This is the only apterous male that I have met with ; the contracted meta- 

 thorax and imperfect soutellum shew that the wings have not been lost by accident. 

 The antennas, which are neither verticillate-pUose, nor irregularly bristly, afford 

 the only character which forbids the insect to be placed with Dia/pria, as limited 

 by Forster. In Mr. Walker's collection.

Re-occwrrence of 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, C. Doaius, A. Aglaia, and 8. al^pinalis were 

 common ; but, with the exception of an occasional Carahus glahratus, or Pterostichus 

 wthiops, beetles were at a premium. The various lochs in the neighbourhood were 

 searched for Hydradephaga with hardly any result. The reason was soon dis- 

 covered. The lochs were 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. Prom 

 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 oare. 



The last evening of my stay in the island arrived, 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 diflBculty of getting in. Soon a newt appeared, 

 wriggling along. Hope rose rapidly ; for, from former experience, newts and D. 

 lojpponicus 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 safoly 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 very few exceptions, all were males. Along with the 

 Dytisci were also taken Agabus arcticus (common) and A. congener (sparingly). —
