the Philippines agreeing with Herve-Bazin’s figure of 
Syrphinella in that the veins are markedly infuscate. More- 
over they agree in the lack of translucent window to ab- 
domen, and in having the fourth abdominal segment yellow- 
ish posteriorly and more or less golden pilose over the whole 
width. Thus they are very close to Syrphinella if not iden- 
tical. But they have the third antennal joint distinctly 
pointed. P. novus, and the figure of miranda in nowise agree 
in this particular. De Meijere has described three other 
species in this genus from Java, New Guinea and Borneo, so 
that there may be many species. Sack has described what is 
probably a synonym of miranda under the name Mixogaster 
cinctella Sack. 
Paramicrodon delicatulus n. sp. 
This species differs from Microdon flukei Curran in the 
general bluish purple color, as well as other particulars. 
Pile above antennae on vertex and occiput silvery, narrowly 
black below ocelli in the front. The antennae are wholly 
orange, whereas they are brown in flukei with a black third 
joint. Abdomen unicolorous purplish, with the basal red 
color of flukei. 
Two males. Soledad (Cienfuegos) , Cuba, August 6, 1920 
(N. Banks). Type in the Museum of Comparative Zoology. 
Paratype in the author’s collection. 
Pseudomicrodon n. gen. 
Head short to quite short. In profile, occiput above mod- 
erately or considerably thickened. Antennae situated above 
the middle of the head in profile, quite elongate in form. The 
first joint about as long or longer than remaining two, 
though obviously proportions in length must vary over some 
latitude in Microdontine antennae. Face gently convex. 
Cheeks inconspicuous. Vertex rarely protuberant. Abdo- 
men rather strongly pedunculate; the segments after the 
second fused into a beautiful, oval, cylindero-convex body, 
which is widest on the fourth segment, rounds off posteriorly, 
tapers gently forward anteriorly, and is strongly flexed 
downward at the second segment, practically held at right 
angles. Scutellum usually bears two fairly well developed 
teeth or points. Hind femora usually only moderately thick-
