AUSTRO-MA.LAYAN DIPTERA 420 



Agrees with description and figure. In Vienna, I saw several 

 types of Doleschali, but only one of them entirely agreed with 

 my specimen , in other words , only one of them was a true 

 type of the species. When Schiner Yerh. Z. B. Ges. 1867 p. 381, 

 on the strength of one of these types, says that the wings of 

 tristis are altogether black ( « ganz und gar schwarz » ), he over- 

 looks Doleschalls description (« alis ima basi pellucidis »), as 

 well as his figure, where the wing is hyaline nearly as far as 

 the discal cell. So much for trusting types, apart from descrip- 

 tions. 



Laphria Taphius Walk. List etc. II, 380 ! (Philippine islands , 

 Celebes, Amboina). 



Two specimens ; Kandari, Celebes, April 1 874 (Beccari). 



Exceedingly hke the preceding species, but differs in the front 

 tibiae being beset with whitish pile, and in the hyaline portion 

 of the wings being less extended. I compared my specimen «with 

 that in the Br. Mus. which bears MS Walker's label. 



Laphria obliquistriga Walk. J. Pr. Lin. Soc. V, 264 ! (Celebes). 



One d^; Kandari, Celebes, April 1874 (Beccari). 



Agrees with the description, and I find in my notes, taken 

 in the Br. Mus. that the identity may be considered as certain. 

 M.'^ V. d. Wulp's ohliquistriga must be , I suspect , a different 

 species ; several points in the description are not applicable , 

 especially the direction of the veins closing the discal and fourth 

 posterior cell, which form one line in my specimen. The relation 

 of this species to L. scapularis Wied. remains to be investi- 

 gated, as his type was a female ; while Walker's specimen and 

 mine are males. Wiedemanns description disagrees in several 

 respects. 



Laphria sp. One 9. Ramoi, N. Guinea, Febr. 1875 (Beccari). 



Related to L. ohliquistriga; wings much darker, and of the 

 same bluish-brown coloring up to the root ; no silvery spots 

 on the thorax, mystax more dense etc.
