cords it from Massachusetts and Maryland, and adds that " it is not 

 uncommon in all the States north of Virginia." I have recently- 

 seen an example in the Cornell University collection, that was taken 

 near Ithaca, N. Y. 



Var. pulchellus Westw. — I have a typical example of this variety 

 from Baton Rouge, Louisiana, taken in May, and have seen another 

 from Del Rio, Texas, taken by Prof. Wickham in June. This 

 variety is much larger than fimbriatus, and is of a deep blue black 

 color marked with orange. 



Var. violaceus Say. — Prof. Osborn has sent me for study one indi- 

 vidual of this variety taken by Prof. Wickham at Del Rio, Texas, 

 in June, and Dr. Uhler records it from Pennsylvania, Georgia, 

 Florida and Texas. 



*Var. persoaatas Gerraar. — Dr. Uhler records this variety from 

 Pennsylvania. I have not yet seen it. 



Stiretrus auchorago as a species has been recorded from about all 

 the southei-n States, and as far north as Iowa and Massachusetts. 

 Southwardly it extends through Mexico to Panama. Two of the 

 varieties are figured on Plate I of the Biologia. 



Oplomus (lichrous H. S. 



Another very variable southern species of which I possess exam- 

 ples taken in Nogales, Arizona, in August, by Prof. Wickham, and 

 an individual taken in a greenhouse in Philadelphia. This species 

 in all its varieties may be distinguished from its congeners by hav- 

 ing the anterior edge of the prosternum produced in a rounded 

 lamina either side of the base of the rostrum. The head is narrowed 

 at the apex, and in the male the cheeks are prolonged, contiguous, 

 and strongly depressed before the apex of the tylus. 



Genus PERII.L.U^i Stal. 

 Form somewhat depressed; pronotiiin scarcely raised above the level of the scu- 

 tellum conflueiis. 



Form more convex ; pronotum quite strongly convex above the base of the scu- 

 tel 1 u m 1 . 



1. Anterior femora with a blunt tubercle in place of a spine exaptiiK. 



Anterior femora with a stout spine 2. 



2. Surface finely and closely punctured, anterior margin of tlie sixth ventral seg- 



ment broadly rounded ; antennae black, with metallic-green reflec- 

 tions spleudidiis. 



Surface coarsely punctured, anterior margin of the sixth ventral segment quite 

 distinctly produced in an angle more or less obvious -3.
