Ninth Annual Meeting. 15 



The water also holds in solution a small amount of the hydrocarbon gas ( together 

 with carbonic oxide, oxygen and nitrog^i ), but this seems not to decompose at all during 

 evaporation, as it does not contaminate the solid residue. 



The temperature of the water as it issues from the well is constant throughout the 

 year, and is about 61° Fah. 



LIST (W COLEOPTERA 



CoUected in Colorado in June, July and August, 1876, by the Kansas University Scientific 



Expedition. 



BY PKOF. F. H. SNOW. 



Five members of the class of 1876 of the University of Kansas, after commencement, 

 organized a scientific expedition for explorations in Colorado, and invited me to accom- 

 pany them. The names of the students were as follows : George F. Gaumer, Charles W. 

 Smith, Elmer B. Tucker, Miss May Eichardson and Miss Lizzie Williams. My wife and 

 son were also members of the party. Large collections were made of insects, plants, 

 birds, mammals and reptiles, the chief attention being devoted to the first two of these 

 departments. A few minerals were also collected. Three weeks were spent at Colorado 

 Springs, from which point excursions were made to the Plains on the east, to the summit 

 of Pike's Peak, Chiann Canon, and various other localities. Three weeks were devoted 

 to an expedition to the South Park by way of the Ute Pass. During the first week in 

 August the students returned home, but the rest of the party remained in camp in Engel- 

 raann's Canon, along the trail to Pike's Peak, until September 1st, making large collec- 

 tions of insects. 



Of the material thus accumulated, I have as yet had time to "work up" only a single 

 order of insects, the Coleoptera. In this order three hundred and four species and twelve 

 varieties were collected ; among them twelve new species, and one of Thomas Say'g 

 "long-lost" species {Dictyoptera sanguinipennis) . The list includes a few species taken 

 by Mr. Edwin A. Popenoe, of, Topeka, who spent two weeks in Colorado, and was with 

 us for a single day at Colorado Springs. 



For the determination of a large proportion of the species not previously in my col- 

 lection, I am indebted to Dr. .John L. LeConte, of Philadelphia, who Avill describe the 

 new species discovered by our party. The number prefixed to the names are those of 

 Crotch's "check-list." Instead of using the word "rare" to denote infrequent occurrence 

 of a species, I have preferred to mention the exact number of specimens in each case 

 obtained. 



LIST. 



CicindeliUjK. I long suspected, that they should not be considered 



1'. Amblychilac)'lindriformis,5ay. Asinglespecl- | distinct species, 

 men was found dead in a spider's web, in Webster I 25. Cicindela venusta, Lee. A single specimen 



Park, by Mr. Popenoe. The rarity and value of this 

 insect taay be inferred from the fact that |12 are 

 asked for a single specimen by Eastern dealers. 



12. Cicindela longilabris, Say var. South Park, 

 sandy plains, common; diflfers somewhat from the 

 type-form. 



22. Cicindela purpurea, 0/n'. var. Audubonii, Z,ec 

 South Park ; same localities as the preceding. 



23. Cicindela cimarrona, Lee. South Park, with 

 the preceding. A large series of the last two forms 



only, on the plains near Colorado Springs. 



27. Cicindela fulgida. Say. Banks of the Platte, 

 in South Park; only five specimens. 



28. Cicindela tranfjuebarica, lib. var. Two speci- 

 mens. 



30. Cicindela 12-guttata, Z>e;. Abundant at Mani- 

 tou and vicinity. 



306. Cicindela guttifera, Lee. Same localities as 

 the preceding. 



37. Cicindela cinctipennis, Lee. Only five speci- 



was taken, convincing Dr. LeConte of what he had ■ mens; locality not noted
