134 Ml'. R. E. Turner on some new or 



Antennae scarcely longer than the head is broad, the scape 

 stout and about lialf as lonf; as the flajjellum. Pronotuin 

 broad, nf-arly twice as broad as long, narrower than the head, 

 the median line rather broadly raised, the sides subconcave, 

 tlie depressions not reaching the posterior margin. Median 

 segment and scutelluni of almost equal length, combined 

 scarcely longer than the pronotum, the whole thorax sliining, 

 with a ^QVf fine scattered punctures. Abdomen broader than 

 the thorax and much longer than the head, thorax, and median 

 segment combined ; the first and second segments depressed 

 on the apical portion, narrowly at the sides, much more 

 broadly in the middle, the anterior portion smooth and shining, 

 the depressed portion opaque and very finely shagreened ; 

 segments 3-5 smooth and shining, very narrowly and 

 shallowly depressed on the apical margin; the ventral seg- 

 ments sparsely punctured with a smooth depressed space, 

 broadest in the middle, at the apex of segments 2-4. Pygi- 

 dium oblique, twice as long as broad, the sides nearly parallel, 

 the hypopygium projecting beyond the epipygium, having 

 an exposed surface nearly half as long as tlie epipygium, 

 rounded at the apex ; the epipygium truncate at the apex, 

 with a long whitish seta on each side near the base. Tarsal 

 ungues bidentate. 



Fuscous black ; the head and legs dark fusco-ferruginous ; 

 the pygidium and antennse fusco-ferruginous ; the depressed 

 apical portion of the two basal dorsal segments and of ventral 

 segments 2-4 pale testaceous. 



Length 8-9 mm. 



Described from two specimens, one of which is apparently 

 not quite mature and has the abdomen entirely ferruginous- 

 brown. 



Hah. Santa Rosa, Mendoza (A. C. Jensen-Iiaarup) . 



This species somewhat resembles Ornejjetes albonotata, 

 Andr^, in the form of the pronotum, but otherwise is nearer 

 to Pseudelaphioptera jlavomaculata, Andre, except in the 

 longer and narrower pygidium. It may prove to be the 

 female of P. rolU'i^ Turn. 



Elaphroptera promissa, sp. n. 



? . Head subrectangular, strongly rounded at the posterior 

 angles, more than twice as broad as the pronotum, nearly 

 half as broad again as long, thick and scarcely concave above ; 

 the eyes small and broadly ovate ; the front divided by a 

 longitudinal sulcus. Pronotum small, broader than long, 

 scutellum small and narrow, rounded posteriorly ; the median
