NOTES ON INDIANA HALTICINI WITH CHAR- 

 ACTERIZATION OF A NEW GENUS AND DE- 

 SCRIPTIONS OF NEW SPECIES. 



By W. S. Blatchley, 

 Indianapolis, Ind. 



During the ten years that have intervened since ni}' " Coleoptera 

 of Indiana '" was issued, a number of interesting HaUicini have been 

 added to the known fauna of the State. Some of these are evi- 

 dently new to science and one of them belongs to none of the genera 

 included by Dr. Horn in his " Synopsis of the Halticini of Boreal 

 America. "1 I have therefore, in this paper, founded for it a new 

 genus, have described eight species and named one variety believed 

 to be new, and have added notes on a number of others. The order 

 followed is that of the genera and species of the Tribe in the 

 Coleoptera of Indiana. My thanks are due to H. C. Fall, of Tyngs- 

 boro, Mass., for comparisons made and suggestions given, examples 

 of all the supposedly new species having been submitted to him. 



Disonycha pennsylvanica parva new variety. 



This is the small form occurring about a cypress swamp in Knox 

 County, and characterized but not named by me on page Ii88 of the 

 " Coleoptera." Since it differs from pciiiisylz'aiiica in having the 

 elytra non-alutaceous, almost wholly without punctures and always 

 with a double fold or sulcus along the median black stripe, it may in 

 time be recognized as a valid species, since no intermediate forms 

 have been seen. I found it in numbers about a similar swamp at 

 Sanford, Fla., in April, 191 3. and it is probably the form mentioned
