XXV .—Descriptions of four new Species of the Genus Ino- 
peplus (Coleoptera, Cucujkke). 13y Charles O. Water- 
house. 
I HAVE not had an opportunity of examining the species upon 
which Laporte established the genus Ino , and am therefore 
somewhat in doubt as to whether the species here described 
really belong to that genus. If the species described by 
M. Fairmaire (Ann. Ent. Fr. 1869, ix. p. 208) as Ino picta, 
Lap., is the same as that described by Laporte, it appears to 
me that all the eastern and American species at present in¬ 
cluded in the genus must be separated, on account of the form 
of the thorax and of their not having the penultimate joint of 
the tarsi bilobed. Laporte, however, does not mention this 
bilobed joint. 
The generic name Ino being preoccupied in Lepidoptera, I 
have adopted Inopeplus , proposed as a substitute for it by 
Mr. F. Smith. In the event of the separation above men¬ 
tioned taking place, the eastern species will fall into Eury- 
platus , Mots. 
The following species are in the British-Museum collec¬ 
tion. 
Inopeplus ceneomicans. 
Elongatus, aeneus, micans; capite coriaceo, sat crebre evidenter 
punctato ; thorace coriaceo, sat crebre subtilius punctato, ante 
basin constricto; elytris subtiliter coriaceis, purpureo-aeneis, 
sutura aenea ; abdomine nitido, subtilissime coriaceo, parce subti- 
lissime punctulato, cupreo et viridi-aeneo micante ; antennis pedi- 
busque piceis, tibiis rufo-piceis. 
Long. 2 lin. 
Head a little broader than long, slightly narrowed before 
and behind the eyes, which are prominent; in the middle 
there is a distinct longitudinal impression. Antennae pitchy, 
the basal joint aeneous, club-shaped, as long as the two fol¬ 
lowing together; 2nd joint short, scarcely longer than its 
width at the apex, the 3rd to 11th gradually and slightly 
increasing in length. Palpi pitchy, the apical joint of the 
maxillary pair elongate fusiform. Thorax scarcely broader 
than long, with a very slight angular projection rather behind 
the middle of the side ; behind this it is gently sinuate and 
obliquely narrowed to the base. Elytra about as long as 
the head and thorax together, rather broader behind than at 
the base, separately obtusely rounded at their apices, coppery 
asneous, green at the suture, rather brighter coppery at the 
apex. Abdomen with four segments exposed above, shining,
