C. elongata Mschlr. (36 i). This little species, looking almost like a Nola, has the forewing yellowish- 
white mixed with grey, with a dark discal dot and two indistinct darker transverse lines, and a subterminal 
row of brown dots. Hindwing white, in the marginal area yellowish. The $ is strewn with darker scales behind 
the transverse lines. Porto Rico. 
57. Genus : ISoucln Dyar. 
Proboscis stunted, frons without projection thorax chiefly clad with scales tuftless like the abdomen. 
Porewing with an accessory cell. Two small species from Mexico have been described: 
B. pallipars Dyar (42 a). Porewing grey, in the basal area broadly and conspicuously greenish-white, 
with black single dentate transverse lines, the two anterior ones on the submedian fold proximally dentate; 
at the end of the faded coniform macula a white dot, the ring-macula is likewise a white black-edged dot. the 
reniform macula is composed of two white dots with a black spot behind it; the undulate line is an irregular 
dark shadow. Hindwing dark grey. Mexico (City). 
B. hidalgonis Dyar (42 a) has light green forewings with similar black transverse lines as the preceding- 
species, the anterior line is connected with the black-filled coniform macula, the ring-macula is a black dot. 
the reniform macula is large, irrorated with dark, with two white dots on the proximal edge; behind the irregular 
undulate line there are black marginal spots. Hindwing dark grey. Mexico (Hidalgo). 
58. Genus: Protliriuax Hmps. 
Proboscis stunted, palpi very short; frons with a long bicuspid projection and a large triangular horny 
plate below it. Thorax clad with scales, metathorax with a tuft turned backwards, shoulder-covers posteriorly 
up-turned. Neuration as in the preceding. But one species. 
P. luteomedia Sm. (36 i). Forewing greyish-white, strewn with blackish-brown, with a yellowish 
tint from the base of the costal margin below the cell to the subterminal line and from there inwardly upwards 
oblicpiely to the apex; the transverse lines are quite indistinct, the anterior line is double; coniform macula 
surrounded with red-brown, the two upper maculae whitish, centred with brownish, reniform macula on the 
median inwardly produced; the whitish undulate line only commences in the middle close at the distal margin 
and is proximally bordered with red-brown; the apex is parted by black. Hindwing white, on the veins brownish. 
Arizona. 
59. Genus: Crimoiia Sm. 
Very near to Prothrinax, separated by the developed proboscis, with somewhat longer palpi and a 
semiglobular frontal projection. The tuftless thorax is covered with rough broad scales, the shoulder-covers 
are not bent upwards, the two first abdominal rings exhibit small thin tufts. But one species. 
Cr. pallimedia Sm. (36 k) has yellowish-white forewings with a slight ochre-brownish admixture, 
at the hind-margin and distal margin greyish-white, with single rather indistinct transverse lines and a large, 
triangular, white and grey costal-marginal spot containing the maculae which are finely encircled with black. 
The light undulate line is on both sides broadly shaded with brownish. Hindwing greyish-white. California. 
60. Genus; Kiilbia Steph. 
To this slenderly built Noctuid genus of the palearctic region also two American representatives have 
been reckoned of late. As to further details cf. Vol. Ill, p. 204. The proboscis is present, the frons smooth, 
the thorax entirely clad with scales, with a loose tuft on the metathorax. 
St. fotelloides B. <£■ McD. (36 k) externally entirely resembles an Oxycnemis from which it is easily 
discernible by the smooth frons and the unarmed anterior tibiae. Forewing grey, in the basal area white with 
a blackish and yellow admixture with black transverse lines, the anterior line double, and with large grey maculae 
in white rings and encircled with black, also the coniform macula is present; from the reniform macula a whitish 
patch extends to the apex; in the uniformly grey marginal area there is the darker undulate line. Hindwing 
diaphanous white, at the costal and distal margins smoky grey. Arizona. 
St. apposita B. da McD. (36 k) is much larger than the preceding and resembles St. anomala (cf. 
Vol. Ill, p. 204, pi. 42 e). Forewing dark grey, in the costal half of the median area and subterminally shaded
