HYMENOPTERA PARASITICA 311 



(6) Toxeuma nigrocyanea, sp. nov. 



?. Length 2 mm. Uniformly blue-black, polished, and without a metallic tinge, 

 under a strong lens exhibiting at the most a feeble alutaceous sculpture ; the anterior 

 tibiae beneath and at apex and all tarsi, except the last joint, are honey-yellow or light 

 brown ; wings subfuliginous, with their basal third and a streak beneath the marginal 

 vein hyaline, the veins being brown. 



The head in the ? is lost and the antennal characteristics cannot be given. The 

 abdomen is conic-ovate as in the previous species [T. nubilipennis). 



$. Length 1*5 to r6 mm. Blue-black, with the tarsi light brown, the flagellum 

 brown-black, the funicle joints submoniliform and subpedunculated, a little wider than 

 long, while the abdomen is oval, depressed, and much shorter than the thorax. 



Hab. Lanai (2000 feet), in January. 



Stictomischus Thomson. 

 1878. StictomiscJms Thomson, Hym. Skand., iv. pp. 220 & 234. 



( I ) Stictomischus haleakalae, sp. nov. 



t. Length 2 '8 mm. Dull bronzed green, shagreened, the sculpture of the middle 

 and lateral lobes of the mesonotum anteriorly transversely wrinkled ; the sides of the 

 thorax and beneath, the legs, except the anterior tarsi which are honey-yellow and the 

 tibial spurs which are whitish, and the abdomen aeneous-black. The antennae are 

 filiform, the scape and pedicel shining black, the flagellum dull, brown-black, pilose, the 

 first joint of the funicle being much the longest joint, a little thicker at apex than at 

 base and about four times as long as thick, while the following joints to the club are 

 subcylindrical, nearly equal in length, hardly thrice as long as thick. The wings are 

 subfuscous, the veins brown, the marginal and postmarginal veins longer than the 

 stigmal vein, the latter ending in a large knob. Abdomen oblong oval, depressed, 

 much shorter than the thorax. 



Hab. Maui : Haleakala (5000 feet), March 20, 1894. 



Subfamily IV. LELAPINAE. 



This group, up to the present time, has been represented by a single genus, Lelaps 

 Haliday, well represented in the West Indies and in South America. 



Dr von Dalla Torre, in his Catalogus Hymenopterorum, V^ol. v. 1898, has 

 unwarrantably changed Lelaps into Laelaps, a name already employed in the Reptilia 

 and the Arachnida. The original spelling of the genus is here retained, and since two 

 new genera allied to it have been recognized in the Hawaiian fauna, I have concluded 

 to give here a synopsis of the genera now known to me.
