 magnificent work on the group of Thrips insects. It is written in the 

 Bohemian language, but the descriptions of species and other systematic

 281 pages, describes all the species known to the author, 138 in number, 

 distributed among 36 genera. Of these 138, 117 are European, many 

 being now first described. The second (Paleontological) part, 16 pages, 

 summarizes what is known of these insects in past time. The third part, 

 34 pages, is devoted to the anatomy, the fourth, 20 pages, to the develop- 

 ment. A consideration of habits and habitats forms the fifth (biological) 

 part of 18 pages. The sixth (economic) part, 20 pages, treats of the 

 plants affected by the Thysanoptera, the seventh (historical) part, of 62 

 pages, comprises a complete bibliography for the Order with abstracts of 

 the contents of each paper. Full indices complete the volume.
