Very elongate, cylindrical. Piceous or brown, shining, glabrous; an- 

 tennae and legs reddish-brown. Head and beak finely punctured. Thorax 

 subcylindrical, more than one-half longer than wide, slightly narrowed in 

 front, disc finely, not densely punctured, without impressions, its sides 

 rounded near the base. Elytra not wider than thorax, stria? rather wide, 

 shallow, much deeper on the posterior declivity, their punctures rather 

 coarse, serrate, close-set; intervals narrow, convex. Under surface distinct- 

 ly but finely punctured; flanks of thorax feebly concave in front. Length

Dunedin, Fla., scarce beneath drift on the beach of bay ; Jan. 

 21 March 21. A strictly maritime and semitropical species, 

 first found by Hubbard and Schwarz at Haulover, Fla., in March, 

 when it was abundant on the sea shore under boards. A colony 

 of 30 or 40 were found by Schwarz under a log at Padre Island, 

 Texas. Eleven taken under drift and 50 more on the under side 

 of a wide, flat oak plank, June 29, at same place by Wickham. 

 Occurs only on open coast, not lagoons, under driftwood which 

 is partly soft, so the larva? can cling to it. (Totonsend, 1903.) 

 Occurs also in West Indies and Hawaiian Islands. 



VI. STENANCYLUS Casey, 1892. (Gr., "narrow" -j- "curve.") 



Elongate, narrowly oval species having the head rather elon- 

 gate, conical; beak short, broad, parallel, not constricted at base; 

 basal joint of funicle as long as the next two, second to seventh 

 short, subequal, feebly increasing in width; eyes very convex, 

 prominent, coarsely granulated; front coxa? widely separated. 



835 (11,222). STENANCYLUS COLOMBO: Casey, 1892, 693. 



Elongate, narrowly oval, convex. Pale rufo-piceous throughout, glab- 

 rous, polished. Head and beak continuous, finely, not densely punctate; 

 beak two-fifths as long as thorax, straight. Thorax slightly longer than 

 wide, broadly, feebly constricted near apex, sides feebly curved, disc finely 

 unevenly punctured without trace of median line. Elytra wider and 

 more than twice as long as thorax, sides parallel and straight to apical 

 third, then convergent and sinuate to the narrowly obtuse apex; stria? 

 coarsely feebly impressed, coarsely punctate; intervals narrow, finely uni- 

 seriately punctate. Beneath coarsely punctate. Length 2.2 2.4 mm.
