was sent to Abbe Provancher by Mr. Coquillett who does not 
now remember whether it was returned or not. From the 
description the species appears to be a specimen of Monumetha 
albifrons Kby.

Length 6 mm. Black; about the size and shape of Micro stelis lateralis, 
finely closely punctured, except clypeus on which the punctures are 
coarse; clothed with fine white pubescence, vertex of head and disk of 
thorax almost bare but with scattering pubescence, face, cheeks, pleura 
and thorax beneath thickly clothed, first tarsal joint clothed densely 
beneath, abdominal segments 1-4 with narrow apical hair bands, inter- 
rupted on segment i, missing on segment 5, sides of all the segments fringed, 
scopa very scanty; clypeus with minute indentation in central apical 
margin, a tuft of hair projecting from beneath on each side, mandibles 
reddish at tips, two teeth only visible; antennae fuscous beneath; legs 
reddish-brown (only one front leg, one middle leg minus claws, one hind 
leg and femora of the other present) ; tegulse tinged with red, veins .of 
wings fuscous, wings very slightly cloudy. 
Redescribed from one $ specimen in the Provancher col- 
lection numbered 1521 and reported by Provancher from Cap 
Rouge. 
This is a very neat little species, and is apparently a good 
species of Alcidamea. The teeth of the mandibles are not 
fully visible, but the wing-venation and structure of base of 
first abdominal segment will place it in this genus.

445> $ i <3* (Alcidamea pilosifrons) . Pro vancher's descriptions 
above noted may be considered as placing the species referred 
to in the above reference under this species. I have not seen 
the specimens which he states are from "Ottawa (Harrington)."
