TACHINIDAE OF ORIENTAL REGION 267 



from Formosa that lack type-status. Each bears a Baranov determination label, 

 one is from Kankau, ix.1912, and the other from Tainan. 



Echinomyia deludans Villeneuve, 19366 : 4. 



Described from three <$ syntypes from Tibet and Szechwan. Only the Szechwan 

 specimen has been located. LECTOTYPE $, China: Szechwan, Chetu Pass, nr 

 Tatsienlu (D. C. Graham) (in United States National Museum, Washington D.C.). 

 The lectotype bears Villeneuve's original label reading 'Echinomyia deludans 

 Villen.'. 



Echinomyia punctocincta Villeneuve, 19366 : 4. 



Described from 'plusieurs individus' £ from 'Szechuen (Chine)'. LECTOTYPE 

 <$, China: Szechwan (D. C. Graham) (in United States National Museum, Washing- 

 ton D.C.). Paralectotype g, same data as lectotype (seen in Mesnil coll. 1966, 

 ? now in CNC, Ottawa). The lectotype bears Villeneuve's original label 'Echino- 

 myia puncto-cincta Typ. Villen.'. 



Mesnil's collection, when studied in 1966, contained (in addition to the above- 

 mentioned paralectotype) one 9 and 2 <$ specimens from Si Gi Pin, Mt Omei, Szech- 

 wan (D. C. Graham), but Villeneuve did not specifically record this locality and 

 these specimens are considered not to be syntypes. Their present location is not 

 known to me. 



Echinomyia rubrapex Villeneuve, 19326 : 268. 



Described from three $ syntypes stated to be from Toyenmongai, Formosa. 

 Some uncertainty exists concerning the type-, or probable type-material. Two 

 specimens have been located that appear to be original syntypes: a $ in the BMNH 

 collection that is from the stated type-locality (Toyenmongai) but does not bear 

 a label of Villeneuve, and a $ in the CNC collection (ex coll. Villeneuve-Mesnil) 

 that bears Villeneuve's original label as a type but is from Polisha, not Toyenmongai. 

 The probability is that, despite no mention of Polisha in the description, Villeneuve 

 had the Polisha specimen before him at the time of description, and his label clearly 

 indicates that he regarded it as a type. The specimen from Toyenmongai now 

 in BMNH collection, stood in the Villeneuve-Mesnil collection with the Polisha 

 specimen and was given to me by Mesnil in 1966 for the BMNH; it is here held to 

 be an original syntype, although there is no direct evidence - because it does not 

 bear a Villeneuve label - that it has this status. In designating a lectotype it is 

 preferable to choose the specimen labelled as type by Villeneuve, even though there 

 is a discrepancy between its locality on the label and that cited by Villeneuve in 

 the description; such designation also ensures that the primary type stays in the 

 CNC collection with other primary types of Villeneuve that reached there via 

 Mesnil's collection. 



LECTOTYPE $, Formosa: Polisha [not Toyenmongai], xii.1908 (Sauter) (in
