Length, loi mm. Differs from de- 

 scription of G. setosa Coq. (Rev. Tach. 

 p. 136) as follows: Tibiae yellowish red, 

 the anterior ones blackish at base. 

 Face and sides of front pale yellowish, 

 former silvery and latter cinereous polli- 

 nose. Second antennal joint yellowish 

 or reddish. Sides of abdomen on first, 

 second, and third segments broadly pale 



red, leaving a broader median area of 

 black between, which widens posteriorly. 

 Front at bases of antennae twice as wide 

 as either eye, at vertex one and one-fifth 

 times width of either eye. The fine 

 bristly hairs on sides of face are in two 

 parallel approximated rows near margin 

 of eyes, there being none between the 

 lateral facial row and the facial ridge 

 row. Cheeks as broad as one- half eye- 

 height, clothed with bristly hairs. An- 

 tennae four-fifths as long as face, third 

 joint nearly or quite three times as long 

 as second. First aristal joint as long as 

 wide ; second four or five times as long 

 as first, and fully one-third total length 

 of last joint, which is much tapered on 

 its final third. The middle tibiae each 

 bear four macrochaetae on front side, 

 the fourth or upper one the shortest, in- 

 creasing in length to the lowest one 

 which is longest. Otherwise agrees in 

 all respects with the characters given for 

 G. setosa.
