Phrixocnemis inhabilis n. sp. 



Type: 9 ; St. Louis, Missouri. November 15, 1903. Col- 

 lection of Morgan Hebard. 



Allied to P. bellicosus Scudder from Colorado, but differing 

 chiefly in the somewhat larger size, stouter antennae, shorter 

 posterior femora, and more regularly disposed spurs of the 

 posterior tibiae. 



Size medium, form obese, surface smooth. Head short and broad ; 

 vertex depressed, subvertical ; interspace between the eyes very broad ; 

 eyes roughly diamond-shaped, distinctly projecting ; palpi with the fifth 

 joint very sHghtly longer than the third, curved, excavated below for a 

 slight distance from the tip ; antennae about equal to the body in length. 

 Pronotum slightly compressed, rotundato-arcuate in transverse section ; 

 anterior and posterior margins subtruncate, lateral lobes with the inferior 

 margin truncate. Mesonotum and metanotum with the exposed portions 

 subequal, posterior margins truncate ; lateral lobes slightly deeper than 

 those of the pronotum, inferiorly arcuate. Abdomen little compressed ; 

 supra-anal plate trigonal ; cerci tapering, about half as long as the ovi- 

 positor ; subgenital plate transverse, rotundate ; ovipositor slightly 

 arcuate, robust, regularly decreasing in width, slightly more than half the 

 length of the posterior femora, apex obliquely truncate with the upper 

 point produced into a distinct spiniform process, inner valves with five 

 distinct apical hooics. Anterior femora slightly longer than the pronotum, 

 inferior margins unarmed. Median femora bearing two to three spines 

 on each of the inferior margins, no genicular spine present. Posterior 

 femora about two-thirds the length of the body, moderately expanded, 

 slightly more than three times as long as broad, genicular region not con- 

 stricted, inferior margins moderately serrato-dentate, intervening sulcus 

 broad ; posterior tibiae slightly shorter than the femora, moderately 

 arcuate, four pair of strong spurs present, calcaria stout, those of the 

 external face subequal, the internal face with the two superior ones sub- 

 equal and considerably longer than the inferior one, inferior surface with 

 an apical pair of adpressed spines, and a few inconspicuous scattered 

 spinules ; posterior metatarsi about equal to the fourth tarsal joint, second 

 and third joints subequal. 



General color ferruginous, the abdominal segments suffused with 



chestnut ; eyes blackish.
