Elaterites scuJptilis, sp. n. (PI. XVI. fig. 9.) 



Elytron 7 mm. long and 1"8 mm. wide, the base truncate, 

 the apex pointed. Nine delicate strite, very finely punctate, 

 the foiu- inner ones with the punctures subol)soIete, the 

 others with distinct though very dclioate punctures. The 

 outer strise are more closely placed than the four inner ; 

 the fifth stria (from within) is one mm. from inner margin. 

 Punctures on outer striae about 9.")-130/i. apart. Between 

 the inner series of strite the surface is extremely finiily 

 rngnlose, with lines inclined to be transverse or oblique, but 

 irregular, as in the living Cardiophorus fenestratus, Lee.

 ))r()bal)lc total length at least 9 mm. Width 2*4 mm,; dark 

 brown, with eleven rows of round punctures ; the rows close 

 together, and the punctures so placed that often two of one 

 row and two of the next will nuirk the four corners of a 

 square space ; punctures about G in a mm. lengthwise, and

Curculionidae. 



CurcuUuailes inciryinatns, Gii bel. 



Elytron convex, about 6 mm. long and 3 mm, wide ; with 

 six visible (probably one or two oblitcrati'd) longiluilinal 

 rows of verv large deep punctures, squarish .ind somewhat 

 longer than wide. Each Vow contains about 20 punctures, 

 and there are between 4 and 5 punctures in 2 mm. lonni- 

 tudinaliv. Trausversclv, there are 5 rows in 2 mm. Tlie 

 intervals between the punctures are not larger, but often 

 rather smaller, than the punctures themselves.
