174 Coleopterological Notices, III. 



tips of the femora and tibiae black ; under surface variegated with black and 

 testaceous, the abdomen banded ; integuments polished. Head immaculate, 

 finely, sparsely punctate ; eyes moderate ; antennae slender, two-fifths as long 

 as the body in the male. Prothorax slightly elongate, narrowed toward apex 

 from the middle, the apex three-fifths as wide as the base ; sides parallel in 

 basal half; disk very finely, sparsely punctate, with two discal rounded spots 

 as in postica but without trace of lateral spots. Elytra parallel, strongly and 

 rather sparsely punctured, the scutellar spot small, elongate-oval, widely 

 separated from the humeral spot which is narrow and linear, extending nearly 

 to basal third ; second fascia slightly behind the middle, rather short, strongly 

 bilobed ; subapical spot lunate. Length 15.0-19.0 mm. ; width 4.2-6.0 mm. 



Western Texas. 



The three specimens before me are quite homogeneous as regards 

 the form and extent of the first two fasciae, but the subapical band 

 is totally wanting in one, and in another it exhibits such a form as 

 to indicate the probability of its being prolonged forward exter- 

 nally in more fully maculate examples, so as to be united to the 

 external lobe of the median spot. The middle spot is so strongly 

 bilobed that it is possible that it may be longitudinally divided into 

 two spots in less fully marked specimens. 



P. concinna n. sp. — Testaceous ; under surface maculate with black ; 

 antennae black throughout ; legs as in punctata; elytra broadly trifasciate, the 

 black predominating nearly as in terminata; integuments highly polished. 

 Head minutely, very sparsely punctate ; eyes moderate ; antennae a little less 

 than two-fifths as long as the body ; neck with a small evanescent black spot 

 in the middle of the upper surface. Prothorax distinctly elongate, narrowed 

 in front from a little behind apical third, the apex nearly three-fourths as 

 wide as the base ; sides parallel ; disk minutely, very sparsely and irregularly 

 punctate, feebly impressed in the middle near the base. Elytra parallel, three 

 times as long as wide, each with the four usual fine feeble subcostiform lines, 

 the third joining the marginal behind the humeri ; disk finely, generally 

 somewhat sparsely punctate, the basal spots always broadly united. Length 

 11.5-18.0 mm. ; width 3.0-5.0 mm. 



Western Texas. 



This species is closely allied to terminata but is well distinguished 

 by its more polished and sparsely punctate elytra, and by its 

 antennal structure; it is still more definitely separable from that 

 species by the form of the maxillary palpi of the male, the latter 

 being more elongate and with the terminal joint much less exter- 

 nally developed toward base in terminata than in concinna. 



Most of the specimens before me have the head and pronotum 

 maculate as in terminata, but two of them have these parts almost
