15. I*, bimaciilatiis Melsh. — Oblong, parallel, robust; antennae, legs and 

 lower surface rufous; above black or piceous, the humeri and apical third or 

 fourth of the elytra rufous. Antenna; shorter than the length of the body, sec- 

 ond joint two-thirds the length of the third, the outer joints about twice as long 

 as wide in the male; second joint subequal to the third, the outer ones scarcely 

 one-half longer than wide in the female; joints obconical in both sexes. Eyes 

 moderate, not more prominent than the sides of the prothorax ; front about twice 

 as wide as their vertical diameter in the female, a little narrower in the male. 

 Hairs of the upper surface generally dark in color, the elytral setae moderately 

 stout, the longer ones of the interspaces about equal to the distance from the 

 suture to the second stria; the strial setae shorter and more inclined, as usual. 

 On each elytron is a conspicuous, somewhat irregular posthumeral fascia of dense 

 white, appressed, squamiform hairs, and a similar narrower fascia bordering the 

 apical rufous area; there is also a small dot of white hair on the fourth inter- 

 space, close to and just behind the inner end of the anterior fascia, and another 

 on the third interspace, half way between this and the posterior fascia. Beneath 

 moderately pubescent, the metasternum coarsely, sparsely punctate. Legs rather 

 short, the first joint of the hind tarsi barely equal to the next two united. 

 Leugth 2-2.8 mm. 



I have seen specimens from New York, Pennsylvania, Michigan 

 (Ann Arbor), Missouri, Kansas (Salina), Florida (Crescent City). 

 Apparently a rare species in the northern States, the larger number 

 of specimens seen coming from Texas. 



Frontalis Melsh. is quite surely the male of this species, and M. 

 Pic has recently described it again under the name rubroajjicuiits. 

 The remarkably stout form which is, however, not in the least ven- 

 tricose, the peculiar coloration and the conspicuous white fascia? at 

 once distinguish this from all other species. 



16. P. tumitlu* n. sp. — Oblong, piceous; legs and antennae rufous. Head 

 granulate and with fuscous hairs; eyes very large and prominent; front a little 

 narrower than the vertical diameter of the eye. Antenna? rather slender, nearly 

 as long as the body, at least in the male; outer joints nearly four times as long 

 as wide, each slightly increasing in width from base to apex. Prothorax much 

 narrower than the width across the eyes, disk strongly compressed and elevated 

 in front, moderately strongly constricted behind, surface granulate and rather 

 densely clothed with long erect hair, which is predominantly fuscous in color at 

 the middle, becoming paler at sides. Elytra parallel, about twice as wide as the 

 prothorax ; strial punctures moderate, becoming finer at apex ; interspaces a little 

 wider than the stripe on the disk, each with alternating, shorter and longer erect 

 setae, which are scarcely at all recurved, and vary in color from fuscous to ochra- 

 ceous, the darker color prevailing on the disk ; setae of strial punctures shorter 

 and less erect. The longer hairs of the interspaces are about equal in length to 

 the distance from the suture to the third stria, the shorter ones two-thirds as 

 long. The discal portion of the base, the sutural region, and the lateral margin
