ART. 6. iq-EW SPECIES OF TERMITES SNYDER. 17 



Labrum yellow, longer than broad, broadest near middle, somewhat 

 tongue-shaped, narrowed toward apex where somewhat pointed, apex 

 with bristles. 



Mandibles castaneoiis-brown with reddish tinge, elongate, slender, 

 curved inward near tip, with 4 rudimentary teeth at base of left 

 mandible. 



Gula at narrowest point (near middle) less than one-half the width 

 at the front (near apex). 



Pronotum white with a tinge of yellow, subcordate, not as broad as 

 head, with pubescence. 



Legs white with a tinge of yellow. 



Abdomen white with a tinge of yellow, pubescent. 



Measurements. — Length of entire soldier, 4.7 mm.; length of head 

 with mandibles, 2.25-2.30 mm.; length of head without mandibles, 

 L4 mm.; length of left mandible, 1 mm.; length of pronotum, 0.4 

 mm.; length of hind tibia, 0.62 mm.; width of head, 0.85-0.90 mm.; 

 width of pronotum, 0.7 mm. 



Described from a series of soldiers found with the typical winged 

 adults. 



Close to L. tenuis Hagen but paler, with more yellow and less 

 brown color than in tenuis; the post-clypeus is not strongly bilobed 

 and the wing has the median vein located differently than in tenuis. 

 The most strikingly distinctive character is the convex posterior 

 margin of both the meso- and metanotum — hence the specific name; 

 also the fact that the wing scale covers the mesonotum — not the 

 case in tenuis. The soldier is smaller, more slender, and has but few 

 hairs on the head — a distinctive specific character; in tenuis the soldier 

 has 17 segments to the antenna and the mandibles have the minute 

 teeth or denticulations at the base of the left mandible larger and 

 more prominent. 



Type locality. — Colon, Panama. 



Described from a series of winged and dealated adults collected at 

 the type locality by engineers of the Western Electric Co., in wood- 

 work of cable oflice, "Cable, 4/ll/'14," Hopk. U. S. No. 12817a; 

 workers, soldiers, and nymphs also found with these adults.

LEUCOTERMES CARDINI. new species. 



Winged adult. — Head pale yellow-brown, darker between the eyes, 

 paler posteriorly; sub elliptical, widest at the eyes, rounded poste- 

 riorly; with dense short and longer hairs. Fontanelle a pale, slightly 

 raised, round spot on a line just back of the eyes. 



Antennae light yellow, with 17 segments, pubescent; segments 

 become wider toward the apex, vary in size and shape; first segment 

 elongate, cylindrical; second shorter than first, third ringlike, about
