"The parts of the mouth are exposed and the antennae much

According to the figure the thick black antennae are a little 

 shorter than half the length of the body, and the prothorax is 

 black, yellow on each side. Mesothorax thick, black above, yel- 

 low laterally below the wings and on the ventral part ; on the 

 sides two black angulose bands, connected anteriorly, a black 

 line on the lateral suture and the stigma largely black ; some 

 white villosity on the thorax above and laterally ; metathorax 

 short, above black with median dorsal band and one on each side 

 yellow ; front margin transversely yellow ; the sides and ventral 

 part yellow with some indefinite blackish marks above the legs ; 

 abdomen long, narrow, above black, the transverse sutures and 

 the lateral margins finely yellow ; below bright yellow with a 

 longitudinal black band not far from the lateral margin ; a fine 

 black villosity on the abdomen ; superior appendages yellow, in- 

 ternally black, twice longer than the last segment, broad at 

 base, then C} r lindrical, curved inward and downward, tip rounded ; 

 viewed laterally, they are inserted in a short, basal joint, not to

 femur brownish anteriorly ; tibia black on tip ; tarsus with first 

 joint as long as the other together ; claws black. Front wings 

 hyaline, three times longer than broad, front margin nearly

 cept the costa, subcosta and mediana, which are yellowish white ; 

 the subcosta below at base black ; twenty to twenty-one blackish 

 costals before a very small brown pterostigma, which is just above
