MinieMa regiilaris Fox. 



Pseii, regtilaris Fox, Trans. Am. Ent. Soc , xxv, 6, 9 > 1898. 



"A.ntenn?e (flagella missing)." Antennse reaching to the middle 

 of the thorax, flagellum thickened more than in M. niger. First joint 

 of the tlagellum about one-third longer than the second. Two 

 9 North Mountain, Sullivan County, Pa. (C. W. Johnson.) 



iVIiinesa striatii!« n. sp. 



Dorsulum longitudinally striate, enclosure of metathorax smooth, petiole slen- 

 der and narrow. J . Length 8 mm. 



Head shining, front with fine somewhat separated punctures, closest near base 

 of antennse, vertex with very fine transverse strise. Space between posterior 

 ocelli seemingly less than space between ocelli and nearest eye margin. Front 

 with a well-defined median carina extending from middle of space between in- 

 sertion of the antennae, to anterior ocellus. Face and olypens with dense silvery 

 pubescence, as in Cylindricus, on the cheeks less dense, silvery, the rest of the head 

 with sparse very short hairs. Antennse slender at base, gradually thickened to 

 the apex, first joint of the flagellum almost as long as the second and third 

 united. Dorsulum with close, fine, longitudinal strife. Mesopleurse minutely 

 striate, sericeus. Scutellum glossy, sparsely punctured, postscutellum with a 

 tuft of white pubescence laterally. Enclosure of metathorax with a somewhat 

 diamond shaped, shining area, the upper boundaries of which are formed by 

 well-marked ridges, followed on each side by at least two other ridges, the spaces 

 between also smooth, the rest of the metathorax dull, reticulated, posterior face 

 with sparse, slender hairs, a tuft of pubescence at base laterally. Wings hyaline, 

 nervures brownish, first and second transverse cubitus almost uniting on the 

 margiiml nervure, second cubital cell receiving the first recurrent nervure a little 

 less than one-third its length from the first transverse cubitus, the second recur- 

 rent nervure almost interstitial with the second transverse cubitus. Femora and 

 tibia} sericeus, posterior tibiae with short stiflF hairs behind. Tarsi with yellowish 

 pubescence. Petiole distinctly trisulcate, longer than the posterior femora, slen- 

 der, of almost equal width throughout. Abdomen smooth, polished, with excep- 

 tion of first segment thinly sericeus. Pygidial area narrower apically than in 

 cylindricus, with strong punctures laterally, impunctate medially, not polished 

 and with long sparse hairs. 



Black. Antennse seal-brown. Tibial spurs whitish, tarsi changing from whit- 

 ish at base to brownish testaceous at apex. 



Related to regularis and cylindricus, to the former by its smooth 

 nietathoracic enclosure, to the latter by its slender, narrow petiole. 

 Readily distinguished by the striate dorsulum. 



Type in collection H. L. Viereck. Type locality, Westville, N. 

 J., August 30, 1899 (H. L. Viereck). A specimen from Avalon, 

 N. J., June 9 (C. W. Johnson) is referred with doubt to this species. 



Since the above was written a specimen of this species has been 

 found in collection Am. Ent. Soc, labelled Fla. $ .
