First vein bristly on its apical two-thirds; face on lower half of sides 

 bare; proboscis scarcely longer than height of head; apical cell ending at 

 wing tip barely open or slightly closed; eyes bare; frontal vitta opaque; 

 palpi subcylindrical; penultimate joint of arista slightly longer than broad; 

 sides of face at narrowest point not nearly one-third as wide as median 

 depression; head at vibrissae shorter than at root of antennae; horizontal 

 diameter of occiput above neck less than one-half length of eye. With one 

 or more frontal bristles below base of antennae. Female with one or two 

 pairs of orbitals. Female with second segment of the abdomen prolonged 

 ventrally into a long setigerous tubercle, quite twice as deep as the fourth 

 abdominal segment. 



Neocelatoria ferox n. sp. 



Minute, blackish, wings broad, hyaline, Eyes large, occupying nearly 

 two-thirds of the head, each fully as wide as front. Front cinereous, sides 

 nearly parallel. Vertex slightly black. Frontal vitta dark brown, nearh 

 black, occupying about one-third of the front immediately over root of an- 

 tennae, gradually widening towards vertex where it occupies fully one-half 

 of the'width of front. Entire face including depression cinereous; sides at 

 narrowest part not more than one-tenth as wide as depression; antennae 

 black, slightly cinereous, almost or quite as long as face. Third joint at 

 least five times as long as second; artista; thickened to the middle; second 

 joint slightly longer than broad; post vertical and ocellar bristles strong. 

 Usually two pairs of orbital bristles (in female), frontal bristles descending 

 nearly to tip of second joint; proboscis short, fleshy, black; palpi yellow 

 Beard and hairs of lower occiput white; vibrissae on oral margin; oral cavity 

 large, occupying the entire width of face. Facial ridges bristly on more 

 . tha"n lower half; thorax black, humeri and median vitta thinly gray pollin- 

 ose to the transverse suture ; posterior to this nearly bare. Abdomen black 

 shining, somewhat laterally compressed; bases of second, third and fourth 

 segments thinly gray pollinose. First segment without marginals; second 

 segment bearing marginals only; third segment bearing a pair of small dis- 

 cals and marginals; fourth with a marginal row only. Post sutural bristles 

 three; sternopleurals three with some coarse hairs. Scutellum black 

 ing three pairs of long marginals, the apical pair the smallest. Abdomen 

 viewed from the side showing a deep, compressed, setigerous prolongation 

 of the second segment, the lower end of which projects considerably below 

 the level of the bottom of hind coxa?. Ovipositor and piercer black, strong- 

 ly chitinized, slightly compressed laterally, curved forward with its 

 ensheathed in the prolongation .of the second segment. Legs rather stout, 

 black; middle tibise with a single strong bristle on the front side near mid-
