Worker. Length 6.5 mm. 



Related to L. emerr/i Forel. Head slightly longer than broad, occipital 

 angles broadly rounded, border straight. Frontal carinae short, their lobes 

 small. Clypeus strongly and acutely carinate at middle, projecting in front, 

 the projected portion twice as broad as long with a feebly biconvex border. 



Mandibles shorter than sides of head. 

 Antennal scapes slightly surpassing the 

 occipital corners; funicular joints one 

 and three subequal in length and shorter 

 than the second; joints four to ten sub- 

 equal; terminal joint a little less than 

 twice the length of penultimate. Pro- 

 thorax broader than long; rounded in 

 front and at sides; in profile only slightly 

 convex above. Mesothorax a little 

 broader than long, the sides and front 

 rounded. Mesoepinotal impression pro- 

 found. Epinotum convex, broadest be- 

 hind; in profile the basal portion is one 

 and two third times as long as the de- 

 clivity. Petiole very slightly longer than 

 broad; in profile, slightly higher than 

 long, rounded in front and at top; pos- 

 terior surface flat. Gaster slender; con- 

 striction between first and second gastric segments not strong. 



Shining. Front rugulosely punctate, vertex at middle with short trans- 

 verse and reticulate carinulae; remainder of head, thorax, epinotum (except 

 declivity), and petiole W'ith coarse foveolate punctures which are more dense 

 and confluent on the epinotum than elsewhere. Epinotal declivity trans- 

 versely striate. Gaster more shallowly punctate. Mandibles and antennae 

 shining, punctate. 



Pilosity long and fine, abundant; erect on head and body, semierect on 

 antennae. The femora and tibiae have, in addition to semierect pile, finer and
