nearly straight ; base regularly arcuate ; eyes very large, prominent, brown ; 

 ocelli large, conspicuous, amber-colored, translucent, much farther from each 

 other than from the eyes and situated about on a line drawn through centers 

 of eyes; margins of genae projecting at first straight downwards and then turn- 

 ing inwards at a sharp angle to meet the clypeus ; clypeus twice as long as 

 wide, extending only a short distance below inferior margins of gense, tip 

 rounded and strongly pilose. 



Pronotum concolorous light ferruginous, roughly sculptured, coarsely 

 punctate, irregularly pilose with short, scattered bristle-like hairs ; produced 

 upward in two dorsal horns, the first long, sinuate and foliaceous, the second 

 short, erect and nodose ; anterior horn arising from just back of humeral 

 angles, at first erect and turriculate, then extending upward and backward as 

 a broad, compressed, foliaceous, sub-oval plate, then suddenly narrowed to 

 form a short process compressed at right angles to the plate and extending 

 upward and only slightly backward ; posterior horn erect, subturriculate, con- 

 sisting of three rather distinct globular nodes, the basal node broad and some- 

 what flattened, the middle node globose and smaller, the upper node very 

 small and touching the inferior margin of the foliaceous plate of the anterior 

 horn ; posterior process short, heavy, flattened, angular, obliquely truncate at 

 tip which reaches to a point about halfway between the internal angles and 

 apices of tegmina. 



Tegmina long, narrow, ferruginous, basal half opaque, terminal half sub- 

 hyaline ; veins prominent. 



Under surface of body ferruginous-brown ; legs ferruginous ; all three 

 pairs of tibije broadly foliaceous, the middle pair the broadest, all tibije show- 

 ing large, irregular sunken punctures. 



Length from front of head to tips of tegmina 8 mm.; length of anterior 

 horn from top of head g mm. ; width between humeral angles 2.3 mm. 



Type: female. Male agrees except in size which is smaller. 



Locality: Obidos, Brazil. Aug. 23, 1919 (Parish). 



Large, very light ferruginous, concolorous, loughly and coarsely 

 punctate, pilose; anterior pronotal horn at first erect and turriculate, 

 then extending upward and backward as a broad compressed plate, 

 then upward as a narrow process bifid at the tip; posterior horn con- 

 sisting of three globular nodes, one above the other, decreasing in size 

 from below upwards, the top node touching the foliaceous plate of the 

 anterior horn; posterior process short, flattened, angular, obliquely 

 truncate, reaching beyond the internal angles of the tegmina but not 

 extending to their tips; tegmina uniformly ferruginous, veins promi- 

 nent.
