Oecleus campestris BALL 



Very closely allied to borealis but the vertex is slightly 

 wider and the nervures over the entire elytra are much 

 more distinctly and darkly punctate. 



General color dark fuscous, with all the caririae, the narrow mar- 

 gins of the scutellum, the pleural pieces, and a cloud or vitta near the 

 lateral angles of the scutellum, fulvo-testaceous. 



Head distinctly broader than long, somewhat semicircular in 

 outline. Vertex distinctly wider tflian in borealis, slightly produced 

 beyond the eyes, rather wide at the apex. Frons strongly narrowed 

 at base where the median carina is nearly obsolete. Pronotum short, 

 deeply and angularly emarginate behind, lateral carinae, on the disc, 

 and the margins, pale. Scutellum 5-carinate. Elytra nearly trans- 

 parent, without the smoky apex of borealis; fche nervures pale but 

 distinctly and darkly punctate. Legs pale, lineate or clouded with 

 fuscous. 



Length of body 3.25 mm.; length to tip of elytra 5 mm. 



A single female of this western species beaten by the 

 writer from a pine tree at Columbus, Miss., June 25, 1921, 

 and carefully compared with the type series in the Ball 

 collection. 



THE GENUS MYNDUS STAL 



This genus was erected by Stal in 1862 and is almost 

 entirely limited to North America. Thirteen species have 

 been described from the United States, one of which is 

 known only from the Pacific Coast. A single species, musi- 

 vus, occurs in Europe and differs from its American con- 

 geners in having a black frons and clypeus. 



Closely related to Oecleus. 



Briefly characterized as follows : Vertex long and subrectangular, 

 about three times as long as the pronotum, median carina indefinite 

 or obsolete, produced to a slightly rounded, obtuse apex. Frons nar- 

 rowed above, broadest at clypeus, a median carina with an ocellus 

 placed at its apical end. Eyes large, kidney-shaped, emarginate 

 below. Antennae very short, the second segment subglobose. Prono- 

 tum short, tricarinate, the lateral carinae placed very close to the 

 median one on the disc. Scutellum rather long, tricarinate. Elytra 

 longer than the abdomen, broad, dilated towards the apex, broadly 

 rounded off behind. Female with white flocculent secretion at tip 

 of abdomen. Hind tibiae without spines. 



Logotype of the genus: Myndus musivus Germ. 



Prof. Herbert Osborn found nymphs of Myndus radicis 

 occurring upon the roots of Impatiens, nettles and some
