hard integuments, but probably still better. by emitting 
copiously when touched an ill-smelling acrid fluid. A new 
Flata, taken at Johannesburg, though found sitting in rows 
upon the stems of plants, could in no sense be said to resemble 
flowers, as was the case with some of its congeners.

SITARIS MURALIS AT OxForD.—Commander J. J. WALKER 
showed living specimens of the Heteromerous beetle Sttaris 
muralis, rediscovered at Oxford in 1903 by Mr. A. H. Hamm 
of the Oxford University Museum, and found rather freely 
during September 1906 and 1907, on old stone walls in the 
vicinity of Oxford inhabited by the Mason Bee, Podalirius 
(Anthophora) pilipes, on which it is parasitic in its early 
stages.

TRANSITION BETWEEN My Loruris CHLoRIS, Fapr., anp M. 
AGATHINA, Cram.—Dr. F. A. Drxry exhibited typical speci- 
mens of the African Pierines Mylothris chloris, Fabr., and JM. 
agathina, Cram. ; together with a long series of forms, transi- 
tional between the two, from the neighbourhood of the Victoria 
Nyanza. 
He remarked that he had previously called attention to the

[Ivi 
Uganda (Proc. Ent. Soc. Lond., 1904, p. xv). The present 
exhibit showed an uninterrupted transition, in the case of the 
males, from one form to the other. The females passed by 
almost imperceptible gradations from the brownish-orange J. 
agathina, with its marginal row of well-defined black spots, up 
to a form with whitish fore-wings and very pale ochreous 
hind-wings broadly margined in black, between which latter
