FAM. MEMBRACIDiE 177 



to the extent of occasionally showing margins which suggest that they have been chevved by phyto- 

 phagous enemies. The pronotum is greatly elevated, flattened and foliaceous and the tibia; are more 

 or less dilated. Head subquadrate, about as broad as high, foliaceous, trilobed; base strongly arcuate; 

 eyes much fiattened laterally; ocelli conspicuous, twice as far from each other as from the eyes and 

 situated near the basal margin of the head, high above a line dravvn through centers of eyes; inferior 

 margins of genae extended into flattened rounded lobes; clypeus very narrow, forming the weak median 

 lobe of the head and not extending below the inferior margins of the genae. Pronotum elevated into 

 a high, compressed, leaf-like irregular crest, usually brownish or greenish in color; no definite meto 

 pidium, the anterior margin of the pronotum rising directly above the head with little lateral expansion ; 

 median carina strongly percurrent; humeral angles weak, triangular, blunt; sides of pronotum punctate 

 and irregulaily ridged with reticulate carinas; posterior process high, tectifoim, reaching just about to 

 the internal angles of the tegmina; scutellum very httle exposed on each side. Tegmina broad, trans- 

 lucent; basal area coriaceous and punctate; apex obtusely triangulat, truncate or rounded; veins prom- 

 inent; fiveapical and two discoidal cells; no apical limbus. Tibiae of all legs dilated; hind tarsi longest.

160. GENUS GLISCHROCENTRUS FOWLER 



Glischrocentrus Fowler, B. C. A. II : 161 (i8g6). 



Characters : We have never seen the species cucullatus on which this genus was founded, and 

 which is the only species in the genus, and can judge the genus only from the original description and 

 figures. Fowler's description, while very short and not as complete as might be desired, seems to leave 

 no doubt as to the validity of the genus and his figures are excellent. Goding (1927) considered this 

 genus a synonym of Blanchard's Melizoderes but this cannot be correct since MeUzoderes has no posterior 

 process while Fowler not only figures this process but discusses it in his description of the type species. 

 Fowler considered Glischrocentrus as closely related to both Microctntrus and Ischiioctnirus Stal, and dis- 

 tinguishes it from the latter by the fact that in Glischrocentrus the posterior process touches the tegmina 

 while in Ischnocentrus it is high above the tegmina. His description and figures. however, show more 

 important diiferences, particularly in the wing venation and in the shape and character of the clavus.
