108 PROCEEDINGS OF THE 



Y. — On some New or Rare Hymenoptera, By Mr. Peter Cameron. 



The species described by the author included Limneria fusipes, 

 Holmgren, from Sutherlandshire ; L. vestigicdis, Ratz, bred from 

 galls of Nematus gallicola — both additions to the British lists; 

 L. flaviventris, Ratz, bred by Dr. B. White, from fir cones 

 inhabited by Eupitecta togata, near Perth ; Torymus azureus, 

 Boh., bred from the same fir cones by Dr. White; and T. caudatus, 

 Boh. (sec. Thomson), bred from fir cones collected by Mr. J. E. 

 Fletcher, near Worcester, gathered to see if they would yield 

 Coccyx strobilana. T. caudatus differs from azureus in its much 

 longer ovipositor and more obscure coloration, &c, and is regarded 

 by Thomson as a good species, but the contrary opinion is held by 

 Mayr. Allotria pleuralis, Cam., a new species of parasitic 

 Cynipidae taken in several localities in the west of Scotland. 

 Antaeon lateralis, Thorns., from Dumfries, a species of Oxyura new 

 to our Fauna. Nematus ochropus, Thorns., a saw-fly hitherto un- 

 recorded as British, but taken so long ago as 1825 by the late Mr. 

 J. C. Dale of Glanvilles' Wooton, in the south of England. There 

 is a ticket attached to the specimen to the effect that it was bred 

 from a " striped larva in willow." Poecilosoma longicome, Thorns., 

 likewise an addition, from various Scotch localities. There was 

 shown along with it an apparently undescribed Poecilosoma from 

 Rannoch. There were also exhibited two specimens of the fish 

 parasite Argulus foliaceus, which emerged alive out of a water- 

 pipe in a house in Apsley Place, having travelled all the way from 

 Gorbals Water-works. The species does not appear to be very 

 common in the district; but it has been taken by Mr. David 

 Robertson in the Paisley Canal. Daplmea pidex and Cyclops 

 quadricornis are occasionally found in our water-pipes, but neither 

 these nor the Argulus can be regarded as injurious, nor as in- 

 dicating impure water.
