The number of families represented in this catalogue is 50 ; num- 

 ber of genera, 261 ; number of species, 484, three numbers in the 

 catalogue not representing Europa- American species. Of this num- 

 ber 328 occur in Asia, 40 of which are not recorded, so far as I have 

 observed, with a European habitat. 



An opinionative estimate of the derivation of these species is : 

 native, 278 ; introduced (from Europe, except three), 156 ; in doubt, 

 50. Of the introduced species about 60 are insects of commerce, 

 leaving 96 as the number of accidental importations. Of these 

 many are naturalized beyond a doubt, but others are still on j)robation. 



Note. — 74. Agabus longulus is uot the same as A. dissimilis, coniparisou 

 with the LeConte type having been made by Dr. Horn while this was passing 

 through the press.
