large numbers, and larvse swarmed and subsequently hatched oiit in hundreds 

 from the refuse of these nests. Q. 2iuncticollis, Th., was also bred from larva 

 taken from several nests, bixt as yet I have been unable to bx'eed either of the 

 Oxypodas, though H. ravilla, Er., emerged in numbers. The remaining species 

 found arc no doubt only casual inhabitants of these nests. 



I lisually locate the wasps' nests near hei'e while the wasps are still strong 

 on the wing, jotting down details as to precise locality so as to be able to find 

 them when there are no wasps flying to guide one to the entrance, and then 

 await the time when the early frosts kill off all the wox-kers, and find the nests 

 most productive of good species within about ten days after the wasps have 

 finally left them. — H. Britten, Prospect House, Salkeld Dykes, Penrith :

Cassida nohilis, L., in Dumbartonshire. — There being, so far as I am aware, 

 no record of Cassida nobilis from Scotland, it may be of interest to readers of 

 this Magazine to know that on June 27th last I took five specimens among 

 stones under Silene maritima, on the shoi'e cf Loch Long, near Peaton, Dum- 

 bartonshire. The presence of numerous Cassida larvaj on the plants first 

 attracted my attention and led to the discovery of the beetles. Dr. D. Sharp 

 has seen one of the specimens and confirmed the identification. — William 

 Evans, Morningside Park, Edinburgh: February 9th, 1911. 



Ova of Xanthia ocellaris taken in the field. — I have svicceeded this year in 

 finding four batches of ova of X. ocellaris, and as this is, I believe, the first 

 time that they have been taken in the field in England, the record may be of 

 interest. All the ova were laid between the catkin buds and the twig on black 

 poplar, and in three cases they were on the under-side, and therefore least 

 exposed to the sun. The niunbers were respectively 11, 7, 5, and 2. — H. O. 

 Mills, Hurst Cottage, Hamjjton-on-Thames : March 1st, 1911. 



^-^ Hymenoptera Aculeata in Cornwall in 1910. — The climatic conditions 

 throughovit the year wei-e extremely unfavourable for Entomology, embracing 

 as they did low temiDeratm-e, lack of sunshine, continued gales of wind, and an 

 abnormal rainfall. The scarcity of Lepidoptera was especially noticeable, though 

 not surprising, when one considers that similar conditions prevailed during the 

 season of 1909. With Hymenoptera, however, the results were more satisfactory, 

 and I have to record having captured 101 species of Aculeates, amongst which 

 are a few very rare ones. In my contribution to the February number (1909) 

 of this Magazine I had the pleasure of saying that all the species had been 

 determined by the late Mr. Edward Saunders, whose untimelj' death took place 

 in that very month ; may I therefore be permitted to express how deeply, in 

 common with all Hymenopterists, I deplore this great loss to the Entomological 

 world. His co-worker, the Rev. F. D. Morice, has generously come to my 

 aid and determined all my captures for 1910, and to him I tender grateful 

 thanks for this valuable assistance and encouragement. 



The following is my list, giving all the data possible, which information
