252 A NATURALIST IN THE TRANSVAAL. 



punctate, its apex black ; corium very darkly punctate, its outer 

 margins luteous and levigate, inwardly edged with black; 

 membrane pale testaceous, exhibiting from beneath a black 

 spot on each side. Body beneath, legs, and rostrum pale reddish 

 ochraceous. 



The second joint of the antennae is longest, and the apical 

 joint is somewhat infuscated. 



Long. 11 millim. 



This species may be distinguished by the pronotal spines 

 being much less directed forwardly than is usual in the genus, 

 and also by the two black spots seen through the membrane 

 near apex of abdomen. (W. L. D.) 



Lyg<zus planitia, sp. n. (Tab. III. fig. 7.) 



Body above reddish orange, finely pilose; antennae, eyes, 

 central lobe to head, and a large basal spot at inner margin of 

 eyes, two large wide discal longitudinal fasciae to pronotum 

 (strongly constricted anteriorly, fused near anterior margin, 

 and connected with lateral margins at base and centre), scu- 

 tellum excluding apex, apical half of clavus and claval margin, 

 a large discal spot to corium connected with its lateral margin 

 for half its length, membrane excluding lateral and apical 

 margins, rostrum, coxae, legs, margins and sutures of sternum, 

 and sutural fasciae to abdomen, black ; margins of membrane 

 pale fuscous. 



Long. 10 to 12 millim. (W. L. D.) 



Lygaus desertus, sp. n. (Tab. III. fig. 9.) 



Closely allied to L. planitia, but differing by the following 

 characters : corium with the lateral and apical margins, a 

 broad claval marginal fascia, and a longitudinal fascia extend- 

 ing from the base where it is narrowest, to the centre of the 

 apical margin where it is broadest, black. Membrane pale 

 grey, hyaline, with an irregular reddish spot at the centre of 

 basal margin, and a small obscure fuscous spot at inner apical 

 margin. 



Long. 10 millim. (W. L. D.)
