rounded behind, lower than the scutellum, rather concave, me- 

 dianly longitudinally ridged, closely, finely punctate, yellowish; 

 postscutellum long, narrow, surpassing the femoralia which cover 

 the sides of the body and several abdominal segments. The 

 thorax, with the exception of the postlumbium, is finely pubescent. 

 Elytra short, narrow, apically thickened and rumpled into many 

 ndges, thickly pubescent. Wings large, surpassing abdomen, 

 consisting merely of the primary veins, costa, subcosta, radius, 

 and media from the costal stalk and cubitus and anus from the 

 anal stalk; radius arises from sub-costa ; none of the veins are 

 branched. The legs can be illustrated better than described. All 

 have four tarsal joints, and these joints each inserted far before 

 the apex of the preceding and with the apex sucker-like. The 

 coxa of the first two pair seems to be single-jointed, long, while 

 the posterior pair apparently has a rather short coxa and a long 

 trochanter. The femora and tibiae are on all pairs longitudinally 

 obliquely furrowed. 



The abdomen is short and is mainly characterized by the pe- 

 culiar genital apparatus. From the anal opening there projects 

 a tube, which is immediately dilated, then turned and narrowed 

 into a very acute curved process. 



Female. 1 — A mere sac with chitinized head and neck. Sur- 

 face closely reticulately marked. Color fiavus, with neck and gen- 

 eralized head-structures darker to very dark brown. 



Owing to certain limits on the present article a brief statement 

 of existent structures will be made here and complete drawings 

 will accompany this article, but the detailed discussion of the 

 structures must be published later in a distinct article. Speci- 

 mens at hand show clearly the existence of several species. Cer- 

 tain characters lead us to believe that pulvinipes belongs to an 

 undescribed genus. The head is rhomboidal, narrowed in front 

 and constricted behind the eyes. The eyes are distinct and promi- 

 nent, not faceted. The nerve cord leading to the eyes is very 

 easily found. The mouth-parts are retracted but distinct. 

 Breathing pores are distinct on each side of the body, on each 

 segment.
