smaller variety (or species) is found in Italy. Now what 

 Fabricius meant hy fascia or striga flexuosa may be discovered 

 by other descriptions of his, as of Cie'mdela flexuosa and lurida. 

 C. flexuosa described from Olivier, who has figured it (as well 

 as trifasciata and lurida'), has the intermediate band irregularly 

 bent, as in 0. vulgaris. See Olivier and Dejean, Iconogr., I, 

 pi. V, fig. 5. So also lurida has a nearly similarly formed, 

 intermediate band ; and in both of these Fabricius describes it 

 as '■'- flexuosa^ The shape you will perceive, therefore, is very 

 unlike the tortuous band of tortuosa. Secondly, the Amer- 

 ican trifasciata has its representative in Italy, according to 

 Fabricius. Illiger considered the Italian one to be sinuata 

 " without any doubt," and this has the intermediate band 

 angular and recurved, also unlike that of tortuosa.^ 



Therefore upon an examination and comparison of the Fabri- 

 cian and Olivierian descriptions and figures, I have come to 

 the conclusion that the tortuosa of Dejean is not the trifasciata 

 of Fabr. For the right understanding of the Fabrician de- 

 scriptions I find it important to refer to the works which Fab- 

 ricius published before his Systema Eleutheratorum, as they 

 often contain additional remarks that are not embodied in the 

 last. 



HAERIS TO LECONTE. 



Cambridge, Dec. 6, 1851. 



Among the insects collected by Prof. Hentz in North Caro- 

 lina, there were numerous specimens of a /Stenoco7'US (^JiJlapJii- 

 dioTi), allied to the putator of Peck, as also a few of the 

 latter species. They were intermixed, but I had no difficulty 

 in separating the species, notwithstanding their similarity and 



1 Some aiithors suppose that the Italian tnsignata 111., is the same as the Italian vari- 

 ety of trifasciata Fabr. ; the intermediate band of irisignata is also unlike that oftortti- 

 osa, and represents that of hirticollis.
