Rare and Blind Beetles. — Mr. G. C. Champion exhibited 

 specimens of Dromius angtostus, Brulle, and Cryptophagus 

 l<j)vendali, Ganglb., recently recorded by him from Woking 

 and the New Forest respectively ; also two species of the 

 Staphylinid genus Leptotyphlus and one of the Cui-culionid genus 

 Alaocyha, calling attention to the fact that these extremely 

 minute blind South-European insects were much smaller than 

 any known British representatives of the groups in question. 



Rhopalocera from the Canaries.— Col. C. Swinhob ex- 

 hibited several boxes of butterflies taken by him during the 

 present year (1908) in the Canary Islands, chiefly from Grand 

 Canary and Teneriffe. They included amongst others Pieris 

 rapse, showing a tendency to lose the black spots on the upper 

 sides of the wings, P. brassicee var. cheiranthi, Hb., P. dapUdice, 

 Gonopteryx cleobule, Chrysophamos phlxas, Vanessa atalanta (a 

 rare species in the islands), V. indica, var. vidcania, Godt. 

 (common), Pyrameis cardui, Golias edusa, Argynnis pandwa, 

 A. lathonia, Pararge xiphia, var. xiphioides, Stgr., Epdnephele 

 jurtina, var. Mspidla, and Lampides ivebhianus, the one butterfly 

 peculiar to the islands. He observed that with the exception 

 of the last-mentioned all the species met with suggest a 

 foreign origin.
