feeder, but particularly attached to PnpilionacecB, and in some years 

 very destructive to peas and other farm crops. I apprehend that the 

 Lecania also helped to pump out the life of the broom. 



The female Lecania, as a rule, fix themselves in early life, and 

 remain attached to the same site for the remainder of their existence. 

 " J'y suis, j'y reste," might be their family motto. But Dr. Chapman 

 tells me that these on the broom were still on the move in May, the 

 probable reason being, I think, that they found the supply of sap on 

 which they depended for a living was getting short, or it may be de- 

 teriorated in consequence of the additional absorption of it by tteir 

 fellow-squatters, the Aphids, and so they felt compelled to shift to 

 "fresh wood and pasture new," a proceeding they would not otherwise 

 have adopted. I once witnessed a similar migration of young, full- 

 sized females of Lecanium heaumontioB, which moved about freely on 

 the withering stems of Beaumontia grandiflora, on which they had 

 come to me (of. Ent. Mo. Mag., vol. xxiv, p. 95). 



Lecanium ciliatum, n sp. 



9 scale, mature. Ochreous to light brown ; outline variable, broad rounded 

 oval (fig. 3a profile, fig. 3b front view), or at times irregular narrow oval, or trans- 

 versely oval, broadly I'ounded at the sides, being then broader than long (length, 5, 

 breadth, 6 mm.) ; in all cases the middle portion is occupied by a high, broad, 

 smooth, fusiform swelling, of which one point is close above the small anal cleft, the 

 other not extending to the anterior margin by a considerable space ; the top with 

 two distinct rows of deep, more or less large, punctures ; the entire elevation re- 

 sembling a convex, pointed scale, superimposed on a broader, flatter one ; the re- 

 mainder of the surface of the scale being comparatively flat, and covered with a 

 reticulation of confused lines and confluent punctures ; the entire margin with a 

 fringe of fine concolorous hairs (Mr. Newstead says these are white and conspicuous 

 to the naked eye in the living insect), which become more or less abrated in the dry 

 scale. Antennae (fig. 3c) of 7 joints ; Ist stout, widest ; 2nd not quite so long ; 3rd 

 as long as the 4th, 5th and 6th together, without hairs, these three latter in 

 length subequal, the 4th a trifle the longest, the sides suddenly constricted in the 

 middle, where there are one very long and one very short hair placed together on 

 one side, and a still shorter one on the opposite side ; a single long hair on the 1st, 

 2nd and 5th joints, two on the 6th, and about six on the 7th. 



" Tibiae about twice the length of the tarsi, constricted at about one-third of the 

 distance from the apex. Tarsal digitulcs long, more than two-thirds the length of 

 the tarsi" — (E,. Newstead). Length, 5'5, breadth, 5 mm. 



" (? scale (fig. 3d), glossy white, elongated, convex, with one centra! and two 

 lateral square, granular projections, some of the posterior ones double ; margin with 

 a rather strong, glassy fringe. The only specimen I possess has the posterior portion 

 wanting, the imago having escaped before I discovered it." — (R. N.). 



" Larvae large, dark yellow ; antennae of 6 joints ; Ist widest, oval, in length
