Type. — Described from a series of winged adults collected at the 

 type locality by L. Conradt (No. 5), Hopk. U. S. No. 16533; winged 

 adults have also been collected at Tacubaya, Mexico.

KALOTERMES TUBERCULIFRONS. new species. 



Soldier (pi. 1, fig- 1). — Head castaneous, light yellow-brown 

 posteriorly and darker — almost red-brown — on frontal slope, which 

 is somewhat similar to the front of soldiers in Holmgren's subgenus 

 Glyptotermes, that is, obliquely sloping, not being nearly vertical 

 or sharply delimited as in the subgenus Lohitermes Holmgren. 

 Nevertheless, this species {K. tubercuUjrons) would probably be 

 placed in the subgenus Procryptotermes'' Holmgren, although the 

 front of the head is not quite vertical. Front of head greatly de- 

 pressed in center (not entire front), dark in depression. Head 

 slightly broader in front, sides slightly concave. Eye spot large, 

 pale except for dark rim, oblique, separated from the antennal 

 socket by a distance equal to its short diameter. Large tubercle 

 over each antennal socket. The long diameter of the tubercle is 

 parallel to the rim of the antennal socket. Head with short hairs. 



Mandibles black — lighter at base— shorter than width of head, 

 broad and stout at base, slender and incurved at apex, but outer rims 

 of mandibles not curved inwards as in K. huhhardl Banks; left 

 mandible with two obliquely projecting pointed marginal teeth, not 

 as near apex as in K. huhhardl Banks, broad tooth near base; right 

 mandible with pointed marginal tooth near base, at basal third. 

 Labrum yellow-brown, broader than long, with long hairs at tip, 

 where broadly rounded. 



Antennae pale, broken, pubescent; first, second, and third segments 

 dark-castaneous, third segment greatly elongate, slender, clavate, 

 longer than first and second segments together ; fourth segment pale 

 brown, ringlike, shorter than second segment. 



Gula slender, hardly one third as broad in middle as at tip. 



Bronotum light-castaneous, anterior margin black, apparently not 

 as broad as head, twice as broad as long; anterior margin deeply 

 roundedly emarginate and irregularly serrate (not dentate as in 

 huhhardi). Lateral margins gradually slope posteriorly (nearly 

 parallel) ; posterior margin almost straight. 



Meso- and meta-notum and abdomen yellow-brown ; abdomen with 

 short pubescence. 



' The subgenus Procryptotermes includes species from Madagascar. However, accord- 

 ing to Holmgren, the winged adult is as in the genus Cryptoterm.es Banks, which is not 

 true of North American specie.s,, which would fall into -tins subgenus if based on char- 

 acters in the soldier caste aione; these characters are an enlarged and modifled third 

 segment of the antenna and the nearly vortical front of the head.
