THE CANADIAN ENTOMOLOGIST. 381 



Cabinet of Natural History." While my time was all too limited, 

 especially with the Harris collection, I made a careful examination of 

 certain of the species, and in the present paper and in the one published 

 in the October number of this journal I give some of the more interesting 

 results of my studies. 



At the end of 'this paper I add a list of the type species in the several 

 genera of the Hemiptera thus far established by me. Many of these types 

 have already been placed, either inferentially or directly, but all are 

 repeated here for convenience of reference. 



Anotia Bonnetii, Kirby. 

 In the Harris collection preserved in the museum of the Boston 

 Society of Natural History, is an example of this insect which agrees 

 entirely with my own determination of the species. It very closely 

 resembles Amalopota Fitchi, but is paler, the elytra are more hyaline and 

 have a different venation (see Can. Ent., XXV, p. 280, Nov., 1893), the 

 head is narrower before the eyes and more produced superiorly, and the 

 antennas are narrower and more terete. Judging from the form of the 

 antennse I would say that the specimen standing under this name in the 

 Fitch collection is probably Amalopota Fitchi. I still think it best to 

 retain the genus Amalopota, although it is scarcely more distinct from 

 Anotia than is Hynnis from Otiocerus. 



Lamenia vulgaris, Fitch. 



An examination of the type preserved in the Fitch collection in the 

 State Museum at Albany shows this to be the large form found on oaks 

 throughout the Northern States. In this the male plates are very large, 

 with their inner edges slightly parted at base, then feebly sinuated to their 

 rounded apex, which is armed with a long inwardiy curved tooth, as in 

 the allied species. In my description of L. Californica (Can. Ent., 

 XXIII, p. 169, Aug., 1891), I applied the name vulgaris to another and 

 a smaller species, which, perhaps, is not distinct from obscura, Ball. In 

 most northern specimens of this smaller species there is a reentrant angle 

 on the inner edge of the male plates, but its depth is subject to variation, 

 and a sufficient series might show a gradation into obscura, in which this 

 angle is wanting. 



Ceresa bubalus, Fabr. 



Under this name in the Fitch collection is an example of Ceresa 

 borealis, Fairm., as the species is determined by me in my studies in North 

 American Membracidae. The varieties "a" and "b" of Fitch are my 

 Ceresa albescens.
