between the hind coxe, second segment half the length of the 
first, the suture deep at the sides, apparently straight, but 
almost obliterated, in the middle. The sides of the thorax in 
front are gradually shortened downwards; the angles formed 
by their junction with the pectoral canal can hardly be called 
ocular lobes. 
The type of this genus can be recognized by the long 
rostral canal, which extends into the metasternum. The 
numerous species referred to Acalles are difficult to identify 
by description alone, so I think advantage may be taken of ~ 
any well-marked character to lessen the difficulty. Nos. 1274, 
1290, 1291, and 1292 should, I think, be located in this 
genus. I have not been able to study the sternal structure of 
these four species in a satisfactory manner; but they are so 
much alike in general appearance and in habit that they form 
one natural group. In No. 1292, however, the third tarsal 
joint is more lobate. 
Metacalles aspersus, sp. n. 
Piceous, clothed with pale ferruginous and grey, elongate, 
depressed scales, and erect, slender, fuscous sete ; rostrum 
and antenne red, club pitchy, tarsi fuscous. 
Rostrum finely sculptured, smooth along the middle. 
Antenne inserted behind the middle of the rostrum, shining ; 
club opaque, with dense pubescence. Zhoraw as long as 
broad, its frontal half a little depressed and broadly but not 
deeply constricted ; its surface with large shallow punctures 
and narrow interstices, the sculpture indistinct in front. 
Elytra cordate, widest before the middle, the shoulders much 
rounded ; they are punctate-striate, their clothing is shorter 
and less depressed than that of the thorax; on the third inter- 
stice on each elytron there is a small setose elevation near 
the base and another on the summit of the declivity; on the 
fifth there are two ill-defined elevations. Legs infuscate, with 
long upright sete and also with short, erect, and decumbent 
grey hairs; tarsi narrow, basal joint rather elongate, yet 
shorter than the fourth. 
Underside piceous, a little shining, with a few fine grey 
sete. ‘The two basal segments with some coarse shallow 
punctures, the fifth red, more finely and closely punctured, 
third and fourth very short, with straight deep sutures. 
Var.—Antenne testaceous, tarsi reddish. ‘This is mounted 
on its back, and the description of the underside has been 
recorded above. 
Length (rostr. excl.) 7, breadth quite 3 line.
