200 GEO. H. HORN, M. D. 



Occurs principally in the Gulf States, Vjut I have seen specimens from 

 Michigan and Kansas. 



P. fusiforinis Mels. — Body moderately elongate, fusiform, black, shining ; 

 elytra red, legs testaceous; antennse slender, as long as the head and thorax, pi- 

 ceous, two basal joints pale, joints all longer than wide ; head rather elongate oval, 

 narrowed behind the eyes and smooth; thorax oval, wider than the head, very 

 obviously narrowed in front, not longer than wide, convex, very shining, dorsal 

 punctures moderately deeply impressed and equidistant; elytra scarcely wider 

 than the thorax, conjointly nearly square, shining, moderately closely punctate, 

 sparsely pubescent ; abdomen shining, sparsely coarsely punctate; beneath a little 

 more closely punctate than above. Length .20 inch ; 5 mm. 



Male. — Anterior tarsi moderately dilated; last ventral triangularly emarginate, 

 surrounded by a triangular impression. 



Female. — Anterior tarsi scarcely at all dilated ; last ventral entire. 



The characters given in brief in the table are the striking points of 

 difference between this species and its close allies. 



Occurs in the Middle States and Canada, westward to Colorado. 



p. fulTipes Fab. — Form rather parallel, black, shining; elytra red, legs tes- 

 taceous; antennae as long as the head and thorax, piceous. three basal joints tes- 

 taceous, joints 5-1(1 as wide as long ; head oval, scarcely narrowed behind the eyes, 

 hind angles smooth ; thorax very little wider than the head, slightly longer than 

 wide, scarcely at all narrowed in front, dorsal punctures moderately, impressed, 

 equidistant; elytra a little wider than the thorax, conjointly a little wider than 

 long; surface moderately shining rather sparsely punctate, sparsely pubescent; 

 abdomen sparsely punctate, the punctures rather coarser than those of the elytra; 

 beneath more finely punctured than above. Length .26 inch ; 6.6 mm. 



Me-le. — Anterior tarsi moderately dilated; last ventral segment with a feeble 

 triangular emargination surrounded by a triangular impression. 



Female. — Anterior tarsi very narrowly dilated; last ventral entire. 

 In comparing certain specimens sent to me by Fauvel under the name 

 Horni., I am unable to find differences warranting specific sejiaration. In 

 some of the native specimens the elytra are possibly a little more closely 

 punctate and less shining. 



Occurs in Canada, Mass., Mich, and N. Y. From Kirby's notes 

 (Faun. Bor. Am.) it is impossible to tell whether he had this species or 

 the preceding before him in quoting ywZt'fJDe.s, as both occur in Canada. 



P. OCCidentalis n. sp. — Form moderately robust, black, shining; elytra 

 clear red; legs piceous or piceo-testaceous; antennae longer than the head and 

 thorax, piceous, joints all longer than wide, 8-1 fl conspicuously shorter than those 

 which precede ; head sub-quadrate % or orbicular 9 » hind angles sjiarsely punc- 

 tured ; thorax broader than the head, as broad as long, very little narrowed in 

 front, dorsal punctures moderate, rather closely approximate, equidistant ; elytra 

 a little wider than the thorax, conjointly nearly square, disc rather flat, shining, 

 moderately densely punctate, very sparsely pubescent ; abdomen more finely and 

 closely punctured than the elytra; beneath more coarsely punctured than above. 

 Length .28— .30 inch : 7—7.5 mm.
