HYMENOPTERA PARASITICA 285 



(3) Scleroderma kaalae, sp. nov. 



%. Length 2 to 2'8 mm. Castaneous, the head and scutellum black or brown- 

 black ; scape, pedicel, legs and first abdominal segment beneath yellowish, the femora 

 and sometimes the tibiae with a decided rufous tinge. The head and the thorax appear 

 smooth but under a strong lens exhibit a fine delicate reticulate sculpture. The head is 

 less than one and a half times as long as wide, with a brownish tinge beneath. The 

 mesonotum is long, about twice as long as the scutellum, slightly narrowed and rounded 

 before. The metathorax is widened posteriorly, being at least one-half wider at apex 

 than at base, the sides and apex abrupdy truncate. The abdomen is elongate, sub- 

 cylindrical, twice longer than the thorax, smooth and shining, with the apices of the 

 segments i to 5 and the terminal segments flavo-testaceous. 



Hab. Oahu : Kaala Mts. (3000 feet), in December, 1892. One ? specimen. 



(4) Scleroderma laiiaiense, sp. nov. 



%. Length 3 mm. Elongate, pale castaneous ; scape, pedicel and legs yellowish, 

 the flagellum light brown ; apices of the abdominal segments more or less yellow. The 

 head is less elongate than usual, being nearly quadrate or only a little longer than wide. 

 The scape of the antennae is longer than half the length of the flagellum and slightly 

 curved, the pedicel being a little longer than wide, while the joints of the flagellum, 

 except the last, are transverse, the basal joints smaller, the last joint oblong, a little 

 longer than the pedicel. 



Hab. Lanai (3000 feet). One % taken in January, 1894. 



(5) Scleroderma nigriventre, sp. nov. 



%. Length i'8 mm. Head, thorax and first segment of abdomen beneath castane- 

 ous ; abdomen black, longer than the head and thorax united, with the apices of dorsal 

 segments 3 to 5 narrowly yellowish ; legs reddish-brown, the incisions of the joints, 

 the anterior tibiae, the tips of the middle and the hind tibiae, and all tarsi, yellow. 

 Antennae yellow (broken off at tips), the first three or four joints of the flagellum 

 minute, wider than long. The head is oblong, about one and a half times as long as 

 wide, the eyes oval, black. The mesonotum is fully twice as long as the scutellum, 

 while the metathorax is only a little longer than wide and only slightly wider at apex 

 than at base. 



One % specimen taken in January, 1894. Allied to S. lanaiense, but smaller, 

 differently coloured and readily separated by the shape of the head and the metathorax. 



Hab. Lanai (2000 feet).
