 I'lii.s niyriupod seems to hnve a ])r(>fereiK'e for garden vegetables, 

 and especially for tubers and roots. It has l)een reported by Lintiun- 

 as feeding on kernels of ripening corn at Madison, Wiseonsiii. We 

 have not taken it in Jllinois. 



Pakajumis venustus Wood. 



This is one of oui- conunonest species (Fig. 285). We have found it 

 ill fall inside the husks and on ears of corn, burrowing in raspberry 

 and curi-aiit stems in May, and about clover roots in September. Most 

 of our specimens were collected in April and 

 .May; the remainder from September to 

 December. It is a species of northern range, 

 not known to occur south of Kentucky, 

 while the closely related I', inipressus is 

 southern, and i'ar(> in this latitude. Tiu^

 of corn and other grain.

This sjx'cies is common in Illinois and has been taken eating 

 corn grains in the ear, both on the ground and on the stalk. We have 

 found it under the husks between i\\v. rows of kernels.

'J\i7^anyclnis. 



Injiu'ies by the tiny pale mites (Fig. 230, 2.37) commonly called the 

 red spider are most serious on greenhouse plants and trees and shrubbery 

 of \arious kinds, especially in unusu.nlly liot and dry wc^ather. The 

 leaves and stems of infested plants are coated with a very delicate, almost 

 invisible web, and the under surface is (lii'ti(Ml with numerous fine dai'k 

 particles, which, undcM- a lens, are seen to be empty egg-shells and excreta. 

 The mites themselves are easily seen moving about over the smface of 

 the leaf. In hot dry weather almost any herbacef)us plant is liable 

 to infestation, but rar(>ly to serious injury. On two occasions in fall 

 we have found them at work on corn in Illinois. The same injury has 

 been noted on sugar-beets, and a full treatment of th(> species from
