Subfiunily Perilampin.e. 



ELATHS Walker. 

 Klatus iiiisyinbrii sp. n. 



% . — Lengtli 2.2 nun. Hesul and thorax bright cnjireous. Abdomen teneous- 

 black ; scape and legs metallic, the knees, anterior tibije, tips of middle and pos- 

 terior tibiae and all tarsi, except last joint, brownish yellow; flagellum filiform, 

 brown-black, pubescent, the joints transverse. The head and thorax are nearly 

 smooth, impunctate, but with a very delicate, transverse striation ; scapulae poste- 

 riorly and the axillae smooth, the metathorax and petiole shagreened or minutely 

 shagreened with a delicate median carina. The petiole is two and a half times 

 as long as thick, the body of abdomen triangulated as in Perilampm. and appar- 

 ently composed of only two segments, the third being hardly visible, the others 

 retracted. Wings hyaline, the veins yellowish or brownish yellow, the stigmal 

 and postmarginal veins very short, scarcely one-fifth the length of the marginal. 



Hub. — Las Cruces, New Mex. 



Described from one % specimen taken by Prof. T. D. A. Cockerell 

 and confused with several specimens of a genuine Perilampus. 



This is a most interesting addition to our fauna, and an examina- 

 tion. of this genus shows that the PeriUimpinje have strong affinities 

 with the Miscogasterinie. 



Subfamily p]rRYTOMiNvE. 



ELTRYTO.nA Illiger. 

 Eiirytoiiia tylodoritisttif^ sp. n. 



9. — Length 3..")-4 mm. Black, clothed with sparse, whitish hairs; anterior 

 femora beneath and at tips and their tibiae, knees of middle and hind legs and 

 tips of their tibiae, and all tarsi, honey-yellow; funicle fi-jointed, the fii-st joint 

 the longest about two and a half times as long as thick, or more than twice as 

 long as the pedicel, the second and following joints suboqual, twice as long as 

 thick. Wings hyaline, the veins light brown, the marginal vein not quite twice 

 as long as the stigmal with its knob, the postmarginal a little longer than the 

 stigmal. Abdomen conic-ovate, compressed, a little longer than the head and 

 thorax united smooth and highly polished, except as mentioned below ; the petiole 

 is very short, rugose, the second segment is as long as the third and fourth united, 

 the third and fourth being sul)equal. the fifth is the longest .segment, and while 

 dorsally it is only a little longer than the second, yet ventrally it is much longer, 

 the sixtli is a little shorter than the ti)ird, or about half the length of the seventh ; 

 the fifth segment is closely, microscopically punctate at sides and beneath, while 

 the segments 7 and 8 are finely sliagreened, subopaciue. and sparsely beset with 

 whitish hairs. 



% . Length '.i mm. Agrees with the 9 , except in the usual sexual ditferences : 

 The rtagellum is about five times as long as the scape, the latter dilated beneath, 

 and not longer than the pedicel and first funicular joint united ; funicle 5-jointed, 

 each jo.nt deeply excised and pedicellate at apex, the joints very gradually de- 

 creasing in thickness from base, the dilated portion of each joint from two and 

 a half to three times as long as thick, with double whorls of long white hairs, the 

 pedicellate iKirtion of the joints increasing successively in length, the first joint
