Temnojyteryx (1 species), Perifplaneta (1 species), Ilolocompaa 

 (1 species). It is remarkable to find the genera Ectohia and 

 Ilolocotnpsa existing side by side, for at the present day the 

 former genus is confined to the PaljBarctic region, whilst the 

 latter is essentially a tropical genus. Both the species of 

 Ectohia represented in the collection are allied to the recent 

 E. lapponica, L., and it is difficult to avoid the conclusion 

 that the genus was one of the few that were not driven from 

 Europe by the onset of the glacial epoch, or in other words, 

 E. lapponica appears to be a lineal descendant of the amber- 

 enclosed species E. haltica. Phyllodromia is now represented 

 in Europe by one doubtfully-indigenous species, but is repre- 

 sented by scores of species in the tropical and sub-tropical 

 regions of the world. IschnopUra and Temnopteryx are now 

 found in all regions of the world except the Palaearctic. The 

 collection affords still further proof, if any was required, that 

 the climate of Europe in Oligocene times was tropical or 

 sub-tropical. 



Living Blatta. — The President exhibited a living example 

 of Blatta found in bananas from Mexico. Mr. Shelford said 

 he thought the species to be Panchlora nivea, Linn. 



NuDARiA senex AND Calligenia miniata. — Mr. H. M. 

 Edelstbn showed a living larva of Nudaria senex, and living 

 larva and pupa of Calligenia miniata. He drew attention to 

 the clubbed bristles on the former as being incurved and most 

 curious ; and also to the hair tufts on the fifth segments 

 of miniata as being much darker than on the remaining 

 segments. 



Albinism in Epinehpble jurtina. — Mr. 0. E. Janson 

 exhibited a white aberration of Ejnnephele j^trtina, taken by 

 Mrs. Elliot in Holme Park, Sussex, in June 1904. The wing 

 coloration was entirely white, with the fulvous blotches on 

 the anterior decidedly bright and strong. 



Pvhinoceros bicornis followed by extraordinary CEstrid 

 FLIES {S2)athicera) mimetic of a large species op Salius 

 (Fompilidx). — Professor E. B. Poulton, F R.S., said that 

 when he visiteJ Stockholm last May in connection with the 

 Linnjean Jubilee, Professor Yngve Sjcistedt had shown him a 

 number of large Dipterous larva3 which he had obtained from
