THE EGG OF LIPHYRA BRASSOLIS. 49 
The egg of Liphyra brassolis. 
(With two plates.) 
By T. A. CHAPMAN, M.D. 
I know very little of the eggs of exotic Lycenids, and therefore it 
goes for very little that I am unable to place the egg of L. brassolis as 
at all in line with any other Lycenid ege that I have seen, still the 
remarkably isolated position of Liphyra in relation to other Lycenids, 
makes it not at all unlikely that this difficulty of classifying the eee 
does arise, not simply from my narrow outlook, but because it is really 
in accord with the facts. 
It would be only after some examination that one would conclude 
that they were Lycenid, and probably nearer to Theclids than to any 
other subfamily we know much of. 
It is a very large egg, 1:-45mm. in diameter and 0:94mm. high. 
Seen from above, it is circular; and viewed laterally, the sides are 
broadly, vertical, in fact, in a detail to be mentioned immediately, 
it is wider at top than at bottom, still speaking broadly, it has the 
form of a portion cut off a cylinder, 1.45mm. thick and of a length of 
094mm, 
The material under observation being three whole (but of course 
dead, not simply unhatched, but without any embryonic development) 
eggs and six that had hatched, any statement of colour may be very 
wide of the truth, as regards the fresh living egg. 
Seen from above, the upper flat surface has a dark brown margin 
about 0°3 mm. wide, inside that, quite a pale ring of equal width, with 
a central, still paler, circle, 0°2mm. in diameter; this is the rather large 
micropylar area. laterally, the same brown area seen on top, oceupies 
0-36mm. of the upper part of the sides, and the lower 0:-6mm., is pale, 
probably white, in the living egg. 
Diagrammatic vertical section across middle of egg. About x 25. 
Returning to the form of the egg, and taking it as a portion of a 
cylinder, we find the upper margin has, as it were, a roll of material 
laid over it. 
I have endeavoured to show this in the diagrammatic vertical 
section of the text block. 
Describing this along with the photographs, pl. II., giving vertical 
views of the egg after dividing it horizontally at the level of B, the lower 
portion A to B viewed from above in pl. IL., fig. 2, is vertically ribbed, 
as suggested in block, in the figure the upper ends of these ribs are 
seen as angular projections all round, These ribs are a little waved, 
not absolutely straight, and in some case actually anastomose. Their 
number may be judged from the photograph, they appear not to be
