ancestor but not of the other form. The conclusion from 

 Col. Manders' experiments therefore was that if ckrysippus and 

 dorippus are geographical races and not dimorphic forms 

 doripjius is the essential form, if they are dimorphic forms 

 similar experiments with dorippus should yield specimens with 

 some definite ckrysippus aspect.

A Coleopteron new to Britain. — Mr. Donistiiorpe ex- 

 hibited a specimen of CcUops montivagus, Heer, new to the 

 British list, taken at Nethy Bridge, on June 27 last, under a 

 dead squirrel. Also C. tristis, Panz, for comparison, the nearest 

 species previously known as Bi-itish. 



Three families of P. dardanus, Brown, bred from 

 HiPPOcooN, F., females in the Lagos district by W. A. 

 Lamborn. — Professor Poulton exhibited the first of these 

 families and a part of the second. He stated that these three 

 families were the first successful attemj^t, outside Natal, to 

 breed P. dardanus from a known female parent. In the 

 Durban district the form cenea had always predominated in 

 the female offspring bred from a hippocoon parent, while in 

 the Lagos district the female offspring of hippocoon were 

 themselves always hij)pocoon in all three families bred by 

 Mr. Lamborn, — a result which harmonised with the presence 

 oi Aviauris niavius^ L.,the model of hippocoon, and the absence 

 on the Nigerian coast of all the other Natalian Danaine 

 models of the female dardanus, except Danaida ckrysippus, L.
