other), to which the popular name of "Sugar-ant" has been applied. 

 It is very largely crepuscular and nocturnal in its habits, and is often 

 a nuisance in houses where it visits pantries, cupboards and other 

 places where sugary substances are kept. The nest is usually placed 

 under stones in the ground, and has the entrance surrounded by an 

 irregular and low crater. The § § media and minor may be seen 

 now and again at work round the entrance of the nest during the 

 day, but the QJ. Qj. are very rarely seen in the open before sunset. 



Up to a quite recent date, it was assumed that the type species 

 of maculatus of Fabricius was the form with pale tibiae, common in 

 Egypt. However, in a paper published a short time ago, Prof. Emery 

 pointed out that Fabricius described his species as having black tibae, 

 so that the Egyptian form must be treated as a variety of the type. 

 The latter is in the Banksian collection in the British Museum, and 

 has recently been redescribed by Donisthorpe. I have also had the 

 opportunity of examining the type and from the description which 

 I wrote out at the time, it is clear that the only feature in which 

 it differs from the Rhodesian specimens (on which the foregoing 

 descriptions have been based), is the presence of 5 or 6 fine setae 

 on the lower margin of the posterior tibiae. Notwithstanding the 

 importance which some authors have attached to the absence or 

 presence of such setae, I can not for my part regard the lack of those 

 structures in the Rhodesian specimens as the slightest justification 

 for separating the latter as a variety.

Q|., 13-14*7 mm. Colour, sculpture and pilosity like that of macu- 

 latus i. sp. but the head is more castaneous red, becoming paler 

 towards the posterior angles. The ochreous spots on the 1st and 

 2nd abdominal segments coalesce and form a band on each side, the 

 spots on the 3rd segment very dark and small, or almost obsolete. 

 Head nearly one-fifth longer than wide, the sides less convex and 

 the posterior angles less rounded than in the type of the species. 

 Scapes longer, extending beyond the hind margin by two fifths of 

 their length. Mandibles longer. The anterior margin of the lobe of 

 the clypeus more distinctly crenulate than in the type of the species. 

 Thorax less convex lengthwise than in the type. Scale thicker, 

 especially its dorsal edge. Tibiae setose below.
