Alabama, Prof. Haldeman; Pennsylvania, Rev. D. Ziegler. A very beautiful and dis- 
tinct species. This and the next differ from those of the previous division by the metas- 
ternum being almost flat, while the prosternum is deeply sulcate, and the first segment 
of the abdomen is moderately so. The under surface is coppery, densely and coarsely 
punctured at the sides, nearly smooth, or sparsely punctured at the middle. The middle 
tibize are entirely straight in both sexes. The head has a V shaped callus between the 
eyes and two occipital ones with an intervening channel. 
ll. D. spreta, minus elongata, cinereo-zenea, pruinosa, thorace latitudine sesqui breviore, ad medium latiore, 
lateribus antice rotundatis postice sinuatis, inzequali, rude punctato, callis nitidis ornato, medio polito, sulco dorsali 
antice profundo, postice subbiseriatim punctato, elytris dense punctatis, sutura elevata subleevi variegata, interstitiis 
callis oblongis obscuris elevatis ornatis, postice oblique attenuatis paulo prolongatis, bidentatis. Long. -60—-66. 
Mas segmento ventrali ultimo tridentato, dente medio breviore lato truncato. Femina seemento ventrali ultimo 
tridentato, dente medio acuto.

Middle States, not common. I incorrectly placed Melsheimer’s references as synonyms 
to the next species in my index to Laporte and Gory’s species, (Proc. Acad. 1857, 7,) 
being deceived by the wretched description of these last mentioned authors. The front 
between the eyes is marked with a smooth concave callus in the middle and a smaller cne 
each side, forming an irregular elevated line: the thorax is deeply impressed each side be- 
hind the middle, and the surface is very uneven at the sides: the external costs are irre- 
gular and interrupted, and the dorsal canal is deeper at the apex; the smooth costee limit- 
ing it are broad. The middle tibie are straight in both sexes. The under surface is 
coarsely and densely punctured at the sides, nearly smooth in the middle: the metaster- 
num is scarcely channeled, and the broad deep groove of the prosternum is coarsely punc- 
tured. 
This species has a more robust form than the others of group B, being proportioned al- 
most as D. punctulata, but differs from those of group C by the strongly bidentate elytra.
