Uhluxga, n. g. 



Head moderately long and broad, obliquely depressed, the lateral margins con- 

 cavely sinuate, central lobe reaching the apex, which is rounded ; eyes somewhat 

 prominent ; antennae 4-jointed, 2nd joint very long, basal joint short, moderately 

 incrassated, not quite reaching the apex of the head. Pronotum broader than long, 

 strongly depressed anteriorly, the lateral margins almost straight or very slightly 

 and obscurely sinuate ; the lateral angles obtusely prominent in the male, subacutely 

 spinous in the female ; the posterior margin concavely sinuate. Scutellum with the 

 basal half moderately gibbous, subtriangular, narrowed towards apex, which is 

 obtusely angulated. Corium not reaching outer margin of abdomen, exposing only 

 connexivum in the male, but also part of the abdomen in the female. Membrane 

 considerably passing the apex of the abdomen. Rostrum extending beyond the 

 posterior coxae. Abdomen in the male with a broad and elevated central longitudinal 

 callosity, extending from base to anal appendage ; in the female this is replacd by a 

 broad, central, longitudinal sulcation. 



This genus is remarkable by its strong sexual differences, the 

 extended membrane, the dilated abdomen, &c , and is difficult to closely 

 ally with another described genus. The sulcated abdomen in the 

 female sex, with other characters, have induced me to place it in that 

 portion of the Pentatomino! distinguished by Dallas as his Family 

 Halydidcs, and used by Stal as a section only of the whole Sub-Family. 



Uhlunga ttpica, n. sj). 

 Body, above, ochreous, thickly covered with dark coarse punctures ; scutellum 

 with a distinct central levigate, longitudinal, pale fascia on its apical half; membrane 

 bronzy-brown ; antennae with the 1st and 2nd joints ochraceous, 3rd and 4th joints 

 (excluding their bases) infuscated, 2nd joint in the male with its apex infuscated, 

 3rd and 4th joints subequal in length, and together about equal to that of 2nd. 

 Eyes fuscous. Rostrum ochraceous, with its apex pitchy.
