 tawny yellow ; the latter with a black sutural line widen- 

 ing towards the tip : head, antennae^ body and legs black- 



Len^rth from 25 to 28 hundredths of an inch. 



Thorax rough, with deep and dense punctures ; scutel

On the 14th of July, 1833, I found full grown larvae 

 of a Hispa in the leaves of Solid ago IcEvigata, 'a 

 plant abounding upon the margins of our salt marshes, 

 where I was led to look for these larvae in consequence 

 of having discovered Hispa vittata, in the perfect state, 

 in the axils of the leaves, during the month of Septem-

 sured 40 hundredths of an inch in length : 

 they were more elongated than the two 

 preceding species, more acuminated before 

 and behind, and the lateral tubercles were 

 much more prominent. The body was 

 whitish, the head and feet dusky or black-

 ment was marked with a transversely oval 

 brown spot, near the anterior part of which 

 were two black dots. The last segment was brownish 

 above. The sides of the rings were prominent, tooth- 

 like, pointing backwards, and tipped with small, acumi-

 the body as m other species. The pupae bore a gen-
