While none of the patterns of the genera other than Cicindela are 

 of a type differing from the general plan of the Cicindela, patterns are 

 very often wanting or very simple, such as the simple cross bands in 

 Collyris. In course of the examination of the several collections named, 

 a great abundance of variation has been noted in some of the commoner 

 representatives of the groups, not only of Cicindela but others also. 



The taxonomic arrangement of Cicindela by Doctor Horn in the' 

 Genera Insectorum is especially fortunate. He has arranged the species 

 into a number of groups on the basis of the distribution of hairs on the 

 head, thorax, abdomen, tarsi, labrum, and of other structural character.-,, 

 but without reference to color patterns. He gives 174 groups apparently 

 not duplicated in the different regions and 16 represented in more than 

 one zoogeographic region by the same or closely related species. These 

 174 groups are distributed as follows: Ethiopian region, 34; Oriental 

 region, 48; Australian region, 22; Palearotic region which he extends 

 to include China, 20; Nearctic region, 24; Neotropical region, 26. The 

 groups found in more than one region and which are counted in the one 

 with most species, are as follows :
