PRISTIRHYNCHOMYIA, mihi, gen. nov. 



With the exception of an important modification of the pro- 

 boscis, identical with PhilcEmatomyia, Aust., the general characters, 

 the venation and chaetotaxy agreeing exactl3\ 



The two parts of the proboscis, however, are structurall}^ re- 

 versed, the wide basal part being fleshy and flexible, the second 

 part (of about equal length) being sub-c^^lindrical, black and 

 distinctly chitinized, possibl}^ retractile to the extent of its with- 

 drawal partly or wholly within the fleshy basal portion. At the 

 end of the chitinous portion is a soft flesh}^ tip, the terminal 

 orifice being of the shape of a triangle with a rounded base (the 

 edges being thickened somewhat by a rim bearing the teeth). At 

 the apex of the triangle is a singl:^ black tooth, whilst arranged 

 around the orifice above are three pairs of similar black teeth. 



Under high microscopic power the apparent ' ' rim " of the 

 orifice is seen to be the base of each tooth extended considerably 

 on each side, so that the " rim " is not continuous. 



The new genus is intermediate between PhilcematoDiyia and 

 Musca^ but the presence of the teeth suggests that it can hardly 

 be other than a " biting fly." 



Pristirhynchomyia lineata, mihi, sp. nov. 



$ . Calcutta. Long. 4-5 mm. 



Head. Yellowish grey, whitish grey when viewed from below. 

 Frons at level of antennae J width of head, slightly narrower at 

 vertex ; with a broad dull black median stripe (widest in the middle). 

 Vertical triangle blackish, distinctly raised, with 3 pairs (rarely 4) 

 of bristles, the ui)per pair small, the lower i)air strong and long. 

 Normally 7 strong fronto-orbital bristles placed along the edge of 

 the black centre .stri])e, above these are two very minute ones, with 

 a powerful one above these, this latter one being level with the 

 centre of the ocellar triangle. The upper strong bristle, and the 

 7 large fronto-orbital ones are always ])rcsent. 



Outside this row is an irregular row of very small but distinct 

 bristles. Two minute vertical bristles, and a pair of strong ones on 

 vertex near the upper corner of each eye. Antennae blackish grey, 

 3rd joint lighter ; 2nd joint with several short stout bristles and 

 one much stronger one. Arista cf)nsiderably thickened at base ;
