I have several plumes and Phycidice, which are as yet unnamed ; and had not 

 the season of 1886 been very backward indeed, and with an unusual amount of snow, 

 the probabilities are that our list would have been considerably extended.

NOTES ON SOME BEITISH AND EXOTIC COCCIDM (No. 19). 

 BY J. W. DOUGLAS, T.E.S. 



Plate I. 



Lecanium saeotiiamni, n. sp. 



? scale, adult ; oval, very convex, chestnut-brown, shining, smooth, on the sides 

 only and extending to the margin 8 — 9 short, transverse black lines, very slightly 

 raised and not very perceptible (sometimes wanting entirely), amongst which are 

 slight confluent punctures, sometimes also a few punctures on the disc. Eventually, 

 ■when the scale becomes quite dry and empty, all the punctures become deeper, es- 

 pecially on each side of the smooth median line, which thus is sometimes rendered 

 slightly but obtusely carinate. Anal cleft short, the point above it very small, not 

 projecting. Antennae (fig. 2a) very small, of 7 joints ; 1st and 2nd widest, in 

 length subequal ; 3rd longest, nearly as long as the remaining four together, with 

 two long hairs near the apex ; 4th, 5th and 6th each successively shorter and 

 narrower, the 5th with one very short hair ; 7th very small, with several long hairs. 

 Legs (fig. 2b) long, slender ; tibiae scarcely wider than the tarsi, but a trifle longer ; 

 tarsi with two long digitules very finely clubbed; claw short, obtusely pointed, with 

 two short, dilated digitules. There are two hairs on the trochanter, and three on 

 the femur, but none evident on the tibiae and tarsi of the three specimens examined, 

 thought it is possible they may have been rubbed off in the preparation for the 

 microscope. Length, 4 — 5, breadth, 4, heiglit, 3 mm. 



Larvae very small, pale yellowish, present no tangible features to distinguish 

 them from those of other Lecania. 



I am indebted to Mr. E.. Newstead, Grosvenor Museum, Chester, 

 for the great paius he has taken in preparing specimens and making 

 drawings of the atitennae and legs. 



In September, 1889, Dr. T. A. Chapman, Hereford, sent some 

 scales which he had just then found on stems of broom {Snrofhnmnus 

 scoparius) . In some respects these seemed to be like Lecnnmm genistce.

 pine forests on the coasts at Hyeres and Cannes, on Gcnida anglica ;
