HOMOPTERA 



percurrent; sides of pronotum roughly sculptured with a suggestion of a curved ridge behind the humer- 

 al angles and extended downward to cover more than half of the tegmina; dorsum gradually rounded 

 from top of crest to tip of posterior apex of pronotum which is heavy, tectiform, and just reaches the 

 tips of the tegmina. Tegmina about one-third exposed, the basal and costal areas densely punctate and 

 coriaceous; five apicaland two discoidal cells; median apical cell triangular and petiolate. Legs simple; 

 hind tarsi longest. 



Type brachteata Stal. 



Geographical distribution : Only two species, both from South America, have been describ- 

 ed for this genus but there are unquestionably more species to be described, for we have seen un- 

 described material in many coUections standing under Amastris which undoubtedly belonged to Erosne.

Polyglypta Burmeister, Handb. Ent. II : 142 (i835). 



Characters : Long, slender, narrow-bodied insects with the pronotum stiongly ridged longitu- 

 dinally, a long, slender horn projecting forward, corium with two contiguous longitudinal veins and with 

 five apical cells and with the dorsum rounded and convex. Head roughly triangular with heavy rugas; 

 base sinuate, lowest in the middle ; eyes globular; ocelli small, twice as far from each other as from the 

 eyes and situated well below a line through centers of eyes; inferior margins of gense strongly sinuate; 

 clypeus extending for half its length below inferior margins of genee, its sides continuing the triangular 

 shape of the face made by the margins of the gense. Pronotum low, convex, strongly. longitudinally 

 ridged; anteiior pronotal horn long, strong, porrect, extending forward over the head; metopidium pro- 

 jecting forward, keeled, broader th;in high; median carina strongly percunent; no suprahumerals; hu. 

 meral angles weak, rounded ; sides of pronotum strongly, longitudinally ridged and punctate and extend- 

 ed downward to cover more than half of the tegmina; dorsum nearly straight, highest just behind line 

 of humeral angles, gradually curving to tip of posterior process which is long, slender, convex, acuminate, 

 and reaches beyond the tips of the tegmina. Tegmina not more than one-third exposed, hyaline, with 

 basal and costal areas strongly punctate; two prominent longitudinal veins; five apical cells;median 

 apical cell stylate ; apical limbus narrow. Legs simple, subcylindricai : hind tarsi slightly longer than 

 the others.
