REVISIOlSr OF NEARCTIC TERMITES. 35 



In some specimens the jaws are nearly as long as width of the head, 

 and more sharply pointed, the head proportionally a little longer, 

 the pronotum rather more narrowed behind, otherwise about the 

 same. 



It was described from Porto Rico and " Kalif ornien " (San Fran- 

 cisco) ; no other specimens from California have come to hand, and 

 it is probable that there was a mistake in the label, or it was intended 

 for Lower California. 



Occurs in Porto Rico, Kingston, Jamaica, and southern Florida, 

 both on the mainland and offshore keys or reefs. Adam Key (coral 

 reef). Paradise Key (Lower Everglades), Cocoanut Grove, Miami 

 Beach, all in Dade County. (Fig. 21). 



Genus CRYPTOTERMES Banks. 



Winged. — Very similar to Kalotennes, but the wing has the median 

 vein bent up to unite with the radial sector beyond middle of wing; 

 in some forms the median is almost obsolete and the cubitus is bent 

 up and almost united to the radial sector near tip of wing. 



Soldier. — The head is but little longer than broad, but extremely 

 high or thick, the front part as high as elsewhere, and with a great 

 cavity in the front. The mandibles are bent near middle and each 

 armed with a tooth beyond middle in a like manner ; tibia with three 

 apical spines; cerci indistinct; femora not enlarged. 



KEY TO SPECIES. 



Winged. 



1. Head pale; median vein bent up toward radial sector cavifrons. 



Head dark; median vein faint or absent, cubitus bent up toward radial sector.

CRYPTOTERMES CAVIFRONS Banks. 



Winged. — Dull pale castaneous ; antennae and legs very pale ; wings 

 hyaline, costal veins castaneous ; tips of mandibles black. Head a 

 little longer than broad; slightly narrowed behind; labrum large, 

 broadly rounded on tip; eyes circular, less than diameter from lower 

 margin of head, about one .and a half their diameter from hind mar- 

 gin; ocelli large, subtriangular; adjoining eyes above, their inner ends 

 almost pointed; antennae much longer than head, 15-jointed; third 

 joint not different from second or fourth ; pronotum much less than 

 twice as broad as long, about as broad as the head, broadest in middle, 

 rather narrowed in front; front margin nearly straight across, barely 

 concave ; hind border also nearly straight, lateral margins with strong 

 haii-s. Wing scale about the length of the pronotum. (PL 3, fig. 2.) 

 Wings rather long, the abdomen reaching only about one-half way 

 out; radial sector with about three branches to the costa; other vena- 

 tion indistinct ; median vein meets radial sector at about origin of
