ART. 20, SOME NEW AMERICAN TERMITES SNYDER. 11 



Described from several winged and dealated adults, collected at 

 type locality by B. P. Clark in March, altitude 915 meters (3,000 

 feet); winged adults were also collected at Olaa; soldiers with 

 dealated adults were found on the mountains of Oahu, Honolulu, 

 Territory of Hawaii. 



Tijfe, tvlnged adult.— C^t. No. 24566, U.S.N.M. 



This species, the " mountain form " of " Calotermes " of Hawaii, 

 appears to be the " missing " or connecting link between the genera 

 Kalotermes Hagen and Neotermes Holmgren, hence the specific name 

 " connexus.''' The adult is clearly a N eotermes due to its character- 

 istic wing venation; the soldier, however, is a Kalotermes on account 

 of its swollen femora and enlarged third segment of the antenna 

 with the chitin deeply colored. Nevertheless, certain other known 

 species of Kalotermes have the soldier with the third segment of the 

 antennae simple, as K. simplicicornw Banks of Texas. 



Biological notes. — A " mountain form " — a native Hawaiian 

 termite — has long been known to exist.^ This termite was referred 

 to in literature as " Calotermes castaneus Burmeister." However, it 

 is the above described Neotermes connexus. It is a true forest insect, 

 confining itself entirely to the decaying or sometimes the living wood 

 of trees; this termite is found only in the mountain forests, but 

 occurs on all the islands. 



This species of Neotermes with Kalotermes immigra?is, formerly 

 considered to be marginipennis Latreille, are widespread in Hawaii. 

 While Kalotermes iminigrans is considered to have been introduced 

 to the islands (Bryan, 1915), N. connexus is endemic. 



Winged adults of A', connexus have been collected at Kauai, eleva- 

 tion 915 meters (3,000 feet), in March, B. P. Clark, and at Olaa, 

 elevation 800 meters (2,600 feet), in May, H. W. Henshaw. K. 

 immigrans swarms in June, " June 30, 1918 " (Fullaway).
