 261-62, fig. 12. 



This is a distinctive species, fore wings generally infuscated 

 beneath the marginal vein; in tag-mounted specimens, the abdomen 

 shrinks in a characteristic manner, appearing plainly smaller than 

 the thorax, spatulate in shape; also, in tag mounts the thorax 

 appears wider than usual. The coloration is also distinctive. 



Female. — In general, head, mesoscutum, and parapsides ferrugino- 

 testaceous. Axillae and scutellum dark brown or testaceous with 

 some fuscous. Metanotum medially and entire propodeum light 

 yellow; sides of metanotum light yellow. Mesopleura blackish 

 brown. Abdomen entirely blackish. Frontovertex ferrugino-tes- 

 taceous; face more brownish, deepening to fuscous under the eyes. 

 Scape concolorous with the face, remainder of antennae blackish. 

 Hind coxae, trochanters, and femora light yellow, concolorous with 

 propodeum; tibiae suffused with fuscous basally. Middle coxae 

 mostly blackish; trochanters, femora, and tibiae brownish touched 

 in parts with fuscous. Fore legs similar to the middle legs except 

 that the coxae are not so dark. All tarsi brownish. 



Pedicel somewhat more than one-half as long as the first funicle 

 joint, almost one and one-half times as long as wide. First funicle 

 joint plainly the longest, slightly more than twice as long as wide; 

 second and third successively decreasing in length and increasing 

 in width so that the third is only slightly longer than wide. First 

 club joint a trifle shorter and wider than the third funicle joint; 

 succeeding club joints slightly decreasing in size distad; third 

 almost one and one-half times as long as wide (fig. 21). 



Mandibles shown in Figure 174. 



Fore wings rather extensively infuscated beneath the marginal 

 vein with a diagonal pale streak extending from the base of margi- 

 nal vein downward and outward to near the posterior margin oppo- 

 site the end of the marginal vein (fig. 75). Cilia of disk, dense, 

 short; noticeably coarser under marginal vein. Marginal fringe 

 short. Marginal vein plainly longer than submarginal; postmargi- 

 nal shortly produced; stigmal as shown in Figure 112. 



Scutellum wider than long (7:6), not quite so long as the meso- 

 scutum. In tag mounts after shrinkage, the thorax from tegula to 

 tegula is apparently unusually wide, especially in proportion to the 

 abdomen. After shrinkage the abdomen appears narrower than the 

 thorax and not quite as long ; about one and one-fourth times as long 

 as wide. Figure 13 is more or less diagrammatic and does not give
