NORTH AMERICAN COLEOPTERA. 115 



This species is most closely allied to discoidea but differs not only 

 in color but also in the coarser punctuation of the head and thorax and 

 the more opaque elytra. 



Occurs in Texas near San Antonio. 



P. li in balls Lee. — Body beneath yellowish. Head yellow, sparse!}' punc- 

 tate. Thorax yellow, sparsely finely punctate, two discal spots black. Elytra 

 punctate scabrous, subopaque, piceous, the entire limb yellow. Legs piceous, the 

 femora at base yellow. Length ..36 inch ; 9-10 mm. 



The elytral markings are shown on PI. 5, fig. 18. 

 Occurs in Virginia. 



P. liiieatsi Oliv. — Beneath yellowish, the sides of body maculate with pice- 

 ous, the abdominal segments piceous at base. Head reddish yellow, very sparsely 

 punctate. Thorax reddish yellow, very nearly entirely smooth, two discal spots 

 piceous. Elytra rather densely punctate scabrous, subopaque, piceous, entire limb 

 and a narrow median vitta yellow. Legs yellow; knees, tips of tibiae and tarsi 

 piceous. Length .44 inch: 11 mm. 



This species has remained unknown to us until very recently when two 

 specimens have reached me almo'S^t simultaneously from Georgia and 

 Texas. The elyti'al markings are shown by fig. 19, the Texas sjjecimen 

 having the yellow border and vitta somewhat broader. 



G. biliiieatu n. sp. — Form rather slender, reddish yellow, elj'tra paler yel- 

 low, each with two entire, narrow black vittiB. Antennae black, the basal joint 

 very little longer than the next two together. Head coarsely but very sparsely 

 punctate. Thorax elongate, parallel behind, narrowed in front, disc shining with 

 few punctures, a small black spot on each side at middle, rarely absent. Elytra 

 pale yellow, the black vittse, slender and nearly straight, surface shining rather 

 feebly punctate scabrous. Body beneath sparsely punctate and pubescent. Legs 

 reddish yellow, femora at knees, tibiae at tips and tarsi piceous. Length .28-.38; 

 7-9.5 mm. 



A pretty and neat species not resembling any other in our fauna. It 

 had been considered lineatn but this is quite a different species. The 

 elytral markings are shown on PI. 5, fig. 22. 



Occurs in Colorado and Arizona. 



P. siniiata Oliv. (Afzeliana Fab). — Head yellow with two occipital spots. 

 Thorax yellow with two discal spots. Elytra yellow with a scutellar spot and a 

 sinuous vitta piceous. Legs entirely yellow. Length about .44 inch ; 11 mm; 



This species still remains unknown to us. I have reproduced the 

 markings of the elytra as given by Olivier to assist in its identification 

 (PI. 5, fig. 23). 



Occurs in Carolina.
