PTILODACTYLA 645 



Eleven examples. Smaller and less elongate than P. rugulosa, the antenna? with 

 the apical two joints flavo-testaceous, the elytra more distinctly striate, the upper 

 surface more opaque. 



32. Ptilodactyla punctatissima. 



Moderately elongate, flattened above, subopaque ; thickly clothed with fine greyish pubescence, that on the 

 disc of the elytra usually fuscous (leaving the suture and sides paler) ; brownish-black, fuscous, or ruf o- 

 fuscous, the suture and sides of the elytra and the entire head and prothorax sometimes ferruginous, the 

 antennas black, with the two basal joints obscure testaceous and the apical one flavo-testaceous, the legs 

 testaceous, the tibias sometimes infuscate or piceous ; the entire upper surface densely, rugulosely punctate, 

 the under surface very finely rugulose. Head broad, the eyes large and prominent in the male, smaller 

 in the female ; antenna? elongate, slender, the joints 4-10 each with a moderately long ramus in the male 

 and serrate in the female. Prothorax transverse, feebly convex in front, sharply margined at the sides 

 and apex and explanate at the sides behind, the latter rapidly converging from a little before the base to 

 the apex and rounded and slightly converging behind, the hind angles sharp ; the base bisinuate, finely 

 denticulate. Scutellum with a shallow notch in the centre in front and indications of a smooth impressed 

 median line. Elytra moderately long, very little wider than the widest part of the prothorax, subparallel 

 in their basal half, flattened on the disc towards the base, sharply margined at the sides, the apices some- 

 what produced ; obsoletely punctate-striate, the interstices feebly convex, and with a row of ^ moderately 

 coarse punctures within the margin. Fifth ventral segment deeply emarginate at the apex in the male. 

 Tarsal claws rectangularly dilated in both sexes. 



Length 6-7, breadth 2^-24 millim. ( 6 $ .) 



Eab. Mexico, Chinautla, Santecomapan (Salle), Teapa in Tabasco (H. H. Smith) ; 

 Guatemala, Teleman in Vera Paz (Champion). 



Twelve species, eight of which are from Teapa. Smaller, less elongate, and more 

 convex than P. rugulosa, the elytra more distinctly striate, the thorax less flattened in 

 front. Less opaque and distinctly more convex than P. varicornis, the antennae with 

 the apical joint only (and in the male the tip of the last ramus also) flavo-testaceous. 

 The densely rugulose surface and the form of the claws in the male distinguish the 

 present species from P. meocicana and its allies. 



33. Ptilodactyla integra. 



$ . Oblong-elliptic, rather narrow, a little flattened above, shining, thickly clothed with pallid pubescence ; 

 testaceous, with the elytra suffused with piceous— leaving a humeral patch, the suture and sides, and 

 the apex indeterminately, of the ground-colour— and the under surface similarly coloured, or entirely 

 testaceous, the antennas and legs testaceous. Head rugulosely punctured, the eyes moderately 

 large ; antennas long and slender, feebly serrate. Prothorax short, feebly convex in front, the sides 

 rounded and converging from a little before the base to the apex, the hind angles acute ; the base 

 trisinuate, smooth ; the surface thickly, finely punctate. Scutellum transversely cordate, flat, unemargi- 

 nate in front, closely punctured. Elytra moderately long, wider than the prothorax, acutely margined 

 at the sides, and a little produced at the apex, the humeri rounded ; very distinctly and rather coarsely 

 punctate-striate to near the apex, the interstices slightly raised and rugulosely punctured. 



Length 3|-3f, breadth l^-lf millim. 



Hab. Mexico, Toxpam (Salle) ; Guatemala, Senahu in Vera Paz (Champion). 



Two examples, differing in size and colour, both from the Atlantic slope. Closely 

 allied to P. breviscutim, from the Pacific slope of Guatemala ; but differing from it in
