PIROTA Lee. 



The fasciate species allied to mylabrina can be very readily 

 divided into two groups depending upon the form of the last joint 

 of the maxillary palpi, some of the species having this joint but 

 slightly modified in the male, while in others it becomes large and 

 much deformed. The six species known to me may be separated 

 as follows: — 



Terminal joint of the maxillary palpi in the male very large, strongly trans- 

 verse. 

 Basal antennal joint unusually long, pale ; apical fascia of the elytra obso- 

 lete postica 



Basal joint short ; elytra with three fasciae. 



Basal joint of the antennae pale ; femora and tibiae fiavate with the apices 

 black mylabrina 



Basal joint black ; legs and entire under surface black ; middle elytral 

 fascia much more elongate, the apical one reduced to a narrow border. 



engelmanni 

 Terminal joint of the maxillary palpi not greatly modified in the male, small 

 but obliquely pyriform, rapidly pointed and attached more or less axially 

 to the third joint which is shorter and more transverse than in the female ; 

 terminal joint in the female not oblique, slender, truncate at apex. 

 Basal joint of the antennse entirely or in great part pale ; elytra rather 

 strongly punctate, the apical piceous area not attaining the apex but 

 separated therefrom by a narrow pale border, often completely obsolete. 



punctata 



Basal joint black ; elytra finely punctate, the apical piceous area much 



larger, always attaining the apical margin. - 



Elytra densely punctate and more or less dull ; antennae (male) with the 



third joint very slender, distinctly longer than the fourth ; base of the 



head more or less piceous terminata 



Elytra more sparsely punctate and polished ; antennae (male) with the 

 third joint much shorter than the fourth COiiciillia 



Mylabrina Chev. as above defined does not occur within the 

 limits of the United States, and the specimens heretofore so iden- 

 tified are resolvable into the two species defined above under the 

 names terminata Lee. and concinna. The definition of mylabrina 

 is taken from the original description of Chevrolat, in which it is 

 stated that the terminal joint of the maxillary palpi is "fortement 

 en hache, tres-epais," which would ally it closely to engelmanni and 

 insulata. 



P. punctata n. sp. — Pale testaceous, the elytra still paler and more 

 fiavate ; antennae black except the basal joint ; legs testaceous, the tarsi and
