A medium-sized but rather slender black species, with a long 

 linear deep blackish castaneous frontal callus on the very norrow brownish 

 frontal stripe, with the almost unicolorous blackish abdomen not banded, 

 and with the blackish brown wings. 



Female. Head broader than the thorax, moderately arched 

 behind. Frontal stripe very narrow, gradually contracted from the 

 vertex to the lower end, and wholly seven times as long as its broad- 

 est part or wholly thirteen times as long as its narrowest part, pale 

 brown but the lower part slightly ashy greyish, covered with numerous 

 very short inconspicuous black pubescence which becomes much sparse 

 at just above the callus proper and then hardly extends below to the 

 lower margin along its sides ; frontal callus shining deep blackish 

 castaneous, long and narrow, not touching the eyes, wholly three times 

 as long as wide, with the lower end rounded and with the upper top 

 more- or less notched and bearing a lineal prolongation which is about 

 three times as long as the callus but its upper thirds is quite dusted 

 though it is distinctly keeled, and which is not extending to the 

 vertex ; vertex greyer, covered with numerous erect black pubescence 

 which is slightly longer than that on the frontal stripe and is some- 

 what curved, and bearing very inconspicuous ocelli. Frontal triangle 

 brownish yellow-grey, very slightly raised from the eye-margin below, 

 with a very few but rather distinct entire median sulcus and with the 

 more brownish tomcntose double lunules just above the antennal 

 fossae. Face grey tomentose but the .upper corner of the cheeks 

 yellowish brown, this colouring extending below along the eye-margins ; 

 cpistoma much broader than it is long, covered with some short but 

 rather conspicuous blackish pubescence on the lateral upper corners
