anterior portion of the head, from the anterior extremity of the frontal 

 carinae forwards, subvertically truncate. Median area of the clypeus 

 twice as long as wide, its anterior margin convex, surrounded by a 

 deep groove ; the lateral pieces of the clypeus triangular and very 

 small. Frontal carinae widely divergent behind, the distance between 

 them behind being one-third greater than their length, their posterior 

 ends are nearer to the sides of the head than they are to each other. 

 The scapes extend beyond the hind margin by about the length of 

 the 1st and 2nd joints of the flagellum. Eyes large, flat, placed at 

 the posterior third of the sides. Dorsum of thorax feebly convex 

 longitudinally, a little more convex transversely. Pronotum one- 

 third wider than long. Mesonotum as long as wide or a little longer, 

 much narrower behind than in front. A trace of the metanotum 

 present. Sides of the epinotum ^ vertical, the dorsum as wide at the 

 apex as at the base, twice as long as wide,* joining the vertical and 

 slightly longer declivity by a very short curve. Scale thin, feebly 

 convex in front, flat behind, the dorsal edge trenchant and feebly 

 emarginate in the middle. Thorax highest at the apex of the dorsum 

 of the epinotum. Tibiae cylindrical, not setose below. 



£ minor, 6-6*5 mm. Brown, the pronotum and anterior half of the 

 head usually more yellowish brown. Very finely and superficially 

 reticulate-rugulose on the head and thorax, the abdomen transversely 

 rugulose. The whole body fairly shining. Pilosity exceedingly 

 sparse, the pubescence like that of the 2J.. Head of the normal form, 

 not subtruncate in front. The form of the body more or less like 

 that of the £ minor of the Myrmoturba group. Head oval, half as long 

 again as wide, a little wider behind the eyes than in front of them, 

 the eyes large, convex and placed behind the middle. Mandibles 

 sparsely punctured, narrower and longer than in the 2j_, the external 

 margin only slightly convex. Frontal carinae much less divergent 

 than in the %. Clypeus convex transversely, hardly carinate, of the 

 usual shape of this caste. The scapes extend bej^ond the hind margin 

 by half their length. Thorax strongly compressed posteriorly, its 

 posterior half very convex lengthwise, highest at the base of the 

 epinotum, L. = 2| H. The dorsum of the epinotum three-fifths longer 

 than the subvertical declivity, their junction forming a narrowly 

 rounded angle. Scale oval, the upper margin trenchant and entire. 

 Otherwise like the 2J..

 a slip of the pen.
