37. IW. serra % .—Length 11 mm.— Sniall, black, the pubescence mostly 

 black, white on clypeiis ; head and thorax, except metathorax, closely, confluently 

 punctured. Eyes ovate, convex, prominent. Scutellum convex, the lateral teeth 

 prominent, obtuse; the metathorax rather coarsely reticulated, the reticulations 

 larger at base, the pubescence long, scattered and pale; a sharp spine beneath 

 teguhB. Wings uniformly fuscous, except a pale streak in second submarginal 

 cell and a spot beneath its apex; marginal cell as long as second and third sub- 

 marginal cells combined, broadly rounded at tip, and not extending beyond 

 apex of third submarginal, which is complete and much narrowed beneath; sec- 

 ond submarginal elongate, receiving the recurrent nervure before the middle, 

 the first and second tranverso-cubital nervures widely separated on marginal. 

 Legs nigro-piceous, the pubescence brown or black ; calcaria testaceous. Abdo- 

 men slender, the pubescence black, except on first segment and a few scattered 

 hairs at base of second where it is whitish ; first segment elongate, nodose and 

 constricted at apex, punctured ; second and following segments very minutely 

 punctured, somewhat shining; venter polished, second segment sparsely and 

 finely punctured, the pubescence black, some scattered pale hairs on first and 

 base of second segments. 



Chapada. One specimen. Resembles tapera somewhat, but 

 smaller, the tubercle beneath tegulse acute, the abdomen less strongly 

 punctured, and the neuration of anterior wings different. 



38 I»I. viana ^ .-Length 10-15 mm.-Black, the pubescence black; head 

 and thorax, except metathorax, closely, confluently punctured. Head small, 

 transverse; eyes ovate, very convex. Scutellum convex, with a central shining 

 tubercle lateral teeth compressed, not prominelit; metathorax coarsely reticu- 

 lated depressed and declivous posteriorly, clothed with long pale pubescence; 

 an obtuse tubercle beneath tegulie. A large spot on vertex between the eyes, a 

 broad baud on apex of first abdominal segment, basal corners of second segment, 

 and a band, interrupted on disk above, occupying the third, and narrow apical 

 margin of second segment, clothed with dense, more or less appressed, and inter- 

 spersed with long, whitish pubescence; some pale hair also on clypeus. Wings 

 fuscous with more or less of base and a large spot about middle of anterior pair, 

 subhyaiine; three complete submarginal cells; marginal truncate at tip, scarcely 

 longer than second submarginal and not reaching to apex of third submarginal, 

 which latter is scarcely narrowed beneath ; second submarginal cell receiving 

 the recurrent nervure before the middle, the first and second transverso-cubital 

 nervures approximate on marginal. Legs black, with black pubescence, that on 

 coxaj and femora beneath sparse, long and pale ; calcaria testaceous. Abdomen 

 with first segment transversely nodose and constricted at apex, the second and 

 following segments closely and finely punctured, somewhat shining; the venter 

 polished, deeply and sparsely punctured ; second segment without a discal fovea, 

 somewhat pinched at extreme base. 



Chapada. One specimen, probably only a variety, has no patch 

 of white pubescence on vertex, and the calcaria are white.
