length of the third antennal joint, and by a somewhat greater distance from the eyes. 

 Antennae stout, densely covered with a pale pile, the third joint more than doable the 

 length of the second, and one-third longer than the fourth. Pronotum with a gradual 

 slope to the head ; the top transverse, with the angles oblique ; the pleurae behind 

 deeply excavated. Mesonotum closely and somewhat strongly punctured, the central 

 furrow wide ; mesopleurse more closely punctured than the head, the furrow crenulated. 

 Scutellum shining, very slightly punctured, and with an olivaceous tinge. Central area 

 of the median segment with the central furrow wide, and bearing some stout, irregular, 

 almost oblique, keels ; the rest of the median segment coarsely and closely transversely 

 rugose, and covered densely with longish white hair. Metapleurae finely, closely punc- 

 tured, much more closely and strongly than the mesopleurae. Petiole wide, gradually 

 dilated to the apex, a little shorter than the second segment, shining, impunctate. 

 The penultimate segment closely punctured, densely covered with a silvery pubescence. 

 Pygidial area longish, gradually narrowed to the apex, which is rounded and half the 

 width of the base ; densely covered with stiff, depressed, fulvous-golden hair, and with 

 scattered punctures. On the petiole, near the apex, there is a broad yellow stripe with 

 a square indentation in the middle behind ; the second, third, and fourth segments bear 

 an elongated oval mark on each side. Legs covered with a pale silvery pubescence, 

 which is rather long on the coxae, trochanters, and femora ; the tibial spines glistening 

 white — the inner spur blackish, the outer one partly testaceous, the longer spur fully 

 two-thirds the length of the metatarsus ; there is a yellow streak on the tibiae behind. 

 Cubital nervure received slightly beyond the middle of the wing. 



The male wants the yellow on the thorax (except a small irregular mark on the 

 metanotum), and has the mark on the petiole interrupted. For anterior tibiae and 

 tarsi, see fig. 15 a.
