Portevin 24, 25, 26; Hatch 25. 27, 20; Fall 25-26-27; Van Dyke 2S; 

 Brown 28, 30; Bradley 30. 



Hatch 27, p. 341 following Portevin, defines subspecific variations 



as follows: 



1. correlated with geographical distribution = subspecies; 



2. variations in color pattern =2 at)erration; 



3. variation in sculpture and color of pubescence = variety; 



4. variation in the general pigmentation of the exoskeleton = accident. 



The use t)f the term "aberration" in this restricted sense, is not in 

 accord with the older dictionaries, but may come to be generally ac- 

 cepted. We have not numbered the names thus designated by their 



authors.

• As restricted by Hatch, this family includes only the tribes Lyrosomini. Agyrtini. Pinodytini 

 (name chanffed to Catopocerini), and Silphini of the 1930 catalogue. The other tribes form a new 

 family Leiodids. the separation of which is apparently supported by Dr. Forbes' studies of wing 

 venation and folding, and adopted in Bradley's Manual. The composition of these families may 

 suffer changes; they are here treated in accordance with the literature cited.
