44 PROCEEDINGS OF THE NATIONAL MUSEUM. vol. 51. 



STENOMESIOIDEA MELLEA, new species. 



Female. — Length, 2.50 mm. 



Uniformly golden yellow, the funicle and club black, the venation 

 yellow, the forewing stained yellow from base out to the end of the 

 venation. Funicle 1 much the longest, nearly twice longer than 

 wide, 4 barely longer than wide, subequal to club 1; club 2 conical 

 and longer than 1, acute, without a terminal nipple. Pedicel not 

 quite as long as funicle 4. Body with delicate scaly sculpture. 



Type. — Cat. No. 12735, U.S.N.M., two females on tags (forewing, 

 caudal tibiae, and an antenna on a slide). These specimens are 

 labeled " Stenomesoidea mellea Aslmi.," an undescribed species, and 

 "3436°.26/784." 



SYMPIESOMORPHELLEUS NIGRICEPS, new species. 



Female. — Belongs to the Ophelinini and in my table to the Austra- 

 lian genera runs to Sympiesomorphelleus but the club is apparently 

 3-jointed, the third joint nipple-like yet not articulated. Axillae not 

 advanced. 



Length, 2.50 mm. 



Deep orange yellow^, the head, antennae, prothorax, scutum, parap- 

 sidcs except laterad, axillae except caudal and lateral margins, mar- 

 gins of abdomen very narrowly and a median stripe down dorsum of 

 abdomen commencing a little out from base, gradually narrowing to 

 apex, black. Tip of ovipositor valves black. The very long-sagittate 

 mesal marking on abdomen is connected narrowly with the base. 

 Head finely scaly (except the middle of the face), the thorax more 

 coarsely so (except the scutellum, postscuteUum, and propodeum, 

 which are glabrous, the abdomen slightly scaly). Propodeum with 

 a delicate median carina and no others, the spiracles small. Pedicel 

 a little longer than wide at apex, shorter than funicle 4. which is a 

 little longer than wide; funicle 1 nearly twice longer than wide; 

 club 1 slightly shorter than funicle 4; club 2 shorter, the apparent 3 

 very small. Venation as in Stenomesioidea but the marginal vein 

 distinctly longer 



From one female in the United States National Museum labeled 

 "College Station, Texas. September, Banks." 



Type.— Cdit. No. 19594, U.S.N.M., the female on a tag; the hind 

 tibiae, forewing, and an antenna on a slide. 



The grooves on the scutellum are just within the two bristles on 

 each side. 



Genus CIRROSPILOIDEUS Ashmead. 



The hind tibiae bear two rather long, slender spurs, so the genus 

 belongs to the Ophelinini and is the same as my Sympiesomorphel- 

 leus. The mandibles of the genotype are 8-dentate. The tenninal
