scutel triangular, green : elytra with three or four elevated longi- 

 tudinal lines on each, and three impressed reddish-cupreous spots 

 placed one at the base, one rather before the middle, and the 

 third behind the middle ; edge minutely serrate. 



Length seven-twentieths of an inch. 



I have been under the necessity of applying another name to 

 this insect, as that given by Mr. Melsheimer is preoccupied by 

 a different species. We found this during our expedition to the 

 Missouri, and it is also an inhabitant of the Atlantic States. 



[Belongs to Chrysohothris. — Lec] 



5. B. GiBBicoLLis. — Black ; elytra each with two large yel- 

 low spots. 



Inhabits Arkansa. 



Body black, with a slight violaceous tinge, and with very nu- 

 merous very short hairs ; punctured : thorax gibbous, arising into 

 a very obtuse obsolete tubercle each side above ; covered with 

 dense hair ; posterior edge rectilinear, angles rounded : scutel 

 orbicular : elytra punctured, destitute of striae ; posterior edge 

 finely serrated ; tip entire; a very large [162] elongated spot 

 extending from the base to the middle, and a smaller orbicular 

 one towards the tip : venter violaceous. 



Length less than three-tenths of an inch. 



A very pretty insect; but a single specimen was procured. 

 Can this be the B. volvulus Fab. ? 



[A species of Ptosima subsequently described as P. luctuosa 

 Glory. — Lec] 



6. B. GRANULATA. — Glreen, granulated; elytra with an ele- 

 vated line, and serrodentate at tip.

Body cylindrical, olive-green, granulated : head punctured,

 tip rounded : eyes whitish, with a black oblong moveable pupil : 

 thorax with an oblique indented line each side, and a longitudinal 

 dorsal one ; basal edge sinuated ; scutel transversely elongated, 

 with an impressed transverse line behind : elytra scabrous or
