HYMENOPTERA 6i 



but quite distinctly punctured, the surface dull. Abdomen with the surface shining, 

 the basal segment depressed along its apical margin, with shallow puncturation ; 

 second segment evidently raised from its base, especially in the i ; beneath with the 

 costae very short, the depression narrow and very light, sometimes hardly evident. 

 Hab. Kona and Kau districts of Hawaii (4000 ft.). 



(60) Odyneriis egens, sp. nov. 



Niger, alls infuscatis, caeruleo-iridescentibus, mandibulis et apice clypei rubris, 

 abdomine toto nigro. Caput cum mesonoto peropacum, vix evidenter punctatum. 

 Abdominis segmentum 2 ventrale costis fortibus et brevissimis, post has subplanum, 

 depressione nulla. Long. cT 8 mm. 



Black, the wings with blue iridescence, the apex of the clypeus and the man- 

 dibles red. Thorax and abdomen black. On the second ventral segment of the 

 latter a faint reddish tint can be seen in a strong light. Head and thorax with the 

 surface finely roughened, dull, the puncturation almost obsolete. With a very strong 

 lens both systems of the thoracic punctures can be seen to be present, but very 

 feebly impressed ; the minute ones are rather less nearly obsolete, and form the chief 

 part of the puncturation. The mesothorax in front has a smooth median line, ex- 

 tending back about one-third of its whole length. The second segment of the 

 abdomen is very little raised from the base ; beneath, the costae are short but strong, 

 not so long as the basal part of the segment, which is shining ; beyond the costae 

 there is no evident depression, but the surface is nearly flat.

(6 1 ) Odyneriis nesiotes, sp. nov. 



Niger, alis infuscatis, caeruleo-iridescentibus, abdominis segmentorum 2 basalium 

 marginibus postice albo-marginatis. Mesonotum subnitidum grosse, fortiter, denseque 

 punctatum. Abdominis segmentum 2 ventrale sulco nitido, costis fere obsoletis, de- 

 pressione lineari, minus distincta. t/?. Long. 7 '5 — 9 mm. 



Black, the wings with blue iridescence. Basal segment of the abdomen with 

 a narrow, and the second with a wide, cream-coloured apical band. Head above the 

 antennae, and the mesothorax, very densely, coarsely and rugosely punctured, the 

 surface between the punctures shining. Propodeum with evident but shallow punc- 

 turation. Abdomen with the basal segment densely punctured ; second segment be- 

 neath, with the sulcature for the most part smooth, with only traces of the costae at 

 its base, the depression represented by a faintly impressed line. 



Hab. Mountains of Kauai, near Makaweli (2000 — 3000 ft.).
