KONGOBATHA'i new genus. 



In the arrangement of the Mantidae we place this genus after 

 Neomantis. From all known genera of the Tropidomantes the 

 present is separated by the strongly elevated lateral portions of 

 the vertex and the slender pronotum, which shows a minimum 

 development of the medio-longitudinal carina ;^' in the majority 

 of genera of the Tropidomantes this carina being very decided and 

 lamellate. The insect is much more attenuate than in Tropidotnantis 

 and consequently very much more attenuate than in Neomantis, 

 but the spination of the ventro-internal margin of the cephalic 

 femora and very elongate supra-anal plate agrees instead with the 

 latter genus. 



Genus monotypic. Genotype. — Kongobatha diademaia here de- 

 scribed. 



Generic description (from female, male unknown). — Size small, 

 normal for the Tropidomantes. Form slender, tegmina and wings 

 much narrower than in Tropidomantis, narrower even than in Xan- 

 thomantis, with apices acute and sharply rounded. Head much 

 less transverse than in Tropidomantis and Neomantis, facial scutel- 

 lum very strongly transverse, occiput distinctly quadrisulcate, the 

 juxta-ocular portions raised high above the eyes in blunted angulate 

 projections, the median sections much lower, somewhat swollen 

 but with dorsal margin transverse." Ocelli moderately well devel- 

 oped, forming a triangle very slightly broader than high. Pro- 

 notum slender, slightly longer than cephalic coxa, margins smooth; 

 supra-coxal expansion very weak with its margins very feebly and 

 broadly convex; medio-longitudinal carina decided, but not as 

 strongly developed or lamellate as is usual in the Tropidomantes, 

 completely severed by the supra-coxal transverse sulcus, disappear- 

 ing mesad on collar of pronotum. Tegmina with veins as character- 

 istic for the group; false veins regular, not irregular as in Tropi- 

 domantis or very irregular as in Neomantis; marginal field very 

 narrow, with its immediate margin opaque; other portions of teg- 

 mina and wings hyaline. Wings projecting slightly beyond teg- 

 mina. Cephalic coxa with margins unarmed but showing a few 

 very minute hair follicles, which are more numerous along the 

 straight dorsal margins of the cephalic femur. Cephalic femur 



" One of the aboriginal tribes of Queensland. 



12 Excepting, as to this feature, the aberrant Epsnmantis (ortricoides (Haan) 



" Evidently a high specialization of the type shown by Tropidomantis.
