Pale testaceous ; vertex, centre of metathorax (but not the sides, 

 scapulas, or scutellurn), and the extremity of abdomen black above ; 

 antennas compressed, finely ciliated, yellowish at the base and blackish 

 •beyond the middle. Legs testaceous, except the tips of the hind 

 tibiae and the last three or four joints of the hind tarsi, which are 

 black. Wings hyaline, brown at the base and extremity. Fore wings 

 narrowly vitreous at the extreme base, and with two vitreous spots in 

 the median and submedian cells ; the stigma and adjoining portion of 

 the costa, above the vitreous part of the wing, are yellow, and the 

 vitreous portion extends along the third discoidal cell to the hind 

 margin. On the hind wings the dark coloration at the base is 

 uninterrupted, but ceases at the anal nervure ; and that on the border 

 grows suddenly narrower below the discoidal nervure. 



Allied to Hylotoma concinna, but can hardly be the female of that 

 species.
