of the previously described C. costalis. 

 The other characters of the genus coincide with those of Chry- 

 sotus. 



The name of the genus (from tsvzo?, armor, and $/p<o, I bear) 

 has probably reference to the peculiar organs with which the 

 male is provided. 



Gen. XXXII. SYMRYCNUS. 



Characters. Small, but little shining species, of a rather slender 

 shape. The face is not narrower upwards. Antennae rather 

 small, in the female shorter than in the male ; the first joint with- 

 out hairs ; the arista is inserted upon the edge of the third joint 

 in the vicinity of its basis. The metathorax is not unusually pro- 

 truding nor elongated. The abdomen of the male is more or less 

 compressed laterally. The hypopygium is small, more or less im- 

 bedded ; its outer appendages small, sometimes not distinctly visi- 

 ble. The fourth longitudinal vein, towards its end, is perceptibly, 

 although only slightly, approximated to the third and very little 

 convergent towards it ; it ends somewhat before or into the tip of 

 the wing ; the posterior transverse vein before or upon the middle 

 of the wing, distant from its margin ; the sixth longitudinal vein 

 becomes indistinct long before it reaches the margin of the wing.
