36 FAUNA HAWAIIENSIS 



and closely punctured ; the second raised from the base above ; beneath, the depression 

 is narrow and hardly meets the apices of the costae, the segment at the sides being 

 abruptly raised from these to about the height of its basal portion. 



Hab. Mountains of Kauai. Halemanu and elsewhere on the high plateau. 



(12) Ody nevus Iencozo7iias, sp. nov. 



Praecedenti simillimus, et eodem colore, sed mesonoto magis nitido, propodeo 

 laevi (punctato), et abdominis segmento secundo fortius et abruptius elevato, bene 

 distinctus. <}%. Long. 8 — 10 mm. 



Very similar to the preceding in form and colour. 



The surface of the head in front, the mesothorax and scutellum, are very smooth 

 and shining between the punctures, the system of minute punctures between the larger 

 ones on the mesothorax being hardly observable, instead of very distinct. The pro- 

 podeum is much smoother, with shallow but distinct punctures, and the second segment 

 of the abdomen is more strongly and abruptly raised from the base. 



Hab. Kauai (2000 — 3000ft.). Found also on the high plateau. 



(13) Odynerus eludens, sp. nov. 



Praecedenti simillimus, margine apicali segmenti abdominis primi angustissime 

 pallido. Mesonotum nitidum fortiter punctatum, interstitiis evidenter minutissime 

 punctatis. Propodeum laeve, antice sparsim subobsolete punctatum, concavitate fere 

 impunctata. Abdominis segmentum primum (a latere visum) a basi usque ad marginem 

 apicalem aequaliter curvatum. ?. Long. 9*5 mm. 



Allied to the two preceding species but with the basal segment of the abdomen 

 (viewed laterally) more evenly and gradually curved from the petiole — not abrupt in 

 front. The mesothorax is smooth and shining between the punctures as in O. leitco- 

 zonias, but the interstices have the minute system of punctures very evident. The 

 propodeum in front is somewhat shining, with some very feebly impressed punctures ; 

 the concavity is smooth and almost impunctate. The pale apical band of the basal 

 segment of the abdomen is unusually narrow ; the second segment is considerably, 

 but by no means abruptly, raised from the base, the highest point attained (as seen in 

 lateral view) being rather more than one-third of the whole length of the segment from 

 the base. Beneath, the depression somewhat narrow, deeper than in the two preceding 

 species. 



Hab. Halemanu, Kauai (4000ft.). i?.
