Body nearly as in the preceding but rather larger and more elongate, 

 shining, piceous, the elytra rather paler; under surface pale piceo- 

 rufous, the legs pale; head barely visibly narrower than the prothorax, 

 the eyes very prominent; mandibles longer than in the preceding, the 

 frontal foveae larger and deeper, the oblique posterior part deeper and 

 with longitudinal plicae, the fine groove just above and along the 

 eyes more evident; antennae longer and more slender, extending well 

 behind the thoracic base, fuscous, the two basal joints pale; prothorax 

 as in mexicanus but with the sides posteriorly more oblique and less 

 rounded and the flat basal bead more abruptly narrowed from the 

 foveae to the sides; elytra shorter, less than one-half longer than wide, 

 about a fourth wider than the prothorax, the striae rather less im- 

 pressed, the sinus rather more evident, the discal puncture similar; 

 hind tarsi nearly similar. Length (9) 6.5 mm.; width 2.0 mm.

That Mr. Bates should have assigned mexicanus to Cratocara 

 (Polpochila), shows that he could not have given much attention 

 to generic characters in the group and probably had not confirmed 

 the supposed identity of Cratocara with the minute Chilean Pol- 

 pochila. The synonymy of piceus given above is due to that 

 author. The figure of the mouth parts of Pogonodaptus given by 

 Horn (Tr. Am. Ent. Soc., 1881, PL IX) is inaccurate in several 

 particulars and he evidently failed to observe the obtuse tooth on the 

 inner margin of the inner maxillary lobe; the last joint of the labial 

 palpi is relatively too short and the third joint of the maxillary palpi 

 is too long, in the drawing.
