Fcronia obcsa Say, which resembles the latter in form, and is 

 a larger species than F. impuncticollis, but so much like it as 

 hardly to be distinguished, belongs, with it, to Amara and is 

 destitute of the triple spine. 



HARRIS TO HENTZ. 



MILTON, June 17, 1828. 



Buprestis femorata Fabr., differs from the species marked 

 characteristica? Herbst, in many respects. The distinctive 

 characters of B. femorata appear to be, face plain, with two 

 large metallic impimctured raised spots ; body slightly convex, 

 the impressed portions of the elytra metallic, distinctly and 

 densely punctured, serratures of the elytra minute. 



B. characteristica? Face divided by a transverse line be- 

 tween the eyes, the inferior portion below the level of the supe- 

 rior, which seems to lap on it like a cap; metallic facial spots 

 very small or obsolete. Body more dilated, more depressed 

 than in B. femorata', elytral impressions not very distinctly 

 metallic, nor so densely punctured; serratures very obvious, 

 especially at tip. Color tinged with purplish brown. The 

 first character alone, viz. : the division of the face by a trans- 

 verse line, is sufficient to separate the two insects. 



I have examined Tdephorus bilineatus, and observed that the 

 maxillae and lingua were so soft as to yield on pressing the 

 abdomen, and jut out into caruncles from what appeared to be 

 a crowd of the fluids ; whether these parts are susceptible of 

 voluntary dilatation I cannot determine. My friend, Mr. 

 Leonard, has promised' to send me a quantity of duplicates 

 from his parish in Dublin, N. H., near the Grand Monadnoc 

 Mountain. Many among those which I have already received 

 from him are entirely new to me. Mr. Leonard is indefatig- 

 able in studying the habits of insects, and very successful in
