punctured than in Empedocles, slightly dull near their bases. Dorsum 

 of epinotum one-third longer than the vertical declivity, rounded 

 transversely but nevertheless distinct from the sides, not subcristate 

 as in Empedocles and Thales. Scale of petiole one-third higher than 

 the petiole is long, the anterior face moderately convex, the posterior 

 face flat, the dorsal edge convex from side to side. Tibiae compressed 

 and setose below. 



y minor, 6*5-8 mm. Head one-fourth to one-third longer than 

 wide, the sides convex, the posterior margin straight or feebly con- 

 cave in the larger examples, not wider behind than in front. Legs 

 with an oblique and longer pilosity than in the Q|. Dorsum of 

 epinotum at least twice as long as the very oblique declivity, joining 

 the latter in a low curve, narrower above than in the Qj., but wider 

 than in the ^ minor of Empedocles. 



"9, 13 mm. Head 3-8 >< 3 mm.; scape 2-5, posterior femur 3-8, 

 tibia 3"2 mm. Relatively small, colour and sculpture as in the g. 

 Head subrectangular, with rounded angles, barely a little narrower 

 in front than behind. The scale is higher than in the Q)., its ante- 

 rior face less convex, the dorsal edge straight or slightly impressed 

 in the middle. Wings yellowish, the marginal and submarginal 

 nervures brown, the other nervures testaceous."

Qj.. Mandibles as Thales, but shining, a little less punctured, 

 barely or not at all reticulate. Lobe of the clypeus a little longer; 

 frontal carinae less divergent. Eyes placed behind the middle. 

 Sides of the head a little more convex, the head a little narrower 

 at the occiput. Otherwise the head is like that of Thales, including 

 the length of the scapes. Thorax like that of Thales, but with the 

 meso-epinotal suture very distinct, and the dorsum of the epinotum 

 hardly longer than the declivity. Scale fairly thin and high, the 

 dorsal edge obtuse. Tibiae cylindrical, not compressed, sometimes 

 with one bristle near the base of the internal margin. Legs short. 

 Densely and finely reticulate-punctate and dull. Abdomen and scale 

 finely shagreened or rugulose transversely, the scale subopaque, the 

 abdomen shining. Legs shining and feebly rugulose. There is a 

 fine and distinct puncturation on the abdomen, indistinct elsewhere.
