sides above, and reaching clypeal margin below the sides irregular ; mandibles 

 dark reddish in middle ; antennae dark ; mesothorax dullish, not highly polished ; 

 tubercles black, with a fringe of grey hair ; tegulse black, reddish posteriorly ; wings 

 strono-ly reddened ; stigma dusky red, margined with darker ; nervures fuscous ; 

 venter of thorax with shining white hair ; hair on hind tibiae and tarsi reddened 

 anteriorly. 



Male. Length about 6-5 mm. ; more slender, with the usual male characters. 

 Face narrow, with long black hair, and no light markings ; stigma narrower and 

 darker ; tibiae apically, and all the tarsi red ; abdomen darker, even the apical 

 segments suffused with black. This is possibly a different species, but probably 

 belongs here. 



National Park, Q., Dec, 1919, four females, one male {Hacker). Close ($) to 

 E : hamulata Ckll., with the same broad face, but easily distinguished by the much 

 darker legs, only ])artially and very obscurely reddened, if at all. The abdomen 

 also is much darker. The male is remarkable for the entirely black face. 



Exoneura baculifera n. sp. 

 Female. Length somewhat over 6 mm., but smaller than E. rohusta ; black, 

 robust, with the broad abdomen dark chestnut-red, the first two segments mainly 

 black, and a transverse dusky cloud on third ; knees, anterior and middle tibiae 

 apically, and their tarsi, rather dusky-red ; clypeus with a narrow rod-like pale 

 yellow stripe, often subobsolete ; orbits converging below ; antennae dark ; tegulae 

 piceous, reddest behind ; wings strongly brownish, or reddish, stigma and nervures 

 dusky ferruginous ; tubercles dark ; hind tibiae and tarsi with much black hair, 

 shining reddish at apex of tibiae. 



National Park, Q., Dec, 1919, five females {Hacker). Allied to E. angoj)horce 

 obliterata Ckll., but easily separated by the dark legs and abdomen. It is to obliterata 

 whe^t robusta is to hamulata. 



Exoneura excavata n. sp. 

 Pemale. Length about 7-5 mm. ; black, with the abdomen dark chestnut-red, 

 the first segment with a broad blackish suffusion on disc ; anterior knees, tibiae 

 apically, and all the tarsi dark red ; in certain lights the. middle and hind tibiae 

 appear to be bright red above, but this is due to remarkable coppery hair ; the 

 hair on hind tarsi is also red, subappressed ; face broad, excavated and basin-hke, 

 shining (though the clypeus is minutely punctured), wholly black ; labrum convex, 

 dark red ; mandibles reddish ; antennae entirely dark ; mesothorax and scutellum 

 polished ; tubercles black ; hair on under side of thorax pale reddish ; tegulae 

 piceous ; wings strongly reddish ; stigma dusky-red with darker margin, nervures 

 dusky-reddish ; apical part of abdomen with short red hair. 



National Park, Q., Dec, 1919, one female {Hacker). A remarkable species, 

 easily known by the black excavated face.
