ba.sc of tibi;e: micklle femora of males provided with four or five 

 strong teeth : anterior lobe of pronotum punctate. Head and pro- 

 notum provided with a few long set^e. Posterior margin of pronotum 

 not so sinuated above base of scutellum. 



Pseudocnemodus bruneri, new species. 



Smaller and more shining than Cnemodus iiiavortius Say. Dark casta- 

 neous, with post-ocular margins of head more swollen and with fore femora 

 more incrassate. Head dull dark castaneous, closely punctured, not pubescent 

 but provided with a few long setae. Tylus lighter colored. Head shaped much 

 as in mavortitis but the post-ocular and ante-ocular portions to base of antennae 

 sube(|ual. Swollen post-ocular part distinctly wider across than the collar of the 

 pronotum. Apex of head almost reaching the middle of basal joint of antennae, 

 which is about two thirds as long as second : third segment apically thickened 

 and apical three fourths fuscous, about three fourths the length of second ; 

 fourth segment a trifle longer than third and colored reddish-brown. First 

 joint of rostrum nearly reaching base of head. Head unicolorous beneath, sub- 

 shining, with a few fine scattered punctures. Collar of pronotum short and 

 not sharply demarked, there closely punctured. Anterior lobe shining, with 

 scattered punctures on the disc, a little longer than wide and about two and 

 one half times longer than the posterior lobe, which is dull paler castaneous, 

 more closely punctate and wider than the anterior lobe. Humeral angles cal- 

 losed, smooth, pale. Seen from the side, the posterior part of this lobe is 

 elevated to the height of the anterior lobe. Posterior margin of pronotum not 

 so concave as in C. mavortitis. Scutellum dark castaneous or piceous, not 

 closely punctate, pale at acute apex and with apical half distinctly keeled. 

 Corium wider than the abdomen, dark castaneous, verging to piceous in dark 

 specimens, not closely punctate except without exterior vein, not very shining. 

 Wide costal margin strongly reflexed, pale yellow, impunctate. Membrane 

 incomplete, infuscated, reaching base of sixth abdominal segment, provided 

 with about four sinuous veins. Genital segment of male seen dorsally more 

 concave than in C. mavortius. Pleural pieces rather closely and coarsely punc- 

 tured, shining. Exterior apical angle of metasternum and coxal plates pale 

 stramineous. Venter shining castaneous, with very fine hairs on the disc. 

 Connexivinn beneath paler. Legs shorter than in C. mavortius, pale stramineous, 

 with shining anterior femora relatively shorter and more swollen, and pro- 

 vided with two rows of five or six larger equidistant spines, with a few 

 minute ones nearer apex. Fore tibial spine of male placed nearer apex than 

 base of tibia, the basal part nearly straight. Middle femora of male armed 

 with three or four stout, acute teeth. Precoxal tooth acute, horizontal. Hind 

 femora unarmed. Apical half of fore femora and tibiae, apex of second and 

 third femora more faintly fuscous. Length of (^, 5.5 mm. ; J, 6 mm.
