was not quite certain, as this would only have increased the con- 

 fusion. If the identity of one or the other of the species published 

 by me, with a previously described one, should be satisfactorily 

 proved, I will always be ready to grant to the older name the 

 priority over mine.

MESERITZ, July 1, 1862. 



REMARKS. I have a few words to add respecting the translation of this 

 work, which was done under rny care. The terminology used has 

 throughout been that adopted in the first volume of these "Monographs." 

 The term antennal bristle alone has been replaced by the shorter one, arista, 

 used by English writers. It will perhaps not be ainiss also to explain 

 the sense of the terms fore and hind and their difference from anterior 

 and posterior when applied to the feet or parts of the feet. 



By fore feet (coxae, femora, tibise and tarsi), corresponding to the German 

 vorderste Beine and the Latin pedes antici, is meant the first pair of feet 

 (or coxae, etc.)- 



By anterior feet (corresponding to vorderen Beine, pedes anterior es), the 

 two first pairs are to be understood. In this case, however, in order to 

 avoid all possible misunderstanding, Mr. Loew has almost always used the 

 expression "the four anterior feet," which was retained in the translation. 



The same rule applies to hind (hintcrxir, pnstici) as indicating the last 

 pair, and posterior (Jiinttre, posteriores) meaning the two last pairs.
