In the subgenus Stephanocleonus there are indications of several 

 other species within our territories, but the material is so limited 

 that they cannot be advantageously defined at present, especially 

 in the absence of the unique type of c7-isiatiis. It is a question 

 whether our species should be placed in Stephanocleonus or Plagio- 

 graphus, but this is a matter of but slight importance as the differ- 

 ence between these subgenera appears to be very inconsiderable. 



The above table is somewhat unsatisfactory, owing to my ina- 

 bility to study the orginal types of some of the more inadequately 

 described species, such as californicus and modestus. There seems 

 to be but little doubt, however, that prsejMens is the same as 

 trivitattus, as the size of the body and ornamentation of the elytra 

 vary remarkably in the ample series before me. 



A number of specimens collected in Arizona and Southern Cali- 

 fornia are referred to sparsus, although the prothorax is almost
