segment of funiculus three times longer than second, remainder sub-equal, 
apical as long as the two preceding combined. Eyes large, flatly convex, 
placed at middle of sides. Thorax twice as long as broad through pronotum, 
sutures well defined. Pronotum one-third broader than long, strongly

in front, constriction between mesonotum and epinotum deep and wide with 
the spiracles prominent on top at each side. Epinotum as long as broad, 
strongly convex laterally, sides almost parallel ; in profile pronotum and
