greater than that between the anterior ocellus and the posterior ocelli, but not so 

 much greater as the distance between them and the nearest eye margin. 



Third joint of the antennae is a little shorter, if anything, than the scape, 

 which is approximately as long as the fourth joint. The second joint of the an- 

 tenufe a little less than one-half the length of the fourth joint. The fifth and 

 succeeding joints of the antennte subeqtial. 



The antennal joints, except the second, very distinctly demarcated. The an- 

 terior of the clypeus entire, as is the jtosterior margin of the pronotum. In addi- 

 tion to the appressed pubescence, there is a rather loose collection of rather erect 

 and silvery hairs, especially around the head and pronotum. 



The maxillary palpi are six jointed, with the second and fifth joints of nearly 

 the same length, that is approximately of the same length of the second joint of 

 the antennfe. The third, fourth and fifth joints subequal, each distinctly longer 

 than the preceding. The first joint approximately half the length of the second 

 joint. The labial palpi four jointed, with the joints subequal. The longestspur 

 of the posterior legs approximately as long as the metatarsus. 



Wings. — Hyaline, a rather broad fuscous margin at the tips. The nervures 

 very dark brown, stigma pale brown. Transverse median nervure interstitial 

 with the basal nervure. The third abscissa of the radius a little shorter than the 

 second abscissa and a little longer than the first abscissa. Spurs, mandibles at 

 base, band on the posterior aspect of the posterior tibite and the tip of the dorsum 

 of the abdomen yellowish to whitish. 



Type. — University of Kansas. 



Type locality. — Morton Co., Kansas, 3200 ft. 



One male collected in June, 1902, by F. H. Snow. 



Aporus ferrugineipes u. sp. 



The ferruginous femora and tibise of the posterior legs help to 

 distinguish this form from its allies. 



9 . — 6 mm. — Black, covered with a grayish bloom, excepting a band across the 

 pronotum just anterior to the posterior margin, the disk of the scutellum, a band 

 across the first dorso-abdominal segment, all, excepting the apical band on the 

 2nd, 3rd and 4th dorso-abdominal segments without bloom, as are the apical two 

 abdominal segments, the apical band on segments 2, 3 and 4 with a grayish 

 bloom. 



Anterior margin of tiie clypeus entire, scape approximately as long as the third 

 joint of the antennae. The second joint of the antennae half the length of the 

 third. The fourth joint of the antennae a little longer than the third joint. The 

 succeeding joints subequal. The j)ronotum with the posterior margin entire. The 

 metathorax laterally in the middle prolonged into distinct short acute processes. 

 The tegument is apparently impunctate. 



Color. — Apical lialf of the mandibles is largely reddish, as are the posterior 

 femora and tibiae. 



Type. — University of Kansas. 



Type locality. — Clark Co., Kansas, 1962 ft. 



One female collected in May (F. H. Snow).
