2. Additions to the Rhyncliotal Fauna of the Ethiopian 

 Region. By W. L. Distant. 



[Eeceived January 27, 1881.] 



(Plate XXXI.) 



The Rhyiiehota of the Ethiopian Kegion form a group of insects 

 that has been fairly worked by entomologists, and of which sufficient 

 material exists to warrant the hope that in a few years we may 

 have a moderately complete list of the fauna. The late Prof. Stal 

 attempted, and at the time succeeded in producing a Monograph, 

 ' Hemiptera Africana,' which was complete to date, but now re- 

 quires much supplemental work. I have for some years had con- 

 siderable facilities in this direction, and have also lost no opportunity 

 of acquiring African specimens. The following descriptions relate 

 to undescribed species from collections which have come into my 

 possession from various sources since I wrote my " Notes on African 

 Hemiptera Hetcroptera," in the 'Entomologist's Monthly Magazine,' 

 vols. xiv. and xv. With the exception of two species from Nyassa 

 and South-eastern Africa, they have all been received from the 

 Calabar district. West Africa. 



Hemiptera HeteroI'tera. 

 Fam. Pentatomid^. 



TrOPICORYPHA FORMOSA, n. gp. 



2 • Above bright green, shining ; anterior two thirds of lateral 

 pronotal margins, a small spot on each side of the head at base 

 behind the eyes, ocelli, connexivum, underside of body, and basal 

 halves of femora luteous. Antennse pitchy, third joint much longer 

 than second (fifth wanting). Head with the central lobe sub- 

 prominent, lateral lobes rounded and somewhat reflexed at apical 

 angles. Pronotum with the lateral margins straight, reflexed ante- 

 riorly. Lateral angles subprominent and subacute. Membrane 

 pitchy, margins and apex paler. Rostrum reaching posterior coxse, 

 basal joint luteous, remainder pitchy. Tibiae above strongly sul- 

 cate, tarsi pitchy. Ventral spiracles fuscous. 



Long. 18 milhms., lat. pronot. ang. 10. 



Hab. Calabar. 



This species is strikingly distinct from any other of the genus, 

 both in size and colour. Bright green with luteous markings ap- 

 pear to be somewhat representative colours in the West-AtVican 

 Pentatomidse. 



Note.- — In placing this species in the genus Tropiconjpha, INLiyr, 

 and the following species in the genus Hahjomorpha, Mayr, I rely 

 more upon the diagnostic characters given by Stal (En. Hem. 

 pt. V. pp. .56 & 57) than on those given in Dr. Mayr's original 

 description (Verb. z.-b. Ges. Wien, xiv., pp. 910 & 911), which.
