persecute the deer. As these insects are rarely to be seen in 

 collections, I have brought them here to-night for exhibition, 

 while, in order to make the exhibit moi^e complete, I have, 

 thiough the kindness of the President, obtained the loan of 

 two specimens belonging to the Hope Museum, Oxford, of the 

 third species. 



" The specimens exhibited are as follows : — 



"1. Pharyngomyia picta, Mg. — Though this species was 

 undoubtedly taken in the JSIew Forest by the old entomologists, 

 it has now probably ceased to exist there, owing to the practical 

 extinction of the Red deer in that locality. Whether it exists 

 in the country of the Devon and Somerset staghounds is 

 a question which still awaits elucidation. The specimens 

 exhibited to-night are without doubt of German origin, 



" 2. Ceiihenomyia rtijibarbis, Mg. — This species appears to 

 be common at times in Scotland, for I was informed by one 

 gentleman that he had seen as many as twenty specimens in 

 one day in the Glenfeshie Forest, Personally, I have only 

 met with six specimens, but, as these have been taken in 

 almost the extreme vertical limits of its range, it may be as 

 well to draw attention to the habits of the species under 

 these different conditions. On the slope of Cairngorm it 

 frequents the screes (steep slopes of loose stones), and slopes 

 of decomposed granite, between the 3000 and 3500 feet 

 contours, and there it rests basking in the hot sunshine. It 

 should be observed also that to seek this insect other than 

 during the briglitest sunshine is labour thrown away ! At 

 Golspie, at a considerably lower elevation {circa 700 ft,), it 

 was only met with flying over the heather, while to obtain it 

 one was obliged to look out for a herd of deer, and then to get 

 on the ground as soon as possible after the herd had vacated 

 it. With luck a specimen might be caught flying over the 

 heather, or might come and fly round oneself. It is, how- 

 ever, a method of collecting which entails a considerable 

 amount of walking, and is real hard work, as it has to 

 be carried on during the brightest sunshine. From our 

 limited knowledge of these two species it appears as though 

 Pharyngomyia jncta is the Southern representative of this 

 group of flies, while Cephenomyia rufibarbis is the Northern
