RETICULITERMES HUM ILIS Banks. 



For taxonomy see pp. 51-53. 



This termite has been found only in Arizona from localities near 

 the Mexican border to as far north as Flagstaff and Williams, in 

 Coconino County. It is a destructive wood borer and found by the 

 writer to honeycomb the hardest wood of oak stumps, "Palo Verde," 

 and the woody roots and stems of the bush cacti (Opuntiafulgida, 

 spinosier and versicolor). 



H. G. Hubbard found R. humilis in the Santa Rita Mountains as 

 long ago as May 20, 1898. The colony was under a stone in Madera 

 Canyon. To quote from Hubbard's note from his field diary: 



We ascended a ravine filled with majestic sycamore trees under which the ground 

 was wet with numerous springs, but entirely tramped by cattle and devoid of smaller 

 vegetation. * * * I found under a stone in a little dry mound in a wet spring 

 spot, on the mountain side, a colony of true Termes, among which, in a cell cavity 

 just beneath the stone was a single matured gravid female, or queen, which certainly 

 had been winged; took eggs, larvte, workers, and soldiers with the queen. This is 

 the first instance known of a true queen in the genus Termes. There were no sup- 

 plementary or nymphal queens in this colony and no male was found. I explored 

 the entire colony, which was not a large one. 



This is the first " true " queen (of the first form) found in the genus 

 Reticulitermes in the United States (Schwarz, 1901). The writer re- 

 ferred to this queen as R, ludfugus Rossi (Snyder, 1915). 



Prof. W. M. Wheeler found a first-form queen of humilis in Post 

 Canyon, Pinaleno Mountains, Arizona, at an elevation of 4,000 to 

 5,000 feet, on July 17, 1917. This queen was 13 mm. in length and 

 2 J mm. in width (measured after preservation in alcohol) and the 

 abdomen was distended with the segments markedly separated. 

 There are 12 segments to the antennae.
