2. Orphula meridionalis, sp. n. 



About the same size as, but somewhat more robust than, 0. pagana, Stal. General colour dark brown, 

 relieved by green on the dorsum of the prothorax and on the tegmina above. 



Face oblique, nearly straight when viewed from the side ; vertex between the eyes a little narrower than the 

 shortest diameter of one of them, the fastigium provided with a raised rim and projecting forwards about 

 as far as its posterior width, the sides nearly straight and its apex acute, in this respect recalling to mind 

 the various species of the genus Orphuletta. Antennae about as long as the head and pronotum together, 

 the basal joints flattened and moderately broad, but, owing to the slight enlargement of the apical joints, 

 these members can scarcely be said to be ensiform. Pronotum with the dorsum flat, widening but gently 

 posteriorly, the sides nearly perpendicular, front edge straight, the hind margin broadly angulate, but 

 with the apex gently and rather widely emarginate ; lateral carina? nearly as prominent as the median, 

 parallel to the last transverse sulcus, which is situated slightly behind the middle, and from this point 

 gently diverging till they reach the posterior edge. Surface of the sides of the pronotum and the pleura 

 of meso- and metathorax quite coarsely wrinkled and grooved or covered with irregular raised lines. 

 Tegmina moderately broad, a little longer than the abdomen, with the dorsal portion flattened and 

 separated from the discal field by a decided angle, their apex obliquely truncate. Hind femora extending 

 a trifle beyond the tip of the abdomen, only gently enlarged at the base, and with the lateral apical lobes 

 pointed. Hind tibiae with 11 spines in the outer row. Interspace between the mesosternal lobes broader 

 than long, the sides rounded. 



The upper edge of the lateral lobes of the pronotum provided with a narrow streak of black, which in part 

 crosses to the dorsal surface at the transverse sulcus. There is also a row of irregular black dots along 

 the dorsal portion of each elytron just inside the angle, and a few similar dots on the discal field, although 

 the latter are scarcely visible on account of the dark brown colour of this portion. It is possible that in 

 life this insect has a pale-coloured abdomen, especially below, and that the legs are also somewhat lighter 

 than the head and thorax. There are indications of a greenish tinge on the anterior portion of the sides 

 of both the meso- and metathorax, and it is therefore likely that the species will be found to vary 

 considerably in its general colour, as do many of its allies. "Wings tinged with ferruginous as in 

 0. pagana.
