274 GEO. H. HORN, M. D. 



thorax with very few punctures. Elytral punctures very coarse, forming quite 

 regular striae, merely a little confused behind the the scutellum. Length .26 

 inch ; 6.5 millim. 



Male. — Anterior and middle tarsi with rather long hairs beneath. Third ventral 

 segment rather densely punctured at middle, more sparsely at the sides, fourth 

 and fifth segments with a short transverse row of closely placed, recumbent 

 bristles at middle. Last ventral segment with two submarginal setigerous punc- 

 tures on each side. The third and fourth ventral segments have also a series of 

 coarse punctures, forming an arcuate row extending from side to side, each punc- 

 ture bearing an erect seta. 



Occurs in Georgia. 



P. < 'ron k hi I ti Horn, Trans. Am. Ent. Soc. 1S67, p. 151.— Body beneath 

 rufo-piceous, above piceous. Head and thorax very sparsely punctulate. Elytral 

 sculpture nearly obsolete, but with one or two large punctures in the post-scutel- 

 lar region. Length .32 inch ; 8 millim 



Male. — Characters as in excrucians. 



The post-scutellar punctures represent the row of dorsal punctures of auguntata. 

 Collected in Owen's Valley, California. 



P. Behrensi Horn, Trans. Am. Ent. Soc. 1870, p. 76. — Body beneath rufo- 

 piceous, above piceous. Head and thorax sparsely, but quite distinctly, punc- 

 tured. Thorax obsoletely subcarinate at middle posteriorly. Elytra with coarse 

 punctures forming striae at the sides, but rather irregular at middle. There is no 

 indication of a dorsal series of punctures. Length .38 inch ; 9.5 millim. 



Male. — Characters as in excrucians. 



Female. — Third ventral coarsely and densely punctured at middle, less densely 

 at the sides, fourth and fifth segments without the short transverse row of bristles. 

 Last ventral with four submarginal setigerous punctures on each side. 

 Occurs in the San Joaquin Valley, California. 



P. aiiiinslalsi n. sp. — Elongate, parallel, castaneous, shining. Head with 

 very few punctures near the occiput. Thorax a little more than twice as wide as 

 long, narrowed in front, sides slightly arcuate, margin narrowly explanate, ex- 

 cept near the hind angles, angles of thorax rounded, disc moderately convex, 

 median line finely impressed, surface with a few rather coarse punctures at mid- 

 dle, fewer and less evident near the sides, the extreme margin plurisetose. Elytra 

 elongate, parallel, as wide as the thorax, surface sparsely punctate, the punctures 

 irregularly placed on the disc, but forming vague striae near the sides; about one- 

 fourth from the suture is a series of coarse dorsal punctures about ten in number 

 bearing short setae, lateral margin sparsely fimbriate. Body beneath paler than 

 above, smooth and shining. Third ventral segment at middle densely submuri- 

 cately punctured, fourth and fifth segments with a transverse row of short setae at 

 middle, the last ventral with two large setigerous punctures near the margin on 

 each side. Length .30 inch ; 7.5 millim. PL IX., fig. 6. 



The specimen before me is a male, and the characters given above for 

 the abdomen are sexual. In shape this species is fully three times as 

 long as wide. By its parallel elytra it approaches P. Behrensi, Horn, 

 which has not, however, any trace of the dorsal series of setigerous punc- 

 tures on the elytra.
