Heteroptera from the Transvaal. 



The British Museum has secured a set of the specimens of 

 Rhynchota collected by the Rev. H. A. Junod at Shilouvane, 

 Zoutpansberg, Northern Transvaal, and this paper refers to 

 undescribed species found in the collection. The Capsidaj 

 have already been described {ante, p. 196 et seq.), while the 

 Homoptera, poorly represented, are reserved for future treat- 

 ment. The greater part of the Zoutpansberg district possesses 

 a subtropical climate and is much covered with bush and 

 dwarf forest, thus being in strong contrast with the high and 

 barren veld which constitutes so large a portion of the Trans- 

 vaal landscape. I was therefore not greatly surprised to rind 

 both many new species and others known in entomological 

 record, which I had neither seen nor secured during four 

 years' collecting in other parts of the Transvaal. Two 

 genera, Geomorpha and Phonolibes, both hitherto represented 

 only by a single West-African species, are now found to have 

 each a representative species in North Transvaal. 



All the types are contained in the National Collection. 



Fam. Pentatomidae. 



Subfam. Cydnlnm. 



Gnathoconus elovgatus, sp. n.

 of antennas, tibiae (excluding apical third), lateral margins of 

 the fourth, fifth, and sixth abdominal segments, and the apical
