pronotum. The tooth on each side of the clypeal emargination is 

 variable in length, sometimes becoming nearly obsolete. The tooth 

 on the anterior tibia is variable in size, but is always acute at the 

 apex. The length is from 7 to 10 mm. 



LeConte described this species from a single male collected at 

 Santa Fe, N. Mex., by Mr. Fendler. Horn (1886) states that contigua 

 differs from cuprascens in having the clypeal teeth well marked and 

 the tooth on the anterior tibia of the male rather broad and not very 

 acute at the tip. These characters are variable and cannot be used 

 for separating the two species. He also states that the tooth on 

 the tibia is below the middle in contigua and one-third from the apex 

 in cuprascens, but this statement is incorrect, as in all the specimens 

 examined the tooth is one-third from the apex. 



The writer is unable to find any character satisfactorily to separate 

 cuprascens from semisculpta in the key, and there will be some diffi- 

 culty in separating these species except by locality. Chrysobothris 

 semisculpta seems to be confined to the Pacific coast. The specimens 

 of cuprascens differ from those of semisculpta from Oregon and 

 California in usually having the antenna wider and nearly equal in 

 width to the apex, the callosity on each side of the last visible ab- 

 dominal sternite more strongly elevated, and the male genitalia not 

 so strongly expanded at the middle, with the soft lateral lobe on each 

 side about one-fifth shorter than in semisculpta. The writer is un- 

 decided as to whether these two species are distinct, but it seems ad- 

 visable to retain them until their habits and distribution are better 

 known.
