TERMOPSIS LATICEPS Banks. 



For taxonomy see pp. 15-16. 



This species was described by Banks (1908), the type specimens 

 being from Florence and Douglas, Arizona. It occurs in Arizona 

 and New Mexico. 



Townsend (1893) published a short paper, entitled: A Note on 

 Termopsis angusticollis Hagen, giving descriptions, measurements 

 of the soldiers and nymphs, and biological notes on a large termite 

 found on February 11, 1893, in galleries in dead or nearly dead Cot- 

 tonwood trees (Populus fremontii), near Las Cruces, Dona Ana 

 County, New Mexico. The specimens had been determined by C. V. 

 Riley as Termopsis angusticollis Hagen, but according to Townsend's 

 measurements undoubtedly are T. laticeps Banks. 



Townsend writes: 



A row of large cottonwoods along an a,cequia showed an unhealthy condition and was 

 cut down. Most of these were found to be mined by the termites. They seemed to 

 prefer the more moist parts of the tree, either live wood or wood moistened by the 

 proximity of the water in the acequia. 



H. G. Hubbard, on May 22, 1897, collected nymphs of this termite 

 in the Galiuro Mountains, Graham County, Arizona, from "hollow 

 in base of a willow tree." 



M. Chrisman, on July 3, 1914, collected soldiers, nymphs, and im- 

 mature winged sexual adults of 'T. laticeps Banks in Edgar Canyon, 



1 These spiral markings may be only outlines of the egg follicle cells since fresh eggs do not have thes e 

 markings.
