thorax, though without traces of wing-insertions. The pro- and me- 

 sonotum and the scutellum are coarsely and umbihcately punctate like 

 the head, and the basal portion of the first gastric segment is covered 

 with coarse, sparse punctures in addition to the general fine and dense 

 punctuation of the surface. 



As Mayr pointed out, the genus Bradopon era is allied to Proceratmm. 

 It is still moie closely related to Discotltyrea, of which five species 

 are known: V. testacea Roger of North America, autardica Emery of 

 New Zealand and clavicornis Emery of German New Guinea, globus 

 FoREL of Java and oculata Emery of Kamerun. 



In this genus, however, the antennae of the worker are 9- instead 

 of 12-jointed, the eyes are minute and the frontal carinfe, clypeus 

 and petiole have a different confoimation. These differences show 

 that Bradopo}iera is much more primitive than any of the recent 

 genera of Proceratini. The workers of all of these genera, moreover, 

 are hypogseic in their habits, whereas B. meieri was, in all probability, 

 an epigaeic or even arboreal species.

Male (Fig. 5). Length 3,5 — 3,75 mm. 



Head, including the mandibles longer than broad, with very large 

 and prominent eyes and ocelli. Mandibles well-developed. Clypeus 

 convex, with entire, subangular anterior border. Antennae very long 

 and slender, 13-jointed; scape more than twice as long as broad, first 

 funicular joint half as long as the scape, remaining joints cylindrical, 

 subequal, seven or eight times as long as broad. Mesonotum with 

 well-marked Mayrian furrows. Epinotum in profile with subequal 

 base and declivity forming an obtuse angle with each other. Petiole 

 nearly twice as long as high; its node low and rounded posteriorly. 

 First gastric segment with a small protuberance on its anteroventral 

 margin. Genital appendages and pygidium short and rounded. Legs 

 slender. Wings large and broad. 



Head, gaster and much of the thoracic dorsum and petiole covered 

 with a white air-film so that the sculpture cannot be clearl}^ seen.
