Melanostoma sulcifrons Stal, Enum. Hemipt. ii, 18, No. 2. 

 This odd little Pentatoinid has recently been found in very remotely 

 separated regions of the United States : first in Texas and Indian Ter- 

 ritory ; then in the valley of the Arkansas Eiver ; also in Georgia ; in 

 New Mexico ; and last summer, in July, I swept numerous specimens of 

 it from weeds in a pastnre-field sixteen miles southeast of Baltimore.

I obtained one specimen in the region of the Arkansas Eiver, near 

 Pueblo, by sweeping weeds with my net. It is common in certain sec- 

 tions of Texas, in Indian Territory, in Kansas, in Missouri, and in the 

 Atlantic region. 



Its nearest neighbor, the G, conspicillaris^ belongs to the more mount- 

 ainous regions, and occurs particularly on the west of the Eocky Mount- 

 ain Eanges.

It occurred to me while I was sweeping the weeds in the vicinity of 

 Oaiion City, Colo. ; also inhabits Texas and the Indian Territory, near 

 Cheyenne, and in many parts of the country east of the Eocky Moun- 

 tains from the Eed Eiver country to the vicinity of Quebec, and thence 

 along the Atlantic coast to Florida, and even into Cuba and Mexico.
