34 J. Wood-Mason — On new and little-known Mantodea. [No. 1, 



hyaline on both sides ; with the apex of the anterior area and six bands all 

 commencing at the anterior margin and extending successively from the 

 base of the organ further and further into the posterior area (where they pass 

 insensibly into the paler ground-colour) very much darker smoky-quartz- 

 colour ; with the venation and membrane between these bands much 

 lighter than elsewhere, so that the organs appear alternately banded with 

 light and dark ; and with the outer margin of the posterior area very 

 narrowly semihyaline. 



Fore femora and coxae bifasciated externally with fuscous, the latter 

 furnished with 8 — 9 minute, slanting, sharp, conical spinules on the upper 

 crest, the former black on the inner side from the base nearly to the 

 apex ; fore tibiae armed with 10 + 15 spines on their two inferior edges ; 

 the femora of the four posterior legs present obscure traces of transverse 

 fasciae. 



Abdominal terga black-fuscous with the lateral margins paler. 



Total length 85 millims. ; of pronotum 31'5, of which the anterior 

 lobe is 7, width of pronotum at supracoxal dilatation 7*75 ; height of head 

 7, breadth of head 9 5 ; length of fore coxa 16, femur 19*5 ; of intermediate 

 femur 20, tibia 18-5 ; of posterior femur 24, tibia 25 ; length of tegmina 67, 

 breadth of tegmina (across middle) 12-5 ; leng^th of wings 59. 



Hae. Cameroon Mountains, West Africa. 



The female differs from the male in her larger size and stouter build, 

 and in her shorter and broader organs of flight, the tegmina being only 

 about li times the length of the pronotum and the wings reduced nearly to 

 the form and proportions of a quadrant of a circle.
