also a new Larra, very much like L . tenninata Smith both in shape and 

 color, but smaller. 



To these two new species must be added the three following : Larra 

 argentata Say, Z. Icevifrons Smith, and L. aixuata Smith. 



Order IX. PompilidcB. I caught this year 



Agenia calcarata Cress., and two other species of the same genus, one 

 pitch-black, of slender body, the other stout, with red abdomen, both new; 

 A new Pompilus, with abdomen and femora tipped with white, 

 And a ridiculously small, but most elegant Ceropales. 



Order XI. Scoliadidoe. A fine little Tiphia seems to be T. tarda Say. 

 Order XII. MiitillidcB. Only one specimen has been met with belong-

Order XIII. Foi-micidce. The only two genera of this Order noticed 

 before in Canada were Formica and Myrmica ; to the lists of their species 

 must be added 



Formica latipes ? Walsh. 



Myrmica opposita, Say, and 



Myrmica lineolata Say. 



Of other genera we have — 

 ^ Soknopsis fugax Latr., only i millimetre long, common to Europe and 

 America, caught in the Parliament's conservatory. 



Ponera contracta Latr., moreover 



4 new Formica have been found, 



I " Myrmica, 



I " Lasius, 



I " Leptothorax, and 



I " Atnblyopo?ie. 



But before describing most of those new insects. Abbe Pro vancher wants 

 the three sexes, which we do not yet possess. Of the last named he 

 writes : — "It is a tropical genera, new to North America." It is, therefore, 

 a most extraordinary find. 



Order XIV. Chrysidce. Four species of Chrysis are new to the list, — 

 of which one to science. The three before described are Chrysis bella 

 Cress., C. venusta Cress, and C. divergens Cress. 



Of the genus Cleptes, we have only one specimen, which belongs to 

 an undescribed species. 



There is to be added a new species of a genus not recorded before in
