According to a manuscript note placed with the Mabira specimens by Mr. E. E. 

 Austen, this species is " closely allied to H. inornata, Austen, and essentially agreeing 

 with it in the shape of the frontal callus and of 1st joint of antennae : distinguished 

 by front being broader above, by third joint of antennae being larger and darker, by 

 differences in the wing-markings — light markings more sharply defined, those in discal 

 cell wider part, no darker areas at base and apex of discal cell or on fork of 3rd 

 longitudinal vein — by presence of only one distinct pale band on the hind tibiae, and 

 by greater length of 1st joint of antennae."

$. Head (lig. 7) : Jowls and lower part of face rather dark grey, with whitish hair ; 

 upper part of face, on each side of the antennae, light brownish ; between this and 

 the grey part a slight dark brown cloud ; a pair of dark brown spots immediately 

 below the antennae. Front blackish, more grey at the margins ; spots outlined with 

 brown ; short black hair towards the vertex. Median spot absent ; lateral spot 

 romided, almost in contact with the eyes. Frontal callus broad, shining blackish- 

 brown, nearly smooth, extending from eye to eye, its upper margin very convex. 

 Spot below callus blackish, indented from below in the middle. Antennae dull reddish 

 brown ; the third joint dark brown, except towards the base ; upper surface of first 

 joint also somewhat darkened ; first joint not much swollen, rather more than three 

 times as long as broad. Paljpi dark grey, clothed with rather short black hair ; tip 

 more brownish. Thorax dark brown, with pale markings arranged as usual, but quite 

 inconspicuous (the thorax is somewhat discoloured). Dorsum rather sparsely covered 

 with mixed short black hair and close-lying yellowish pubescence. Pleurae coloured 

 like the dorsum, but with a greyish dusting, and clothed with whitish hair. 



Abdomen dark, almost blackish brown above, dark grey beneath ; posterior margins 

 of tergites narrowly but distinctly light brownish-grey ; second tergite with, an 

 indistinct grey median stripe which does not quite reach the front margin. Pubes- 

 cence mainly black, but a considerable number of whitish hairs are present towards 

 the sides and along the posterior margins of the tergites. 



Legs : Front legs blackish brown, the tibiae with a rather broad white ring at the 

 base ; coxae with long white hair, pale ring on tibiae with shorter white hair, other- 

 wise the pubescence is entirely black. Middle legs dark brown, tibiae with two not
