would go again and get some scales of the male, but in April when I 

 visited the place, I found to my disgust, that it had been appropriated 

 for building purposes, the water had been drained off, the trees were 

 dead, and there were no scales. It was not until June 9th that I 

 succeeded in finding some ? scales of the Lecanium on an alder tree 

 at Catford, and then it was too late to obtain male scales. 



There can be no doubt that this is the Lecanium alni of Modeer ; 

 the special mention of the absence of wool or farinosity shows clearly 

 that it cannot belong to the genus Oossyparia, as Signoret puts it 

 (Ess. Cochin., 319). Whether the species is the Coccus ulmi,JAnn.., 

 as I think is probable, is to be proved ; Lecanium alni, Modeer, is 

 given without any synonym by Walker in his list of British species. 

 Coccus alni, Schrank, Fauna Boica, 144, 159, may well be Modeer's 

 species, though it is not cited. De Geer does not notice the 

 Coccus alni of Modeer, but he remarks with reference to the scales 

 he found on willow (C. rotundus salicis, De Gr.), that he found some 

 quite similar to them on alder, and he considered them to be of the 

 same species (Mem., T. vi, p. 442). 



PULTINARIA CAMELLICOLA, Sign. 



On January 29th last Mr. Parfitt sent me from a greenhouse at 

 Exeter a leaf of camellia on the under-side of which were several 

 yellowish, extremely flat, oval scales, but two of them had a slightly 

 raised brownish line down the middle. They were so like the scales 

 of L. liesperidum that I deemed they were that species, which is found 

 on many different plants ; and having pinned down the leaf so as to 

 prevent its warping, I put them in a box on one side. Looking at the 

 leaf on February 23rd I saw that all the scales except two had dried 

 and become loose. Of the two one remained fixed, and underneath 

 was a developed male, dead and adherent to the scale ; the other scale 

 had disappeared, and in its place was a white, slightly convex, smooth, 

 shining scale, which, when I attempted to raise it with a needle, broke 

 and disclosed a male imago alive. The head, eyes, antennae, thorax, 

 legs, and abdomen were wholly yolk-yellow, the antennae thickly set 

 with short projecting hairs, the two anal filaments snow-white, the 

 broad wings smoke-white, sub-opaque, the costal area and also the 

 adjacent ordinary nerve faintly tinged with pink. 



The male of L. Jiesjjeridum, and indeed of all the species of that 

 group, being entirely unknown (excepting the very ambiguous L. 

 7ffMr«', Boisd.), I hesitated as to the name; since then I am con- 

 vinced that this is the male of Pitlvinaria camellicola, Sign., the
