AND EASTERN NEW MEXICO. 25 



H. plurili;;ata, pallicle flava, elougata, tborace latitudine sesqui breviore, fere obsolete punctu- 

 lato, guttis nigris quatuor, lineolaque dorsali versus basin ornato, lateribus rotundatis marginatis, 

 elytris subtiliter parce punctulatis, sutura, vitta discoidea apicem haud attingente, alteraque juxta 

 marginemuigris; tibiis ad apicem, tarsisque fuscis, anteunis nigro-piceis, articulis tribus primis 

 flavis supra iufuscatis. Long. -32. 



Kansas and Texas. Also allied to H. altemata, but narrower and with a less 

 transverse thorax. Both this and the preceding, as well as the next species belong 

 to Chevrolat's division (called genus by some authors) Disonycha. 



H. cervicalis, ovalis, pallide flava, capite, antenuis, pedibus, elytrisque nigris, his punctulatis 



subalutaceis ; thorace subtilius marginato, Inevi. Long. -2. 



Kansas and Georgia. Very similar to H. collaris, but rather stouter than that 

 species, and distinguished by the uniform pale-yellow color of the under surface. 



H. seiuicarbonaf a, ovalis convexa, fusco-atra, elytris opacis subtiliter punctatis, thorace parce 

 punctulato, flavo, ad basin versus angulos posticos rectos sinuato, clypeo, abdominis segmento 

 ultimo veutrali, coxis femoribusque flavis ; antennarum articulis 1 — 3 suiiitus, tibiisque posticis ad 

 basin flavis. Long. -24. 



Santa Fe : one specimen : Mr. Fendler. Belongs to the division named Disonycha 

 by Chevrolat, and resembles in appearance H. collaris Fabr., but is broader, having 

 the form of H. cervicalis; it is readily distinguished from both by the dull elytra 

 and different arrangement of the colors beneath. 



H. ambiens, elongata, convexa, cyanea nitida, thorace virescente, punctulato, ad basin late rotun- 

 dato, ante basin profuude transversim sulcato, sulco versus angulos profundiore, elytris subtiliter 

 punctulatis, carina submarginali distincta, postice curvata et versus suturam obliterata. Long. -22. 



Santa Fe: Mr. Fendler. Differs from H. sulpUcata in the smaller size, and by 

 the more elevated submarginal costa of the elytra being curved behind. It nearly 

 resembles a nondescript species from New Hampshire [H. alni Harris), but the 

 thorax is more convex, and the elytra more deeply punctured, while the curved 

 portion of the costa is less prolonged towards the suture; in both tlie elytra are 

 broadly sulcate about the middle, just within the costa. 



H. Sllbplicata, elongata, obscure cyanea, parum nitida, thorace latitudine paulo breviore, subtiliter 

 punctulato, lateribus rectis augulis omnibus distinctis, postice fortiter transversim sulcato, elytris 

 parce punctulatis, plica submarginali minus elevata versus apicem sensim obliterata notatis. 

 Long. -25. 



One specimen : found in Platte river valley. Belongs to a numerous group of 

 the division Graj)todera Cherv., having an elevated fold parallel with the outer 

 margin of the elytra ; this fold in the other species is, howevei', much more elevated 

 and curved posteriorly towards the suture. 



H. piinctipeiini^, elongata, Isete viridi-Eenea, thorace antrorsum angustato, latitudine sesqui 

 breviore, lateribus late rotundatis, vix subtiliter punctulato, postice transversim tenuiter obsolete 

 sulcato, elytris thorace paulo latioribus, distincte licet subtiliter punctatis, antennis nigris. 

 Long. -2. 



Kansas and Santa Fe. Specimens from New Mexico were collected by the late 

 Richard C. Kern, Esq., and were given to me b}^ Prof. S. S. Ilaldeman. This is a 

 Graptodera of slender form, and is readily distinguished by the distinctly punctured 

 elytra, and by the slight posterior impression of the thoi'ax.
