in that species and the frontal costa but little produced between the 

 antennae. Eyes large and prominent, fully twice the length of the 

 anterior edge of the cheeks below them, separated above by a space 

 a little narrower than the diameter of the antenna? (9) or by one 

 almosl linear (cf). Occiput heavily carinated longitudinally; the 

 vertex as in fusifortnis. Antenna' robust, about two-thirds (9) or 

 four-fifths (cf ) as long as the head and pronotuni combined. Pro- 

 notum with a glabrous area on upper portion of lateral lobes bordered 

 above by a subcarina, which would take the place of lateral carinas 

 were these actually present. Tegmina more broadly expanded apically 

 than in fusif or mis, reaching hind margin of first abdominal segment, 

 their dorsal edge pallid and irregularly rugose rather than veined, 

 bowed both upwards and inwards apically; the disk shining black and 

 strongly and irregularly punctulate. Basal abdominal segment plainly 

 longitudinally ridged on dorsum between the tegmina and the medio- 

 dorsal carina, the latter prominent and continuous with that of the 

 occiput and thorax. Hind femora rather short and robust, a little 

 surpassing the apex of the abdomen in the female, fully one-third of 

 their length in the male. Outer margin of hind tibia? eight-spined. 

 Prosternal spine strongly transverse and bituberculate at apex. 



General color-pattern as in the preceding species, but inclining to 

 brown instead of testaceous. Hind femora plainly bifasciate trans- 

 versely on upper edge, and obliquely on outer face, upper basal third 

 with a conspicuous grayish brown patch. Anterior and middle legs 

 pallid, more or less mottled and fasciate with fuscous; hind tibia? as 

 in fusiformis. 



Length of body, cf , io mm., 9 , 13 mm.; of pronotum, cf, 2.5 mm., 

 9, 3.25 mm.; of tegmina, cf, 1. 85 mm., 9, 2 mm.; of hind femora, 

 cf, 6.5 mm.. 9 , 7.65 mm.
