same side with an other linear chitinous process (apparently- 

 made up of hairs glued together), tibiae rather stout, slightly- 

 curved, the inner margin with scattered hairs from the base to 

 the middle, behind the middle fringed with long_ hairs. 



imitator Uhl. 



3 (2) The spongy pit of the third J^ antennal joint dilated on the under 



side, its lower margin studded with spinules, fourth joint armed 

 with a spine. Middle coxae in the c? thicker than the hind coxae, 

 trochantera not or scarcely smaller than the hind trochantera, 

 femora fringed with long hairs along the whole inner margin, the 

 longest hairs being in the middle, tibiae straight, their basal 

 half thicker than the apical half. Hind trochantera not incras- 

 sated, unarmed. 



4 (5) Mesonotum conspicuously broader than long in both sexes, the 



median yellow spot not or scarcely narrower than the pronotal 

 spot. Mesosternum yellow, unicolorovxs. Second J* antennal 

 joint beneath with a slender spine at the base, the curved basal 

 part of the third joint three-fourths the length of the whole joint, 

 the spongy pit occupying only the apical fourth with a short s-pin- 

 ule at its base, fourth joint about half the length of the third, 

 curved from the base to the apex with the spine in the apical 

 half. Middle tibiae in the c? fringed with rather short 

 hooked hairs on the inner side of the basal half. Hind trochan- 

 tera in the (^ rather thicklv pilose above, femora incrassated 

 and strongly curved, fringed with moderatelv long hairs on the 

 inner side near the base, the apex with two bunches of long hairs 

 glued together, tibiae rather stout, a little curved, attenuated at 

 the base and inserted before the apex of the femora in their outer 

 side, fringed with rather short and stiff straight hairs on the 

 upper inner side and emitting a backwardlv directed fascicle 

 of very long hairs glued together from a point somewhat behind 

 the base on the inner side. Rileyi Berer. 



5 (4) Mesonotum scarcely ((5*) or slightly (9) broader than long, the 



median yellow spot dis+inctlv narrower than the pronotal spot. 

 Mesostemu^m yellow with the anterior margin and two poster- 

 iorly diverging bands brownish black, these bands not reaching 

 the posterior margin, dilated near the anterior margin. Second 

 S^ antennal joint beneath at the base with a small tubercle bear- 

 ing a fine hair (not visible when the joint is strongly deflected), 

 the curved basal part of the third joint one-half the leneth of the 

 whole joint, the spongy pit occupying the at)ical half with a long 

 slender spine at its base, fourth joint scarcely shorter than third, 

 curved near the base and at the extreme apex with the curved 

 spine in the basal half. Middle tibiae in the (^ fringed with 

 short hooked hairs on the inner side from the base almost right 

 to the apex. Hind legs in both sexes simple, straight and 

 hairless. tenuipes Mein. 



(') (1) Mesonotum much broader than long in either sex. without a median 

 yellow spot. Connexivum velvety black. Eves reaching the 

 mesopleura. Second and fourth antennal joint in the c? in- 

 serted rectangularly in the side of the apex of the preceding 

 joint, first joint with a submedian spine above and beneath, its 

 upper margin sinuate behind the middle owing to the apical part 

 of the joint being strongly upturned, second joint beneath at the 

 base with a stiff hair (not visible when the joint is deflected), 

 third joint with the short basal part straight, the curved apical 

 part considerably thicker than the basal part and niore than two 

 thirds the length of the joint with a very shallowly impressed 

 almost flat spongy pit, the'^lower'margin of the pit with some 

 stiff hairs and its base with a short tooth-like projection, fourth 

 joint a litte longer than third, unarmed, rectangularly curved
