ARTHROPOD FAUNA OP TKE WEST INDIES. 479 



at least, to look upon the two as distinct. I have seen no speci- 

 mens which .justify Bollinan's views on the variability of the 

 length of the rostrum. 



SiPHONOPHORA. TENUICORNIS, Sp. n. (PI. XXXVII. fig. 4.) 



Colour entirely ochraceous. 



The rostrum long aud slender, about twice as long as the head, 

 lightly curved. Antennce long and slender, only gradually and 

 slightly incrassate. 



Number of segments about 106. 



Length about 20 mm. 



Locality. St. Vincent {H. H. Smith.) 



" Forest, Morne a Garou, 1500 ft. In rotten wood." 



This species differs from S. luteola, G-erv., and S. mexicana, 

 Sauss., the only American species of the genus that are known to 

 me, in the length and slenderness of its antennae. 



Family Poltzonid^. 



Q-enus Siphonotus. 



Stphonottjs pukptjeeus, sp. n. (PI. XXXVII. fig. 5.) 



Colour (in alcohol) a purplish red ; legs pale. 



Body elongate and slender, not entirely concealing the legs. 



Head triangular, gradually narrowed to a pointed rostrum, 

 apparently furnished on each side with two large, black, prominent 

 eyes, the upper of which are covered by, but visible through, the 

 first tergite. Antennce considerably longer than the head and 

 very thick, being almost of a uniform thickness throughout. The 

 segments smooth and polished; the anal segment much narrower 

 than the one that precedes it. Legs tolerably long. 



Number of segments 37-44. 



Length up to about 7 mm. 



Locality. Sfc. Vincent {S. H. Smith). 



"Mountain forest, 2500 ft. Under bark. Colour light 

 purple." 



This species appears to me to differ generically from the 

 Palgearctic Polyzonium germanicum, since it is much more slender 

 and has fewer eyes. There can be little doubt that it is con- 

 generic with the species to which Brandt gave the generic name 

 Siphonotus.
