114 STUDIES IN NORTH AMERICAN MEMBRACID./E 



Leioscyta pallidipennis Stal. 



In the Cornell University collection is one female from 

 Arizona bearing the label "Bolbonota difformis Uhler", evi- 

 dently a MS name, that I believe to be the female of this 

 species. The type specimens were from Mexico. The present 

 specimen has the pronotum more angled before, the posterior 

 process longer and the head more rounded at apex than shown 

 in the Biologia figure but these differences are probably sexual. 

 If I am right in this determination Stal's cornatula is sufficiently 

 distinct. 



Genus Multareis Goding. 



This genus may be distinguished from all its North 

 American allies in having the anterior pronotal process trans- 

 versely flattened and bilobed at apex. In one specimen the 

 median carina is raised as it passes over the apex at the point 

 of this reentrant angle. Dr. Goding described this genus in 

 the Ccntrotida but it almost certainly belongs to the Membra- 

 cida. Unfortunately my material is too scant to allow of my 

 dissecting a specimen to determine if it have a scutellum. The 

 tibiae are flattened but hardly foliaceous as in our other genera. 



Multareis cornutus Goding. PI. 2, fig. 37. 



Dr. Goding described this species in 1895 f rom a pair taken 

 in Panamint Valley, California. Prof. Wickham has very 

 kindly given me a similar pair taken by him in St. George, 

 Utah, in July. 



Genus Tylopelta Fowler. 



Tylopelta gibbera Stal. PI. 2, fig. 34. 



The Cornell University collection contains a long series of 

 this insect from Arizona which was determined by Dr. Uhler 

 as Bolbonota carinata Uhler, a MS name that was never pub- 

 lished by him Dr. Goding in his catalogue published in 1894 

 describes a species as Tropidoscyta amcricana which I believe 

 is but a pale form of Stal's species and in this I am confirmed 

 by his statement that "this species may be found in collections 

 under the MS name carinata." The descriptions by both Stal
