it is Deal, but not more than four, or at the most five, species have yet occurred there. 

 Of these seven species, examples of four (G. marinus, G-yll., O. natator, Linn., G. 

 elongatus, Aube, and G. minidus, Fabr.), were occasionally obtained from one dip of the 

 water net, these all being of gregarious habits, and clustering together in hundreds, 

 indiscriminately, on the open water; the other three, (?. colymbus, Er., G. bicolor,'P&y'k., 

 and G. Suffriani, Scriba, frequented the shelter of the reeds along the margins of the 

 broads and ditches, and were ruuch less sociable. G. marinus : by far the most 

 abundant species, and in point of numbers probably equalling all the other 

 Gyrini together. G. natator (including examples apparently intermediate between 

 the typical form and the var. mergus, Ahr.) : common. G. elongatus : common, 

 on the open water and in sheltered places. G. minutus and G. Suffriani : freely in 

 some places ; the former not hitherto seen alive by me so far south, the latter also 

 met with at Ranworth and Honing (not Horning). G. colymbus: of this rare 

 species I managed to secure about thirty specimens ; it may be easily separated from 

 the allied forms by the distinctly and very neatly punctured interstices of the elytra, 

 but the punctuation is so minute as to be only visible under a very powerful lens ; 

 in dull abnormal examples the punctures are not easily seen. G. bicolor : apparently 

 the least common of the Norfolk Gyrini; about twenty examples occurred; this 

 species comes very close to G. elongatus, but the more rounded outer apical angle of 

 the elytra seems to be a constant character, notwithstanding the great variation in 

 sliape in both sexes of the two insects. Dull forms of most of these species oc- 

 curi-ed : also examples of G. colymbus and G. elongatus with the apices of the elytra 

 testaceous or rufous (very conspicuous when the insects were alive). The Gyrini 

 above noted do not include G. opacus, Sahib. ; Mr. Edwards, however, informs me 

 that he has taken it abundantly in more inland localities. — Id. : October 2nd, 1890. 



Anisotoma Triepkel, Sfc, at Aviemore. — While staying at Loch Alvie by 

 Aviemore during the early part of August, I was fortunate enough to capture a male 

 example of Anisotoma Triepkei, Schmidt, by sweeping in a grassy place on a fine 

 warm evening. I also found a specimen of Megacronus inclinans, Er., by turning over 

 stones at the edge of a small mountain stream. Owing to the rainy weather and 

 the time of the year I was unable to obtain many beetles. The present summer 

 appears to have been the wettest experienced in the district for the last twenty years, 

 besides which, very little wood had been cut in the forest for a long time. For the 

 names of the above beetles I am indebted to Mr. Champion, who informs me that 

 neither of the species mentioned was met with by him at Aviemore. — R. W. Llq-ed,

Anosia Plexippus {Danais Archippus) at Eastbourne. — It may be worthy of 

 record that at about 2 o'clock in the afternoon of the 2nd inst., a large specimen 

 of Danais Archippus was flying for some time up and down the Marine Parade at 

 Eastbourne. It seemingly wished to settle on the road, but was hindered by passing 

 vehicles, and eventually went out to sea and was lost to sight. So many foreign 

 steamers pass close to land at Beachy Head that its appearance is not difficult to 

 account for.— A. H. Clarke, 109, Warwick Road, London, S.W. : October, 1890.
