chanter of the four anterior legs with a lamellate hair placed dorsally ; the tarsi with 

 several terminal appendages including a pair of closely appressed claws, a very long 

 bristle, and the four capitate hairs, so frequently seen in Tetranychus. 



Length, 0.235 mm.; width (hind margin of cephalothorax), 0.149 mm. 



Male. — The male is decidedly smaller than the female, and the abdomen is sud- 

 denly constricted behind the cephalothorax and decidedly more attenuate than is 

 the case with the female. The legs of the male are relatively longer, colorless, and 

 the hairs and bristles are more conspicuous. 



Life-History 

 The Egg. — The egg is thickly elhptical in Hnear outhnes, and 

 measures .096 mm. by .067 mm. It is blood red in color from the 

 first. The eggs are usually deposited with the long axis perpendicular 

 to the leaf. An effort is made by the female to deposit the eggs in a 

 depression or abrasion of some kind. These failing, she deposits 

 them in old molted skins (see fig. 38c) or in the groove by the side of 

 the mid vein. When oviposition is taking place freely the eggs often 

 become closely packed (like those of Coccinellids), often comprising 

 clusters of several hundred. It appears from our limited breeding 

 experiments that the female deposits usually about twenty eggs.
