b. First abdominal segment petiolate, much longer than broad, clearly separated from 

 the second ; eyes converging at the apex; front with a furrow ; depression between 

 the scutellum and mesonotum foveolate ; median segment without an area, shining, 

 farrowed down the middle ; body almost impunctate, covered with a close fulvous 

 pubescence, and usually well marked with yellow spots; wings fulvous, fuscous, or 

 yellowish, without fascice.

Antennae reddish, the scape yellow beneath ; joints 2-7 of the flagellum black above ; 

 the basal joint shorter than the third, which is distinctly longer than the first and 

 second united ; the third joint one quarter longer than the fourth. Head narrower than 

 the thorax ; above densely covered with golden-fulvous pubescence and sparsely clothed 

 with long fuscous hairs, the clypeus with a silvery pile ; front bearing scattered punc- 

 tures, the furrow well developed ; ocelli forming a triangle ; the head in front below 

 the antennae, entirely, and the basal half of the mandibles yellow. Mesonotum with a 

 dense fulvous pile and rather long black hair ; marked with fine scattered punctures ; 

 the pleurae very shining, impunctate, sparsely haired ; the breast covered with a dense 

 silvery pile. The depression in front of the scutellum foveolate throughout. Median 

 segment with a gradual rounded slope, covered rather closely with long dull fulvous 

 hair ; the middle furrow becoming much wider and deeper beyond its junction with 

 the lateral keels, but not reaching the apex. Mesopleural furrow reaching a little 

 beyond the middle, and an oblique curved furrow runs down from the tubercles, but 

 not reaching the longitudinal furrow. Over the hind legs is a short wide furrow with 

 three stout keels. The thorax has the margin of the pronotum, the tegulse, tubercles, 

 the greater part of the mesopleurae, the metapleurae (except a black line at the apex), 

 two broad longitudinal lines on the mesonotum, the scutellum (except a longitudinal 

 line at the base), two small oval oblique marks at the base of the median segment, and 

 two large ones occupying the greater part of either side at the apex, yellow. Petiole 

 as long as the second segment, dilated at the apex ; the second segment at the base
