Figures 172-178 



Type (male). — Black: labrum except median stripe; mandibles, 

 except tips ; narrow apical border and lateral spots on clypeus ; small 

 spot on scape below; small round spot on either side of anterior 

 ocellus ; minute spot between antennae ; posterior orbits broad below, 

 narrow above; posterior border of pronotum; sides of protliorax 

 almost entirely; narrow lateral line on scutum above base of wings; 

 curved, interrupted fascia on posterior border of scutelluni; inter- 

 rupted fascia on metanotum; curved fascia on propodeum, broadest 

 on posterior surface; lateral angles and almost entire sides of pro- 

 podeum; large spot on metapleura; mesopleura and mesosternum 

 almost wholly; widely separated lateral spots on first tergite, broad 

 at lateral end and narrowed to a point at dorsal end; continuous 

 fasciae on tergites 2-4, that on second alm.ost inclosing a pair of discal 

 spots, those on third and fourth biemarginate on anterior border; 

 lateral spots on tergites 5 and 6; lateral spots on sternites 2-5; 

 legs except black line above on anterior femora, black line below and 

 broken line above on anterior tibiae, black spot above at base of the 

 other tibiae and black spot below on each segment of anterior and 

 middle tarsi; yelJovx On some i:)arts of the body the yellow has a 

 greenish tinge and the doi^al part of the tergal fasciae is pale. 



The antennae are stout, the scape being unusually thick and heavy. 

 Segments 9-11 of the flagellum are broadened and flattened below 

 but are not much excavated, the surface being only slightly concave. 

 The apical segment is rounded, slightly curved and truncate at the 

 apex. The spines of the anterior metatarsus, of which one bears 

 seven and the other six, are peculiar in form, most of them, but not 

 all, being broad, flat, and stout (fig. 177). The intermediate femora 

 are dentate, each bearing at the base a single stout spine and apical 

 to this a series of very small spines. The middle tibia on its inner 

 side shows a slight swelling at the apical end. The middle meta- 

 tarsus is strongly curved and compressed. Below at its proximal 

 end is a slight protuberance covered with fine stiff hairs and the 

 anterior border at the apical end is developed into a broad, thin, 

 wedgelike process (fig. 174). This is true also of the second seg- 

 ment, and to a less degree of the third. The second sternite bears a
