This is the only apterous male that I have met with ; the contracted meta- 
thorax and imperfect scutellum shew that the wings have not been lost by accident. 
The antennae, which are neither verticillate-pUose, nor irregularly bristly, afford 
the only character which forbids the insect to be placed with Diwpria, as limited 
by Forster. In Mr. Walker's collection.

Re-occwrrence oj Dytiscus Icupponicus in Mull. — During the month of July, 1866, 
I spent some days in the island of Mull. Recollections of fine " doings" there, some 
years ago, raised sanguine hopes ; but, on the present occasion, beetles seemed to 
have left the island. 
Such Lepidoptera as E. Blandina, 0. Downs, A. Aglaia, and 8. alpinalis were 
common ; but, with the exception of an occasional Carabus glabratus, or PterosticTius 
ctthiops, beetles were at a premium. The various lochs in the neighbourhood were 
searched for Hyd/radephaga with hardly any result. The reason was soon dis- 
covered. The lochs wore absolutely swarming with trout, so that beetles had no 
chance. Compelled, therefore, to lay aside the net, I consoled myself with the rod. 
Lot the Coleopterist note, that trout and beetles go in inverse proportions. From 
the top of one of the hills, looking down on the beautiful sound of Mull on the one 
side, and on Staifa and lona on the other, I counted some sixteen lochs and tarns, 
all of which I searched with care. 
The last evening of my stay in the island amved, and Dytiscus lapponicus, one 
of the chief objects sought, had not been seen. I felt disappointed. There was 
one small tarn which I had not visited, and in regard to which I felt uncomfortable. 
So, starting off late in the afternoon, through a drenching rain, over bog and stream, 
I reached the spot. It was gloomy enough. The loch lay in the bottom of what 
might once have been the crater of a volcano. No trout were visible : everything 
had a dead look. 
No stream apparently issued from the loch, so my hopes began to rise. Where 
no stream goes out, trout have a difficulty of getting in. Soon a newt appeared, 
wriggling along. Hope roso rapidly ; for, from former experience, newts and D. 
lapponicus I knew to be great friends (perhaps the newts would say enemies). 
Shortly after, a magnificent "Devil's coach," with graceful curve, hove in 
sight. All right now. He was secured, and the search began in earnest. A few 
minutes, the wished-for sight appeared. There he came, slowly paddling along, 
keeping close to the bottom ; the elytra of a strange pale green, with the yellowish 
streaks appearing very distinctly. In a few seconds he was safely landed and 
gloated over. Then came another, and another. My bottles were soon full. I was 
obliged to tie them up in a pocket handkerchief, and, finally, in a corner of the net. 
Darkness coming on, I was compelled to desist ; but in about an hour and a half I 
had the satisfaction of capturing some 45 specimens of D. lapponicus. It was some- 
what strange that, with veiy few exceptions, all were males. Along with the 
Dytisci were also taken Agabus arcticus (common) and A. congener (sparingly). —
