by tho samo author jjavo synopses of tlio S{'oloi)eiidii(la' ol" our refjion 

 hasod larjjely on tlie «'olloctions of the U. S. National Museum. Mr. 

 .leionie M«Neill published (1887) two pa])ers in the tenth vohinie of the 

 Proceedinjjfs of the V. S. National Museum; in these eijjhteeu new s])e- 

 (!ies were described. A third paper jmblished in LSSS adch'd another 

 species, Pohfdfstmis butlcri, to the Indiana fauna. This brinj^s the 

 summary of literature to tlu' time when Mr. Ilollman first eonimeneed 

 his ])ublieations. It will be seen that the work on the myriapoda of 

 the United States consists larj^ely of fraj;inentary papers scattered 

 amon^ the scientific periodical literature of several lan<»na<ies. Only 

 one work — that of Dr. IT. C. Wood — made any atttimpts at complete- 

 ness, and that had been i)ubli.she(l almost a quarter of a century. The 

 time was rii)e for sonu' 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 couhl be found. Into this work 

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

 numerous papers that in vso 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 Academi/, one in the 

 A7nerican Nafurnlist, and four in Entomohujiva Amerieana. 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 aLd 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 brietly consi«lered. 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 Ileport on the insects of New York, Fitch describes the 

 ravages of Folydesmits comphmatits j in cabbagt, causing the so-called 

 "club foot." Walsh, in the Practical Entomolof/ist for 180(5, describes 

 Jidus multistriatus, which he afterwards identified as J. cerulcoeinctus 

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

 molof/ixt for 1809, he mentions two forms, a Jnlus and a Polydesmm^ as 

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



"Adding to these the species described iu the Proceedin<j;s of the U. S. National 

 Museum iind the extent of Mr. Bolhiian's work on the Myriapoda is apparent; the 

 totals will then he 3 genera and O;} species.
