 XXXII. SUPFLEMENTARY REMARKS TO EARLIER PAPERS. 



The following notes relate in large part to additions recently made 

 to the Canadian fauna through the activity of collectors in the Dominion. 

 Several species which their possessors were unable to identify by means of 

 the tables have been submitted to me, and, proving new to the Canadian 

 lists, are incorporated in these pages, that students may have access to 

 the descriptions. The families are taken up in the order of their treat- 

 ment in the Canadian Entomologist. 



COCCINELLID^. 



In this family a great number of additions, comparatively speaking, 

 have been made. Some of these are first recorded in Dr. Horn's 

 memoir, entitled " Studies in Coccinellidse," published in Trans. Am. 

 Ento. Soc, Vol. XXII. Among them may be noted Smilia misella and 

 several species of Scymmis. 



Smilia is substituted for Pentilia, hitherto employed in our lists ; 

 and the Canadian species, ^. misella^ Lee, is the smallest Coccinellid 

 known from the region, measuring only .04 inch in length. It is 

 shining black, not pubescent, convex, prothorax a little narrower 

 than the elytra, smooth, sides not explanate. Elytra distinctly punctured, 

 suture finely margined. Behind the front angles of the prothorax is an 

 indistinct obliquely impressed line. Dr. Leconte states that it is some- 

 times abundant on flowers of Thalictrufn. It is more than probable 

 that 6". marginata, Lee, will also be found in Canada, in which case 

 it may be recognized by the obliquely impressed thoracic line being 

 distmct and the surface punctate. Both are about the same size. 



In the genus Bracliyacantha I have received two species not 

 hitherto recorded from Canada. Mr. John D. Evans sent a specimen of 

 B. 4-punctata^ Melsh., taken in Eastern Ontario. Without reference to 

 the generic characters this insect would probably be placed in Hyper- 

 aspis, but the anterior tibise have a spine on the outer margin. It is 

 about the size of B. ursina, black, the tibiae and tarsi pale. Each 

 elytron bears two round reddish or orange spots, one basal, one sub- 

 apical ; these spots being separated from the suture by a space about 

 equal to their own diameters. The male has besides a narrow anterior 

 thoracic marginal line and humeral elytra! spot yellow. From Mr. R. J.
