Tegmina hyaline, base coriaceous and punctate, apex slightly clouded ; 

 veins very strong and brown and very strongly punctate with brown dots ; 

 apical cell with basal veins at right angles to length of tegmen. 



Thorax and undersuiface of body uniformly green; abdomen green; legs 

 green ; tarsi luteus. 



Length, 4.8 mm. ; width, 2.4 mm. 



Type : female. Locality : Cali, Colombia. Collector : Parish (May 24, 1914). 



This species bears a strong superficial resemblance to Vanduzea 

 (Hypamastris) segmcntata Fowler and may be but a variety of that 

 species. It is quite distinct, however, from the specimens of segmen- 

 tate/, which I have from Arizona and Texas and which seem to be 

 without question Fowler's species. Fowler credits segmcntata with 

 a wide range and considerable variation. 



Lycoderes triangulata new species. 



Large, reddish-brown, coarsely punctate, not pubescent ; pronotal horn 

 porrect, subcylindrical at base, forked at extremity, the prongs of the fork 

 narrow, flattened and parallel ; posterior process slender, straight, very slightly 

 elevated above the scutellum ; tegmina reddish-brown, opaque, coriaceous and 

 punctate except a large triangular area at costal margin near apex which is 

 entirely hyaline and very conspicuous, suggesting the specific name. 



Head foliaceous, black, finely and closely punctate, finely pubescent, con- 

 vex ; base of head regularly arcuate ; eyes large, prominent, gray ; ocelli promi- 

 nent, shining, orange-colored, much farther from each other than from the 

 eyes and situated well above a line drawn through centers of eyes ; margins of 

 gense sinuate, extended downward to meet apical end of clypeus ; clypeus longer 

 than wide, flat, black, pubescent, punctate, continuing the outline of the head 

 as formed by the inferior margins of genae. 



Pronotum reddish-brown, darker in front, very sparingly or not at all 

 pubescent ; single pronotal horn porrect, extending forward and upward, the 

 base thick and turriculate, the middle portion subcylindrical, the apex forked, 

 the forked portion being nearly as long as the distance from the humeral 

 angles to the base of the fork, the prongs of the fork continuing the general 

 direction of the horn, nearly parallel, not spreading, as seen from the front 

 they are slightly separated at the bases, nearly touching throughout mid- 

 dle half and again slightly separated at the tips, tips a little swollen with 

 points directed outward ; humeral angles prominent, triangular, acute ; pos- 

 terior process long, narrow, straight, cylindrical at base, laterally flattened and 

 sharply carinate for apical two thirds, arising from above the base of the pro- 

 notal horn and extending backward and downward to meet the tegmina against 

 which it is closely pressed, the tip of the process not quite reaching the inter- 

 nal angles of the tegmina ; scutellum plainly exposed, subtriangular, the open 

 space between the scutellum and the posterior process being small, not much 

 longer than the scutellum and not half as high as long.
