HOMOPTEEM 



spined and reaching considerably beyond the internal angles of the tegmina but not to their tips; 

 scutellum robust, subtriangular, entirely exposed, recurved, tip widely bifurcate. Tegmina broad, 

 hyaHne, base coriaceous and punctate; veins strong; five apical and two discoidal cells; tip rounded; 

 apical limbus broad ; a large, heavy, punctate stigma on about the middle of the costal margin of the 

 corium. Legs simple; all tarsi about equal in length. 



Type nodosus Buckton. 



Geographical distribution : This is an African genus which is apparently not often seen and is 

 represented by onl}' three species as follows : 



1. mabirensis Chiiia, Ann. Mag. Nat. Hist. XI : 463 (igaS). — Pl. 14, Africa, Uganda, Mabira. 



fig. 236. 



2. nodosus liuckton, Trans. Linn. Soc. ZooL IX : 33o (igoS). West Africa, Cameroons. 



3. pattersoni Distant, Rhynch. Notes iS"] (igi6). Africa, Gold Coast, Aburi. 



267. Genus UMFILIANUS Distant 



Umfilianus Distant, Rhynch. Notes LVII : 496 (igi5). 



Characters : We have never seen either of the described representatives of this genus and 

 neither of them has been recognized or figured in the hterature of the family except in catalogue 

 references since their original descriptions. We can therefore only quote Distant's generic description 

 as follows : 



« Pronotum elevated, the front obhque, the posterior process moderately slender, tricar- 

 inate, convex at base, well separated from scutellum (which is quite exposed and about as long 

 as broad), its apical area impinging on the tegminal suture and the apex about reaching the inner 

 tegminal margin, lateral angles subprominent ; ocelli almost as far apart from each other as from 

 the e^^es; face a Httle concavely declivous; legs simple; tegmina with four apical areas. 



» Hy the shape and direction of the posterior process resembUng the genus Indicopleustes 

 Dist., but altogether removed from the division in which that genus is located by the absence of 

 lateral pronotal processes. » 



From the above description it v\ ould appear that the genus should be recognized by the absence 

 of suprahumerals, the shape of the posterior process, the sloping metopidium and the four apical cells 

 of the corium. 



Type declivis Distant. 



Geographlcal distribution : This genus is known only from two African species as follows : 



1. declivis Distant, Rhynch. Notes LVII : 4^6 (igi5). Africa, Mashonaland. 



2. fenestratus Gerstacker, Deck. Reis. Ost. Afr. II : 42^ (1873). German East Africa. 



268. GENUS TIBERIANUS DlSTANT 



Tiberlanus Distant, Ann. Mag. Nat. Hist. XVI : 4g3 (igiS). 



Characters : Near the preceding genus but differing particularly in the strongly tricarinate 

 metopidium. Head subquadrate, broader than high; base weakly arcuate; eyes ovate; ocelli small, 

 inconspicuous, about equidistant from each other and from the eyes and situated above a line drawn
