and coarse, laminate, boot- shaped, the basal half subequal, punctate 

 and straight, beyond expanding and at the same time feebly bifurcate, 

 the upper fork as long and more than half as broad as the base, feebly 

 incurved, strongly upcurved, apically tapering slightly and well 

 rounded, the lower fork at right angles to it, forming only a rounded, 

 downward and posteriorly projecting lobe, so that the apical margin 

 of the whole is deeply and roundly emarginate below, the whole sur- 

 passing a little the supraanal plate; infracercal plates wholly obscured ; 

 subgenital plate short and broad, scarcely so broad apically as long, 

 the apical margin thickened, but hardly otherwise either elevated or 

 prolonged, entire; upper valve of ovipositor abruptly upturned apic- 

 ally and sharply acuminate, the upper outer carina feebly serrate.
