One adult example and five larva) from S.E. Rhodesia, 

 Melsetter, Gazaland, 3000 ft. Mount Cliirinda, " in the 

 forest," October 6, 1905, collected and presented by Guy 

 Marshall to the University Museum, Oxford. 



This species resembles imjnxssns, differing in the shorter 

 pronotum, and the entire lateral carinas at the humeral 

 angles, but behind on the process strongly interrupted, 

 irregular, and disappearing backward before the apex. In 

 inipressus, according to Bolivar, the lateral carinee present 

 a crenulate margin and the pronotum measures 14 mm. 

 instead of 11 mm. as given above. 



Genus Rytinatettix, nov. 



Resembling Prototettix, Bolivar, but having the stature very small, 

 nigose-tuberculose, the posterior ocelli placed below the middle of 

 the eyes ; the vertex wider than one of the moderately small ej^es, the 

 frontal costa widely sulcate ; the antennte inserted little before (below) 

 the eyes, the inferior lateral margins of pronotum above the insertion 

 of the elytra sinuate or arcuately excavate ; the elytra minute or small ; 

 wings abbreviated, the lateral lobes of pronotum little reflexed out- 

 wards, somewhat widely rounded and obliquely truncate or hebetate ; 

 the anterior and middle femora compressed, margins undulate-lobate, 

 the posterior femora somewhat incrassate, and the first articles of the 

 posterior tarsi little longer than the third. 



The type k Frototettix fossiclatus, Bolivar. To this genus 

 also belongs the species Prototettix lohulatus (St;ll.), Bol., 

 both inhabiting South America. The creation of the new 

 genus, EytinateUir, leaves only the African species remain- 

 ing in Bolivar's genus Frototrtti.c, namely, F. iviirrcssus 

 (Stal), Bob, and F. africanus, Hancock. Giglio-Tos* de- 

 scribed a species under the name Faratcttix horellii, which 

 appears to be synonymous with Bi/tinatcttix lobulatus 

 (Stal.).

These examples were previously determined by Brunner
