54 FAUNA HAWAIIENSIS 



primum postice rubro-marginatum. cT-is clypeus leviter, ?-ae vix emarginatus. 

 Mesonotum subnitidum, distincte punctatum. Propodeum rugosum. Abdominis seg- 

 mentum secundum fortiter elevatum, lateribus subcompressis ; subtus, depressione post 

 costas distincta, minus alta. </?. Long. 7 — 10-5 mm. 



Black, the wings infuscate and with blue iridescence. A median spot behind 

 the antennae, one on either side of the prothorax, nearly united, one or more on the 

 tegulae, one on the mesopleurae, the postscutellum in front, and the hind margin of 

 the basal segment of the abdomen, red. In the ^ the front tibiae usually, sometimes 

 the intermediate, and rarely the posterior are more or less red, as also a longer or 

 shorter line on the scape of the antennae. 



Clypeus of cT dentately-emarginate but not deeply. Head above the antennae 

 closely and rugosely punctured. Mesothorax distinctly punctured, less closely and 

 regularly behind than in front, between these punctures with a distinct minute 

 puncturation, the surface more or less smooth and shining. Propodeum rugose. 

 Abdomen with the basal segment largely punctured ; second very finely and 

 remotely, except towards the apical margin, strongly raised from the base in both 

 sexes, its sides somewhat compressed ; beneath, with the depression distinct, but 

 shallow, rather deeper in the ? than in the j", the segment at the sides not at all 

 strongly raised from the apices of the costae. 



Hab. Molokai mountains (3000 ft.). lao Valley, Maui, 2 ^ not quite typical, 

 having the apical margin of the second abdominal segment red at the sides, and 

 below the average size of the species.

Niger, alis infuscatis, caeruleo-iridescentibus. Caput nigrum, mandibulis rufis. 

 Pronotum rubro-notatum. Abdominis segmentum primum margine apicali late rubro ; 

 secundum utrinque rubro-maculatum. Mesonotum subnitidum, distincte punctatum.

Black, the mandibles red. Prothorax with red markings, the rest of the thorax 

 black. Apical margin of the basal segment of the abdomen with a wide red band, 

 second segment with a red spot on either side. 



Clypeus distincdy dentately-emarginate at the apex (but not deeply) in the c/, 

 less distincdy so in the ?. Head above the antennae more or less shining, very 

 closely and distinctly punctured. Mesothorax and scutellum not coarsely, but some- 

 what deeply and remotely punctured ; propodeum almost smooth, slightly shining, and 

 nearly impunctate. Basal segment of the abdomen hardly shining, with irregular 

 shallow puncturation ; second segment rather abruptly, but not very strongly, raised
