lemur of the hind leg. The tibia has short stout bristle-like 

 hairs, and still remains attached to the tarsus, of which three 

 segments can be disthiguishcd. Of the hind leg, the femur, 

 tibia, and a small j>ortion of the tarsus are distinguishable. 

 The femur is twice as l)road as the tibia, and is now flattened. 

 The tibia appears to be a well-rounded structure, (if even 

 diameter throughout, and clothed with numerous short stout 

 bristle-like hairs. 



Affinities. — The general characters of the wings are clearly 

 those of the genus Phylloblatta, and the relationship to V. 

 reniforniis, Handl., is somewhat close. From that species how- 

 ever, the wings differ in the character of the median vein. The 

 latter vein does not divide until a point beyond the middle of 

 the wing has been reached, and its branches arc few in number, 

 whereas in P. rcuiformis, the median divides before the middle 

 of the wing is reached, and the branches are at least twice as 

 numerous. The character of the sub-costa, radius and cubitus 

 is much similar. The anal veins are more numerous in F. 

 reniforniis than in this specimen. As my work upon fossil 

 Ijlattoids has increased, I have become impressed with the 

 variability of the wing venation, and am convinced that when 

 it is better understood, it will be necessary to merge several 

 now recognised species into one. Whether this specimen must 

 ultimately be classed as an example of I-Iandlirsch's species, 

 P. reniforniis, it is not possible to say. For the present it seems 

 desirable to mark its differences by the creation of a new species. 

 We therefore style it P. obs citrus.

Species diagnosis. — Radius confined to outer half of wing, 

 relatively feeble; radial sector large, much branched; branches 

 of median occupy whole of outer half of inner margin. Anal 

 area extending over one-third of length of wing. 



A thin dark grey slab of shale bears upon its surface two 

 wings, the right underlying the left and destitute of the anal 

 area. The right wing has also the underside uppermost. The 

 U^ft wing, which is almost perfect, lacks only a little of the 

 apical margin, and the inner end of the sub-costal lobe. It 

 lies at right angles to that of the right, and overlies the inner 

 third of it. The venation of both wings is clearly defined. 



The outer margin of each wing is gently convex, the apex 

 bluntly rounded, and the inner margin almost straight. The 

 general form is that of "an elongated oval. The length is 

 42mm., in both wings; the greatest breadth is across the left 

 wing, just behind the anal area where it is ig.5 mm.
