between the hind cox^e, 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 sette ; rostrum 

 and antennae red, club pitchy, tarsi fuscous. 



Rostrum finely sculptured, smooth along the middle. 

 Antennce inserted behind the middle of the rostrum, shining ; 

 club opaque, with dense pubescence. Thorax 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 setse and also with short, erect, and decumbent 

 grey hairs 5 tarsi narrow, basal joint rather elongate, yet 

 shorter than the fourth. 



Underside piceous, a little shining, with a few fine grey 

 setae. 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, — Antenna testaceous, tarsi reddish. This is mounted 

 on its back, and the description of the underside has been 

 recorded above.
