Niteliopsis affinis Roh. 



Niteliopsis affiyiis Rohwer; Trans. Am. Ent. Soc, XXXV, 11.3-4; 



1909. ^ 5 . 



This is a very small, shining black species, described from Colorado. 

 It seems rare in Kansas, where it was taken in Gi'aham, Norton, Ellis, 

 Ness and Rush counties; June- August, 1912. 



Niteliopsis inerme (Cress.).

 Niteliopsis inermis Rohwer; Trans. Am. Ent. Soc, XXXV, 110-11; 



1909. ^ . 



A good series from western Kansas; Grant, Barton, Norton, Phillips, 

 Ellis, Ness and Rush counties; June-August. The insect is rather easily 

 recognized by its pale yellow markings. 



Niteliopsis katisensis n. sp. 



o . Anterior margin of clypeus narrowly lobed mesad; antennae sub- 

 clavate, joint 2 stouter than either .3 or 4; 3 and 4 subequal, the fourth 

 narrow at the base; front not vei-y finely granulate-punctate, the carina 

 to clypeus distinct, a slight impressed line from ocellus forward; vertex 

 granulate-punctate, scutum moderately so, the pleurae inclined to be 

 coarse-punctate; disc of propodeum coarse-rugose, with indications of 

 longitudinal striae at the base; a broad, rough, moderately deep fovea 

 for more than the apical half of the disc, some coarse transverse apical 

 striae, sides finely striate, posterior face granulate-striate, a strong median 

 fovea; legs feebly spinose; second recurrent nervure received in the second 

 submarginal near its tip; transverse-cubital vein arising a little basad 

 of the basal vein, marginal cell narrowly truncate. Segements of the 

 abdomen somewhat constricted basally, basal segments most distincly 

 punctate; pygidial area lacking. Black; mandibles rather dark rufous 

 near the middle; tubercles, a spot posteriorly on each side of the median 

 line of the pronotuni, apex of femora (and also the middle femora very 

 slightly), and the hind tibiae at their base outwardly, yellow; clypeus and 

 lower part of the face, thoracic pleurae and sterna, .<rilvery pilose; ab- 

 domen somewhat pilose. Length, 4.75 mm. (type). 



Norton county, Kansas; August, 1912. 



A second o is entirely black, excepting for the apical portion of the 

 tubercles. This, the cotype, is from Barton county; June 22, 1912. It is 

 allied to plenoculoides and niger; from the first it differs in being smaller, 

 in lacking the carinate pronotum, in having a coarser sculpture on the 

 propodeum, and a somewhat different venation; from niger it may be 

 distinguished by the finer punctation and in not being all black (except 

 for a portion of the mandibles) .
