(7) Augochlora confusa Rob. Two 9. These differ from a specimen 
received from Mr. Robertson in having the basal area of metathorax 
bounded by a sharp rim, but Robertson’s description indicates that 
such specimens occur also in Illinois. The species is new to New 
Mexico. 
(8) Osmia pusilla Cresson, one $; Osmia, two new species, males. I have 
sent these to Mr. Titus, who is revising the genus. 
Las VEGAS Hor SPRINGS. 
Verbena macdougalii was visited July 11 by bombyliid flies, 
Systoechus vulgaris Lw. (det. Coq.), as observed by Miss M. 
Holzman. 
Ribes cereum Dougl. was visited May 24 by Bombus juxtus 
Cresson. 
I will take this opportunity to record from Las Vegas Hot 
Springs the dragon fly Hyponeura lugens Hagen. Prof. J. A. 
Needham, who kindly identified it, states that the genus is new 
to the United States, but there are specimens from Arizona 
in the Cornell University collection, not hitherto recorded. 
APPENDIX. 
Two New Species of Osmia. 
The two new species of Osmia collected on flowers of Iris at 
Trout Spring, N.M., were sent to Mr. Titus with the expecta- 
tion that they might prove identical with species which he had 
already described in MS. As this is not the case, they are 
briefly diagnosed below. Some additional notes and comments 
will be given by Mr. Titus when he publishes his revision of 
the American species of Osmia. 
Osmia iridis Cockerell and Titus, z. sf.
