34 FAUNA HAWAIIENSIS 



(7) Odynerits vulcanus. 



Odynertis vtilcamis, Blackburn, P. Manch. Soc. Vol. xxv. (1885-86), p. 152. 



Niger, alis caeruleo-iridescentibus. Clypeus leviter emarginatus vel subtruncatus. 

 Mesonotum cum scutello peropacum, subaequaliter distincte punctatum. Propodeum 

 (plerumque reticulatim) rugosum. Abdominis segmentum secundum (praecipue maris) 

 fortiter elevatum. c/?. Long. 8 — 10 mm. 



Black, the mandibles dark, the wings with blue iridescence. Clypeus with 

 the apex depressed and slightly emarginate, sometimes truncate. Front of the head 

 densely and distinctly punctured. Mesothorax with the surface quite dull, somewhat 

 closely and evenly punctured, posteriorly about the middle the punctures generally 

 are sparser. Scutellum dull and distinctly punctured. Propodeum with rugose 

 sculpture generally reticulate. Abdomen with the basal segment closely and largely 

 punctured ; second segment strongly and abruptly raised from the base, especially 

 in the (/ ; beneath, the depression wide but not deep, so that even at the sides 

 the segment rises not at all strongly from the level of the apices of the costae. 



Hab. Hawaii, widely distributed and not rare. 



(8) Odynenis Iiiloeiisis, sp. nov. 



Praecedenti simillimus, sed mesonoto minus opaco, densius ac grossius punctato, 

 abdominis segmento secundo subtus minus late depresso distinguendus. cT?. Long. 

 7|- — io-| mm. 



Extremely like O. vulcanus but may be known at once by the almost or quite 

 shining surface of the thorax between the punctures. The mesothoracic puncturation 

 is also closer and coarser, and the depression of the second ventral segment evidently 

 less wide. 



Hab. Hawaii, not rare on the windward side of the island, in the forests 

 above Hilo (2000 ft.) and at Olaa. 



(9) Odynerus konanus, sp. nov. 



Niger, alis caeruleo-iridescentibus. Clypeus levissime emarginatus vel truncatus. 

 Mesonotum nitidum, distincte aequaliter punctatum. Propodeum rugosum. Segmentum 

 abdominis secundum elevatum, subtus depressione lata, late costarum apices antice 

 attingente. cf?. Long. 9 — 1 1 mm. 



Black, the wings with blue iridescence. Clypeus depressed at the apex, slightly
