variation in size of these specimens (5 — 6 mm.) is so great as to suggest 

 that they may include several closely related species. 



Shna lacrimarutn, sp, nov. 



Worker (Fig. 13). Length about 3 mm. 



Head longer than broad, subrectangular, with rounded posterior 

 corners and eyes in front of the middle. Ocelli absent. Antennal 

 scapes curved; first funicular joint as long as the three preceding 

 joints together, joints 5 — 7 broader than long, joints 8 — 10 nearly as long 

 as broad. Pro- and mesonotum feebly convex, mesoepinotal constriction 



distinct. Epinotum short, 

 ^-^ as high as long, convex and 



rounded, without distinct 

 base and declivity. Petiole 

 and postpetiole each longer 

 than broad, with a short pe- 

 duncle and the node roun- 

 ded above and somewhat 

 abruptly truncated behind. 

 Gaster and legs of the usual 

 conformation. 



Surface of body smooth and shining, apparently with small, sparse, 

 piligerous punctures. 



Hairs sparse, erect, most noticeable on the clypeus, mandibles, 

 palpi and tip of gaster. 



Color deep reddish brown. 



Described from a single well-preserved specimen (X 2) in the 

 Klebs Coll. 



This species appears to be closely related to 8. angustata, but 

 I have described it as distinct, on account of its very small size, the 

 larger and more anteriorly placed eyes and the shortness of joints 

 2 — 5 of the funiculus. 



Among recent species which are closely related to 8. angustata, 

 simplex and lacrimarum may be mentioned the Indian 8. nigra Roger, 

 compressa Roger, allahorans Walker, difficilis Forel and hinghami 

 FoREL, the Australian 8. leviceps F. Smith and the Madagascarene 

 8. rakotonis Forel and 8. hysterica Forel.
