(dr. a. C. OtTDEMANs) A SARCOPTEE OF A BAT. 273 



leg (I purposely don't say the last joint) bears at least five claws, 

 of which three larger and two shorter; two of the three large ones 

 are hyalin , whilst the other three claws are brown , chitinized. 

 The right leg of the second pair (to the left of our figure), shows 

 still a blunt ended short hair, characteristic in Psoricae, so we 

 must conclude that this hair is present on all the four fore legs , 

 at least on those of the second pair. The chitinized ring of the first 

 joint of ail the four forelegs shows a short hair directed forewards , 

 as the bases of the palpae also have, The first joint of the (im- 

 movable?) palpae also shows such a hair. The rigth mandible is 

 projecting out from the mouth; this mandible has the common form. 

 Fig. 12 and 13. Each third leg shows five (or six?) claws, but 

 apparently (see fig. 13) two claws are inserted on the last joint 

 whilst the other three claws belong to the second , third and fourth 

 joint. A short blunt ending hair, as in the legs of the second 

 .pair , is implanted on the third (or fourth) joint. The hair before 

 the third leg is a true hair, that between the third and the fourth 

 leg is lanceolated (see fig. 12). 



Fig., 14. The fourth leg has only two claws on its last joint, 

 which moreover bears a long flexible hair , as long as the leg itself 

 with its epimeron. 



Fig. 15 and 16. The eggs are ellipsoid ical with two different 

 axes. In many of them larvae m situ, are distinct, with the hair 

 of the third legs crossed on the ventral surface. 



Fig. 17. The larva has a nearly quadrangular form. The an- 

 terior margin is , however , rounded , and the animals being 

 invariably well fed, does show several lobes on this margin, as well 

 as on the posterior one. The skin is wrinkled as in other Psoricae, 

 The direction of these minute wrinkles is better shown in my 

 figure than described. In general the wrinkles run parallel to the 

 margins, but on the very dorsal surface they run transversally. 

 The anus is situated on the last fourth part of the notogaster. 

 Two flexible hairs are situated between the first and second fourth 

 part of the notogaster; two blunt bar-shaped hairs near the margin 

 - between the fore and hind half of the notogaster, and six smaller
