slender, with unguicular sulcus at end of proximal two-fifths; three 

 discoidal spines; four spines on ventro-external margin and an addi- 

 tional small spine on external and internal genicular lobe; between 

 but inside the first two spines of the ventro-external margin is a 

 small round concavity into which, when the limbs are flexed, fits 

 the apex of the terminal spine of the ventro-external margin of 

 the cephalic tibia; spine formula on ventro-internal marginilililililil. 

 Cephalic tibia with ventro-external margin armed with nine spines, 

 increasing in length distad, except that the second is longer than 

 the third and the fourth longer than the fifth; ventro-internal margin 

 armed with eleven spines which increase regularly in length distad. 

 Caudal metatarsus very slightly longer than the combined length 

 of the succeeding tarsal joints. Cerci absent in specimen at hand. 

 Supra-anal plate very elongate. 



Kongobatha diademata new species. (Plate I, figures 1 and 2.) 



The form of the specialized vertex is a very distinctive feature 

 in this species. The insect does not look like the other species of 

 the Tropidomantes and it is only when closely examined that the 

 affinity is apparent, the head and pronotum being then seen to 

 show only a distinctive development from the same type found in 

 Tropidomantis. 



Type. — 9 ; Queensland, Austraha. [Hebard Collection Type No.

In addition to the features given in the generic description, we 

 would note the following. Facial scutellum five times as broad 

 as high. Short, somewhat irregular, oblique veinlets connect the 

 marginal and mediastine veins of the tegmina and of the wings 

 proximad only. Stigma indicated as a colorless line running from 

 the discoidal to near the humeral vein, beyond which from a number 

 of irregularly confused veinlets springs the median vein. Wings with 

 distal portion of anterior field as long as its basal width, discoidal 

 vein triramose. Cephalic femora with ventral surface supplied 

 with hairs and within the marginal spines minutely and irregularly 

 denticulate; spines of ventro-internal margin extend to opposite 

 distal margin of femoral brush, the first two and the last of the 

 longer spines exceeding the other longer spines very slightly in 

 length. Supra-anal plate fully twice as long as basal width, lateral 

 margins weakly concave convergent proximad, thence straight in 

 the gradually narrowing slender distal portion to the acute apex, 

 which extends well beyond the comparatively elongate subgenital 

 plate.
