of our fauna. Rtifa is much broader and less convex, and 

 has black legs and antennae. The punctuation, especially of 

 the elytra, is distinctly dual in size. 



H. foliacea Lee, and H. pimctipeimis Lee. 



A comparison of the types of these two species shows 

 them to be practically identical, the structure of the last ven- 

 tral in the males being virtually the same notwithstanding 

 Horn's statement of difference. The name punctipennis was 

 first given by LeConte in MSS., and reference is made to it 

 in the description of foliacea ; the latter, however, was pub- 

 lished first and must prevail. 



HEMIGLYPTUS Horn. 

 This genus is here mentioned in order to call attention to 

 a somewhat serious error in Horn's Monograph of the Halti- 

 cini. The genus was erected for the Crepidodera basalts of 

 Crotch because of the presence of a terminal spur on all the 

 tibiae, and it is said by Horn to differ in this respect not only 

 from the other species of Crepidodera, but from all other 

 genera of the Halticini. In another place he says that all 

 the tibiae are thus armed in Blepharida and Hemiglyptus only. 

 A careful examination shows that the terminal spur is present 

 on all the tibiae of all species of Crepidodera in my collec- 

 tion, and furthermore, not only Blepharida, but several other 

 genera are similarly equipped. The spurs of the front and 

 middle tibiae are it is true very small and difficult to detect 

 in so small an insect as a Crepidodera, but they may be seen 

 at a glance in the larger species cf Haltica and Syslena. 

 Although the genus Hemiglyptus cannot stand on any peculi- 

 arity of tibial armature, it may properly be retained because 

 of a number of divergencies from typical Crepidodera. notably 

 the confused elytral punctuation. 



CREPIDODERA Chev. 

 C pallida n. sp. 



Elongate oval, entirely testaceous, shining. Antennae half as long 

 as the body, rather slender, joints 3-4 subequal, outer joints very 

 gradually slightly longer, the tenth more than twice as long as wide. 

 Frontal tubercles and carina moderate. Prothorax one-fourth wider
