576 MAJOR E. E. AUSTEN ON TUE 



A. picta Wied., and indeed, so long ago as 1908, the present 

 writer placed a manuscript note in the Museum collection 

 ■drawing attention to this identity. 



The species under discussion is represented in the Hope Depart- 

 ment of the Oxford University Museum by two $ $ , one of 

 whicli is of ordinary size (total length, including ovipositor and 

 facial beak, 41-2 mm. ; wing-expanse 73 mm.), while the other 

 is a diminutive example, with dimensions (total length, including 

 ovipositor and facial beak, 29 mm. : wing-expanse 50-5 mm.) much 

 below normal. Both specimens are unfortunately without locality 

 labels; the larger of the two is labelled " Miers coll.," while the 

 other, probably collected by Bates on the Amazons, bears a label 

 in Westwood's handwriting, with the words " E Mus. Saunders. 

 1867." 



In the wing-marking of Fanlophthahuus pictus a. characteristic 

 feature is a broad, dark brown, Li-shaped blotch, the shoi'ter arm 

 of which meets the costa in such a way as to include the tip of 

 the mediastinal vein, while the longer arm embraces the thiid 

 longitudinal vein between the anterior transverse vein and the 

 bifurcation of the former, without being in contact with either. 



Fiebrig's interesting observations on the preliminary stages 

 atid bionomics of " ^. teretruncum" have already been referred 

 to (vide suj'ira, p. 556). 



Pantophthalmus chuni Enderl. 



Acanthomera chuni Enderlein, Zool. Anz., Bd. xli. ' no. 3, 

 pp. 102, 103, fig. 4 (December 20, 1912). 



This fine species — described by its author from two $ $ from 

 Peru, in the Zoological Museum, Stettin — is represented in the 

 National Collection by a single $ from lirazil (11. Amazons — 

 precise locality unknown: IT. W. Bates), measuring 42 mm. in 

 length from the tip of the prominent facial beak to the end of 

 the ovipositor, and having a wing-expanse of 70*6 mm. On the 

 second and third abdominal tergites, conspicuous against the 

 velvety-black or sooty-black gro\ind- colour, are half-a-dozen 

 specimens of the Acarid pai-asite already noticed in connection 

 with several other species. 



By the courtesy of Dr. Hugh Scott, the writer has been per- 

 mitted to examine a 5 of this species in the ITniversity Museum 

 of Zoology, Oambi'idge. Except that its dimensions (length from 

 tip of facial beak to end of ovipositor 29 mm., wing-expanse 

 53"75 mm.) are much below normal, this example, which was 

 likewise taken on the River Amazons {Nevile Goodmcm, 1879), 

 agrees with that already mentioned. 



In spite of certain apparent discrepancies, there can be no 

 doubt as to the correctness of the identification of the Brazilian 

 specimens i-eferred to above. The description of P. (Acanthomera) 

 chuni furnished by Enderlein is seriously misleading in more than 

 one respect. In the first place the German author speaks of the
