ORTHOSIA. By Dr. M. Draudt. 
puncticosta- P. puiicticostata Dyar is of a bright red-brown with 2 white costal-marginal spots as the beginning 
ta - of the transverse lines being only partly marked lighter, behind the distal line dark dots on the veins; before 
the apex there are at the costal margin 3 more small, fine, white strigae; the reniform macula is a small, 
dark spot with a light reddish ring. Hindwing light brownish-grey, the veins and margin tinted reddish, with 
a dark discal dot and a dentate marginal line. Expanse of wings: 30 to 32 mm. California, in February. 
addenda. P. addenda Sm. (23 e) is on the grey forewing strewn with a light yellowish brown, in the discal area 
strewn with black except the costal-marginal part; behind the dentate black transverse lines with black 
streaks in the veins, the maculae are very small, surrounded with blackish. Hindwing blackish-brown. 
The $ is dusted with carmine, in the discal area not darkened. From California. 
algala. P. algula Sm. is a very robust species, on the forewing of a deep brownish purple red, dusted with 
violettisli grey with mostly quite extinct markings; the discal area is often somewhat darker than the rest 
of the wing, the maculae occasionally in somewhat lighter rings, the transverse lines, in case they are present, 
double, the distal part of the posterior lines punctiform. Hindwing dull smoke-brown. Expanse of wings: 
34 to 38 mm. From British Columbia. 
achsha. P. achsha Dyar is marked the same, but the forewing is violettish-grey except the proximal half of the 
basal area and the greatest part of the discal area, both of which are purple red-brown; the maculae are separate, 
narrowly surrounded with light, the two transverse lines are double. Likewise described from British Columbia . 
hepatica. P. hepatica B. & McD. (23 e). Forewing purple grey, dusted with reddish, with quite indistinct 
markings: transverse lines single, behind the distal line dots on the veins, the maculae represented by some¬ 
what darker small spots, the ring-macula being merely a dot; the marginal area is slightly darkened and the 
extreme costal margin rosy red. Hindwing smoke-grey with pinkish fringes. Expanse of wings: 34 mm. Ari¬ 
zona. It is to be separated from the very similar transparens (32 f) by the strongly combed antennae. 
ferrirena. P. ferrirena sp. n. (23 g) has violettish-grey forewings, the markings marked by accumulations of 
deep purple red-brown scales: the transverse lines very fine, interrupted and double, behind the distal line 
another row of dots on the veins, the undulate line likewise marked by very fine, chestnut-brown small 
dots, with an antemarginal row of black internerval dots; the reniform macula is finely surrounded with 
a violettish grey and is situate in a large red-brown trapezoid spot on the proximal upper end of which there 
is a triangular, equally coloured costal-marginal spot, behind which there follow besides 3 red-brown small 
strigae and subapically a larger, quadrangular spot. Hindwing white, veins and margin very finely strewn 
with brown. 1 $ from Bogota (Colombia). 
transparens. P. transparens Grt. [— liamifera Grt., fringata Sm.) (23 f) entirely resembles hepatica, but it has 
only serrate antennae provided with ciliary tufts. Forewing light reddish-brown, strewn with blackish and 
particularly at the base and proximal margin suffused with carmine, the transverse lines rather indistinct, 
the posterior line marked by a double row of dots on the veins; the somewhat darker pupilled maculae are 
surrounded with light yellowish, the marginal area is slightly darkened. Hindwing brown with carmine-pink 
fringes. Washington; California. 
praeses. P. praeses Grt. (23 f) is extraordinarily variable and has the scantily white-strewn forewing changing 
from a light brown to purple black, with undulate transverse lines bordered with a brownish red and equally 
ringed triangular maculae, which are often contrastingly light, the reniform macula proximally bordered with 
black; the undulate line is proximally shaded with blackish. The blackish-brown hindwing is tinted pink. 
saleppa. California. —- The form saleppa Sm. (23 f) differs by its lighter ground-colour, the maculae are surrounded 
with a more blackish colour, the distal one being reniform, both more or less confluent, the central area at 
stigmata, the proximal margin very narrow. From British Columbia. —• stigmata B. <b Ben], is almost black with 
contrastingly yellow maculae and marginal area. 
dukinfieldi. P. duklnfieldi Schs. (23 g) is a larger species with plain, ciliated antennae; forewing pinkish-brown, 
strewn with blackish, with double transverse lines and dots on the veins behind the distal line, and between 
the whitish ringed maculae with a rectangularly flawed median shade; instead of the undulate line there is 
a row of small red-brown spots. Hindwing reddish-brown. Brazil (Sao Paulo). 
39. Genus: Orthosia 0 . 
This genus being also known as Taeniocampa Gn. or Monima Hhn. differs little from the very closely 
allied preceding genus, chiefly by the entire absence of tufts on the abdomen, as rvell as by the presence 
of a horny plate below the frons; the vertex and collar exhibit a keeled tuft, the prothorax and metathorax 
loose tufts. The range of about 15 species known from America extends over more northern regions; many 
species are also known from the palearctic region. Comp. Vol. Ill, p. 89 [Monima). 
mys. 0. mys Dyar (23 e) is on the forewing uni-coloured dark purple brown slightly strewn with grey, all the 
markings are entirely extinct. The whitish hindwing is tinted purple reddish, particularly towards the margin. 
calor amica . California. — The form caloramica B. <b McD. (= agravens B. db McD.) (23 f) is distinguished by the presence of 
a small dark spot representing the ring-macula, and of a broad moon-shaped shade representing the reniform 
macula subterminally there are traces of a double row of dots on the veins. The $ antennae are combed. Arizona.
