HYMENOPTERA PARASITICA 313 



( I ) Neolelaps hawaiiensis, sp. nov. 

 (Plate VIII. fig. 7, ?.) 



?. Length 6 to 6"2 mm. Head and thorax bronzed green, shagreened, the 

 abdomen metallic brown, the eyes brown. Scape of antennae, the tegulae and the legs, 

 except the coxae, yellow, while the veins of the wings, except the subcostal vein and 

 the knob of the stigmal vein, which are brown, are pallid. 



The antennae are long, the joints of the funicle being long and cylindrical, but 

 gradually shortening to the club, the first joint being not quite five times as long as 

 thick, the last about thrice as long as thick. The abdomen is produced at apex, the 

 7th and 8th segments forming a spike-like process which is nearly as long as the rest of 

 the abdomen. 



Hab. Kauai (high plateau). Taken in August 1894. 



(2) Neolelaps fiavipes, sp. nov. 



%. Length 2-9 mm. Head and thorax bronzed green, shagreened, the abdomen 

 aeneous-black ; scape of antennae, the tegulae, and the legs, except the coxae, brownish- 

 yellow, the flagellum brown. 



The antennae are 13-jointed, with 2 ring-joints, the joints of the flagellum all 

 distincdy fluted, the funicle joints in outline nearly oval, longer than thick. The 

 scutellum is divided by a strong punctate line towards apex and by a punctate line from 

 the postscutellum. The metathorax is produced into a small globose neck at apex, the 

 metanotum being biareolated, the sides fimbriate with white hairs, the spiracles oval. 

 The abdomen is acutely conically produced at apex and is attached by a very short 

 petiole to the under surface of the globose neck of the metathorax, the second segment 

 being large and occupying fully one-third of the whole surface of the abdomen. 



Hab. Kauai : Koholuamo, in April. One ? specimen. 



Mesolelaps, gen. nov. 

 Diflers from all the other genera included here by the shape of the abdomen, which 

 is subglobose or short oval, never conically produced at apex, and by the very large 

 second segment which occupies most of its surface, the following segments being very 

 short and more or less retracted, while the cross-furrow of the scutellum is much nearer 

 the tip than in Lelaps or Neolelaps. 



( 1 ) Mesolelaps cyaneiventris, sp. nov. 

 (Plate VIII. fig. 8, ?.) 

 %. Leno-th 2-8 to 3 mm. Head and thorax variable from a bronzed green to a 

 metallic or blue-green, and both shagreened, with the posterior margin of the mesopleura
