CERES A BUBALUS, Fab. 
(Plate XXXV. figs. 4, 4a.) 
Cenlrotus bubalus, Fab. Walk. l.c. p. 531. 
Pale brown or ochreous, with fine dark punctures and witli an obscure streak on 
the pronotum; tegmina clear hyaline, with raised ochreous nervures, enclosed 
rhomboidal areas ; suprahumerals short and stout; blackish at the tips. Fairmaire 
notes that Ccntrotus bubalus probably is Ceresa diceros, or it is very near it. My 
figure is from a specimen in Mr. Pippon’s Collection which closely agrees with several 
examples marked Cenlrotus bubalus in the British Museum. 
Size 9x5 mm. 
Habitat .—North America. 
Mr. Ernest Green of Peradeniva, Ceylon, published in the Entom. Month. 
Magazine for August 1900, an interesting paper on the attractive properties of certain 
larval Hemiptera. He further published in June 1901, a memoir on the extensile 
organ of the larva of a Centrotus. He identified this species as Ccntrotus bubalus 
and subsequently he obligingly forwarded me specimens preserved in weak alcohol. 
Mr. Green correctly calls this insect Centrotus, but the specific name can hardly 
be C. bubalus, which Fairmaire and others point out is a true Ceresa, and as far as 
I know is a genus exclusively American. 
Some examples of the genus Ceresa are very like some short-horned Centrotidae, 
and except from the isolation and distances of the Old and New World continents, 
at first sight it would be difficult to separate some mixed species, say Smiliinse and 
Centrotinse. 
It is to be regretted that a less obscure character of the Centrotidae cannot 
be found, than that of the masking of the scutellum by the overhanging pronotum. 
Old and New World species have each their peculiarities, and these may be grasped 
as a whole, yet they almost preclude an exact definition. 
When the subdivision Centrotinae is described, Mr. Green’s species will come 
under notice ; but there I propose the new name of Ccntrotus nectaris in exchange for 
Ccntrotus bubalus , and retain that of Ceresa bubalus. 
CERESA VARIABILIS, Fowler. 
(Plate XXXV. figs. 5, 5a.) 
Fowl. l.c. p. 105. 
Castaneous brown, shining ; pronotum more or less clouded, with the dark fuscous 
surface indented and finely punctured ; suprahumeral horns short; tegmina shining 
and irridescent like mica, with brown neuration ; legs pale fuscous. 
Some specimens differ so much from others, that some entomologists might 
suggest specific characters and count the insects as distinct. Walker describes thirty-
