tarsi and simple claws : middle tibiae without spurs, hind 

 tibiae with a single large feebly-pectinated spur. Body 

 opaque, sculptured; hairs absent; pubescence short, dense, 

 and silky. 



Female (dealated). Very similar to the worker and but 

 slightly larger. Ocelli present, but small; eyes somewhat 

 larger than in the worker. Thorax with distinct pronotal, 

 mesonotal, scutellar, metanotal, and tegular sclerites, and 

 with stumps of the lost wings. 



Prodi scothyrea velutina, sp. nov. 



Worker. Length, about 2 mm. 



Head subrectangular, a little longer than broad, 

 decidely narrower in front than behind, very convex above, 

 with straight posterior and rather convex lateral borders and 

 rounded posterior corners. Gular surface rather convex, with 

 a prominent, ridge-shaped tubercle on each side. Clypeus 

 transversely and regularly convex, its anterior border straight 

 and distinctly crenulate, especially in the middle. Frontal 

 carinae extending back about two-thirds the length of the 

 head, dilated and horizontally flattened in the middle, the 

 space between them scarcely concave, rounded antero- 

 posteriorly and continuous with the regular convex surface 

 of the head. Antenna! scapes nearly two-thirds as long as the 

 head; scapes incrassated, especially at the apex, where they 

 are nearly one-fourth as broad as their length; first funicular 

 joint rather broad, subglobular, distinctly broader than long ; 

 joints 2-5 subequal, very transverse; 6-8 larger and propor- 

 tionately longer, terminal joint very large, glandiform, as 

 long as the remainder of the funiculus, about two and one- 

 half times as long as broad. Thorax narrower than the head, 

 seen from above trapezoidal, about one and two-fifths as long 

 as broad, and one and one-half times as broad through the 

 humeri as through the epinotum, sides slightly concave ; 

 humeri bluntly angular; in profile the thoracic dorsum is very 

 unevenly convex to the declivity of the epinotum, which is 

 abrupt, concave, and marginate on the sides. Each margin- 

 ation merges into a scarcely distinguishable tubercle above, 

 and the base and declivity are separated by a transverse 

 ridge. Petiole from above nearly twice as broad as long, 

 broader behind than in front, with, straight anterior and 

 lateral and feebly convex posterior borders ; in profile the 

 segment is less than twice as long as high, convex and 

 anteriorly sloping above and on the sides, its ventral surface 

 compressed and translucent anteriorly, but without a spine
