Hugh Scott: 



comprehensible in the light of the following note made by Sauter, 

 which indicates that the bulk of the material was found in an old 

 temple where bats congregate in large numbers. I give the note 

 verbatim, as received through Dr. Horn: „Die Tiere dürften wohl 

 alle Miniopterus schreibe? si als Wirt haben, obwohl ich bei der 

 großen Aufsammlung (in einem alten Tempel) auch von Myotis 

 taiwanensis und Pipistrellus abramus Nycteribiiden abgelesen habe ; 

 die beiden letzteren Arten hingen vereinzelt unter den Miniopterus, 

 sodaß die Parasiten bequem von einem Wirt auf den anderen über- 

 gehen respektive sich verirren konnten. Myotis und Pipistrellus 

 sind, wenn einzeln gefangen, meist völlig frei." 



In the collection far the most abundant species is Nycteribia 

 allotopa, represented by a great number of specimens: next in 

 abundance is Penicillidia jenynsi, and third comes Nycteribia 

 parvula, both represented by very long series: very much less 

 numerous are Nycteribia pedicularia, represented by 44 specimens, 

 and Penicillidia dufouri, represented by only 16 specimens. 



Variation. Examination of the long series of Formosan 

 material shows that there is some Variation in the quantity of 

 bristles on the surfaces of certain of the abdominal plates. In 

 four out of the five species (i. e. in all except Penicillidia dufouri) 

 it was found that the 2nd tergite of the $ has its surface quite bare 

 in some specimens, but bearing a greater or less number of short 

 bristles in others. Similarly in the <J of Nycteribia allotopa the 4th 

 tergite has its surface quite bare in some specimens, bearing short 

 bristles in others. Likewise the isolated very long bristles, and 

 short thorn-like bristles, on the hind margins of certain segments 

 may vary in number and position. Thus in N. parvula $ the very 

 long bristles on the hind margin of the chitinous tergite before 

 the anal segment may be 4 or 6 in number; and in N. pedicularia 

 the short thorn-bristles on the hind margin of the 4th sternite vary 

 considerably in number. Therefore, in determinations made from 

 few individuals, too much reliance must not be placed on whether 

 certain tergites are bare or bristly on the surface, or on the exact 

 numbers of thorn-bristles, &c. 



In my earlier paper (op. cit., p. 362) I gave some description 

 of a larva of Penicillidia jenynsi. In the larger material a number 

 of of more than one species were found carrying larvae in 

 various degrees of extrusion from the abdomen, but time has 

 prevented a detailed examination of these being made. Some 

 specimens of Penicillidia jenynsi bear fungi of the order Laboul- 

 beniaceae, and a note on the occurrence of these organisms on 

 Nycteribiidae is given under that species. 



Note on the numbering of the abdominal tergites. 

 In my descriptions of the $ of N. insolita and N. sauteri (op. cit., 

 pp. 365, 367), the first and second tergites were reckoned together 

 as tergite 1, and the true third tergite was called ,, tergite 2", and
