656 FAUNA HAWAIIENSIS 



Pachyneuron Walk. 

 Pachyneuron spp. 

 Two or more species of this or allied genera are parasitic on species known to be 

 of foreign origin. 

 Hab. Oahu. 



Subfam. SPALANGIINAE. 



Spalangia Latr. 

 ( I ) Spalangia canieroni, sp. nov. 



Female : Aeneous black, the abdomen deep black or blue-black, the tarsi yellow, 

 dark at the tips. Head elongate, coarsely punctate, the punctures well separated from 

 one another, the eyes with erect white hairs, longer than is usual on these organs. 

 There is an elongate smooth median space at the bottom of the depression above the 

 insertion of the antennae. Antennae with the second joint or pedicel elongate, very 

 much longer than, but hardly twice as long as the first joint of the funicle, four terminal 

 joints of the funicle quadrate, club nearly as long as the three preceding joints. 

 Pronotum very densely rugose-punctate in front and at the sides between which is 

 a smooth, more or less triangular, area, with at most a few punctures, this area bounded 

 behind by a transverse costate line, the apical margin behind the line smooth. 

 Mesonotum with a smooth median line, and a densely punctate area on each side of 

 this ; the parapsides marked out by a costate or punctate furrow, the scapulae bearing 

 some fine punctures ; axillae smooth and shining, like the scutellum, and separated 

 from this by costate lines and both impunctate or nearly, the scutellum having a trans- 

 verse costate line in front of the hind margin and the suture between it and the 

 postscutellum is costate. Propodeum very smooth and shining, with a median narrow 

 costate channel, divided by a longitudinal raised line, and punctate around its margins ; 

 the pleura marked off by a costate suture, very densely and finely punctured below, but 

 smoother near the suture. Wings clear hyaline, neuration brownish. Abdominal 

 pedicel with about half a dozen raised longitudinal lines, the other segments very smooth, 

 the fourth the largest, the third emarginate posteriorly, the apical ones with pale hairs. 

 Length about 3 mm. 



Male very like the female, but the head is shorter, the pedicel of the antennae is 

 minute, hardly longer than wide, much shorter than the first funicle joint, which is much 

 longer than the following ; the other funicle joints longer than in the female, being 

 longer than wide. Length 3 mm. but much smaller examples occur. This is probably 

 the species referred to 5". hirta by Cameron. 



Distinguished at once from 5. Iiirta Hal. by the long second antennal joint in the 

 female. 



Hab. Oahu, Hawaii, Molokai and no doubt all the islands.
