 Descriptions of New Hawaiian Odynerus. 



BY AVALTEK M. GTFFAKD. 



()dij)\cvus ■)no}}a.s Perk. var. aeneiis var. nov. 

 Black, coloration of first and second segments of the abdomen 

 very variable from almost all black to having the first and second 

 segments of the abdomen almost all red or else spotted red at the 

 sides. The structure of the second ventral segment is also very vari- 

 able, some examples indicating a very light but distinct depression 

 whilst others show none at all or at most this character is repre- 

 sented by a very faint and interrupted line. The head and thorax 

 are very finely, sparsely and shallowly punctured, the median im- 

 pressed line in all the examples examined continuing through the 

 post scutellum. The tibiae and tarsi have a distinctly fusco-testa- 

 ceous appearance, and the wings are very shining fuscous, having in 

 certain aspects a very bronzy iridescence. 



Ilab. — Above ]\ranele, Lanai, approximately 1000 feet 

 elevation, flying over wild "ilima" flowers. 12 males and 3 

 females, Febrnary and May, 1908 (Giffard). Xot uncom- 

 mon. Variety type in author's colle^'tion. 



Obs. — Undoubtedly only a variety or insular form of 0. 

 n onas Perk, of Molokai. The remarks expressed by me in 

 thf Proe. Haw. Ent. Soc., IT, No 5, p. 231, lead me to sepa- 

 rate this Lanai wasp as a variety only. 



Odynerus l-auensls sp. nov. 



Extremely like the description of the Molokai 0. monas Perk.* 

 in form and sculpture, the red color markings of the abdomen being 

 also very variable and in some instances almost all black. It differs 

 from that species in having the wings darkly infuscate and a deep 

 violaceous blue iridescence; mandibles mostly red; basal segment of 

 the abdomen laterally more evenly curved from the petiole (not so 

 abrupt as in 0. monas) and the ventral depression of the second 

 segment somewhat wide and deep, meeting the apices of the costae 

 obliquely. Male and female, length 7-8 mm. 



Ilab. — Xear Honuapo, Kan, Island of Hawaii, at a low 

 elevation; flying over scrubby and stunted growths on ancient 

 a-a lava flows. 10 males and 1 female. May and December, 

 1910; April, 1911 (Giffard). Types in author's collection. 



Obs. — This species is evidently scarce, but few specimens 

 being captured after repeated visits to the locality during 

 1910 to 1914; I have never met with it elsewhere on the Isl-
