Habitat. — Sapucay, Paragua}^, 2 females (Coll. L. Bruner); a num- 

 ber of specimens of both .sexe.s (Coll. U. S. Nat. jNIiis.). 



In size and general appearance this insect reminds one very much of 

 a representative of Scotnssa, but the form of the ovipositor in the 

 female and the cerci of the male are abnormal for that genus and come 

 much nearer to those of Leiofettir.

Hah/tat. — Luque. Paraguay (Giglio-Tos). Not represented in the 

 Paraguayan collections studied. It occurs also in Argentina as far 

 south as the southern part of the province of Santa Fe. 



SCOTUSSA RUBRIPES, new species. 



General color olive-green, becoming rufous on disk of pronotum 

 and on the tegmina; below greenish yellow. Cheeks and lower half 

 of lateral lobes of pronotum pale greenish yellow. The latter, 

 together with sides of head back of ej'es, i)iceous; this piceous band 

 bordered above bj^ a narrow one of testaceous, which gives to the 

 insect a bivittate appearance, and at first glance suggests a species of 

 Melaiioplus or Dlckroplus., to which the present genus is closely 

 related, but from which it is readily separated b}' the structure of the 

 upper valves of the female ovipositor, which are unusually long, 

 straight, and slender. Hind tibiii^ and tarsi bright coral-red. 



Head about as wide as front edge of thorax, the face rather oblique 

 viewed from the side, the occiput not elevated; width of vertex about 

 two-thirds the shortest diameter of one of the ej^es, fastigium gentlv 

 depressed, sulcate, the well-detined bounding walls meeting in front 

 at a right angle; frontal costa broad, narrowed to one-half its width 

 at ocellus a))ove where it is separated from the vertex b}^ the meeting 

 of the carinas that bound the sulcus, reaching the clypeus, not sulcate; 

 eyes not prominent, about as long as the cheeks below them, slightly 

 pointed above, straight in front; antenna^, liliform, a])out as long as 

 head and pronotum together. Pronotum minus lateral carina^, with 

 the anterior lobe cylindrical, the hind lobe slightly enlarging posteri- 

 orly, about two-thirds the length of the front one, transverse sulci 

 dim, posterior edge broadly rounded or sul)angulate, surface of hind 

 lobe profusely but shallowl}" punctate, of anterior one smoother. 

 Tegmina and wings complete, reaching slightly bej'ond apex of hind 

 femora and ovipositor, the tip rounded, intercalar}' vein well-detined, 

 cross-veins and veinlets few except on basal fourth, where thev are 

 "numerous and irregular, giving the member a granular appearance. 

 Hind femora moderately robust, not quite reaching the apex of uj)per 

 valves of ovipositor; hind tibia; with 8 spines in outer row. Proster-
