REVISION OF NEARCTIC TERMITES. 181 



jBgs. 1-5). They honeycomb dry cow chips and are numerous in 

 the chips and in the ground under them. 



The writer first observed this termite in the "prairie" 1 mile east 

 of Victoria on April 19, 1917, where it was common under and in 

 dry cow chips on the ground and in the ground. Manure is carried 

 down into chambers below ground. Soldiers were not common in 

 colonies. Some of the workers have the heads pigmented a yellowish- 

 brown color, with antennae brown; other workers of the same size 

 are without this pigmentation, merely different stages to maturity. 

 Two young reproductive females of the second form and eggs were 

 in the ground in a cell several inches deep in a colony, (Fig. 42, 3.) 

 Nymphs of the first form with long wing pads were also in this same 

 colony. The ground was very hard and the colony was dug out 

 with an axe. 



Anoplotermes fumosus Hagen was found for the first time by the 

 writer associated with A. tubiformans under and in cow chips. It 

 was noted after several days' search that there were no soldiers in 

 the colonies of Anoplotermes. 



In the vicinity of Bro^vnsville, Texas, A. tuhiformans was foimd to 

 be common under cow chips; Lloma Alto Lake, Las Palmas, etc. 

 (Apr. 22 to 25, 1917), also under dry dead cactus (prickly pear) 

 Opuntia on the groimd. Near Brownsville the smaller Amitermes 

 wheeleri Desneux was first found by the writer, associated with A. 

 tubiformans or Anoplotermes, in and under dry cow chips. 



Near San Antonio colonies were also common in pasture land, 

 April 26 to May 2. This species was also found by the writer at 

 Cotulla, Texas, on May 1 ; the soil in this vicinity was very dry and 

 deeply cracked by drought to the depth of 1 foot. Near Uvalde col- 

 onies were common and often very large, under cow chips; Chalk 

 Bluff, Laguna on the Nueces River, and at Uvalde in pastures along 

 the Leona River, and also on dry prairie land near Sansom. 



At El Paso, on the foothills near the city, A. tubiformans was foimd 

 on May 9 under cow chips and under the trunks of dead tree Yuccas 

 lying on the ground. 



In the vicinity of El Paso the vegetation on the bare rocky hillsides 

 consists of cacti and Agave, creosote bush (Govillea glutinosa), etc. 



At none of these localities in Texas at which the writer found this 

 termite in April and May did he observe its tube-forming habits, 

 which was doubtless due to the dry season. It was not until August 

 (Uvalde) and September (Victoria) that these tubes were observed 

 in 1917 by Messrs. Parman and Mitchell. 



SWARMING. 



A . tubifonnans swarms during the daytime. 



On July 5, 1916, D. C. Parman found this termite swarming at 

 Uvalde, Texas. The swarm occurred from 2 to 4 p. m. in large num-
