mandibles black on tips. Eyes nearly round, almost diameter from

 the second. Pronotum broader than head, plainly less than twice as 

 broad as long, broadest in the middle, not rounded much on the pos-

 Wings pale, costal veins dark, radial sector with four to six branches 

 to costa; the first few are very long, median vein i-uns nearer to 

 radial sector than to cubitus. Wing scale a httle longer than the 

 pronotum. (PI. 2, fig. 2.) Head, pronotum, and abdomen with long 

 erect hairs on the abdomen in 

 rows near hind margin of each seg- 

 ment. 



Length to tip of wing, 15 to 16 

 mm.; body, 8 to 9 mm. (Fig. 12.) 



Soldier. — Head castaneous, dark- 

 er in front; mandibles black; legs 

 pale, anterior tibiae usually darker; 

 thorax castaneous above; abdomen 

 paler. Head, from barely longer 

 than broad to fully one and a half 

 times as long as broad; in the long- 

 headed f orrfLS the sides are parallel ; 

 in the. short-headed forms the sides 

 are more convex; labrum tiimcate; 

 eyes distinct, behind the antennae; 

 antennae fully as long as the man- 

 dibles, about 16-jointed, the third 

 joint full}^ as long as the fourth 

 a.nd fifth togethe]', strongly chitin-

 the points of the mandibles are more slen.der than in others; the 

 last joint of the maxillary palpi much longer than the preceding, 

 the gula is about half as wide in middle as in front ; the pronotum 

 fits closely over the base of the head; it is about twice as broad as 

 long ; the anterior margin is strongly, angularly indented in the mid- 

 dle, and the anterior sides convexly oblique to the indentation; the 

 outer sides nearly parallel, the hind border slightly concave. Femora 

 greatty swollen ; the hind tibia with three stout spmes. Body and 

 legs vath numerous, short, simple, erect hairs. 



Length, 7 to 10 mm. (Figs. 10, 2, and 3.) 



Occurs in Cuba and southern Florida both on the offshore keys or
