so on. This procedure was adopted because thc true basal tergite 

 is more or less fused with the second, and in many species is in f act 

 scarcely discernible, so that the second tergite often appears to 

 be the first. But in the present paper this method is abandoned, 

 and the true basal tergite is reckoned as tergite 1 (even if not very 

 distinctly separated from the second), the true second as tergite 2, 

 and so on.

This species is represented by a series of 9 (J and 7 ?. I can 

 see no distinguishing marks between them and some specimens 

 before me from Eastern Algeria. The principal interest of the 

 series lies in the fact that it demonstrates how wide the ränge of 

 this species is (as is also the case with the series of Nycteribia pe- 

 dicularia discussed below). It was previously known from many 

 parts of Europe and from North Africa, andnow that it is known 

 from Formosa, it will not be surprising if its ränge is found to 

 include many other localities.

The (J of this species was first described by West wood, andhis 

 description was merely quoted by Kolenati, who had not himself 

 seen the species. The $ was redescribed by Speiser. In 1908 

 I studied a few specimens of both sexes collected by Sauter in For- 

 mosa. I described and figured the $ for the first time, and also gave 

 new figures of thc $ abdomcn and some notes on this sex. Now that 

 the whole of Sauter's material has been submitted to me, there 

 isiound to be among it a very large series of both sexes of this species.
