and feeds upon the ant larva;. The imago on eiuei'gence from 

 tlie pupa is clothed with scales highly distasteful to the ant, 

 which thus protect it from attack during emergence, and 

 until such time as it is able to fly, when the scales drop off.

Papers, 



Mr. G. C Champion, F.Z.S., read a paper on '' An Entomo- 

 logical Excursion to Bejar, Central Spain." 



Mr. Edward Saunders, F.R.S., F.L.S., communicated a 

 paper on " Ilymenoptera Aculeata collected ))y the J\q\. A. E. 

 Eaton, M.A., in Madeira and Teneriffe, in the spring of 

 1902." 



Dr. Frederick A. Dixey, M.A., M.D., read a paper, illus- 

 trated by lantern slides, " On Lepidoptera from the White 

 Nile, collected by Mr. W. 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 office under the Egyptian 

 Government, was of sj^ecial interest on account of the accurate 

 data which accompanied the specimens. Mi-. Loafs collecting 

 grounds were in the neighbourhood of Kaka, about 11" N. lat. ; 

 and of Gondokoro, about 6" further south. The meteorologi- 

 cal 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 ex- 

 ceptions. Perhaps the most remarkable of these was Teracolus 

 daira, ivlug, specimens of which caught in January, during the 

 height of the dry season, were of the full "wet-season" colour- 

 ing ; while some of those taken at the beginning of the rains 

 were much '' drier." The large proportion of Pierlns: to the 

 whole number of captures was noticeable, as also was the 

 general likeness of the whole assemblage to the butterfly fauna 

 of Aden ; the different forms of L. chrysippus, 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 species ; it contained, however, a single example of 

 the male of Plnacopteryx oenatus, Butl., of which only two
