4. Sitalces ovatipennis, sp. n. 



A rather small, dark-coloured insect above, with short oval tegmina. Hind tibia? 6-spined in outer row. 

 Body sparsely hirsute throughout. 



Head rather wider than the front edge of the pronotuni, the occiput of $ at least slightly ascending ; face 

 greatly ( d 1 ) or moderately ( $ ) oblique ; eyes large and prominent in the S , a little less so in the $ ; 

 vertex between the eyes of <$ very narrow, only about one-half as wide as the frontal costa between the 

 base of the antennas, that of the $ a little wider ; fastigium somewhat depressed, shallowly sulcate, slightly 

 broader than long. Frontal costa prominent above the ocellus, plane, with a few coarse punctures at its 

 upper extremity ; at the ocellus and below less prominent, below the ocellus suddenly narrowed to the 

 transverse facial groove, from which point it broadens and continues to the clypeus, at the ocellus and 

 below gently sulcate. Antennas somewhat coarse, filiform, in the $ a trifle longer, in the $ less, than 

 the head and pronotum combined. Pronotum slightly widening behind, coarsely punctate, much more 

 closely so on the hind lobe : the transverse sulci profound, the posterior one alone severing the median 

 carina; anterior margin rounded, with the centre shallowly, arcuately emarginate, hind margin angu- 

 lately emarginate. Dorsum of meso- and metathorax, along with that of the first abdominal segment, 

 profusely and coarsely punctate ( J ), or sparsely and shallowly so ( $ ). Tegmina small, short, oval, 

 reaching to about the middle of the metathorax. Auditory apparatus almost entirely obliterated. Hind 

 femora somewhat robust, in the $ about reaching the tip of the abdomen, in the S extending beyond it 

 one-third their length. Prosternal spine broadly pyramidal, the apex acuminate. Last ventral segment of 

 S -abdomen short, the apex entire, the outer or apical third provided with a, strong median carina ; supra- 

 anal plate elongate-triangular, with coarse elevated borders, the outer half bent downwards, the transverse 

 ridge thus formed narrowly sulcate. Cerci little longer than the supra-anal plate, tapering and curved 

 inwards on the distal half. 



General colour of head, thorax, and base of abdomen dark brown, almost black, on the pleura and abdomen 

 apically brownish-olive, below greenish-yellow ; legs olivaceous, the tibiae and tarsi deep bottle-green ; face, 

 lower edges of pronotum, and a line on the pleura flavous. The face above the base of the antennas is 

 provided with a shiny black band running from eye to eye and taking in the apex of the fastigium ; a 

 second black mark occurs on the occiput just back of the centre of the upper edge of the eyes. In the $ 

 there is a yellowish border to each side of the occiput that continues upon the lateral edges of the disc of 

 the pronotum and upper half of the tegmina, while a third line of this colour follows the median carina 

 of the pronotum and continues over the middle of the abdomen nearly or quite to its tip. In the <$ the
