50. Acrolophus arcei Druce. 
Anaphora arcéi Druce Ann-Mag. NH. (7s.) 7 442 (1901)’. 
The antennae of the ¢ of this species are serrate, and minutely ciliate ; the palpi overarch the thorax, and 
are roughly and distinctly tufted on each joint; the hind legs are hairy, except on the terminal joints of 
the tarsi. Genitalia: the uncus is somewhat angulate, double, with the points diverging, but the angle 
at the bend is rounded-off, not produced ; the claspers are dilated posteriorly, inverted at the upper angle 
of their apex, excavate on their posterior margin, and produced into a somewhat broad lobe at the lower 
extremity. .

51. Acrolophus uncispinis, sp. n. 
=* Anaphora punctata (p.) Druce Ann-Mag. NH. (7s.) 7 443 1901)’. 
Antennae serrate, yellowish brown. Palpi overarching the thorax, thickly clothed throughout; brownish 
fuscous, the brush on the basal joint brownish ochreous. Head and Thora brownish fuscous. Fore- 
wings with the ground-colour pale whitish ochreous, but almost completely suffused—except along and 
below the fold,and in a streak along the outer half of, and beyond, the cell—with fuscous, slightly tinged 
with purplish, on which are numerous small spots and strigulae of a still darker fuscous shade; the pale 
space below the fold is also somewhat sprinkled with these darker scales, and the plical patch is indicated 
by them on the fold, the other patches being obliterated and scarcely traceable; cilia pale dirty whitish 
ochreous, dusted with pale fuscous. Hap. al. 25-36 mm. Hindwings pale brownish fuscous, diluted to 
whitish ochreous about their base and on the cilia, through which runs a faint darker shade-line. 
Abdomen pale brownish fuscous: genitalia, uncus double, angular, the upper angle projecting to a length 
about equal with that of the lower point, and reaching as far as the ends of the claspers; these have 
their upper edge straight, but are dilated and rounded posteriorly beneath, terminating upward obtusely. 
Leys smooth; pale brownish cinereous,

The @ is larger than the ¢, with very hairy palpi, which extend rather more than 
the length of the head beyond it. This species is extremely similar to popeanella 
Clms. and to caprimulgus Wl1sm., but differs from both in the peculiar form of the 
uncus with its strongly projected upper angle.
