420 REPORT OF STATE GEOLOGIST. 



AVhile the individuals of Nemohius are so plentiful, their size is so 

 small that they have received but little attention from the average 

 collector. Moreover, so similar in general appearance are they that 

 very close observation by the student is necessary to separate the 

 species one from another. As a consequence but 15 have hitherto 

 been described from the whole United States. Up to May, 1900, 

 when the writer described three new species from Indiana* but 

 three had been accredited to the States north of Florida and east of 

 the Rocky Mountains. McNeill listed but one from Illinois. Bruner 

 mentions three, two without names, from Nebraska, while Scudder, 

 in his most recent paper on the group, accredits three, viz.: N. 

 fasciatus, N. cubensis and N. carolinus to the central and eastern 

 States. 



Within the past ten years many specimens have been collected in 

 different parts of Indiana. A careful study of these reveals the pres- 

 ence of at least eight species. There is little doubt but that the right 

 kind of investigation will show the presence of as many or more in 

 almost any State east of the Rocky Mountains. Those known to 

 occur in Indiana may be separated by the following key:
