same genus (King, 1869) ; and the following species of Cotes — distincta, dorsata, 

 optima, proxima, punctata, and riifa, Broun [Man. New Zeal. Col., pp. 1165 — 1167 

 (1893)]. It is to be regretted that M. Pic, who has lately paid a good deal of 

 attention to this interesting Family of Coleoptera, has considered it necessary to 

 describe so many new species in obscure ephemeral unobtainable publications,* and 

 that he has not been able to find better specific names than sutura-depressa,fortiter- 

 punctatiis, pygidiolongus, scutelloniger, &c. I would also here enter my protest 

 against the wholesale naming of trivial varieties (upwards of twenty varietal names 

 having been proposed by M. Pic in Anthicus alone), the study of these insects not 

 being facilitated by a trinomial system of nomenclature. The list contains a large 

 number of typographical errors, and references to all published figures are omitted. 

 The number of species of AnthicidcB enumerated in the Munich Catalogue is 424, 

 the additional 414 of M. Pic's list making a total of 838 species. — Q. C. Champion,

Aleurodes ruhicola, Doug. — Yesterday I visited the restricted locality on 

 Blackheath adjacent which is affected by these insects, and about the bases of the 

 bare stems of the blackberry bushes saw a multitude of their larvae (or now perhaps 

 become pupae) tightly adherent to the under-side of the fallen leaves. These had 

 been hustled about during the winter, some turned upside down, some very wet, 

 others very dry and broken, but the Aleurodes maintained their hold. Against the 

 dark background of the leaves their pale yellow colour rendered them very con- 

 spicuous, yet they had no enemies, for neither birds, mice, parasites, nor other 

 creatures had molested them. Nature had protected them, and unharmed thev 

 await the advent of June, then to expand their white, spotless, moth-like wings for 

 the brief culminating stage of their existence. — J. W. Douglas, 153, Lewisham

Coccids associated with ants. — With reference to Mr. W. W. Smith's articles on 

 this subject (Vol. iii, 2nd series, pp. 60, 307) it may be of interest to state that at the 

 end of May last year I found Pseudococcus aceris among ants {Lasiiis fuliginosus). 

 At that time I had collected on lime trees, eggs of the Pseudococcus which had been 

 laid in waxen secretion (and afterwards became larvse) and females nearly all 

 infested with parasitic Hymenoptera. The greater, therefore, was my surprise when 

 I afterwards found on detached pieces of bark in the ants' runs three large healthy 

 ? of the above-mentioned species, well filled with eggs, but they had no waxen 

 threads attached to them ; they were surrounded and caressed by the ants. Had 

 they been dragged in by the ants, or had they strayed into the runs and there met 

 with friendly treatment ? Yet it is certain that their residence there was not un- 

 favourable to them, and that they had met with no small enemies, — Kaeei Sulc

Why are large Perlidce resident in Scotch but not in Swiss lakes ? — At p. 63 of 

 the present volume Mr. K. J. Morton remarks that some of the larger PerlidcB, 

 which in Switzerland live almost exclusively in running water, inhabit stony shores 

 of lakes in Scotland. May not this be accounted for by a difference in the average 

 maximum summer temperature of lake-shore waters in the two countries, in neigh- 



* A large number of names quoted by M. Pic as published in 1892 are not to be found in the 

 Zoological Keoord for that year !
