anterior horn short and blunt, projecting forward and upward with a single 

 strong ridge in the middle of each side which continues downward and back- 

 ward over the humeral angles and reaches the lateral margin of the pronotum ; 

 anterior and posterior portions of horn very foliaceous ; a black line extend- 

 ing from tip of horn to humeral angles ; another black line following the 

 ridge throughout its course and becoming wider at lateral margin ; a small 

 black spot on the margin midway between this ridge and the apex of posterior 

 process; tip of posterior process black; all the rest of the pronotum bright 

 scarlet. Posterior process gradually arcuate, tip depressed and sharp, reach- 

 ing just about to the tip of the abdomen but not reaching the ap'.ces of tegmina- 



Tegmina hyaline with a black transverse band across center and with base 

 black, opaque, pubescent and punctate. 



Under surface of body black ; legs entirely red. 



Length from front of head to tips of tegmina 4 mm. ; from apex of 

 pronotal horn to tips of tegmina 5.1 mm.; width between humeral angles 

 2 mm. 



Type : male. 



Locality: Xapo River, Peru. June, 1920 (Parish). 



Small brilliant scaflet and black species; horn short and projecting 

 forward; tegmina hyaline banded with brown; legs red; under stirface 

 of body black. 



Tropidoscyta immaculata new species. (PI. I, fig. 3.) 



Head longer than wide, brown, very finely punctate, closely pubescent 

 with silvery hairs; base sinuate; eyes large, conspicuous, yellow; ocelli large, 

 conspicuous, yellow, farther from each other than from the eyes and situated 

 above a line drawn through centers of eyes ; gense rounded ; clypeus extend- 

 ing below margins of genae, rounded and pubescent at tip. 



Pronotum not foliaceous, uniformly light brown, finely punctate, closely 

 pubescent with fine silvery hairs ; anterior produced forward in a blunt point ; 

 a long well-defined ridge on each side extending from tip of point downwards 

 and backwards over the humeral angles and ending at the lateral margin of 

 the pronotum ; two or three faint ridges extending from this ridge down- 

 wards over the metopidium ; dorsal margin of prothorax sinuate ; median 

 carina percurrent from head to tip of posterior process and very sharp ; pos- 

 terior process gradually acuminate, reaching just to the internal angles of the 

 tegmina and about as far as the apex of the abdomen, 



Tegmina opaque flat yellow ; basal costal cell coriaceous and punctate, 

 apex slightly wrinkled ; five apical and three discoidal cells. 



Legs and under surface of body uniformly light brown and densely 

 pubescent. 



Length from front of head to tips of tegmina 3.7 mm. ; from anterior tip 

 of pronotum to tips of tegmina 4.5 mm. ; width between humeral angles
