CcBcilius atricornis, McL., in Arundel Park. — I was fortunate enough to take 

 five" specimens of Ccecilins atricornis, McL., by beating laurel, hawthorn, &c. ; no 

 doubt many more might have been taken had time permitted, as the Psocid was not 

 confined to a limited area, but occurred at various points around the lake. I do not 

 think that C. atricornis has been taken by beating before, the previous records men- 

 tioning that the specimens were obtained among rubbish in dry ditches. — J. J. F. X.

Quedius longicornis, Kr. — A short while ago I found among my Quedii a 

 specimen of this very rare species. I captured it under the trunk of a tree lying on 

 the ground in Bretby Wood, near Burton-on-Trent, while searching for Boletohins 

 inclinans, which occurred very sparingly in the same locality. Mr. Blatch has taken 

 the species in Buddon Wood, Leicestershire, but I know of no other record from 

 England. It has been taken very rarely in the Solway District of Scotland by 

 Dr. Sharp. — W. W. Fowler, Lincoln : January IQth, 1888. 



The ISntomology of Gibraltar. — I am still working fairly hard at the entomology 

 of this most interesting'locality, with, on the whole, very good success, at any rate 

 in Coleoptera, in which I have increased my local list to nearly 1100 species. We 

 had a great deal of rain just after Christmas (12 inches in 7 days !), so there was a 

 vast accumulation of flood refuse about the streams, most productive in beetles ; 

 indeed now, after a fortnight's fine weather, it still repays examination. Perhaps 

 my most interesting capture has been the little ants' nest " Hister," lately described 

 by Mr. Lewis {ante p. 16-1) as HetcBrius acutangulus, of which I have lately found 

 two examples in this neighbourhood. I went for a short walk on the lower slopes 

 of the Rock this afternoon, and saw ten species of butterflies on the wing. Colias 

 Edusa was plentiful, and some of the specimens wei-e so newly emerged that they 

 could scarcely fly. Euchloc Belemia is out, but this I saw more than a month ago 

 at Tangier. I have been devoting a little attention to the ants lately, at Mr. Saun- 

 ders' suggestion. — J. J. Walker, K.M.S. " Grappler," Gibraltar: Jan. 2*tth, 1888. 



Dicerca prolongata, Le Conte. — Early in December, while I was ciiopping up 

 r an aspen tree {Populus tremulo'ides, Michx.) here, I came across the remains of a 

 beetle, belonging to the Btrprestida, in the burrows of some larvae which had evi- 

 dently destroyed the life of the tree. I sent this to the Agricultural Department 

 at Washington, and am informed that the species is Dicerca prolongata, a beetle 

 previously recorded for Colorado by Packard (Bull. 7, TJ. S. Ent. Com.), but supposed 

 by him to be a pine feeder, though, he adds, his specimen was found on a poplar 

 tree. Not long after, I found one of the burrows in another P. tremulo'ides tree 

 tenanted by a Coleopterous larva, which I have no doubt is that of D. prolongata, 

 from its great resemblance to the figure of the larva of Dicerca divaricata, Say, as 

 figured in 3rd Kept. U. S. Ent. Com., pi. vi, fig. 2. D. divaricata has long been 

 known as injurious to chcri-y and peach trees, and it is therefore interesting to find 

 a species in Colorado destroying the poplar. In places where the trees were valued 

 it might be considered a decidedly injurious insect, but I find it rather beneficial 

 than otherwise myself, since the dead trees sujjply me with firewood, a thing not to
