in a hair-tuft; proboscis stunted, palpi porrect, below long-haired; male antennae long-combed, thorax purely 
clad with hair and exhibiting only behind a loose tuft; the tuftless abdomen is long-haired at the base, in the 
$ provided with a woolly anal tuft. Some rather large species, all from America, their larvae, as far as they 
are known, boring into species of Typha. 
B. obliqua Wkr. (= obliquata Grt.) (45 k) has light grey forewings strewn with brown, the discal 
area being darkened by reddish-brown; the very oblique anterior transverse line bends on the hindmarginal vein 
to the base, the posterior line is somewhat dentate, the obliquely placed reniform macula is somewhat more 
yellowish. Hindwing reddish brownish-grey. Canada to Florida and Colorado. — The larva is slender, black 
with a rough skin, and lives in Typha latifolia. — f. pallida. B. <f- Benj. (46 a) is considered to be the western 
race from Utah, but it may be a distinct species. It is a much lighter form, quite light yellowish-brown, the 
basal area whitish, the maculae centred with reddish, the median shadow quite absent, the hindwing slightly 
tinted with flesh-coloured reddish. — f. brehmei B. db McD., in contrast with pallida , is a somewhat smaller, 
square-built form with a less produced apex of the wing and a much deeper brown colouring, the median area 
intensely darkened, the basal area not being whitish; the hindwing is also darker smoky-brown. Described 
from New Jersey and perhaps also a distinct species. 
B. densa Wkr. ( = oecogenes Dyar) (46 a). Forewing reddish-brown, base of costal margin not lighter 
whitish but with a slight pink hue. the median area brownish, not contrasting, the elliptical reniform macula 
large, light reddish, centred with a redder colour, not so oblique as in obliqua , marginal area powdered with 
a darker grey. Anal wool in the $ white. Expanse of wings: 30 to 35 mm. Washington to Florida. 
B. garganlua Dyar (45 k) is a larger form with an expanse of 45 to 55 mm. Body grey with a dark 
brown mesothorax and black anal wool in the $; forewing in the basal area violettish-grey, not white, median 
area dark brown, the elliptical reniform macula is oblique, centred with reddish, the ring-macula is absent 
altogether, the distal transverse line is feeble, the marginal area is dark violettish-grey. California, bred from 
Typha latifolia, 
B. anoa Dyar (45 k) is likewise a very similar species, the fore wing dark reddish-brown, the markings 
obliterated by the irroration, the basal area only somewhat lighter, followed by a red shadow, the reniform 
macula centred with dark red. Hindwing brown, in the disk flesh-coloured reddish with a darker central spot. 
Expanse of wings: 50 mm. Florida. 
B. matanzasensis Dyar (45 k) is about the intermediary between obliqua and anoa, the shape of the 
wings being that of anoa , the markings those of obliqua , more reddish, the light basal area less contrasting, 
the median area broadly shaded with dark and with a distinct oblique median line as in anoa. Expanse of 
wings: 50 mm. An insular form from Cuba. 
B. pleostigma Dyar (45 k) is the most similar to gargantua. Forewing reddish-brown shaded with 
chocolate-brown, basal area flesh-coloured reddish, the maculae centred with a dull red-brown, the reniform 
macula above pointed, the median vein and its branches powdered with dark; the marginal area is powdered 
with purple grey with small darker sagittary spots. Hindwing brown, at the margin broadly darker. Expanse 
of wings: 52 mm. Mexico (Tabasco). 
B. gortynoides Wkr. { — vulnifica Grt.) (46 a). Forewing light red-brown, strewn with a darker colour, 
in the median and marginal areas more intensely so, between them greyer with brown transverse lines and 
maculae similar to the preceding species. Hindwing light reddish brown, strewn with a darker colour. The 
$ is more yellowish, the anal wool white. Canada to Florida. 
B. melanopyga Grt. (46 a) is very similar, but the median and marginal areas are not more prominently 
dark, the areas between them not greyer. Hindwing lighter, the female anal wool is black. From Florida. — 
Larva olive-grey, beneath lighter; it lives in water-lilies. 
B, diffusa Grt. (46 b) is the darkest species, on the ochreous-yellow ground intensely strewn with 
dark red-brown, in the median area powdered with red-brown, the reniform macula narrow and oblique. Hind¬ 
wing reddish greyish-brown, at the margin darker, anal wool in the $ dark brown mixed with grey. Canada, 
Maine. 
175. Genus: ,4i*c*IisisBsira Hbn. 
Separated from the preceding genus by a long triangular horny frontal appendage being bicuspid at 
the end, the male antennae not being pectinate, but only feebly serrate and set with ciliary tufts, and the 
tuftless thorax exhibiting an admixture of hair-like scales; the abdomen also shows a tuft on the first ring. 
As to further particulars about this genus containing several palearctic species, the larvae of which live in reed, 
cf. Vol. Ill, p. 236. 
A. oblonga Grt. (= permagna Grt., subcarnea Kell.) (46 b). Forewing light ochreous-yellowish, with 
a red-brown tint and strewn with a brownish-grey, with a darker striped median, with dots instead of the maculae, 
and a row of vein-dots instead of the postmedian line. Hindwing ochreous-reddish, in the disc powdered with 
brown. From Maine and New York to Florida, as well as in Jamaica. —- The slender brown larva lives in Typha.
