and never in the bright sunshine. In June, 1861, in Llano County, I saw them 

 carrjdng home dry segments of post-oak leaves of the preceding year's growth. Here 

 again the nasuti worked in common with the rest of the tribe. They must have 

 preferred these dry leaves, because green leaves and grass were abundant on every 

 side. They are all quite active, moving faster than any species of termites which 

 I have seen. 



C. cinereus occurs from central Texas to Beeville, not far from the 

 Mexican border, west to New Braunfels (Comal County) and Uvalde 

 and Devils River (Valverde County). It swarms at night. 



Schaupp collected this termite as early as 1889 (December ?) at 

 Tiger Mills in Burnett County, Texas. 



The late F. M. Webster on March 23, 1891, found a colony of this 

 termite in the nest of a beaver at Devils River, west of Del Rio, on 

 the Mexican border on the Rio Grande, Texas. A young true or first 

 form queen was present. (Fig. 58, 1.) This was on the famous 

 expedition after beaver parasites along the Pedernales River (Blanco 

 County). E. A. Schwarz found colonies at Beeville and San Diego 

 in 1895. On November 8 a colony was found under cow dung at 

 Beeville; on May 31 workers and nasuti were found on the underside 

 of fungus at San Diego; and on December 3 another colony under a 

 stone at San Diego. R. A. Cushman found this termite at Lampasas 

 on April 14, 1909. His notes are: 



Under a fiat stone found a colony of peculiar termites, including the queen, workers, 

 Boldiers, nymphs, and eggs. The workers are Collembola-like in form, having large, 

 rounded heads and stout abdomens. The soldiers are much smaller than the workers; 

 have black or dark brown shining heads prolonged into a pointed beak. While the 

 workers are not more than three-sixteenths inch long, the queen, though not distended, 

 is at least one-half inch long and stout, with the thorax nearly as wide as the abdomen; 

 in the worker the thorax is very narrow. (The queen was of the first form; a j^oung 

 queen.) 



When I turned the stone over the workers began running around very actively and 

 carrjdng the eggs and nymphs into the subterranean burrows. Under the same stone 

 was a colony of ants of the genus Pheidole and another colony of termites of a different 

 species. None of the latter were collected. 



This queen was 11 mm. in length, with abdomen slightly distended. 



Near Uvalde, Texas, the writer found colonies of C. cinereus early 

 in May, 1917. On May 4, at Laguna, Texas, 20 miles north of 

 Uvalde, workers and nasuti were again found under cow chips 

 associated with Amiiermes iuoiformans Buckley, near an irrigation 

 ditch. Earthen galleries were in the dung and in the soil to the 

 depth of several inches. The nasuti are very peculiar looking and 

 of great interest to one seeing them for the first time. They are 

 smaller than the workers. On May 5, north of Uvalde, in a moist 

 pasture (green grass) near irrigation, other colonies were found. 

 The cow chips were moist and fairly fresh. The termites (workers 

 and nasuti) were in the soil and in earthern galleries on the bottoms 

 of the cow chips. These tubes lead from the ground to the chips.
