 borough Heath, near Corfe Castle, Dorsetshire, Dasijpoda 

 Jiirt'ipeSy abundantly ; and at the same locality, a beautiful 

 species of Odynerus, new to the British fauna; this insect 

 is described in the Catalogue of Hymenopterous Insects, 

 pt. 5, Vespidae, published by the trustees of the British 

 Museum. In the national collection are two specimens of 

 this wasp, supposed to have been taken in Polish Ukraine, 

 S. W. Russia, but the locality is not quite certain ; they were 

 taken by Dr. Dowler, who formed a large collection of 

 insects, whilst on a tour through Europe, the whole of which 

 he presented to the national collection in 1843 ; the descrip-

 clypeus to the emargination of the eyes ; a minute yellow 

 spot between the antennae at their base, and another behind
