by the same author gave synopses of the Scolopendridae of our region 

 based largely on the collections of the U. S. National Museum. Mr. 

 Jerome McNeill published (1887) two papers in the tenth volume of the 

 Proceedings of the U. S. National Museum ; in these eighteen new spe- 

 cies were described. A third paper published in 1888 added another 

 species, Polydesmus butleri, to the Indiana fauna. This brings the 

 summary of literature to the time when Mr. Bollman first commenced 

 his publications. It will be seen that the work on the myriapoda of 

 the United States consists largely of fragmentary papers scattered 

 among the scientific periodical literature of several languages. Only 

 one work — that of Dr. H. C. Wood — made any attempts at complete- 

 ness, and that had been published almost a quarter of a century. The 

 time was ripe for some one of keen observing powers and careful judg- 

 ment to collate these species already described, and collect and de- 

 scribe the new forms that had been or could be found. Into this work 

 Mr. Bollman entered with enthusiasm, and his activity is shown in the 

 numerous papers that in so short a space came from his study. In 

 addition to the papers published in the Proceedings of the U. S. Na- 

 tional Museum and reprinted in this volume, Mr. Bollman published 

 seven papers : two in the Annals of the New York Academy, one in the 

 American Naturalist, and four in Entomologica Americana. In these 

 papers are included descriptions of thirty-one new species, many of 

 which were collected in the vicinity of his home in Indiana. In addi- 

 tion three new genera were described.* 



The anatomy, morphology, and development of the Myriapoda have 

 remained almost untouched in America and comparatively little has 

 been written anywhere. Its single paper by Packard on the morphol- 

 ogy comprises about all the American literature on the subject. A 

 few brief notes on the poisonous nature of some of the more common 

 species have appeared from time to time. The economic relations of 

 the Myriapoda have been only briefly considered. Besides scanty 

 notes on the habits of certain species scattered through the papers of 

 Wood and others mentioned above, we add a brief summary of what 

 is included in the serial entomological reports of the various States. 

 In his Tenth Report on the insects of New York, Fitch describes the 

 ravages of Polydesmus complanatus t in cabbage, causing the so-called 

 "club foot." Walsh, in the Practical Entomologist for 18G6, describes 

 Julus multistriatus, which he afterwards identified as J. ceruleocinctus 

 Wood,J as causing injury to strawberry roots. In the American Ento- 

 mologist for 1869, he mentions two forms, a Julus and a Polydesmus, as 

 burrowing in strawberries. In the Eleventh Illinois Report (Thomas) 



* Adding to these the species described in the Proceedings of the U. S. National 

 Museum and the extent of Mr. Bollnian's work on the Myriapoda is apparent; the 

 totals will then be 3 genera and 63 species.
