months collecting in the various islands till June 23, 1899, and 

 then sailed to Cocos Island where they remained five days, June 

 29th to July 3d. Thence they sailed homeward and after 

 touching at Clarion Island, in the Revillagigedo group, on 

 August 2, they arrived in San Francisco on August 15, 1899. 

 Their collections include mammals, birds, reptiles, fishes, 

 insects, mollusks, arachnida, Crustacea, echinoderms and plants 

 in all of which departments they strove to make full collections. 

 Most of the material will be permanently retained in Stanford 

 University. The spiders and insects have been sent to Dr. L. 



0. Howard, in Washington, for distribution to and study by the 

 government specialists in the various orders. All the collec- 

 tions are to be studied and reported upon by specialists and the 

 results published in these proceedings under the general heading 

 Papers from the Hopkins Stanford Galapagos Expedition^

In the collection of hemipterous insects brought back from 

 the Galapagos Islands by Mr. R. E. Snodgrass, in 1899, I find 

 two species new to science. These are described in this paper. 

 Several others, though previously known, had not been previously 

 reported from or collected in the Galapagos.
