The Annual report upon the Geog. Surv. west of the 100th 

 Meridian ... by Lieut. Wheeler, contains the following papers : 

 by H. Ulke (1875, p. 809-827) list of 389 species collected 

 in several western states and territories, with localities ; by Dr. 

 LeConte (1876, p. 296-300) list of 75 species from southern 

 California and 224 species from northern Colorado and northern 

 New Mexico. 



It may not be amiss also to note the publication of such lists 

 of Coleoptera for sale as have indications of the localities ; 

 these are the earlier and smaller lists published by the Philadel- 

 phia Agency in 1874, and G. W. Belfrage's list of 471 Texan 

 species in Psyche Advertiser for December 1876. 



The preceding lists, from their extent or the interest attached 

 to the localities, seemed to demand special notice, and the fore- 

 going sketch shows that much progress has been made in col- 

 lecting data for solving the problem of the present distribution 

 of North American Coleoptera. The published lists, however, 

 are far from representing the whole progress in that direction, 

 and I will briefly notice some of the principal collections known 

 to me which are capable of adding materially to our stock of 

 knowledge, and which I trust will be used for that purpose in 

 the near future. 



Mr. Henry Ulke has collected for many years in the vicinity 

 of Washington, D. C, and can give a nearly complete catalogue 

 of the Coleoptera of that region. 



Mr. Samuel Auxer has made a collection in the vicinity of 

 Lancaster, Pa., which will give a good idea of the fauna of that 

 section. 



Good materials for a representation of the fauna of Texas 

 exist in the collections of Messrs. Belfrage, Boll, and others. 



The extensive collections made by Mr. G. R. Crotch, in 

 California and British Columbia, would have contributed greatly 

 to our knowledge of the distribution of the species of the Pa- 

 cific coast, as all the specimens had the localities carefully 

 marked, if only a set had been kept together for investigation. 



Mr. A. S. Fuller has accumulated, during the past few years, 

 an immense collection from all parts of the country, which will 

 doubtless furnish much information in this reaard.
