144 HOMOPTERA 



one-third the body length in the female the hoin compressed at apex, cut off obhquely and occa- 

 sionally expanded. There are three lateral carinas. The pronotum covers most of the elytra, is 

 acutely tectifoim with four or five lateral carina;, the inner one with branches to the highest part 

 of the crest. The face is slightly longer than in Publilia, the venation of the elytra similar. »

118. genus bilimekia fowler 



Bilimelcia Fowler, B. C. .\. II : 127(1895). 



Characters : Insects which greatly resemble the species oi Polyglypta, with long, slender bodies 

 and single poriect pronotal horns, but with the posterior end of the pronotum bluntly rounded, with the 

 head trilobed,the tegmina almost entirely covered and with only three apical cells in the tegmina. Head 

 subquadrate, twice as broad as high, strongly trilobed; base nearly straight; eyes very much flattened; 

 ocelli inconspicuous, farther from each other than the eyes and situated on a line drawn through centers 

 of eyes ; inferior marginsof genae extending downward in large rounded lobes, to form, with the clypeus, 

 a trilobed ventral outline of the face. Pronotum long, slender, cylindrical ; dorsnm convex; metopid- 

 ium merging gradually into the inferior surface of the pronotal horn; humeral angles very weak, prac- 

 tically obsolete ; pronotal horn long, cylindrical, projecting forward over the head, strongly ridged on 

 all sides, apex blunt; sides of pronotum strongly, longitudinally multicarinate, extending downwards 

 to almost completely cover the tegmina; posterior process very blunt and rounded, just reaching the 

 tips of the tegmina Tegmina almost entirely covered by the sides of thepronotum; hyaline; three 

 apical cells and one discoidal cell; apical limbus narrow. Hind wings with three apical cells. Legs 

 much inclined to be foliaceous, particularly the front and middle tibiae which are distinctly flattened. 

 Hind tarsi a little shorter than the others. 



Type styliformis Fowler. 



Geographical distributlon : The two described species are both from Mexico and both are 

 apparently quite abundant since they are generally to be found in collections from that country.

119. GENUS ENTYLIA Germar 



Entylia Germar, Rev. Silb. I : 178 (i835). 



Characters : A very distinct genus recognized at once by the laterally flattened dorsum with 

 a deep broad notch in the center which results in prominent high anterior and posterior lobes. There 

 are no other processes or protuberances. The pronotum is strongly ridged and the tegmina are largely 

 covered by the overhanging sides of the pronotum. Head roughly triangular with inferior margin 

 rounded; base sinuate, lowest in middle and with the superior lateral margins angulate above the eyes; 

 eyes ovate with inner surfaces straight; ocelli prominent, elevated, nearer to each other than to the eyes 

 and situated considerably below a line drawn through centers of eyes; inferior margins of genae sinuate ;
