 two and one-half of the third funicle joint; first four funicle joints of 

 equal length, the last two subequal and a little longer than the pre- 

 ceding, first thi'ee hardly wider than long, the last three more dis- 

 tinctly transverse, the sixth about twice as wide as the first; club 

 oval, obtusely rounded at apex, hardly wider than the preceding joint 

 and as long as the last three funicle joints combined. Length, 0.8 to 

 1.1 mm. 



Coloration nearly as in female, but the front sulphur yellow instead 

 of orange; band on occiput above the neck blackish; pale streak on 

 sides of abdomen a little wider, deeper yellow and more distinctly
