long (c. 25 microns) and fine; the inner setae are very short. 
The sternal ridge reaches to the region of the inner corner 
of the epimeron and is not forked. The first pair of thoracic 
setae are short (c. 8 microns) , the second are anterior to the 
plane of the posterior end of the sternal ridge and about 30 
microns in length, the third pair are the longest (c. 45 
microns) . The abdominal rings, about 80 in number, have a 
distinct row of small, well separated tubercles along their 
posterior border but in the last five these are replaced by 
ventral longitudinal striations. The epigynum is about 20 
microns in width and lies immediately posterior to the 
cephalothoracic region ; the lower flap is hemispherical and 
slightly keeled; the upper is smooth and either flat or 
slightly arched. The genital setae are lateral and about 12 
microns in length. The lateral setae are below the plane of 
the epigynum, are fine, and are about 20 microns in length. 
The first pair of ventral setae are the longest, about 60 
microns, the second are the most median in arrangement 
and about 50 microns in length, the third are the coarsest 
and shortest (c. 20 microns) . The short, broad telson bears 
the long caudal setae (c. 90 microns) and the very minute 
accessory setae (c. 4 microns) . 
Eriophyes eucricotes multistriatus var. n. 
Host : Lycium halimifolium Mill. 
The typical form of this species was described by Nalepa 
in 1892 from specimens collected from pustules of the leaves 
of Lycium europseum L. and Lycium mediterraneum Dun. 
occurring in southern Europe and Algiers. The mite from 
Lycium halimifolium produces a gall very similar to that 
of the typical species, namely, a pustule on the leaf, but in 
addition attacks the young twigs, petioles, floral leaves, 
stamens, and ovaries of the host. Besides its apparent limi- 
tation to a different host there are constant morphological 
characters that distinguish multistriatus from the typical 
form: the abdominal striae are uniformly greater in num- 
ber, the tuberculation of the abdominal rings is both dorsal 
and ventral in distribution, is finer and more abundant, and
