THE CANADIAN ENTOMOLOGIST. 249 



Proarna invaria (Walker). Mr. DislaiU has copied the mistake into his 

 Catalogue of Cicadidse. 



The second volume of the Homopterous part ends very abruptly at 

 p. 316, in the middle of a sentence ; this was published in August, 1903 ! 



In the Heteroptera (Vol. II.) Mr. Champion has confused under one 

 generic name, Liitevopsis, two distinct genera. 



Luievopsis, type lo?igimanus, Champ., has a few large spines on the 

 fore femora, and the hind femora extend much farther than the abdomen 

 posteriorly, and are not pilose ; the tegmina are not picturate. 



Panamia, gen. nov., type ornata (Champ.), is somewhat allied to 

 Ploiariodes^ White, but has no scutellar spines ; it has no large spines on 

 the fore femora, the hind femora do not extend farther posteriorly than the 

 abdomen, and are lightly pilose ; the tegmina are picturate. 



The head and pronotum are also very different in the two genera. 



Since the publication of Bulletin IV of the Div. Ent. H. S. P. A.. I 

 have received Melichar's fine Monograph of the Issinse, and have been 

 able to confirm the two Issines noted by me from Arizona. 



(i) Briichomorpha f?iormo, Kirk., is allied to B. pallidipes, Stal, but 

 is concolorous except part of the legs (duly described). 



(2) Picumna ovatipemiis (Walker) may be confirmed. 



1. P/intk(Erus mexicanus, Spinola, 1850, Mem. Soc. Ital. Modena, 

 XXV (?ep. p. 115). This genus is treated by Stal, in discussing the 

 Ethiopian forms, as a homonym of Ptyelus, Lep. and Serv. I cannot 

 identify P. mexicamis with any of the Cercopidae enumerated by Fowler. 



2. The use of Tetigofiia in Hemiptera has been objected to by Jacobi 

 (in his current works) as being preoccupied by Tettigojiia in Orthoptera. 

 I cannot agree, especially as Geoffroy does not refer to Linneus's genus ; 

 even then, however, Jacobi's new name, Tettigoniella, would fall before 

 Cicadella, Latreille, i<Si7 (Cuv. R^gne An., Ill, '06), of which the 

 Tettigonia of Olivier and Germar is the typical subgenus, as stated by 

 Latreille himself. 



3. Microcentrus, Stal, 1869, = Phaulocefitrus, Fowler, 1896. Stal 

 gives caryce (Fitch) as the type of his Membracid genus. Fowler rarely 

 cites types for his genera, but as caryce is the first mentioned, it may be 

 taken as the type. 



4. In the B. C. A. Hom., II, Fowler refers to the Achilius bicitictits, 

 Spinola, redescribes and figures what he supposes to refer to it. 



I do not believe that Spinola's species really refers to Colgorvia 

 {~\\Rudia) ; Stal was uncertain. Yo-wltx's bi ductus can scarcely be the
