104 STUDIES IN NORTH AMERICAN MEMBRACID/E 



4. Vanduzea laeta Goding. PI. 2, fig. 31. 



The Cornell University collection has a long series of this 

 species that were taken in Arizona. Here the pronotum is 

 carinated much as in Cyrtolobus and the markings are essentially 

 those of that genus but the carina is less elevated. The an- 

 terior oblique vitta however is broader and curved about a seg- 

 ment of a dark semicircle, becoming evanescent anteriorly ; fre- 

 quently it is connected with the median spot where the appear- 

 ance is that of an oblique band angled on either side as de- 

 scribed by Dr. Goding. It is smaller than scgmentata and is 

 more acutely carinated. 



5. Vanduzea bajula Goding. PI. 2, fig. 32. 



This species differs from its congeners in having the pro- 

 notal crest sinuated and in the female somewhat nodulose. Dr. 

 Goding described this species as an EvasJimcadea: the female 

 as bajula and the male as arizoncnsis. That genus however is 

 hardly distinct from Cyrtolobus and differs from Vanduzea in 

 having three longitudinal nervures at the base of the elytra. 

 The female is very pale yellow with a blackish lunule on either 

 side and some darker marks on the metopidium and along the 

 crest posteriorly. The marking on the metopidium forms a 

 ray on either side and before the apex there is sometimes a 

 paler vitta. The male is pale brown irrorated with lighter an- 

 teriorly, and posteriorly shows the characteristic Cyrtolobus 

 marks in an abbreviated curved anterior pale vitta, a transverse 

 vitta before the apex and a pale spot in the dorsal sinus. In 

 the Cornell University collection is a long series from Arizona. 



Genus Polyglypta Burmeister. 



This genus of tropical Membracids is well represented in 

 the fauna of Mexico and Central America. . It may be disting- 

 uished by its slender depressed form and the long porrect an- 

 terior pronotal horn. One species has been reported from our 

 territory. 

 Polyglypta dorsalis Burmeister. 



This is well figured in the Biologia (pi. viii, fig 5.) It has 

 been reported from Savannah by Fairmaire and from Texas 

 by Provancher.
