372 ARACHNOIDEA. 



CASE described on the maple and horse chestnut. They consist of 

 long pointed hairs, which agree with the normal hairs of the 

 bearded angles of the leaf nerves in appearance and colour. 

 Upon the upper side of the leaf a scarcely perceptible raising of 

 the lamina shows the presence of such hair tufts. Dr. Low 

 found Phytopti in these. 



Legnon circumscriptum, Bremi. 

 A very narrow rolling of the edge of the leaf on the upper side^ 

 almost all the way round. It begins in May, when the leaves of 

 the beech are still tender and long, and deeply notched at the 

 edge. Through the rolling up of the edges, the notches are rolled 

 in with it, and these are the only vegetable contents of the roily 

 which soon appears thickened and cartilaginous. 



On the Scotch Fir. 

 Phytoptus Sp. 

 These are bark galls described by Von Hartig ("ForstL. 

 Conversat," Lex. II., Aufl. 1836, p. 737), which are filled with 

 exceedingly numerous gall mites. They are dirty white, almost 

 equally thick and cylindrical, f millimetre long, having a remark- 

 ably long snout, out of which they can stretch the piercing 

 apparatus far. 



On Clover and other Papilionaceous Plants. 



VOLVELLA CORONILL^, A7n, 



The larvae of these mites live between the close clapped pinnae,, 

 and by these means, the little misformed leaves get a pod-like 

 appearance. Kaltenbach states that he has noticed similar de- 

 formations, in consequence of the sucking mites, in Vicia sepium, 

 and Trifolium repens.
