Mesochorus noctivagus, n. sp. 



Superficially like agilis, from which it differs in size, sculpture, and color. 



Female. — Length, 4.13 mm. Head shining; face somewhat dullish; cheeks 

 closely, distinctly punctured, the punctures thereon regular, face with the orbital 

 margins punctured nearly like the cheeks, middle of the face with a rather cor- 

 date elevation, the apex between antennal insertion, the base adjoining the 

 clypeus, the elevated portion punctured nearly like the cheeks, between the 

 orbital margin and middle elevated portion of face the punctures are almost ad- 

 joining and smaller than on the cheeks; clypeus polished, very sparsely punc- 

 tured; antenna} over thirty-five jointed (tip broken off), possibly with one or two 

 joints more, scape and pedicellum together distinctly shorter than the first joint 

 of the flagellum. Dorsulum shining, somewhat dullish, parapsidal grooves 

 represented on anterior half of dorsulum by very faint longitudinal impressions, 

 dorsulum rather indistinctly sculptured, distinct punctures in the parapsidal 

 region and on the greater portion of posterior two- thirds; scutellum almost pol- 

 ished, apparently impunctate; metathorax shining, distinctly areolated, the 

 areolie bounded by distinct carina\ areola and basal area confluent, the basal 

 area if completed would apparently be quadrate or nearly, areola if perfect would 

 be hexagonal resembling a diamond with the acute angles cut off, lateral carina 

 of areola angled in the middle or nearly, areola about twice as long as greatest 

 width, smooth, almost polished: petiolarea broader than long, nearly circular, 

 the anterior and lateral margins describing part of a circle, all the areas, except 

 the areola, somewhat roughened; propleura shining, minutely sculptured; 

 mesopleura polished, anterior margin punctured, the punctures not very deep, a 

 broad impression on the inferior portion of the anterior margin, a broad impres- 

 sion ou the middle of the posterior margin and another impression on the anterior 

 portion of the superior margin; metapleura with closely arranged shallow punc- 

 t ires; wings iridescent, very faintly brownish, almost clear, stigma dark brown, 

 the proximal and distal corners with a small pale spot, nervures blackish tes- 

 taceous, first abcissa of the radius as long as the first and second transverse 

 cubiti together, the first transverse cubitus shorter than the second, the first 

 abcissa of the cubitus beyond the first transverse cubitus shorter than the same, 

 the second abcissa almost the same length of the first transverse cubitus, second 

 abcissa of discoidal nervure nearly one fourth the length of the recurrent nervure, 

 transverse median nervure interstitial, areolet sessile, almost quadrate. First 

 abdominal segment subsessile, polished irregularly, rather longitudinally pitted 

 and with a shallow median longitudinal sulcus; succeeding segments polished, 

 sparsely, minutely punctured. Thinly pubescent, the pubescence short and 

 whitish, most abundant on the metathorax. Black; posterior orbital margin 

 brown, anterior orbital margin cream color margined with brown ; malar space, 

 clypeus, mandibles, except tips which are brown, tegulte and base of wings cream 

 color or whitish; antennte very dark brown ; propleura? brownish along the mar- 

 gins; legs mostly testaceous, posterior coxjs and femora somewhat ferruginous, 

 apical tarsal joints fuscous, posterior tibise brownish white, fuscous at tip, meta- 

 tarsus of posterior legs whitish.

Female. Douglas county, Kansas, 900 feet. 



This species was described at length in Entomological News, vol. XIV, pp.
