from the Fallen and Zetterstedt descriptions. The lectotype is complete and in 

 excellent condition except for a few threads of mould; examination of it confirms 

 that Carcelia (Senometopia) excisa (Fallen) has been correctly understood by later 

 authors. 



Tachina titan Walker, 1849 : 735- 



Described from an unstated number of specimens of unstated sex from one locality 

 (Silhet). The type-material consists of two <$ syntypes, of which one is here designa- 

 ted. LECTOTYPE S, Bangladesh: Sylhet [= Silhet] (in British Museum (Natural 

 History), London). Paralectotype $, same data and depository as lectotype. 



The lectotype bears a circular label with the figures '45-107' in faded black ink 

 on one side (signifying the 107th serially numbered collection received at the British 

 Museum in 1845) and 'Silhet' on the other, a pencilled label in Austen's hand reading 

 'Sylhet, India. Purchd. fr. Revd.-Stainsforth. 45.107.', and a circular green-edged 

 type label on which Austen has written the name in black ink. The paralectotype 

 is labelled similarly except that it lacks the green-edged type label. 



Tachina tepens Walker, 1849 : 723. 



Described from an unstated number of specimens of unstated sex from Silhet 

 and from an unknown locality. Two $ syntypes in BMNH are evidently the entire

 in 1845) and 'Silhet' on the other, a pencilled label in Austen's hand reading 'Silhet, 

 India. Purchd. fr. Sowerby. 45.33.', and a circular green-edged type label on which 

 Austen has written the name in black ink (on the reverse side). The paralectotype 

 has a handwritten label reading 'Locality ?', and another label that reads on one 

 side 'One of Walkers series so named.' with 'EAW' added in ink and on the other 

 'Tachina tepens Walk.' in an unrecognized handwriting. 



Thelairosoma secundum Villeneuve, 1929 : 66. 



Described from an unstated number of specimens from a single locality, and 

 with only the <$ sex mentioned. Two $ syntypes have been seen, but there may

 (H. Sauter) (in Deutsches Entomologisches Institut, Eberswalde). Paralectotype 

 cJ, same data as lectotype except month date vii (DEI).
