There is only one species from the Island of Morty 

 representing this (otherwise with one other exception) 

 purely Australian group, and some other groups nearly 

 related, most of which I have hitherto treated as Steno- 

 dcrince. The principal diagnostic character of the sub- 

 family is the small round eye. The Malayan representa- 

 tive belongs to SylUtus, which forms an exception to all 

 its allies, inasmuch as the eyes are coarsely granulate ; 

 the species is quite new, and bears a striking resemblance 

 to the Chilian Syllittcs -pseudocupes.

Caput inter oculos elevatum, antice rostro quadrato 

 elongatum. Oculi integri, grosse granulati. An- 

 tennce corpori sequales vel fere Eequales, setaceae; 

 scajyo elongate, obconico ; articulis 3-11 scapo bre- 

 vioribus, inter se gradatim longioribus. Palpi 

 maxillares filiformes. Prothorax elongatus, antice

 Elytra linearia, elongata. Pedes breviusculi, sub-

The species described below differs from the normal 

 Sylh'ti in having each elytron drawn out at its apex into 



* M. Lacordaire substitutes Pterostenus for Stenoderus, Serv., a similar 

 name imder the form of Stenodera having been previously used by Esch- 

 scboltz.
