sulcus; truncation of metathorax with a deep longitudiaal groove; 

 tegul?e shining, red-brown, not punclured; wings rather dusky, 

 especially at tips, minutely but conspicuously hairy ; nervures and 

 stigma dark brown, second submarginal cell narrow, legs dark red- 

 brown, anterior tibite and tarsi ferruginous; abdomen with a de- 

 cided constriction between first and second segments; first segment 

 only moderately narrowed at base; first two segments piceous, first 

 with very large close punctures, second with large and small punc- 

 tures on its anterior half, extreme base greenish; remaining seg- 

 ments greenish, pruinose with a short pubescence, their hind margins 

 testaceous; antennie dark, flagellum ferruginous beneath at apex. 



d. — Length about 6 mm. ; similar to 9, but narrower, espe- 

 cially the abdomen ; antennse much longer, flagellum dark at 

 apex; anterior femora, tibiae and tarsi entirely bright ferruginous; 

 second abdominal segment with large punctures like first; fourth 

 ventral abdominal segment emarginate. 



Hab. — Chapada; 4cJ*, 1?; January, December. 

 Corynura (Corynuropsis) sublata n. sp. 



9. — Length about 8 mm., more robust than C. darwini, with 

 the first abdominal segment broader; eyes somewhat more parallel; 

 mesothorax more decidedly purplish ; wings perhaps a little 

 browner; supraclypeal area more or less coppery red. 



Hub. — Chapada, 1 9 ; December. Perhaps only a variety of 

 the last, but it is larger and seems distinct. The pleura is rough- 

 ened, and has also sparse shallow punctures. In C. darwini the 

 second abdominal segment is conspicuously wider than the first, 

 widening from its base to iis nind margin; in C. sublata the second 

 segment has nearly parallel sides, and is very little wider than the 

 first. 

 AugocMora calli chroma n. sp. 



?. — Length about 5 mm.; head and thorax brilliant golden 

 green; legs honey-color; abdomen pale ferruginous with dark-brown 

 blotches, small at sides of first segment, large at sides of second, 

 covering all of third except a variable patch on disk, and also 

 occupying the whole of fourth and fifth segments, so that the hind 

 portion of the abdomen is dark brown; at each extreme side of 

 segments 2 to 5, quite at the base, is a clear yellow triangle, with its 

 apex directed mesad; clijpeus icith a broad apical yellow band, which 

 sends a projection upward in the middle line; mandibles yellow.
