and Lower Burma I only procared typical forms. A specimen 

 from Thagata in Tenasserim, procured by Fea, has been separated 

 by Dr. Forel as var. thcujatemis. It differs in having the legs as 

 well as the whole of the antennae brown, and being longer (S-o mm.) 

 and more robust than the type.

 punctures ; the anterior pair of legs, and the tibiae and tarsi of 

 the intermediate and posterior pair very dark brown ; mandibles 

 and scape of the antennae light, somewhat reddish brown, flagellum 

 fuscous ; pilosity pale, very sparse except on the scape of the 

 antennae and tibiae and tarsi of the legs ; pubescence almost

 Museum and in the one other specimen I have). Head nearly 

 square, almost as broad as long, the occiput broad, transverse, 

 slightly rounded, the cheeks very convex ; the eyes placed to the 

 front and above the middle of the head ; mandibles broad from 

 base, as in all the species of the genus, somewhat coarsely longi-

 very slightly projecting, subvertical; antemial carinae short, very 

 close together ; antennae short and stout, the scape barely extend-

 on the front below the vertex. Thorax narrower than the head ; 

 the pronotum \'ery flat, snbmargined posteriorly and laterally, 

 arched in front ; meso-metauotal suture arched, anteriorly distinct, 

 mesonotum longitudinally oval, raised ; the thorax in profile emar- 

 ginate at the meso-metanotal suture ; metanotum shaped as iu 

 S. nhji-a, but shorter and not so compressed ; legs comparatively 

 long and slender. Pedicel proportionately very long, both nodes 

 with long petioles anteriorly ; 1 st node large, as broad as the 2nd 

 node and much longer, this latter cup-shaped, not constricted pos-
