with long setose hairs, the hind tibia also with a few rigid bristles 



apically. Form of body broadly oval with shorter legs 



Perigenes, p. 727 



8. First segment of antenna exceeding apex of tylus by one-half its 



length. Anterior margin of pronotum depressed, punctate. Basal 

 disk of scutellum depressed before a premedian, transverse or 

 crescentic ridge, posteriorly carinate. Fore femora armed with 

 several teeth. In brachypterous forms membrane may be almost 

 or entirely wanting, the clavus flat, not deflected to corium and 

 anterior lobe of pronotum swollen and more than twice the length 



of posterior one. Species not at all or only slightly shining 



Ptochiomera, p. 728 

 First segment of antenna short, scarcely exceeding the tylus. 

 Anterior margin of pronotum not depressed. Basal disk of 

 scutellum depressed followed by a longitudinal carina. Incras- 

 sate fore femora armed with two or three preapical teeth one of 

 which is frequently enlarged. In brachypterous forms the mem- 

 brane is only a little shortened, the clavus always deflected to 

 the corium. Species very shining Kolenetrus, p. 72S 



9. Anterior lobe of pronotum impunctate, demarked from posterior 



lobe by a transverse impressed line ; provided with a distinct ring- 

 like collar. Basal segment of antenna with a few setose bristles. 

 Ocelli absent. Fore tibial tooth of male at middle or posterior to 

 middle. Hind tibia provided inwardly and outwardly with rigid 

 bristles. Basal segment of hind tarsus three times as long as 



second and third together. Large species Cnemodus, p. 729 



Anterior lobe of pronotum sparsely punctate, two lobes separated 

 by an obtuse sinus, not indicated by an impressed line; anterior 

 margin depressed, punctate. Basal segment of antenna without 

 setose bristles. Ocelli present. Fore tibial tooth of male anterior 

 to middle. Hind tibia with a few setose bristles inwardly. Basal 

 segment of posterior tarsus about twice the length of second and 

 third together. Smaller species Pseudocnemodus, p. 729

A very distinctive species by reason of its long, slender, cylin- 

 drical neck. The head is shining, the pronotum dull black; the 

 hemelytra brown with pale margin. By reason of the slender 

 body the legs seem rather long, the fore femora being longer than 

 the intermediate ones ; the former as well as the posterior femora 

 are apically piceous. The apex of the second segment of the ros- 

 trum does not reach the base of the elongated head. The hind 

 tarsus is very long, at least three times as long as second and third 

 together. Size 8-9 mm. 



This is a widely distributed species sheltering under boards, etc., 

 on the ground and is in part at least predaceous.
