522 TRANSACTIONS OF THE 



basal joint of the antennae. In the size of the eyes it differs 

 greatly from Megacephala, also in the circumstance that the 

 basal joint of its labial palpi is altogether concealed by the men- 

 turn : but it agrees with this genus in form, and is probably [410] 

 more closely related to it than Manticora. Still, however, as it 

 does not agree with any known group, it may perhaps be proper 

 to construct a genus for its reception. 



MEGACEPHALA Latr. 



M. CAROLINA Fabr. — This species is certainly found in the 

 southern part of the Union : I have an individual that was taken 

 in New Orleans ; it varies a little from the West Indian speci- 

 mens in being less deeply sculptured. 



CICINDELA Linn. 



1. C. UNiCOLOR Dejean. — This species appears to have an ex- 

 tensive range. I received a specimen from Dr. Pickering of 

 Massachusetts, and I found another in Florida. It varies in 

 having a slight touch of white on the tip of the elytra. 



2. C. MARGINATA Fabr. Syst. Eleut. 1, 241, No. 48. Dejean 

 has described this species under the name o^ variegata, Sp. Gen. 

 1, 84 — see also vol. 2, 414. 



3. C. UNIPUNCTATA Fabr. — Varies in having a very small ob- 

 scure yellowish spot, half way between the ordinary spot and the 

 tip, on the margin. 



4. C. VULGARIS Say, Trans. Amer. Philos. Soc. 1818. Since 

 described by Dejean under the name of ohliquata, Sp. Gen. 1, 

 72, but corrected vol. 2, Supp. 414. 



5. C. HIRTICOLLIS Say, Trans. Amer. Philos. Soc. 1818. Since 

 described by Dejean with the name of rej^anda, Sp. Gen. 1, 74, 

 but corrected vol. 2, 414. 



6. C. DORSALis Say, Trans. Amer. Philos. Soc. 1818. Since 

 described by Dejean with the name of signata, Sp. Gen. 1, 124, 

 but corrected vol. 2, 414, Supp. ; and on page 42G of the same 

 Supplement he describes another species under the name of dor- 

 salis, which, however, will of course be changed, as mine has the 

 priority.
