Conopim:. 



353- Physocephala nigra, I)c G., Loch Assynt, 6th to T6th June 

 191 t. About half a dozen specimens on the hank of the 

 river Lonnen ; vide remarks on Gymnochata viridis. 



(Estrim:. 



354. Cephenomyia rufibarbis, Mg., $, Loch Assynt, 3rd June 1911 ; 



, Loch Assynt, 16th June 1911. These are unusually 

 bright-coloured specimens, and may represent a local 

 (Wester Ross) race; see remarks under head of Gymno- 

 chata viridis. 



355. Hypoderma diana, Brauer, Loch Assynt, 5th June 191 1. On 



the 28th June a puparium was found in a green mountain 

 meadow on the Lochinver side of the Canisp Mountain, 

 the ground round the spot where the puparium lay being much 

 soiled with droppings of deer. The puparium is undoubtedly 

 that of a Hypoderma sp., and this being admitted, it can only 

 belong to the present species. 



Tachinid/e. 



356. Gymnochceta viridis, Fall., Loch Assynt, 6th and 1 6th June 



191 1. A very interesting form, distinguished by its dark 

 colour, the presence of metallic lines on the dorsum of the 

 thorax, the reduction in width of the metallic border to 

 the frontal stripe, and the reduced metallic area on the 

 occiput. 



Contrary to the usual habits of this species (probably due 

 to the absence of trees round Loch Assynt), these two 

 specimens were taken sitting on the grass close to the edge 

 of the water, in a little bay on the west bank of the Lonnen 

 River, almost opposite the spot where the Inchnadamph 

 Hotel boats are moored. This bay is of some interest, as it 

 yielded Cephenomyia rufibarbis and PJiysoaphala nigra, in 

 addition to this species, and seemed to be on the route 

 followed by the deer when passing from the high ground to 

 the river. 



357. Exorista sp. inc., near E. agnata, Rond., Loch Assynt, 7th 



June 191 1, 6" and $. Mr Austen notes on these specimens 

 that they differ from Rondani's description of E. agnata in 

 the abdominal chgetotaxy, and in the length of the penulti- 

 mate joint of the arista.
