and produced laterally so as to be almost dentate. Claw of jQrst 

 leg small ; the pulvillus present. Some of the hairs on the dorsal 

 surface of the legs are long. Hairs on ventral surface of legs 

 very few in number. First coxa apparently without any 

 posterior spur ; the lobe-like spurs on the posterior margins of

the second and third coxje are very slight, being almost imper- 

 ceptible. 



Length of body (not including capitulum) '63 mm. ; its width 

 ■54 mm. 



Host'. Macroglossus minimus ; Gilolo. 



We have only a single specimen of this new mite in the 

 collection.

$ . The whole dorsal surface is rather strongly chitinized, and 

 it is difficult therefoi-e to see the outline of the scutum itself. 

 There are a number of shallow pits on the surface of the scutum. 

 Ohfetotaxy of dorsum much as in A. lateralis, but the hairs seem 

 shorter. Process on dorsal surface of capitulum rounded instead 

 of conical as in A. lateralis, etc. Jugular plaque strongly 

 chitinized and elongated transversely, being much wider than 

 long. Sternal plate almost flask-shaped, for it is roughly oval in 

 shape, with a short anterior neck-like portion^ It is smooth, 

 being without markings, except for two pairs of minute punc- 

 tations, and there are three pairs of hairs on it. Genito-veniral 

 pl(,ite very short, rounded ofF posteriorly and bearing a pair of 

 hairs. Hairs on venter very sparse as in A. lateralis, and although 

 •quite short tliey are longer than in that species. In unmounted 

 specimens there is sometimes a slight but noticeable swelling on 

 each side of the venter just before the posterior end of the body. 

 Paired spines or hairs at posterior end of body minute and 

 inconspicuous, being much smaller than in P. lateralis. First leg 

 enlarged ; the lateral setas are very like those of A . lateralis, and 

 there is a terminal pair of paddle- shaped setae as in that species.
