BIOLOGY IN THE ROCKY MOUNTAINS. 167 



Orthoptera of Colorado. As might be supposed, the entomological 

 collections and library are very good, although the latter does not 

 contain everything I expected to see. Professor Gillette is at present 

 assisted by Mr. S. Arthur Johnson, a relative of the well-known curator 

 of the Boston Society of Natural History. Mr. Johnson is doing very 

 nice work on the Hymenoptera, especially on their nesting habits and 

 parasites. He has discovered, for example, the hitherto unknown 

 nest of Entechnia, and has definitely proved the association of 

 Triepeolus with Melissodes. Also with Professor Gillette is Mr. Chas. 

 Jones, a young entomologist who will be heard of in the future. Last 

 summer he worked in a mine at Silverton, Colorado, and spent his 

 leisure moments making by far the largest and best collection yet made 

 of the insects of the Arctic- Alpine zone in the Eocky Mountains. In 

 the Department of Botany and Horticulture at the Agricultural Col- 

 lege, Professor Paddock is properly a horticulturist; but his assistant, 

 Mr. F. M. Eolfs, a brother of Professor Eolfs, of Florida, is doing some 

 very interesting work on parasitic fungi. The herbarium of the college 

 gave me much surprise and pleasure. The last time I saw it, several 

 years ago, it was in such a condition as to be of little use for critical 

 work. Now, the Colorado material in it has all been gone over by 

 Dr. P. A. Eydberg, of New York, who has in press a list of the flora 

 of Colorado, i. e., of the flowering plants thereof. The greater part of 

 the named material has been returned to the college, and I was nat- 

 urally very much interested in the determinations. Although, as I 

 learned from Professor Paddock, the college herbarium contains only 

 about half as many Colorado plants as they have in the New York 

 Botanical Garden, it is by far the best and most useful public herbarium 

 in the state. I say public herbarium because Mr. Geo. Osterhout, of 

 New Windsor, Colo., has long studied the native flora, and is said to 

 have a very fine collection. He has described quite a number of new 

 Colorado plants. At the Normal School, at Greeley, they do not pre- 

 tend to do much research, but Professor Beardsley has made some 

 studies of the minute fresh-water Crustacea, and of the Protozoa, de- 

 scribing some new species. He has also made a collection of Colorado 

 reptiles and amphibia, and will, I believe, publish a list of them. The 

 library of the Normal School is very well arranged, and contains some 

 good zoological books I did not expect to see. 



In Denver, the State Historical and Natural History Society has a 

 collection, poorly housed in the lowest floor of the capitol building. 

 Mr. Ellsworth Bethel, of the Denver West Side High School, has long 

 studied the fungi and flowering plants of Colorado, and has a large 

 collection. He has discovered very many new species, especially among 

 the fungi, but his duties leave him little time for research. The East 

 Side High School in Denver has a herbarium, presented by Miss Alice
