298 [April, 



Fort Laramie, Nebraska. The first fascia proceeds from the middle of the 

 humeral spot, runs obliquely inwards, and is dilated into a quadrilateral spot 

 with elongated angles ; the second fascia is just behind the middle, and is deeply 

 emarginate anteriorly; neither attain the suture. The anterior black band of the 

 thorax covers nearly half the surface. In one specimen nearly the whole abdo- 

 men is ferruginous. 



56. H. p u 1 c h e r, ovalis postice magis attenuatus, parum convexus, subtilis- 

 sime puoctulatus, glaber, ferrugineus, thorace antice late, ad basin anguste nigri- 

 cante, lateribus tenuiter marginatis, elytris nigris macula humerali quadrata, 

 fusciis anguiatia duabus, margine apiceque rufo-testaceis, stria suturali nulla, 

 serie punetoruin dorsali parum distincta. Long. -13. 



One specimen from Alabama, collected by Mr. Hentz, was given me by Prof. 

 Haldeman. The color and markings are almost as in the preceding ; the body, 

 however, is broader and more obtuse in front and more acute behind ; the sutu- 

 ral stria is not visible, and the color beneath is ferruginous, though darker than 

 the red of the feet, head and thorax. 



58. H. difformis, longior, obconicus, glaber, ferrugineus, thorace ob- 

 scuriore, disco subconvexo parce punctulato, distinctius ad latera et basin, late- 

 ribus marginatis cum elytris angulum haud formantibus, his minus dense punc- 

 tatis, fuscescentibus ad basin pallidioribus. Long. -25. 



Mas antennarum articulis 4to late, 3io et 5to anguste dilatatis. 



One immature specimen from Georgia. Resembles H. conoideus, but is larger, 

 and the thorax would never become black. The punctures of the elytra are equal 

 in size, while in H. conoideus two sizes are intermixed; the dilated third joint 

 of the antennas is also narrower than the fourth, while in the other species men- 

 tioned they are of equal breadth. 



59. H. sira ilis Kirby. This may be identical with the European H. picipes, 

 but I have not been able to compare them. I must consider, however, that there 

 are reasons why the following species should not be considered as H. lineellus of 

 Europe, which is admitted to be a female variety of H. picipes. 



60. H. pi cat u s Kirby. Of this species I found both sexes at Mackinaw, 

 and on the north shore of Lake Superior. The dull and finely punctured female 

 hardly differs from the preceding, but the coarsely punctured male has no dis- 

 tinct elytral striae. Otherwise there is no special difference. 



62. H. turbidus, ovalis convexus, piceus, nitidus, capite pedibus thorace- 

 que fere testaceis, hoc margine apicali et basali infuscato, elytris parum angus- 

 uore, lateribus obliquis rectis marginatis cum elytris angulum hand formantibus, 

 antice parce punctulato, postice punctata, elytris modice punctatis, versus latera 

 rufescentibus. Long. -11. 



One specimen from Massachusetts was given me by Mr. Zimmerman. Resem- 

 bles in characters H. suturalis, but is broader and more convex, and the elytra 

 are less densely punctured The color is more reddish, there is no diseoidal 

 spot on the thorax, and the suture of the elytra is not paler. 



67. H. patruelis, longior ovalis parum convexus, nitidus subtus niger, an- 

 tennis pedibus corporeque supra testaceus, fere aequaliter confertim punctatus, 

 occipUe, thoracis basi apice et medio, elytrisque postice ssepe subinfuscatis, tho- 

 race eh tris conspicue angustiore, lateribus obliquis rectis anguste marginatis 

 cum eiyris angulum formantious. Long. -15. 



Fort Laramie, Nebraska Similar in form to the Californian H. lutescens, but 

 less convex, lighter colored, and with the sides of the thorax a little longer and 

 almost entirely straight, and the elytra more coarsely punctured. 



69. II. n u b il u s, longior ovalis, parum convexus, nitidus, subtus niger, an- 

 teonis pedibus corporeque supra testaceus, aequaliter subtile dense punctatus, 

 elytris lineis quatuor pone medium confusis nigro-piceis signatis. Long. -17. 



Fort Laramie ; found also in Illinois by Mr. Willcox. Still longer than H. pa-
