g44 SEBB1C0BNIA. 



Two examples. A very small species, resembling P. montana in colour ; but differing 

 from that insect in its much smaller size and less elongate shape, slender testaceous 

 antenna?, duller surface, shorter, paler, pruinose pubescence, &c. The pubescence is 

 sufficiently close to almost hide the dark ground-colour. 



30. Ptilodactyla rugulosa. (Tab. XXVIL fig. 18, <j .) 



Elongate, flattened above, subopaque, thickly clothed with short, fine, silky, yellowish -cinereous pubescence ; 

 rufo-fuscous, the shoulders of the elytra and the front and sides of the prothorax usually reddish, the under 

 surface obscure ferruginous or ferrugineo-testaceous, the antennas black, with the two basal joints obscure 

 testaceous and the apical one flavo-testaceous, the legs testaceous or obscure testaceous ; 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 ; antennas very elongate, slender, the joints 4-10 each with 

 a moderately long ramus (the rami increasing in length outwards) in the male and serrate in the female. 

 Prothorax transverse, flattened on the disc 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 insinuate and very feebly denticulate. 

 Scutellum moderately large, feebly notched in the centre in front, and sometimes with indications of a 

 smooth median line. Elytra elongate, distinctly wider than the prothorax, parallel in their basal half, 

 narrowly margined at the sides, the apices slightly produced, the humeri rounded; with indications of 

 obsolete striae, and with a row of rather coarse punctures within the margin. Fifth ventral segment 

 somewhat deeply emarginate at the apex in the male. Legs elongate. Tarsal claws rectangularly dilated 

 in both sexes. 



Length 7-7|, breadth 2|-3 millim. ( c? $ .) 



Hdb. Mexico, Jalapa(iZo^). 



Sixteen examples. Easily distinguished by its dull, rugulose surface, and elongate, 

 parallel shape. The anterior portion of the disc of the thorax is flattened, the sides 

 being moderately declivous in front and explanate behind. 



31. Ptilodactyla varicornis. 



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

 of the elytra sometimes fuscous (leaving the suture and sides paler) ; brownish-black, fuscous, or brown, 

 the lateral margins, base, and apex of the prothorax and the suture of the elytra often reddish, the 

 antennas black, with the two basal joints reddish and the tenth and eleventh flavo-testaceous, the legs 

 testaceous, the tibia? sometimes darker ; 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 ; 

 antennas moderately long, slender, the joints 4-10 each with a ramus (the outer ones slightly longer than 

 the joints themselves) in the male and serrate in the female. Prothorax transverse, flattened on the disc 

 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 trisinuate and very feebly 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, narrowly margined at the sides, 

 the apices slightly produced, the humeri rounded ; obsoletely punctate-striate, the interstices feebly raised, 

 and with a row of moderately coarse punctures within the margin. Fifth ventral segment emarginate at 

 the apex in the male. 



Length 5-6, breadth 2|-2^ millim. ( 6 ? .)
