.S FAUNA HAWAIIENSIS 



o 



apices fortiter dilatatis, et externe fortiter depressis, bene distinctus. </?. Long. 

 9f— II mm. (Plate I. fig. 19.) 



Extremely like the preceding in general appearance. Male with the head, above 

 the antennae, more finely and shallowly punctured, as likewise the mesothorax and 

 scutellum. The propodeum is much less rugose ; its concavity almost smooth, except 

 for the surface rugulosity. Basal segment of the abdomen with the dorsal and 

 anterior faces meeting less sharply, and less coarsely and closely punctured. Female 

 with the head and thorax evidently more finely punctured, and the surface of the 

 latter dull, or almost dull, between the punctures. The posterior concavity of the 

 propodeum is smoother, and the basal segment of the abdomen more finely punctured. 

 The </ is further distinct from any other species by the strongly and suddenly dilated 

 apex of the hind tibiae, the dilated portion outwardly being deeply concave. 



Hab. Mountains of Kauai (3000 ft.). Not a common species. 



(17) Odyneriis conifer, sp. nov. 



Niger, abdomine fasciis duabus albidis ornato. Mesonotum nitidum sparsim subtilius 

 punctatum. Propodeum rugoso-punctatum. Abdominis segmentum primum supra 

 fortiter transversum, antice truncatum, parte antica parti dorsali acute occurrente ; 

 segmentum secundum acute conicum, subtus costis longis, depressione nulla. ?. 

 Long. 9 mm. 



Head closely punctured. Mesothorax smooth and shining, somewhat finely punc- 

 tured, remotely and irregularly on the posterior half. Between these punctures the 

 minute system of puncturation is very distinct. Propodeum with shallow and somewhat 

 rugose puncturation. Abdomen with the basal segment strongly transverse above, 

 depressed, and distinctly punctured, sharply truncate in front ; second segment strongly 

 raised into a sharp cone, beneath the middle costae very long, and no depression beyond 

 their apices. 



Hab. Kauai, on the high plateau. A very remarkable and rare species, of 

 which only i ? was taken. 



(18) Odynerus kauaiensis, sp. nov. 



Niger, fasciis duabus albidis ornatus. Mesonotum densissime grosse punctatum. 

 Propodeum fortiter rugoso-punctatum. Abdominis segmentum primum ad basim 

 puncturatione grossissima rugosum ; secundum haud elevatum ; subtus, costis longis ; 

 post has triangulariter deplanatum, vix depressum. c/?. Long. 8 — 10 mm. 



Apex of clypeus very slightly emarginate or truncate. Mesothorax and scutellum 

 coarsely and closely punctured, the surface between the punctures shining. Propodeum
