me from the British Museum Collection, identified by 

 Jacoby who had seen Suffrian's type. Renidens Lee. 

 and laevicollis Bowd. are not distinct from these Jacobyan 

 specimens. 



dilatatus. Confused with siibfasciatiis in all American col- 

 lections. A type recently sent me by Dr. Taschenberg 

 enables me to fix the species with certainty; it is thus 

 far very rare in collections. 



bajulus. Identified from specimens sent me by Mr. Cahan 

 from the British Museum Collection and determined by 

 Jacoby from Suffrian's type. 



charaderisticus. Recently identified from Suffrian type. 



oculatus. A type sent to Bowditch seems not to be separable 

 from sobjinus Hald. 



spumarius. A male type from the Suffrian Collection was 

 sent to Bowditch, and lately a female type to me. An 

 interval of six years has dulled my remembrance of the 

 former and I do not feel sure that the two are identical. 

 I am Inising the species on the female type but I feel that 

 there is still some uncertainty here. 



wipurus. Identity established from type. 



melanostictus. Identity established from type. 



peccans. Identity established from type. 



xanthias. Identity established from type. 



obsoletus. Of this we have seen no type, and my interpre- 

 tation is open to doubt. As I have identified it, this is 

 the species which Haldeman erroneously took for the 

 tridens of Melsheimer. 



conformis. Identity not established with certainty. I 

 have accepted as this species an example so labeled in the 

 LeConte Collection. 



umhraculatus. Specimens from our Mexican Ijorder states 

 are identical with Mexican examples in the National 

 Museum Collection so labeled ))y Schwarz. Others from 

 the British Museum identified as umbracidatus by Jacoby 

 appear to be a nearly immaculate form of the same thing. 



litigiosus. Well known for many years, though the name 



has been somewhat promiscuously applied in collections. 



1858. Suffrian— Linn. Ent. XU, pp. 401, 404, 406— describes 



the following:
