29. Thaneroclerus sanguineus Say. Wis. ; Colo. 



30. Trichodes bibalteatus Lee. Tex. 



31. Trichodes apivorus Germ. var. interruptus Lee. N. J.; Pa.; Tex. 



Six specimens, all of which belong to the variety interruptus, 

 in which the dark elytral fascia are interrupted at the suture. 



32. Trichodes nuttalli Kirby. Wis. 

 33. Trichodes ornatus Say. Colo.; Oreg. 



In only one specimen out of a series of twelve are the basal 

 markings of elytra complete ; in the others the posterior prolon- 

 gation of the basal fascia is broken, the broadened portion of apex 

 remaining as an isolated maculation near suture, midway between 

 base and the median fascia ; the other fasciae show but little varia- 

 tion. 



Subfam. III. PHYLLOBAENINiE. 



34. Phylobaenus dislocatus Say. Pa.; Wis.; Ohio. 



Subfam. IV. HYDNOCERINiE. 



35. Hydnocera unifasciata Say. Pa. ; Tex. 



36. Hydnocera subfasciata Lee. Mont."; Wyo. ; Tex.; Ariz.; Cal. 



37. Hydnocera humeralis Say. N. J. ; Mass. 

 37a. Hydnocera humeralis Say. var. difficilis Lee. Mass.; Pa. 



This color variety is scarcely deserving of a name, no doubt 

 being possible as to its identity with the typical form, the two 

 being connected by intermediate forms in which the humeral mac- 

 ulations are of all manner of size and degree. The elytral sculp- 

 ture of humeralis and the two forms cyanescens and difficilis is 

 extraordinarily variable and, like the form of the thorax, gives 

 nothing of a stable nature to enable the forms to be differentiated. 



38. Hydnocera pubescens Lee. Tex. 



39. Hydnocera tricolor Schaef. Tex. 

 40. Hydnocera cribripennis Fall. Ariz. 



41. Hydnocera discoidea Lee. Ariz. 



42. Hydnocera scabra Lee. Cal. ; Ariz. 



43. Hydnocera pedalis Lee. Wis.; Mo. 



44. Hydnocera verticalis Say. Pa. ; Tex. 



This is an exceedingly variable species in coloration, and 

 especially so in regard to head and thorax ; nevertheless, in over
