330 Miscellaneous. 
coxee antic basi contiguee; mesosternum depressum, leviter ex- 
cavatum; sutura prima abdominis distincta; femora dentata ; 
unguiculi bifidi. 
A very distinct genus, well differentiated from all the forms 
of Centrinus by the dilated sides of the prothorax, and bifid 
claws. ‘The anterior coxe diverge so as to form a continua- 
tion of the pectoral canal. 
Enops interruptus. 
E. breviusculus, rufo-brunneus, sat dense griseo-pubescens ; antennis 
concoloribus ; funiculo articulis duobus basalibus elongatis ; pro- 
thorace fere impunctato ; elytris interrupte carinatis, interstitiis 
biseriatim punctatis. Long. 3 lin. 
Hab. Parana. 
Rather short, yellowish brown, thinly covered with a 
greyish pubescence; rostrum nearly as long as the elytra, 
moderately curved, the basal half with somewhat indefinite 
raised lines, the apex dilated ; scrobes lateral, beginning rather 
beyond the middle; funicle elongate, the first two joints as 
long as the rest together, club oblong ovate ; prothorax slightly 
transverse, the base with a raised line, the dilated part form- 
ing a spinous angle anteriorly ; scutellum smooth, round ; 
elytra triangular, convex, nearly twice as broad as the pro- 
thorax at the base, the shoulders obliquely truncate, each 
elytron with three interrupted raised lines, the outermost 
abbreviated, a fourth marking the abruptly vertical side, 
interspaces with two rows of large punctures ; body beneath 
pitchy, covered with a greyish pubescence; legs somewhat 
slender ; femora subclavate, armed with a small tooth.

On the Proper Generic Name of the Tunny and Albwore. 
By Tueropore Git, 
In 1817, in the first edition of the ‘Régne Animal,’ Cuvier pro- 
posed two subgenera of Scomber, which he employed, however, in a 
generic sense: one, Thynnus, was based upon the common tunny 
(with which were associated other and smaller species), having 
moderate pectoral fins; and the other, Orcynus, was based upon the 
Alalonga of the Mediterranean and characterized by the long pec- 
toral fins. Subsequently by many ichthyologists these two genera 
were combined into one under the name of Z’hynnus. In 1861 the
