438 VARIETIES. 



mesothorax very long, dark brown, with two longitudinal 

 white lines, and a dash of white at the base of each wing : 

 body nearly black, with six delicate rings, of a pinkish yellow 

 colour : fore-wings brown, with two oblique, transverse, white 

 lines nearly parallel with the exterior margin, and within these 

 are irregular white markings on the disk ; hind-wings white, 

 with two broad bands, and the nervures brown : legs black, 

 the tarsi annulated with white. The female apterous, with 

 seven rings on the body. The size is, as nearly as may be, 

 that of N. his-pidaria. I shall be glad to show the specimens 

 to any entomologist who may wish to see them.

40. Capture of Georyssus pygmceus. — Sir, When engaged 

 in collecting fossils in the cliffs, at Walton-on-the-Naze, Essex, 

 about a month since, I came upon a spot where numerous plants 

 of Tussilago furfara and Epilobium hirsutum indicated the 

 presence of water filtering through the cliff. A large mass of 

 half indurated clay attracted my attention, from having many 

 minute particles of clay or mud apparently animated, and slowly 

 moving upon its surface. With some trouble I succeeded in 

 picking up and bottling two of these, and, on subsequent ex- 

 amination, proved them to be specimens of Georyssus pyg- 

 mceus, bearing masses of clay larger than themselves, and thus 

 entirely concealed. I regret not getting more, as I believe it 

 is by no means a common insect. 



If this notice is worth putting in a corner of your Magazine, 

 it may draw the attention of entomologists to this insect in 

 similar situations.

41. Wilsons Entomologia Ediniensis. — Sir, A moment's 

 reflection will, I think, convince you that what has been said 

 of this work, at p. 222, is not quite in unison with the usual 

 candour of your Magazine. It is perfectly true that it con- 

 tains a great number of the " commonest London insects;" 

 but is this any fault of the author's? or does this fact, in the 

 slightest degree, diminish the value of the work as a local 



fauna? Assuredly not. If the work professed to give an 

 account of those insects only which were peculiar to the
