AN ALLEGED PARASITIC TYROGLYPHID. 
BY NATHAN BANKS. 
Tyroglyphids have been found in many situations where one 
would never expect them, nor easily explain their presence. 
They have a minute migratory stage which may be attached to 
various insects, and in this way they may be transported far 
from their birthplace. It was one of these mites that an Eng- 
FIG. 6 Carpoglyphus alienusi 9 . 
lishman thought he had produced by means of electricity. 
Not the least remarkable of the many strange habitats, is that 
in the following case : 
Early in 1904 Dr. J. de Haan, Director of the Geneeskundig 
Laboratorium te Weltevreden of Batavia, Java, sent to me for 
determination some mites found in the urine of a patient 
affected with a kidney disease. Every time he passed urine 
some of these acarians were found surrounded in pussy matter.
