the elm, sajs vaguely " Celui-ci vieiit sui* les arbres." He was the first to name 

 Reaumur's species as Chermes arbornm linearis. Modeer {I. c.) cites Reaumur and 

 Geo£froy, dropping " arborum," and giving the name as " linearis" only (so that he 

 vras not correctly cited by Gmelin), and he says the insect "lives on the branches 

 of elm trees." It thus appears that the prior name of the elm feeder is linearis, 

 and it should not have been supplanted by Gmelin's conchiformis ; thus also Signo- 

 ret's linearis {nee Geoffr., Modeer, as he has it) requires another name. At any 

 rate, Goethe's conchifortiiis is not the conchiformis of Gmelin. I find the true 

 Mytilaspis linearis, Geoffr., Modeer, rarely on elms ; I believe it is now first intro- 

 duced as British, and that the conchiformis of Curtis and Walker is only MytiJaspis 

 pomorum, Bouche, Signoret. Briefly the synonymy is : — Gallinsecte de coquille, 

 Reaum. Chermes arborum linearis, Geoffr. ; Coccus linearis, Modeer ; Coccus 

 conchiformis, Gmel. ; Mt/tilaspis conchiformis, Sign. 



Mytilaspis vitis, Goethe, sp. n. 



This form Dr. Goethe finds on vines, and it is not impossible that it may occur 

 in Britain. The formula of the spinnerets is given as 9^11 anterior, 14—16 ant. 

 lat., 10 — 12 post, lat., and the species is i-egarded as quite distinct from M. pomorum, 

 which it resembles otherwise. The scales of the ? are found on the two-years'-old 

 wood. The larvse are attached to the young shoots, especially near the buds, where 

 they are very perceptible, as the place where the rostrum is inserted becomes brown 

 or blackish. With the discoloration a swelling is associated, so that the young 

 creature sits on a small eminence. 



Lecanium pyri, Schrank. 



Dr. Goethe says he finds this not only as usual on apple and pear trees, but 

 also on whitethorn ; by the latter I apprehend he means L. genevense, Targ.-Tozz., 

 which he does not mention by name. 



Lecaniuni cerasi, Goetlie, sp. n. 



Dr. Goethe finds, principally on cherry trees, but also on plum trees, in the 

 spring, female scales of a Leeanium which he says do not agree with any described 

 by Signoret. They are 4 nnn. long, 3 mm. broad, and 2i mm. high, colour reddish- 

 yellow, shining ; the male, which appears in May, has white wings with a dark red 

 spot between the margin and the nerve, body red-brown. I also find such scales 

 here on the cherry trees, but have not been able to distinguish them from L. pyri, 

 Schrank, nor do the scales or imago of the male afford any distinctive characters. 

 As to the remark about the descriptions by Signoret it must be noticed that he only 

 refers to the adult scales, the yellow colour mentioned by Goethe becomes brown in 

 a short time, as in other reputed species of this group. 



I also find similar scales on laurel {Primus laurocerasus) ; I notice on the grey 

 scales of the male that the oval coronet on the back shows distinctly white, as Sig- 

 noret represents as existing in L. prunastri, hwt the imago differs not from L.pyri. 



Leeanium variegatum, Goethe, sp. n. 



This, it is stated, is found somewhat abundant on plum trees and apple trees, 

 singly on the latter. The specific name is adopted, because the $ scales show a re- 

 markable variegated coloration up to the time of oviposition. At first yellow-browil
