168 RHYNCHOPHORA. 
coarsely punctate-striate, and with interrupted lines of white pubescence on the disc. 
The suture is densely pubescent for some distance beyond the scutellum. 
18. Anthonomus canescens, sp. n. (Tab. X. figg. 3, 3a, 3.) 
Oblong-ovate, shining, nigro-piceous, the antenne (the club excepted) and the base of the femora rufo- 
testaceous ; sparsely clothed with long, coarse, white pubescence, which is condensed down the middle 
of the prothorax, on the scutellum, and at the base of the suture, and seriately arranged on each of the 
elytral interstices; the vestiture of the under surface dense at the sides. Head, rostrum, and antenne 
as in A. albolineatus. Prothorax convex, transverse, rounded at the sides, narrowed and constricted in 
front, coarsely, closely punctate. Elytra oblong, convex, wider than the prothorax, sharply margined at 
the base, the humeri swollen; coarsely and deeply punctate-striate, the interstices feebly convex and 
very sparsely punctulate. Femora each with a sharp triangular tooth; tarsal claws with a long tooth. 
Length 4-4}, breadth 14-17 millim. (¢ 2.) 
Hab. Mexico, Acapulco (Hoge). 
One pair. Closely allied to A. albolineatus, but with the long, coarse white 
pubescence extending up each of the elytral interstices to the base, and much less 
condensed on the suture behind the scutellum. 
19. Anthonomus incanus, sp. n. 
Oblong-ovate, shining, black, the antenne (the club excepted) rufo-testaceous; sparsely clothed with fine 
grey or whitish pubescence, which is a little condensed along the middle of the prothorax, on and behind 
the scutellum, and subserially arranged on the elytra, the vestiture of the under surface white, dense 
at the sides. Head sparsely punctate, foveate above the eyes, which are large and rather narrowly 
separated; rostrum (¢) as long as or longer than the prothorax, curved, seriate-punctate, sparsely 
punctured at the tip, (@ ) longer and smoother, the antenne in the ¢ inserted at about one-third, and 
in the 2 at two-fifths, from the apex. Prothorax transverse, convex, rounded at the sides, narrowed 
and constricted in front, coarsely, closely punctate. Elytra a little wider than the prothorax, convex, 
parallel anteriorly, the base sharply margined ; coarsely and deeply punctate-striate, the interstices more 
or less convex and sparsely punctulate. Femora each with an acute triangular tooth; tarsal claws with 
a long tooth. 
Length 23-33, breadth 15-14 millim. (d Q.) 
Hab. Mexico, Mazatlan, Ventanas, Colima city (Hége), Cuernavaca (/7. H. Smith). 
Two males and two females. Very similar to A. canescens, but smaller and less 
elongate, and with finer pubescence; and differing from A. albolineatus in the absence 
of the line of dense white pubescence along the suture at the base. It is possible that 
these three insects may prove to be forms of one very variable species. A. tncanus also 
resembles the North-American A. albopilosus, Dietz, but it has the prothorax convex 
and more coarsely punctured, the elytra a little depressed towards the base, with the 
anterior margin more raised, &c.
