 Erster Theil : Rhynchota frontirostria, Zelf. (Hemiptera heteroptera, 

 Aut.),'" von Dr. Gustav. Flor. Dorpat, 1860. 



In this volume of 820 pages the Livonian Heteroptera are well 

 described. The older and generally-accepted genera are retained, 

 modern subdivisions being given as subgenera ; the specific syno- 

 nymy is very full, and appears to have been worked out with much 

 care.

 analytischen Methode bearbeitet,' von Dr. Franz Xaver Fieber , 

 mit zwei lithographirten Tafelu, Wien. 1861. 



The analytic system followed in this elaborate work appears to 

 have rendered necessary the reduction of generic value to the lowest 

 point, consequently an infinite number of new genera has been 

 created, established for the most part on very small structui'al dif- 

 ferences, so that a great portion of the genera contain only a single 

 species each ; the result being that a vast amount of descriptive matter 

 has to be kept in mind in order to arrive at a certainty upon 

 any given point, and, contrary no doubt to the intention of the 

 author, the facility of determination is rendered very difficult. The 

 synonymy of the species is full, but the method of printing it in
