CATALOGUE AND SYNOPSES. 



In giving a synopsis of this family whose members have such 

 a wide geographical distribution, it is often a considerable 

 task to bring the genera and species of the various authors into 

 their proper relation to each other. The pattern of the thoracic 

 macrochastse has been most constantly and consistently used 

 by the German systematists as a distinguishing character and 

 has reached its perfection in the slightly conventionalized 

 drawings used by Professor Becker m his monograph of the 

 family in the Berliner Entomologische Zeitschrift for 1896, 

 in which many of the genera are very briefly and concisely 

 separated by this method. The fact that it has been largely 

 overlooked by many English and American writers makas it 

 quite difficult to define the generic limits of this family which 

 is so well represented in both Europe and America, and also 

 renders uncertain to those not familiar with the specimens the 

 exact relation of a new genus to those already established, not
