!944] Genus Ly cosides 121 
wing pattern as a whole, still I am quite sure that it would be a 
waste of time to try and twist this or that illusion created by 
a transverse combination of Lycsenid macules into this or that 
“prototypical line.” 
The wing-characters of the genus Lyc^eides 
The categories to be discussed are: I. Size and shape. II. 
Ground. III. Cyanic overlay. IV. Vadosal elements. V. Scintil- 
lant elements. VI. Hairscales. VII. Terminal submarkings. 
VIII. Maculation. (Number of specimens of Lycoeides forms 
examined: 959). 
I. Size and Shape. 
Length of forewing (from base of Cu to end of M x ) in small- 
est individual measured: 7.5 mm., with length of hindwing 
(from base of Cu to end of M 2 ) : 6.5 mm.; in largest individual 
measured these lengths are: 18.5 and 15 mm. respectively, thus 
giving a range of 11 mm. and 8.5 mm. Number of scale lines 
ranging from 140 in forewing and 115 in hindwing to 260 and 
210 respectively. In average sized forms the number of scale 
lines varies from 190 to 2 10 in the forewing and from 160 to 170 
in the hindwing. The hindwing varies less than the forewing in 
the number of scale lines but more in shape. The most distal point 
of the termen of the hindwing lies either rather anteriorly ( high 
angled shape), namely between M x and M 2 , or more posteriorly 
{low angled shape), between M 2 and M 3 , or rather exactly at 
the end of M 2 {average shape) ; or the termen is evenly rounded, 
i.e., runs almost concentrically to the scale lines in the stretch 
from M x to Cu x this however only occurring in stunted indi- 
viduals. In especially high-angle individuals the scale line 
which in the hindwing coincides with the tip of Cu x (further 
on termed s.l.Cux) abuts anteriorly at the tip of Rs and 
cuts off a terminal segment of about 20 scale lines at the 
point of its greatest expanse (in interspace M 2 ) ; but an- 
other individual with the same number of scale lines in M 2 will 
seem less conspicuously angled if s.l.Cux reaches anteriorly a 
more distal point (say, between Rs and Mi) since the segment 
cut off by the line will occupy a lesser number of scale lines. 
In low-angled forms s.l.CUi may abut at M 1? thus cutting off 
the terminal parts of only two interspaces instead of four. Fi- 
nally the segment itself may be either of a fuller or more apical
