128 Psyche [Sept.-Dee 
resembling a garland more or less raised and thickened at both 
ends. Very thin and faint in weakly pigmented form. 
2. The inner triangle: a fuscous triangular basally tapering 
mark formed upon the termination of each vein (mainly from 
M 1 to Cu 2 ) by the meeting of the thickened prgeneural ends of 
two adjacent sections of the terminal line. Not necessarily 
absent in weakly pigmented forms. See also IV, 3. 
3. The outer triangle: a fuscous subtriangular distally taper- 
ing mark formed upon the proximal part of the terminal cilia 
(and also occurring sometimes upon the vadosal fringe of the 
upper side) independently from the general pigmentation, if 
any, of the latter and placed directly opposite (base to base) 
the inner (or the vadosal) triangle, which it repeats in reverse, 
except that its base is usually narrower and its point more or 
less truncated. Mainly in hindwing. Seldom leading to any 
conspicuous scuttelation in the forewing. 
VIII. Maculation of underside. 
Counting from termen basad a first macule (split into inner 
and outer part) and a second macule are both represented in 
Sc., Rs, and 2A of hindwing, in R 3 (where, however, they occur 
seldom and are always much reduced) and R 4 of forewing, and 
in M 1? M 2 , M 3 , Cui, Cu 2 , and 1A (small in the two last) of both 
wings. A third macule supplements the set in Sc and Cu 2 of 
hindwing. Moreover, there is a small lateral macule in 4A of 
hindwing caught in the blind alley of the dorsum and sometimes 
a small lateral macule is somewhat similarly trapped in R 2 of 
forewing (where the eye sees it as “belonging” to the transverse 
series of second macules). In both wings the discoidal cell (a 
double interspace R and M) has its own first (double) discoidal 
macule , 13 the rheniform RM, traversed by the discales (the outer 
segment of its R part and the outer segment of its M part form 
in relation to the second macules M 1 and M 2 a pair of sessile 
third macules — an important point in the case of certain other 
genera). In the hindwing there is a second (single) discoidal 
macule within the cell under the scar of vein M. All the macules 
are of a more or less deep fuscous and are rimmed with struc- 
tural scales, i.e ., halos (produced by the macule having drained 
during its period of formation and concentration the initial pig- 
13 Among the names employed by authors for this double macule are “discal 
streak,” “bar,” and “disco-cellular lunule.”
