ASHMEAD : CLASSIFICATION OF THE CHALCID FLIES 451 



the teeth tipped with black ; the first or basal tooth is long, acute, the following 

 triangular, about equal in size. 



Brazil : Chapada, in May. One specimen. 



OCTOSMICRA TRIMACULATA, Sp. nOV. 



Female. — Length 10 mm. Yellowish-red, with a spot on each lateral lobe of meso- 

 notum and at the apex of the scutellum, black. The body of the abdomen is coni- 

 cally pointed, the terminal segment styliform, the sheaths of the ovipositor at apex 

 and the ovipositor, black ; the dorsal segments are stained with brown or blackish 

 marks. The femoral furrow of the mesopleura has a black spot low down, but 

 otherwise, except as noted, the thorax is immaculate. The hind femora are as in 

 0. nigromaculata, except that the teeth, after the first, are not nearly equal in size, 

 the second tooth being small, the eighth tridentate at apex or tricuspidated, so that 

 the femora appear as if ten-dentate. 



Brazil : Corumba in May. One specimen. 



HEPTASMICRA Ashmead, gen. no v. 



The hind femora in this genus are armed with seven large teeth, the second 

 usually reduced in size and sometimes tricuspidate : the abdomen is fusiform or 

 conically produced, rarely ending in a stylus ; while the mandibles in the female are 

 bidentate, in the male tridentate.
