226 RED SPIDER. 



legs testaceous, with darker thighs ; antennaB also testaceous, 

 and lowest joint darker. The larvae, when full-grown, were 

 about the eighth of an inch or rather less in length, and 

 remarkably active in their movements. The colour to the 

 naked eye, smoky grey, when magnified, of a smoky yellow 

 with black markings ; the head with some small black marks ; 

 the three succeeding segments each marked with two black 

 patches, the rest of the body marked lengthwise with six 

 rows of black tubercular spots with bristles. With a higher 

 power, the patches and spots are found to be formed of 

 aggregations of little black dots, each collection bearing two 

 or three or more white hairs, with here and there a few 

 black hairs also. 



On jjlacing the maggots on some Plum leaves infested with 

 " Eed Spider," I found them shortly after busily feeding, and, 

 failing other food, the maggots preyed on each other. The 

 pupal change was gone through in the usual method, of the 

 Ladybirds — the larva suspending itself by the tip of the tail 

 to a leaf. The pupa was of a shining black, and the change 

 only occupied a few days. 



A plentiful supply of specimens were sent me during August, 

 1893, by Mr. Edw. Goodwin, of Canon Court, near Maidstone, 

 of which detailed notes are given in my ' Annual Eeport ' for 

 that year. 



Note. — In the preceding pages I have only entered on the considerations of 

 Tctranyclnis telarius as a general leafage pest. But it may not be out of place 

 to mention that in the ' Praktische Insektenkunde ' of Dr. E. L. Taschenberg 

 this species is noted in his list of infestations of the Hop (pt. v. p. 224) ; and 

 at p. 153 preceding, the species is noted as Tetr-anychus [Acarus) telarius, L. 



Also in vol. i. of 'Insect Life,' p. 72, Prof. Riley remarks that he had been 

 struck in his observations during the Hop harvest in Kent, in 1887, with the 

 similarity in the general aspect of things both on the Hop and Plum in England 

 and in America. . . . " and everywhere the omnipresent Red Spider 

 {Tetranyclius talarius)." 



1 have not myself had the opportunity of comparing it with authorized 

 descriptions, but it is of interest to have the definite statements of the above 

 well-known entomologists that respectively in England and America and in 

 Germany they consider the "Red Spider " of the Hop to be 2'. telarius.
