b. £. rossiz (Fig. 37). This is identical with 
H. ero. The clasp is very lke that in the following 
division, but with a remarkable zigzag bend in the middle ; 
it has the head clothed with quite a helmet of spines, as 
in £. hewitsonit. The sickle, however, at once distinguishes 
it, the side-processes being of the ordinary form. I have 
had the advantage of seeing the appendages of the type 
specimen, temporarily i in Mr. Elwes’ possession. 
c. The next three forms are very close to- 
gether, having very similar clasps and very similar tegumina 
(sickles) with the lateral processes expanded into racket- 
shaped ends. So close are they that at first I thought 
they were probably forms of one species, and I am not 
certain that that may not ultimately prove to be the 
case; they are at any rate well-marked local forms, and 
must for the present at least be regarded as good species. 
The upper surface of HL. embla and cyclopius varies to 
forms that are almost identical; I have not seen forms 
intermediate as to the lower surface—still cyclopius has a 
pale band, whose outline may be detected in embla, where 
the pale colour has dwindled to two spots. Intermediate 
forms, and so-called hybrids between embla and disa, also 
occur. LH. cyclopius is unrelated to Z. edda or the Callere- 
hiv, which it much resembles in wing pattern. 
1. #. embla (Fig. 38). This form has much 
the longest clasp, as 6 to 5 in disa and cyclopius, with 
very large spines which run but a short way along the 
neck. 
2. E. cyclopius (Fig. 39). This has a rather 
shorter clasp, as 5 to 6; the spines are rather smaller and 
run more than half way to the base. 
3. EL. disa (Fig. 40). This clasp is much 
hike that of cyclopius, but is shorter and thicker through- 
out. 
Group VII. £. medusa, LE. hewitsonit. 
1. H. medusa (Fig. 41). In some respects 
this would come near L. stygne, especially in view of the 
form of clasp found in some German specimens I have. 
They exhibit a distinct neck, slightly curved, and carrying 
a rounded head with a circuit of spies. I hardly think 
these specimens represent a form entitled to specitic rank,
