PTILODACTYLA. 641 



Prothorax short, moderately convex in front, sharply margined at the sides, the latter rounded and 

 rapidly converging from a little before the base to the apex, the hind angles acute ; the base trisinuate, 

 denticulate, and with a short projecting tooth in the centre; the surface thickly granulate-punctate. 

 Scutellum rugulose, deeply notched in the centre in front. Elytra moderately long, sharply margined 

 and a little rounded at the sides, wider than the prothorax, the humeri rounded ; shallowly punctate- 

 striate, the interstices rugulosely punctured. Fifth ventral segment in the male deeply emarginate at 

 the apex and with a short longitudinal groove in front of the emargination. Tarsal claws rectangularly 

 dilated in both sexes. 

 Length 4|-4§, breadth 2 millim. ( <$ $ .) 



Hab. Mexico, Frontera in Tabasco (Hoge). 



Three examples. Very like P. granulicollis, but shorter and less parallel, the fifth 

 ventral segment differently formed in the males, the claws similar in both sexes. 



24. Ptilodactyla gracilis. 



3 . Moderately long, subparallel, flattened above, shining ; somewhat thickly clothed with rather long, very 

 fine, brownish pubescence ; black, the antenna? and legs black or piceous, the tarsi in great part testaceous. 

 Head densely punctured, the eyes large; antennae as long as the body, slender, joints 4-10 each with a 

 slender ramus, the rami becoming longer outwards, the outer four much longer than the joints themselves. 

 Prothorax short, transversely convex in front, acutely margined at the sides and apex, the sides rounded 

 and converging from about the middle forwards and subparallel behind, the hind angles acute ; the base 

 trisinuate, and very feebly denticulate at the sides and in the middle ; the surface closely, somewhat 

 coarsely granulate-punctate, and feebly, transversely depressed before the base. Scutellum rugulose, 

 deeply notched in the centre in front and also sulcate anteriorly. Elytra moderately long, flattened on 

 the disc and also transversely depressed below the base, wider than the prothorax, subparallel in their 

 basal half and a little produced at the apex, sharply margined ; punctate-striate on the disc, the striae 

 not extending to the apex and becoming indistinct at the sides, the interstices flat and somewhat thickly 

 punctured. Legs long and slender. Fifth ventral segment deeply emarginate at the apex. 

 Length 3f~4|, breadth 1|-1 T \ millim. 



Hab. Guatemala, Cerro Zunil, Zapote, Capetillo (Champion). 



Four examples, all males, from the Pacific slope. This small species is not very 

 closely allied to any of the others here described, and chiefly distinguishable by its 

 black colour, close punctuation, brownish pubescence, and long black antennas. 



25. Ptilodactyla antennalis. 



3 . Oblong-elliptic, narrow, flattened above, shining, thickly clothed with rather long pallid pubescence ; 

 rufo-testaceous, the eyes black, the antennae and legs testaceous. Head rugulosely punctured, the eyes 

 large and prominent ; antennas long and slender, the joints 4-10 each with a rather long ramus, 

 joint 3 very much shorter than 4. Prothorax short, convex in front, sharply margined at the sides 

 and apex, the sides rounded and rapidly converging from a little before the apex to the apex, the hind 

 angles acute ; the base trisinuate, feebly denticulate, and with a short projecting tooth in the centre ; the 

 surface thickly granulate-punctate. Scutellum rugulosely punctured, deeply notched in the centre in 

 front. Elytra rather short, sharply margined and a little rounded at the sides, slightly wider than the 

 prothorax ; shallowly or obsoletely punctate-striate to near the apex, the interstices thickly punctate. 

 Fifth ventral segment feebly subtriangularly emarginate at the apex. 

 Length 3|-4, breadth 1^-1-f millim.
