432 Dr. A. S. Packard, Jr's Revision of the 



hind the large yellow tubercle; two dots on the scutellum, and a yel- 

 low stripe on the nieta-scutelluin. Propodeum very broad short, tumid 

 on the sides; enclosure small, thickly but rather finely punctured, but 

 not striated; sides smooth and polished, with a dense, fine hirsuties, 

 and a deep mesial impression. Tegulse testaceous; wings unusually 

 long, cells elongate, especially the outer subcostal which is nearly 

 twice as long as usual ; the outer margin is unusually oblique. Le<'s 

 reddish throughout, tibiae yellowish above, fore femora yellowish to- 

 wards tips beneath ; basal joint of abdomen unusually broad, resembling 

 that of Monedula; on all the segments is a pair of unusually broad 

 yellow bands, sis in number, those on rings 2 — 3 dilating on the front 

 edge of the sides, which is somewhat sinuate. 



Length .42 inch. 



Louisiana, (Coll. Ent. Soc. Phil.). 



In the very clavate autenua}, very narrow front, its lono- leo-s and 

 wings, broad basal abdominal ring like that in Monedula, and in the 

 two dots on the scutellum, the striped meta-scutellum, the yellow mar- 

 gin of the scutum, and small triangular punctured enclosure, with the 

 short, tumid, smooth, posterior part of the propodeum ; the long legs, 

 with the tarsi concolorous with the rest of the legs, together with the 

 remarkably narrow clypeus, short head, the front sunken below the 

 level of the eyes, — are characters indicating its relationship to the 

 Bembecidas, and easily separating it from any of the preceding 

 species.
