between the hybrid males and females of both the parent species, but 

 only a very few eggs were laid by these females which subsequently 

 recommenced " calling." Perhaps the most interesting feature of the 

 exhibit is the great variability shown by the specimens comprising the 

 larger of the 1902 broods, compared with the remarkable uniformity of 

 the hybrid moths reared during the previous year. Such uniformity 

 appears the more remarkable if we remember the wide range of 

 variability shown by both the parent species, and that a very Avide, if 

 not the entire local, range may be found within the limits of a single 

 brood of either species. 



At the same meeting Mr, C. P, Pickett exhibited specimens of 

 Hi/ljKrnia Icncojihacaria and i'/iit/alia pcdaria, taken at Chingford on 

 February 14th. With regard to the resting-habit of the former species 

 he said it was somewhat curious. The bodies lay in a parallel position 

 to the cracks in the bark of the trees on which they were found, the cross- 

 markings of the wings in an upright position corresponding closely with 

 the lines of the bark. Their colour also harmonised remarkably well with 

 the surroundings. He also exhibited ova of Diiiioyplia rrrsicolura on birch 

 twigs. The parent moths paired at 1,20 p.m., on March 16th, 

 remained iit coptihi thirty-three and a half hours. The female then 

 commenced crawling about the cage to find some suitable place for 

 laying, and, on the introduction of some birch twigs, deposited thirty- 

 eight ova in ten minutes upon it. By the morning of the 18th she 

 had laid 171 ova, which were cream-coloured and shiny in appearance, 

 but after two or three days assumed the colour of the birch twigs upon 

 which they were placed near the buds. The female in the act of ovi- 

 position prefers to rest head downwards, and sometimes uses the hind- 

 most legs for arranging the ova. 



At the same meeting Dr. Frederick A, Dixey read a paper, 

 illustrated by lantern slides, " On Lepidoptera from the White 

 Nile, collected by Mr, Vi. L. S. Loat, F.Z.S. ; with further notes on 

 Seasonal Dimorphism in Butterflies." He said that the collection of 

 butterflies which had been made at intervals by Mr. Loat during his 

 tenure of ottice under the Egyptian Government, was of special interest 

 on account of the accurate data which accompanied the specimens, 

 Mr. Loafs collecting grounds were in the neighbourhood of Kaka, 

 about 11' N. lat. ; and of Gondokoro, about further south. The 

 meteorological conditions at the time of collecting were generally those 

 of the dry season, though at Kaka the rains were just beginning. 

 Most of the examples of seasonally dimorphic species belonged to the 

 " dry-season " phase, but there were some curious exceptions. 

 Perhaps the most remarkable of these was Teraadns ilaira, Klug, 

 specimens of which, caught in January, during the height of the dry 

 season, were of the full " wet-season " colouring, while some of those 

 taken at the beginning of the rains were much " drier," The large 

 proportion of I'iciiiuif to the whole number of captures was noticeable, 

 as also was the general likeness of the whole assemblage to the butter- 

 fly fauna of Aden ; the different forms of Liiiutas chri/siji/itis, for 

 example, were found by Mr, Loat all flying together at the same spot, 

 just as is the case at Aden, The collection brought to light no new 

 ispecies ; it contained, however, a single example of the male of 

 J'iitacoptcrijA' rcnatas, Butl,, of which only two specimens, including 

 the type, and both females, have hitherto been known to science. Mr.
