(•2. Disk of pronotum generally unicolorous, sometimes longitudinally striped, 

 rarely irregularly and rather obscurely mottled ; ovipositor not narrower in 

 the middle than beyond, and broader than the frontal fastigium. 



sieindachneri^ 

 b^. Prozona broadest scarcely behind the middle of the metazona, at least in the 

 female; ovipositor rather strongly curved, not narrowed in the middle; hind 

 femora basally stouter than in the other species diaholica. 



Tropizaspis ovata sp. nov. 



Head rather large, testaceous, the fastigium narrower than the de- 

 pressed basal joint of the antenna?, anteriorly truncate, sulcate. Pro- 

 notum nearly half as long again as broad, broadest posteriorly, ovate, 

 anteriorly truncate, the prozona plane, the metazona gently tumid, the 

 whole disk glistening testaceous longitudinally streaked with black, espe- 

 cially down the middle and at the sides ; lateral carina? rather sharp and 

 somewhat prominent laterally but scarcely elevated, diverging continu- 

 ously from the very base, the hind border strongly rounded and margined ; 

 median carina sharp but feeble, equal, percurrent ; lateral lobes uniform 

 testaceous. Legs testaceous, feebly clouded with fuscouS; the hind femora 

 less than half as long again as the pronotum. Abdomen uniform testa- 

 ceous ; supraanal plate of male triangular, apically rectangulate but 

 rounded, the sides with a slight basal tooth ; anal cerci stout, brief, coni- 

 cal, scarcely longer than basal breadth ; supragenital plates large, tumid, 

 superiorly carinate, overlapping each other and surpassing laterally the 

 subgenital plate, together apically rounded ; subgenital plate with dis- 

 tinct styles. 



Length of body, 21.5 mm.; pronotum 11.5 mm.; breadth of same, 

 8 mm. ; length of hind femora, 16.5 mm.

Tropizaspis castanea sp nov. 



Head rather large, testaceous, irregularly marked with fuscous in 

 slender stripes, the fastigium dotted with luteous, a little narrower than 

 the first antennal joint, apically truncate, plane ; antennae long enough 

 to reach a little beyond the hind femora, testaceous broadly banded with 

 fuscous. Pronotum with asymmetrically clepsydral disk, about half as 

 long again as broad, broadest posteriorly, very gently tumid, faintly pec- 

 tinate transversely and posteriorly faintly rugulose, castaneous, the lateral 

 carinae distinct but rather blunt, feeble and converging on the prozona, 

 on the metazona diverging and with the bluntly margined hind border 

 forming a rather short ovoid; median carina faint, equal, percurrent; lat-
