REVISION OF NEARCTIC TERMITES. 131 



size of occidentis, they are more prominent. The wing venation is 

 evident on the wing buds. Holmgren (1911) established a new genus 

 (Pterotermes) for this termite. 



K. occidentis occurs in Lower California and Arizona. Mr. Banks 

 is not certain whether the winged adults collected in Arizona are of 

 this species, although they agree in size. If they are not occidentis, 

 then the}^ represent a new species. 



This termite swarms in Arizona in August: Coyote Mountains, 

 August 4 to 7, and Baboquivari Mountains, August 7 to 9, 1917, Lutz 

 and Rehn. 



George Hofer found young parent adults in an mcipient colony in 

 the sap wood of a dead Palo Verde tree in Sabino Canyon, Santa Cata- 

 lina Mountains, Arizona, on January 7, 1917. Only six young were 

 in this colony. 



Some of the nymphs of the reproductive forms have the (short) 

 wing pads mutilated; that is, probably partially bitten (at the ends). 



KALOTERMES MARGINIPENNIS Latreille. 



For taxonomy see pp. 20-22. 



Latreille (1833) described this termite (Termes marginipenne) from 

 types collected in Mexico. It is a native of Mexico and Central 

 America. In the United States K. marginipennis occurs in south- 

 western Texas, southern Georgia, and probably northern Florida. 



This termite occurs as far north as the vicinity of Savannah, Georgia. 

 It is injurious to the wood of telephone and telegraph poles in Georgia 

 and Texas, working not only in the wood near the base, but also in 

 the dry, hard wood high up in the poles. It is also injurious to the 

 woodwork of buildings. 



In the forest, colonies occur in dead trees, logs, and dead branches. 

 This species is common in Texas, from Brownsville, Los Borregos, 

 Las Palmas, Point Isabel, in Cameron County; San Diego, Duval 

 County; Corpus Christi, Nueces County; Victoria, Victoria County; 

 San Antonio, Bexar County; Brazos County; Uvalde, Uvalde 

 County. In Georgia it occurs at Albany, Dougherty County, and in 

 the vicinity of Savannah in Chatham County — Bloomingdale and 

 Pooler. In Florida, Hubbard collected this termite in a mangrove 

 stump on Mangrove Island, Indian River, April 6, 1880. 



SWARMING. 



K. marginipennis swarms at night. E. A. Schwarz states (1896) 

 that ''A few winged specimens of this common Mexican species were 

 attracted by light in houses in San Diego (Texas) after a rain on 

 May 21, and some other individuals deprived of wings were found 

 running about during subsequent days." Winged adults have been
