624 Coleopterological J^otices^ VII. 



In the male of P. zimmermanni Lee, the body is very de- 

 cidedly narrower, as well as smaller, than in any of those which 

 precede, and is pale in color throughout including the abdomen ; 

 the vestiture is sparse but rather long, and is appressed as usual, 

 the hairs stout but scarcely squamiform. The antennae are quite 

 slender, but the eleventh joint becomes twice as wide as the 

 second ; the ninth and tenth joints are elongate, subequal and de- 

 cidedly longer than any of the preceding. The prothorax is 

 barely as wide as the head, somewhat transverse and rather more 

 than ^ as wide as the elytra. In my previous table of this genus 

 (Col. Not. Y, p. 501), the antennal characters should refer to the 

 female and not to the male ; in the latter sex the last joint is 

 barely as long as the preceding three combined as usual. The 

 specimens in my cabinet are from Louisiana. 



P. Cinderella. — Rather slender and moderately convex, polished and 

 impunctate throughout; body, legs and antennae pale rufo-testaceoas in color, 

 the abdomen barely distinguishably less clear; pubescence rather abundant, 

 appressed as usual, only moderate in length but subsquamiform and distinct. 

 Head and prothorax relatively rather large, equal in width, the former slightly 

 wider than long, the eyes only moderately large but convex and prominent, 

 separated by a little more than three times their own width ; fovese small, 

 equal, forming a small equilateral triangle; antennal tubercles moderate in 

 width, the longitudinal sulcus subobsolete. Antennse slender; joints three to 

 seven elongate, the remainder missing in the type. Prothorax nearly ^ wider 

 than long, only slightly more than J^ as wide as the elytra, parallel, narrowed 

 slightly near the apex, the latter very broad and transversely truncate; median 

 fovea large, extending through basal % of the length. Elytra conspicuously 

 short, fully }4. wider than long, the sides rather strongly divergent and feebly 

 arcuate from the moderate and obtuse humeral swelling; surface moderately 

 convex, the striae normal, the discal rather feeble, becoming obsolete at some 

 distance from the apex. Abdomen as wide as the elytra and very nearly as 

 long, the sides parallel and rounded. Legs slender, the hind tibiae slightly 

 swollen near the tip but not distinctly bent. Length 1.28 mm.; width 0.52 

 mm. 



Texas (Brownsville). Mr. H. F. Wickham. 



This is the smallest species of the genus known to me from the 

 United States, and occurs in the subtropical extreme southern 

 limit of the State of Texas. It can be readily determined by the 

 characters given in the table. A single male. 



P. impressipennis. — Slender, the elytra and abdomen quite depressed; 

 entire body, legs and antennse very pale rufo-testaceous and perfectly uniform 

 in color, polished and subimpunctate; pubescence moderate in length and
