Two Neotropical species of the genus Stonmiulus have 

 been described : the first, named hioculatus by G-ervais, was 

 from Colombia ; the second is the species mentioned above 

 from Porto E.ico. The latter I have not seen ; but it appears to 

 differ from the Colombian form in possessing two eyes on each 

 side o£ the head. Species to which an * is prefixed have not been 

 seen by the writer.

Body linear, hairy. The antennae projecting as far as the

 front, and as long as the two following segments. 



Number of segments 71-72.

 1880, p. 144 



Somewhat depressed, brown ; head, rostrum, antennae, and 

 legs flavous. Nostrum longer than the head, the antennas 

 scarcely longer than the rostrum, clavate ; first segment not twice 

 as wide as the head, deeply einarginate in front, not longer along 

 the dorsal middle line than the second segment ; the segments 

 dorsally tolerably thickly covered with short setiform hairs. 



Length 7-8 mm. 



Locality. Cuba. 



Appears to differ from S. portoricensis of Brandt iii its much 

 smaller size, wider head, and much shorter rostrum. 



This species was looked upon by Bollman (Proc. IT. S. Nat. 

 Mus. 1888, p. 335), who also had it from Cuba, as synonymous 

 with S. portoricensis of Brandt. 1 prefer, liowever, at present
