[M. Paul Dognin has kindly enabled me to compare the Type of hebes Dgn. 
(3 Micay, 6569 Drnt. Det. 1911) with guadratella Wkr. Walker records his Type 
of guadratella as a $ —it is a 2 with trifid frenulum, extruded ovipositor, and slightly 
ciliate antennae. There is some slight variation in the distinctness of the darker 
markings in the specimens examined, but hebes and quadratella appear to be sexes of 
the same species, agreeing in the dark cilia of the forewings becoming paler at the 
tornus, and in the colouration of the underside.—Drnt. | 
5. Gonioterma alsiosum, sp. n. (Tab. VI. fig. 33.) 
Antennae shortly biciliate ( 2); testaceous, the basal joint paler. Palpi: median and terminal joints about 
equal in length; very pale testaceous, the median joint darkened on the outer side. Head and Thorax 
testaceous, the tegulae with a bluish suffusion. Forewings with the termen slightly sinuate; testaceous, 
with a patch of bluish grey suffusion beyond the end of the cell (only apparent in some lights), not 
reaching the termen or costa; before it, at the end of the cell, is a single round blackish spot between 
veins 5 and 6; cilia smoky grey. Exp. al.35 mm. Hindwings tawny grey, pale ochreous along the 
costa; cilia shining, pale cinereous, with a rather ochreous shade-line along their base. Abdomen 
hoary greyish. Legs tawny grey.

6. Gonioterma melema, sp.n. (Tab. VI. fig. 34.) 
Antennae biciliate 1; testaceous. Palpi tawny testaceous, inclining to ochreous on their inner sides. Head 
pale ochreous. Thorax tawny testaceous. FPorewings tawny testaceous at the base, rather shining 
brownish ochraceous toward the costa and on the outer two-thirds, with three meandering transverse 
streaks of purplish grey; the first commencing on the costa at one-third and following a wavy course to 
the dorsum before the middle; the second from the middle of the costa, obliquely outward to the end of 
the cell, descending thence nearly straight to the dorsum beyond the middle ; the third half-way between 
this and the apex, less oblique at its costal origin, outwardly curved toward the termen about its middle, 
and approaching the second in its descent to the dorsum before the tornus—these streaks are very 
ill-defined; a somewhat distinct fuscous spot lies at the end of the cell, just within the angle of the 
second wavy line; an indistinct series of purplish grey dots follows the termen at the base of the shining 
testaceous cilia. wp. al. 22 mm. Hindwings dull brownish cinereous; cilia shining, brownish 
cinereous. Abdomen brownish cinereous. Legs pale brownish cinereous.
