THE CANADIAN ENTOMOLOGIST. 69 



In the genus Apathus, we have a large new species, with black 

 abdomen. 



Order II. We raise the number of Canadian A7idrenid<x from 120 to 

 T25, a dozen being new species, one of a new genus close to Stelis ; they 

 are : 5 AndreficB, 2 Halidi, i Heriades, 2 Sphecodes, besides another insect 

 which Abbe Provancher has, on a first examination, placed among th6 

 Anthophorce, but which, from its mouth-parts, seems to me to be nearer 

 A?idrena. 



Of Andrenidce described by Smith, we obtained : — 



Andrena clypeata, male, yellow-faced, rather common, originally found 

 in Florida. 



A. fragilis, remarkable for its immensely long mandibles, and 



A. victima. 



Anthophora margiiiata ? 



Melissodes nigripes. 



Megachile acuta, and the pretty little 



Stelis foederalis. 



Of species named by Cresson, we possess : — 



Halictiis disparilis and H. connexus. 



Andronicus cylindricus, whose male has very characteristic flattened 

 and toothed antennae. 



Alcidamea pilosifrons — the antennae of the male are also flattened, 

 but end in a sharp hook. The females of the two species have ordinary 

 clavate antennae. 



Orders III., IV, Vespidce zxi^ EumenidcB. New species, none, as well 

 as in the Orders VIII., Bembecidce, X., Sphegidce, and XXIV., Evanidce. 



Order V. Crabronidcz. Besides a new Philanthiis obtained by Mr. 

 Harrington, we add to the list : — 



Oxybelus interriiptus Cress., and O. emarginatus Say., 



Crabro chrysanginus St. Farg., Cr. obsairus Smith, 



Cr. producticol/is, Pack., and the diminutive 



Stigmus pusilliis Say. 



Order VI. NyssonidcB. Of this order of fine lively insects we add 

 Alyson melleiis Say, with yellow head and thorax, two new species of 

 Alyson, which would both be easily mistaken for the male Alyson oppositus 

 Say, and a very small Nysson, unspotted black. 



Order VII. Larrldce. What I had taken for a Nysson has been recog- 

 nized by Abbe Provancher to be a new species of Lyroda. I obtained
