4. S. consors. New sp. 



Dull pale clay brown, inscribed with white and fuscous, form 

 of S. immistus, but with less acute vertex. Head more rounded 

 than in the preceding species, the vertex less depressed, having 

 a yellow sinuous line adjoining the anterior margin bordered 

 before by a slender line, and behind by a black line which is 

 enlarged at the corner of the eye; next the apex is a dusky 

 spot carrying a yellow dot, behind which a yellow double line 

 runs back to the base and then bends outward in a hook ; front 

 pale brownish, darker above, where it is crossed by three or four 

 yellowish lines. Eyes pale brownish, margined behind with 

 white. Prouotum pale grayish brown, transversely wrinkled, 

 with an obsolete pale middle line which is widened at the pos- 

 terior extremity ; in each anterior angle is a larg-e vellowish 

 spot, carrying a dark brown dot, the anterior margin orange with 

 two yellow dots on the middle. Scutellum orange yellow, finely 

 wrinkled, having two yellow remote dots at base, two gemmate 

 ones near the apex, and the lateral margin interruptedly yellow. 

 Beneath and legs testaceous. Apex of last tarsal joint, nails, 

 dots at base of spines on posterior tibiae, tip of the same tibiae, 

 and two broad tarsal bands black. Wino'-covers tinned with 

 pale fulvous and with whitish round spots distributed length- 

 wise on the corium, veins brown, the basal and apical cross- 

 vein of the postnodal cell, that of the tip of adjoining apical 

 cell, a streak at the marginal end of the sectors on the clavus, 

 and tip of clavus dark brown ; apical end of membrane broadly 

 bordered with smoke brown, a few pale brownish clouds occupy 

 the disks of the areoles on the middle. Wings hyaline, with 

 brown veins. Segments of the tergum light brown, with the 

 sutural margins, especially below, bright yellow. 



Length to tip of wing-covers 5^5f millims ; to end of venter 

 4f millims. Width of pronotum IJ millims. 



A novel little species, of which but a few specimens have thus 

 far occurred to me in Maryland. It lives on the Spice bush, 

 lAnderus benzoin, in late summer and autumn. A specimen 

 of the female was sent to me from Waco, Texas, by jNIr. 

 Belfrage.
