Sipylus nodipennis Funkh. Plate II, fig. 15. 



Sipylus nodipennis Funkh., Journ. Ent. & Zool. (1914), 6, 72, fig. 5. 



Sipylus nodipennis is easily recognized by the nodules on the 

 veins of the tegmina and the thick yellow pubescence over the 

 whole surface of the body. 



The body is subtriangular ; the pronotum slightly wider be- 

 tween the humeral angles than the distance from the anterior 

 convexity to the extremity of the posterior process. The teg- 

 mina are broad, rounded at apex, subhyaline and punctate at 

 base, and characterized by the presence of the tubercles on the 

 veins. The posterior trochanters are strongly armed with teeth. 



Length, female, 3.5 to 4 mm. ; male, 3 mm. ; width at humeral 

 angles, female, 3.5 mm.; male, 2.75 mm.

Genus CENTROTOSCELUS Funkhouser 



The genus Centrotoscelus was erected ^- for the reception of 

 its one species. This genus is peculiar in having no supra- 

 humeral horns and yet having strong teeth on the posterior 

 trochanters. It is entirely distinct from Sipylus, though falling 

 near it in an artificial key. The genus seems naturally closely 

 related to Tricentrus, from which it may be distinguished by the 

 absence of the suprahumeral horns. 



The body is long and comparatively slender ; scutellum distinct ; 

 posterior process short, impinging on scutellum and tegmina; 

 hind wings with three apical areas.

 and 4. 



Ferruginous brown ; pronotum finely and densely punctate and 

 sparsely pilose. Posterior process long, narrow, gradually acum- 

 inate, slightly depressed at tip, extending somewhat beyond in- 

 ternal angles of tegmina; median ridge distinct at apex, but 

 becoming obsolete at metopidium. Tegmina subhyaline, brown 

 and punctate at base, a very narrow brown transverse stripe 

 behind middle and a faint brown cloud at apex. Legs ferrugi- 

 nous; tarsi yellowish; claws black. Segments of abdomen mar- 

 gined with white above. 



Length, female, 5 mm. ; male, 4.33 mm. ; width, female, 2.5 mm. ; 

 male, 2.2 mm.
