Andronicus cylindricus Cresson.

n. 6, 9 (Megachile brevis).

chile brevis) . 
1888: Add. Fauna Ent. Can. Hym. p. 324, .327 n. 12, p. 
467, 9 (Osmia spoliata) : p. 462 (Megachile brevis). 
1^96: Dalla Torre, Cat. Hym. v. X, p. 412, 9 (Osmia 
spoliata); p. 422, 9 (Megachile brevis, Prov. references). 
I have examined two females, one numbered 1478 and 
labelled Osmia spoliata Prov., the other 1014 and labelled 
Megachile brevis. Although Provancher in 1883 refers to the 
cT of Magachile brevis there are no specimens in the material 
sent me. Since the c? of this species is so readily separated 
from others closely related, by the shape of the antennae it is 
likely that the reference is to another species. 
1888: Add. Fauna Ent. Can. Hym. p. 330-331, n. 23, cT, 
p. 447, (Andronicus cylindricus). The above reference is to 
a species reported from Ottawa and Cap Rouge by Provancher. 
I have not seen the specimens mentioned, but the reference 
is doubtles correct, since the c? of this species is easily 
recognizable. 
Heriades carinatum Cresson.

1883: Fauna Ent. Can. Hym. p. 717, 9. 
1888: Add. Fauna Ent. Can. Hym. p. 457. 
1896: Dalla Torre, Cat. Hym. v. X, p. 375, 9 (Provancher 
reference) . 
I have examined two 9 9 and one cT of this species, num- 
bered 879 and recorded from Cap Rouge and St. Hyacinth. 
Chelostoma ? calif ornicum Cresson. 
1895: Le Naturaliste Canadien, v. XXII, p. 190, 9 , c? 
(Heriades albicinctum) . 
There is a single cT specimen in the Provancher collection, 
that I have seen. Provancher mentions and describes both 
c? and 9 and records them from Los Angeles, Cal., collected 
by Mr. D. W. Coquillett. The male bears the number 1733. 
The female described by Provancher has two teeth on the 
clypeal margin and a white scopa. 
Chelynia Provancher.

gidae, type labiata).
