12(5 CH ABU AT A. By Dr. M. Draudt. 
Ch. calva sp. n. (18 1) forms the transition between fistula and mutina ; it is reddish-grey with a 
slight litharge lustre, in the basal area at the proximal and costal margins strewn with greyish-white; the trans¬ 
verse lines as well as the ring-macula and coniform macula like in fistula little prominent, very fine, the posterior 
line dentate; the reniform macula is oblong-oval, orange-yellow, below there are 3 small thick white spots annexed 
in the shape of a trefoil-leaf; undulate line formed of single, scattered, blackish small scales. Hindwing brownish- 
grey. According to two couples from Mexico (Tehuacan, Puebla), taken by R. Muller in September; type 
in the Coll. Draudt. — In the form apyrina form. nov. (18 1) the 3 white dots are absent in the lower half 
of the reniform macula; according to 1 $. 
Ch. mutina Schs. (19 a) is similar to calva, dull brown, equably densely and coarsely strewn with 
white, so that the markings are almost entirely covered and generally only to be discovered with a lens, the 
posterior transverse line is, if it is distinct, less dentate than in the preceding; reniform macula in the upper 
part yellowish-white, often divided by 1 or 2 transverse lines of partition and below with 3 thick white guttae 
in the shape of a trefoil-leaf as in calva, of which one or the other may also be absent; undulate line lighter 
than the ground. Hindwing whitish with brown veins, marginal and discal spot. Mexico (Orizaba). —- In 
andabata form. nov. (19 a) the whole reniform macula is absent with the white spots. 
Ch. rectinubila Dyar (= $ mutina limps, pro parte) (19 a). Forewing dull greyish-brown, densely 
and coarsely strewn with white with similar transverse lines as in mutina, the posterior line entirely undentated 
and behind it a lighter band extending downwards directly from the apex and ending right in front of the proxi¬ 
mal angle; anterior transverse line double, almost straight, both lines separated afar, filled up with a slightly 
lighter colour; instead of the reniform macula only an insignificantly lighter streak on the transverse vein. 
Hindwing brownish-grey, towards the margin somewhat darker. Mexico (Orizaba, Zacualpan). I presume 
that Hampsons description and figure of the $ of mutina refer to rectinubila. 
Ch. griseago Dyar is very similar, smaller, light grey, strewn with whitish, all the markings quite 
extinct with a whitish, faded, indistinctly double shade extending from the apex to the distal quarter of the 
proximal margin, behind it a dark shade, the marginal area somewhat darker; at the cell-end a lighter spot. 
Hindwing grey, in the disc lighter. Expanse of wings: 28 mm. From Mexico (City), taken in July by R. Muller. 
Ch. iota Dyar (19 a) looks almost exactly like Hyclroeciodes ruxis (18 e), but the colour is somewhat 
darker, more violettish chocolate-brown, the transverse lines are clearer and more distinct, the posterior line 
is slightly bent, quite undentate. Mexico (Zacualpan). 
Ch. sygcleta Dyar is loam-coloured brown, dusted with reddish-brown, the costal margin and the 
filling of the indistinct double transverse lines somewhat lighter, in the narrow marginal area and the fringes 
blackish; at the base a blackish longitudinal ray, the ring-macula is light with a black central dot, the reniform 
macula narrow, elliptic, encircled and pupilled with black, distally white with a continuation at the middle 
radial branch. Hindwing dirty whitish, on the veins and apical border broadly blackened: Expanse of wings: 
24 mm. Mexico (Zacualpan) in September. 
Ch. chipeta Barnes (19 a) is very closely allied to fistula (181); it is distinguished by the white spots 
of the reniform macula; the distal part is straighter in its course, and from the lower part a continuation runs 
on the median proximad sometimes to below the ring-macula Avhere it ends pointed, being above and below 
distinctly defined with black; moreover the coniform macula is distinctly surrounded with dark, the ring- 
macula proximally pointedly extended; the cell is usually filled up with a somewhat darker colour. From 
Colorado. 
Ch. endiva Sm. (19 a) resembles chipeta in the marking, but it is somewhat smaller and much darker, 
the markings are much more extinct and the white continuation of the reniform macula is much shorter. Arizona 
and New Mexico. — In vespera Barnes ct- Lindsey the white marking of the reniform macula is absent and 
replaced by black scales. 
Ch. inconspicua Grt. (= pectinicornis Sm.) (19 b). ForeAving deep smoky broAvn, strewn lighter, with 
rather inconspicuous broAAm transverse lines; ring-macula small, round, reddish-brown, encircled with black, 
with or without a black pupil, the oval reniform macula is in the distal half white, in the proximal half reddish, 
both colours separated by black scales; coniform macula indistinct. Hindwing brownish-grey, towards the 
base whitish with reddish fringes. Arizona. Hampson’s figure of this species is incorrect. 
Ch. velutina Sm. (== lutina Sm.) Forewing yellowish reddish brown, on the proximal-marginal 
vein striped purple brown with light yellowish transverse lines, the posterior line on both sides bordered with 
a darker brown; the ring-macula is encircled with yellowish, the reniform macula oblong black, laterally bor¬ 
dered with yellow; the irregular yellowish undulate line is proximally bordered by minute indistinct browm 
spots; marginal area lighter, fringes ferruginous red. Hindwing semi-diaphanous light pinkish-reddish, in the 
marginal area dusted Avit-h a brownish grey, fringes speckled pink and brownish-grey. Expanse of AA'ings: 39 mm. 
Described from Florida. 
Ch. nephroleuca Jones seems to belong to this place according to the description, but unfortunately 
the formation of the antennae is not mentioned. ForeAAung brown, in and beloAv the cell dusted with a darker
