and the sides. Autecoxal ridges very distinct, postocnlar lobes feeble. Thigbs 

 feebly clavate, tibife moderate, subparallel, outer apical angle distinct, tarsi stout, 

 first and second joints not elongate, third distinctly bilobed, fourth projecting 

 about the length of the preceding joint; claws very small, connate two-thirds 

 their length. Length 3.0 mm. ; 0.12 inch. 



Hah. — Texas. 



A male specimen in Dr. Horn's collection. Might be confounded 

 with dark colored specimens of scufpticollis, but is larger, more robust, 

 the beak stouter, more strongly curved, the elytra distinctly, though 

 feebly rounded on the sides, and the fourth tarsal joint more slender 

 and projecting about the length of the third. From ciuereus, which 

 it resembles in size and coloration, it is distinguished by its more 

 rounded sides, stouter form, relatively larger thorax and shorter 

 elytra. A specimen in Mr. Ulke's collection entirely deprived of 

 scales differs in nowise, except that the prothorax is deeply constricted 

 behind the apical margin. 



P. congestiis Casey. — Elongate-oval, rufopiceous, abdomen and pectus 

 pitchy black, and with the exception of the thoracic side pieces, thinly clothed 

 with elongate-oval or piliform yellow scales, condensed on the elytra in trans- 

 verse, wavy lines. Beak rather robust, scarcely as long as head and prothorax 

 in the male, a little longer than these in the female, nearly straight, opaque, 

 rather coarsely punctured in the male, more shining and remotely punctured in 

 its distal half in the female, indistinctly subcarinate, feebly striate each side; 

 basal tufts obsolete, incision not deep ; scrobes feebly oblique. Antennae inserted 

 one-third from the apex ( '^ ), or a little before the middle ( 9 J, not very slender, 

 first joint of funicle a little lo!iger than the second, the latter fully one-half 

 longer than the third ; clava elongate-oval, smaller than usual, basal joint thinly 

 pubescent, subglabrous. Head subopaque, punctured with a few scattered pili- 

 form scales. Prothorax strongly convex, wider than long, not much wider at 

 the base than at the iipex, very strongly rounded on the sides, broadly and dis- 

 tinctly constricted at the apex ; coarsely and densely punctured, each puncture 

 bearing a strongly recurved, hair-like scale, a narrow median and a less distinct 

 lateral line of condensed scales. Scutel very small, almost invisible. Elytra 

 almost regularly oval, two-fifths wider at the base than the prothorax at its base, 

 humeri prominent, rounded, sides regularly rounded to the apex; striae well 

 marked, distinctly and distantly punctured: interstitial sette distinct, humeri- 

 basal line on the third interspace and subtransverse wavy bauds yellow ; brown 

 scales smaller. Antecoxal ridges and prosternal sulcus sharply defined. Legs 

 slender, especially tibise, latter feebly biemarginate and setulose along inner 

 margin, rather strongly armed at the apex ; tarsi and claws as in the preceditig, 

 latter connate .1 little beyond the middle. Length 2.75 mm. ; 0.11 inch. Plate 

 vii, fig. 11.
