Callidium violaceum Linn. 



C janthinuiii Lee. Journ. Acad. Nat. Sciences, Phila., ser. 2, Vol. II, p. 34. 



Leconte in his remarks following the description of C. janthinmn 

 says that this and antennatuni differ from the European violaceum, 

 but I am unable to see any difference between two European speci- 

 mens of violaceum and a series of American specimens of janthinum. 



The long series before me, about forty specimens, loaned me by 

 Messrs. Davis, Frost, Leng, Shoemaker and Schott show great varia- 

 tion in form as well as sculpture of prothorax. The prothorax in 

 some specimens is rather broad, in others small ; the sides broadly 

 rounded, in others subangulate; the lateral area may be more or less 

 coarsely and rugosely punctate or more or less distinctly granulate. 

 The color of elytra may be violaceous, dark blue or greenish blue. 



This species has longer and less suddenly clubbed femora than 

 any other species. 



Messrs. Davis and Shoemaker collected a large number of speci- 

 mens at Whiteface Mt., N. Y. ; also a few at Rockaway Beach, Long 

 Island. A single specimen in the Museum collection is from Brook- 

 lyn, N. Y. Mr. Frost has taken this species at Framingham, Mass. ; 

 also at Paris, Maine, and specimens from Maine and Quebec are in 

 Mr. Davis's collection. Mr. Leng has specimens from Vermont and 

 one from Texas, which latter locality, however, is evidently a mis- 

 take. A single specimen from Stephenville, Newfoundland, collected 

 by G. P. Engelhardt, is in the Museum collection. 



Callidium texanum new species. 



Similar in form to violacentn (janthinniii) ; color dark blue, antennae and 

 under side black or piceous with scarcely a bluish tint ; femora and tibiae more 

 or less bluish. Head coarsely and subconfluently punctate ; antennae reaching 

 to about middle or a little beyond middle of elytra and nearly similar in both 

 sexes, the joints a little stouter and the last four a little longer in the male 

 than those of the female. Prothorax transverse ; sides gradually, arcuately 

 narrowing from a little behind middle to apex, more strongly narrowing to 

 base ; surface coarsely and closely punctate at middle, at sides more finely and 

 subrugosely punctate in the male, in the female the punctures at sides are 

 coarser than in the male, but still smaller than at middle. Scutellum scarcely 

 transverse and rather rugosely punctate. Elytra about two and one lialf 

 times as long as prothorax; sides parallel; apices broadly obliquely rounded; 

 surface coarsely and confluently punctate, the punctures less close near base. 

 Prosternum coarsely punctate in the male, sparsely punctate and shining in 

 the female ; intercoxal process rather coarsely, transversely strigose. Length 

 10 mm.
