There are five groups of spinnerets: the anterior group 

 includes from 1 to 3, usually, 1 or 2 ; the anterior 

 laterals, from 3 to 7, and the posterior laterals, from 3 

 to 5. The number of spinnerets is variable, and in many 

 instances they are very scattering. There are two pairs 

 of lobes : the median pair prominent, about as wide as 

 long, and usually notched on the lateral margin; the 

 second pair about half the size of the first, rounded or 

 more or less pointed. Plates inconspicuous or absent, 

 spines prominent, situated as shown in the illustration, 

 the second about as far from the first as the third is 

 from the second, the fourth about twice as far from 

 the third as the third is from the second. Rather deep 

 incision between first and second lobes. Club-shaped 

 organs, about which the spinnerets are grouped, arranged 

 as shown in the illustration. Anal opening about as far 

 from the incision as the spines are long. 



This species occurs on wild and cultivated cheri-y, 

 apple, pear, plum, quince, currant, and possibly on
