eludes very heterogeneous material as must be evident to even a superficial 

 observer. No one can deny the necessity of approaching Entimus and its 

 allies to Cyphus, forming a distinct tribe, however, from the latter, and at 

 the same time Leptops must be similarly dealt with, and should probably 

 be placed with the Entimides. As far as I have studied the majority of 

 the genera of the group Leptopsides vrais, should remain in the present 

 tribe. 



As Leptops belongs to my second division, I have been compelled to 

 change the name of the tribe, and have adopted that of our most prominent 

 genus. 



As interpreted in the present paper, this tribe has the following charac- 

 teristics : 



Rostrum moderately or very robust, quadrangular or sub-cylindrical. 

 Mandibles robust, never prominent or laminiform at tip, scar round, very 

 distinct and sometimes prominent. Mentum large or at least moderate, 

 concealing in great part the other oral organs, sub-mentum rarely feebly 

 pedunculate. Scrobes lateral, rarely {Phyxelis) visible from above, di- 

 rected either toward the middle of the eyes or inferiorly. Antennis mode- 

 rate, scape always attaining at least the eye, funicle T-jointed, the last 

 usually free, rarely {Cimhocera and Ophryastes) contiguous to the mass. 

 Thorax always with distinct ocular lobes which are frequently fimbriate. 

 Metasternnm usually very short, side pieces usually narrow, suture nearly 

 always visible. Mesosternal side pieces unequally divided, episternum 

 and elytral margin contiguous. Intercoxal process at least moderately, 

 sometimes very broad {RhirjopHi!<). Abdomen variable, second segment 

 longer than the two following united (except in Ophryastes), and with the 

 first suture arcuate (except in Ophryastes and some Strangaliodes). Tarsi 

 variable, usually pubescent beneath, sometimes spinous ; third joint usually 

 deeply bilobed and broader, rarely simply emarginate and not wider than 

 the second, (certain Ophryastes, and in Cimbocera and Bhigopsis). Claws 

 always free. Body always apterous. 



The tribe contains moderately homogeneous material but with evident 

 tendencies in some of the genera to closely approximate those of neighbor- 

 ing tribes, especially is this the case in those genera with the feebler ocular 

 lobes. Thus Phyxelis approaches Trachyphloeus and Phymatinus to 

 Otiorhynchus. There is very little tendency to approch Division II, 

 Phymatinus alone having the mesosternal side pieces nearly equally divided 

 but the metasternal parapleurse are not at all like those of that division. 



The genera of the tribe form the following groups: 



Rostrum robust, quadrangular, more or less distinctly trisulcate above. 

 Scrobes rapidly inferior, well defined. Eyes always narrow and acute 



below, partially concealed by the ocular lobes. 

 Abdomen with second segment rarely as long 

 as the two following together, first suture 

 straight. Intercoxal process moderately 



wide. 



Ophryastes.
