BRITISH MOTHS 



NUMERIA, DupONCHEL. 

 This genus has the wings large, rounded, and entire ; the disc very strongly atomose, and with a broad 

 central dark bar. The antennte of the males are bipectinated ; the palpi are short and obtuse : the spiral tongue 

 short ; the caterpillars are long, slender, and attenuated in front, with the head notched and the hinder segments 

 tubercled. 



Species 1. — Ncmeria pulvebaria". — (Plate LXI., Figs. 11, 12.) — This species measures from l^to rather 

 more than 1^ inch in expanse ; the wings are of a buff-red colour, very thickly powdered with dusky atoms, 

 and with a broad central dark-brown bar of variable form and extent, of which the basal edge is straight and 

 transverse, and the outer one very irregular ; the hind wings with an obsolete dusky striga running from the 

 anal margin. The caterpillar is reddish-brown with straw-coloured streaks ; the terminal segments more varied 

 ■with the latter colour and dark tubercles. It feeds on various forest-trees, and the moth appears at the 

 beginning of June, and is rather common in woods.

CABERA, Treitschke (ex parte). 

 This genus has the antennas bipectinated nearly to the tip : the palpi are short, scarcely extended above the 

 clypeus ; the wings are delicate, entire, pale, thickly pulverose, and with simple strigse. The caterpillars are 

 long, slender, and smooth, with two minute spines on the anal segment. Several of the species appear to be 

 double-brooded. 



Species 1. — Cabera pusaeia ^ — (Plate LXI., Figs. 13, 14.) — This species measures about 1^ inch in 

 expanse ; the wings are white, freckled with minute dusky atoms, and with three equidistant, very slightly 

 waved dusky striga, of which the second and third extend across the hind wings : these strigse are however 

 more or less obsolete, and vary slightly in their juxtaposition. The caterpillar is green, with the anterior 

 segments and a dorsal spot on each of the following of red-brown, the latter edged with white. It feeds on 

 various forest-trees, and the moth appears in May and again in July or August, and is very abundant in woods.

 Aurelian, pi. 44, fig. h. PhaliBna striffata, Scopoli. 



Species 2. — Cabera eotundaria ^' — (Plate LXI., Fig. 15.) — measures li inch in expanse; the wings 

 are rounded and white, slightly irrorated with dusky atoms and with two slightly undulated dusky strigse 

 extending across the wings, the first of which is geminated in the fore wings. Probably a variety of the 

 preceding, as that differs in the juxtaposition of the strigas, on which the present species seems chiefly to rest for 

 its claim to be considered as distinct from the preceding.

Species 3. — Cabera exanthemata ''. — (Plate LXI., Fig. 16.) — This species varies from 1 to 1;^ inch in 

 expanse. The wings are of a dirty white colour, with a buff tinge much sprinkled with pale brown atoms, 

 and with two slender strigse of the same colour, which cross all the wings, the anterior pair having also a third 

 striga nearer the base, which is, however, sometimes obsolete or more or less confluent with the middle one (G. 

 approxiraaria, Haw.) ; when more thickly atomose, they form the G. arenosaria, Haw., which has sometimes the
