E. camina 8m. is the most closely allied to spinosae, but much smaller, less marked and without 
any red-brown tints, greyish-brown, basally and subterminally powdered with black, the reniform macula 
large, oblong, black; the undulating line is indistinct, whitish grey, the marginal area behind it smoky. Described 
from a $ from New Hampshire. 
E. mexicana Hamps. (49 f). Forewing on the yellowish ochreous ground olive of various shades, 
powdered with brown or red-brown, with light transverse lines and grey-centred maculae surrounded with 
light; before the sharply dentate light undulating line darkened. Hindwing orange-yellow with faded dentate 
reddish subterminal and terminal bands. Mexico. 
E. crenilinea 8m. (49 f) is on the forewing yellowish, marked with brownish ochreous, the darkest 
before the white dentate anterior transverse line, in a discal shadow and the reniform macula; the subterminal 
area is brownish, inwardly defined by the sharply dentate and distally black-eclgecl postmedian line. Hindwing 
light reddish-yellow, towards the margin darkened with coppery red. Texas. 
22. Genus: Meto|>o|»lacls Hmps. 
Separable from the preceding genus by a much larger round frontal projection with a small rough 
elevation in the centre and a horny plate below it; the short palpi are erect. The thorax is only hairy and tuft¬ 
less like the rough-haired base of the abdomen. The short anterior tibiae outside show a long bent horny sting 
and inside a short and a fine spine. Forewing below the apex feebly excised. Only 1 species: 
Type: M. olivata Hmps. 
M. olivata Hamps. (49 f). Forewing white with olive-green antemedian and median bands, the latter 
behind the cell confluent with an olive-brown spot; behind the dentate white postmedian line with an olive- 
green costal-marginal spot extending below the apex to the margin, and another one below the centre. Fringes 
white speckled with green. Hindwing white with a broad faded brown subterminal band. Brazil (Matto Grosso). 
23. Genus: Hemigrotella B.u.McD. 
The only small species with comparatively long and narrow fore wings has short, slanting, scaled palpi 
and a but feebly rounded frons. Thorax clad with smooth scales. Anterior tibiae with a single strong horny 
sting at the end, without spines. 
Type: H. argenteostriata B. & McD. 
H. argenteostriata B. & McD. (49 f). Forewing ochreous with a silvery white costal-marginal streak 
and a broad long silvery spot from the base to the apex which is divided by 2 longitudinal stripes of the ground¬ 
colour into 3 silvery spots. Hindwing white, feebly smoky, in the ^ darker. California. 
24. Genus: €»roteSls® Harv. 
This difficult genus comprises to-clay quite a number of small mostly white very similar species. Whereas 
in 1903 only two species were known, to-day the number has increased to 14. The short palpi with a porrect 
bare terminal joint; on the frons there is a large ,,ring-wall“ with an obliquely truncate, above excavated 
central projection in it. Anterior tibiae inside with a long curved horny sting and 2 slender spines, outside 
a shorter horny sting. Dr. Barnes and Benjamin published an excellent revision of this group. 
Type: G. septempunctata Harv. 
G. septempunctata Harv. (49 f) has pure white forewings with a silky gloss, the base of the costal 
margin is black, and there are 3 antemedian and 4 postmedian black dots. The white hindwing is occasionally 
apically brownish. Texas, Colorado. 
G. harveyi B. <£.• Benj. (49 f) is likewise purely white, spotted as the preceding species, but the spots 
are thicker and more intense, besides with 2 small basal spots, one of which is occasionally also traceable in 
septempunctata. Hindwing more intensely darkened. The species is somewhat larger and occurs in Colorado. 
G. sampita Barnes (49 f). Spotted as harveyi, but besides with a series of small black spots in the 
base of the fringes. Hindwing greyish-brown, basally whitish. Smaller than harveyi. From Arizona.
