3. Arizelomyia/' new (jemis. 



Type. ~ Muxcieai>(i hit! rosfi'ls Raffles. 

 . Rill depres.sed, the culmen nearly straight except at the uno-ulate 

 tip; rictal bristles nioderately developed; exposed euluieii e(|ual to 

 middle toe without claw; tail about three-fourths of wiug; wino- pointed, 

 the second primary longer than the sixth; three primaries sinuate on 

 their outer webs; tirst (outermost) primary decidedly (at least 5 mm.) 

 longer than pi'imary coverts. 



Til is genus differs from AlKe<>na,i\ with which it has been conunonly 

 associated, in the following particulars: Bill narrower; rictal bristles 

 usually not so well de^■eloped; only three primaries sinuate on their 

 outer vanes; wing more pointed, the second primary longer than the 

 sixth. From Ifusc/mjHi it may be distinguished by its relatively 

 longer tail, long outermost primary, and broader bill. 



The type species, Arizelomyia latirostris (Raffles), is the only one now 

 certainly referable to this genus, though Alseonax •muttid (Layard) 

 may prove to ])elong here; MuHcivajxt raficauda of Swainson, which 

 has been examined, is not congeneric with Arizelotnyia latiroHtina. 



4. Alseonax. 



J/.sro);fu' Cabanis, Mus. Hein, I, 1850, p. 52 (type, Bidalis aduMn Boie). 



l)ill ])road, much depressed, the culmen almost straight except at 

 the decurved tip; rictal bristles strongly developed; exposed culmen 

 about equal to middle toe without claw; tail about three-fourths the 

 length of wing; wing rounded, the second primary al)out equal to the 

 seventh; four primaries sinuate on their outer webs; outermost pri- 

 mary decidedly (more than 5 mm.) longer than primary coverts.
