of the posterior femora, stout basally but tapering to a fine point; sub- 

 genital plate divided for half its length. Anterior femora exceeding the 

 pronotum by about one- sixth the length of the latter, armed with a single 

 preapical spine on anterior inferior margin; tibia? somewhat flattened but 

 unarmed above. Median femora about equal to the anterior pair in length, 

 armed inferiorly on the anterior margin with two and on the posterior mar- 

 gin with five spines ; tibite armed above with two pairs of spines. Posterior 

 femora moderately stout, three times as long as broad, armed below on the 

 distal half of the external and on almost the entire length of the internal 

 with closely set, short teeth, intervening sulcus deep; tibiee equal to the 

 femora in length, straight, bearing four pairs of spurs, and between them 

 «upplied a number of blunt spines of the second grade, below armed with 

 two apical pairs of spines and a longitudinally disposed series of four spines ; 

 middle calcaria but slightly longer than the upper pair; metatarsi slightly 

 longer than the fourth tarsal joint, second joint slightly longer than the 

 third. 



Female. — Similar to the male except for the following points: Ovipositor 

 almost two-thirds the length of the posterior femora, stout basally, slender 

 apically, the apex obliquely truncate and produced above into a spiniform 

 process, internal valves with five recurved hooks; cerci short, thick basally, 

 tapering ; subgenital plate transverse, rounded, with no appreciable median 

 emargination. Median femora armed on each inferior margin with three 

 spines. Posterior femora slenderer than in the male, almost three and a 

 half times as long as broad; tibiie armed with but three spines in the in- 

 ferior longitudinal series instead of four. 



General color ochraceous, suffused above and particularly on the margins of 

 segments with Vandyke brown. 



Measurements: Length of body, male 26.5mm., female 24mm.; length of 

 pronotum, male 6.8 mm., female 6.5 mm.; greatest width of pronotum, 

 male 8.6 mm., female 7.5 mm. ; length of posterior femora, male 16.5 mm., 

 female 14 5mm. ; length of ovipositor, 9mm. 



Two additional specimens, a male and a female, from the type locality have 

 also been examined, both smaller than the type individuals. 

 Daihinia brevipes Haldeman. 



Colorado; July, F. H. Snow. One male, one female. 



Clark county, Kan., 1962 ft. ; F. H. Snow. One female. 



The male individual has, with the preapical spine, but one exceptionally 

 large spine on the external margin of the posterior femora. 

 Udeopsylla nigra Scudder. 



Douglas county, Kan. ; June. One male. 

 Udeopsylla robusta Haldeman. 



Clark county, Kan., 1962 ft. ; June, F. H. Snow. One male. 



Colorado ; July, F. H. Snow. One male. 



The University collection also contains a large male individual of this 

 species from Sedgwick county, Kan., collected by E. S. Tucker. 



Udeopsylla serrata, n. sp. 



Type: Male. Southern Arizona; August, 1902, F. H. Snow. Differing from 

 U. robusta and nigra by the smaller spines of the inferior margin of the 

 posterior femora, and the considerably smaller size. From U. vierecki, 

 with which it agrees in the spine armature of the posterior femora, it dif- 

 fers in the smaller size, slenderer posterior tibite, and the slightly more re- 

 curved lateral lobes of the mesonotum and metanotum.
