The anterior portion of the body is broad, with the abdomen 
abruptly acuminate, terminating in two broad caudal Icbes. ‘The 
striae on dorsum are few in number and broad. The thoracic shield 
is short, broad and triangular, with lateral angles often gently 
rounded and the anterior portion pointed and projecting over the 
head. On the median area of shield there are three nearly parallel 
lines which extend to almost the anterior and posterior margins. 
Laterad of these there are a number of short irregular linear mark- 
ings. The dorsal setae are fine and short. 
The legs are of medium size with tarsi much narrower than the 
other segments. ‘The distal tarsal segment is shorter than the next 
tarsal segment. The feathered hair is small and has four rays. 
The tarsal claw is slightly knobbed and as is usual is longer than 
the feathered hair. 
The abdomen is shert and tapering, with a longitudinal furrow 
on either side of the median area or dorsum which is carinate. ‘The 
striae on dorsum are about forty in number and are broad and 
punctured. The lateral setae are fine and of moderate length. The 
first pair of ventral setae are similar in form but are longer. ‘The 
second pair of ventral setae are shorter than the first pair. The third 
pair of ventral setae are prominent, appearing to be a trifle stouter 
but somewhat shorter than the first pair. The caudal lobes are 
large, being short but broad. The caudal setae are of medium 
length and rather fine. The accessory caudal setae are apparently 
wanting. The epigynium is of medium size, with one pair of 
genital setae which are short and fine. Dr. Nalepa gives the length 
of the female as 150 microns and of the male, 130 microns. Of the 
many specimens which have been examined there has been much 
variation in the sizes of the mites which is perhaps determined by 
the differences in the ages of the individuals and the methods of
