N. alboclavata Bigot 
1888. Miss. Scient, Cap. Horn., Dipt, vi, 41, (Cape Horn). 
If this is a Notiphiline it is unique in having the coxae and 
femora yellow. 
X. argentata Walker 
1856. Ins. Saund. v, 407, (United States). 
This belongs to the genus Brachydeutera. 
N. avia Loew 
1878. Zeit. f. Ges. Naturw., li, 193, (Hudson Bay Territory). 
This seems to be allied to loewi. i\Iy material is lacking in 
any series from central Canada. 
X. bella Loew 
1862. Mon. Dipt. N. Amer., i, 135, (Middle States). 
See the synonymy under nudipes. 
X. bellula Williston 
1896. Trans. Ent. Soc. London, 1896, 390, (St. Vincent). 
See the synonymical note under punctifera. 
X. brasiliensis Walker 
1856. Dipt. Saund., i, 408, (Brazil). 
This is not a Notiphila, judging from the length of the antennae 
as described. 
X. carinata Loew 
1862. Mon. Dipt. N. Am., i, 137, (Middle States). 
The description of this species, based on a female, suggests 
furcata. I hardly think it could be associated with riparia. 
X. CO stalls Walker 
1856. Dipt. Saund., i, 408, (Brazil). 
This evidently does not belong here. The long antennae, the 
“row of bristles along each eye” and the maculate wings are not 
characteristic of this genus. The description suggests Scatella or 
an ally. 
X. decorata Williston 
1896. Trans. Ent. Soc. London, 1896, 389, (St. Vincent). 
The black second joint of antennae, the yellow base of third 
and the quadriseriated abdominal marking suggests affinities with 
vittata Loew. 
X. decoris Williston 
1893. N. Amer. Fauna, vii, 258, (Panamint Valley, California). 
The description suggests species of Agrolimna, probably allied 
to occidentalis or olivacea.
