A.—b. 
4. D. pugionata, xneo-cuprea, thorace latitudine paulo breviore, antrorsum a basi paulo angustato, lateribus 
parum rotundatis, rude punctato, profunde canaliculato, costisque 4 subleevibus notato, externis interruptis, seepe 
obsoletis, elytris striis punctatis, versus suturam distinctis, interstitiis spatiis lavibus nigricantibus parum elevatis 
variegatis, ad apicem valde prolongatis bidentatis. Long. -45—-54. 
Buprestis pugionata Germ. Ins. Noy., 57; (nee Laporte & Gory.) 
Pennsylvania, Maryland: Dr. Melsheimer, and Mr. J.P. Wild. A pretty little species, 
very distinct from all others by the characters above given. The sternum and first ventral 
segment are sulcate as in the others of group (A,) the last ventral segment in one speci- 
men is marked with two elevated lines more approximate than D. divaricata, butintwo 
other specimens before me, I can scarcely perceive them. The tip in the female is triden- 
tate, the middle tooth narrow, but rounded at the apex. The male is unknown to me.

5. D. mutica, longiuscula, griseo-zenea, thorace latitudine sesqui breviore, ante medium fortius angustato, 
et lateribus sinuato, fortiter, ad latera confluenter punctato, dorso canaliculato, elytris punctatis, striis internis dis- 
tinctis, interstitiis spatiis obscuris variegatis, internis nitidis parce punctatis, postice oblique attenuatis, haud pro- 
longatis, rotundatim truncatis, prosterno convexo, parce punctato, metasterno segmentoque yentrali primo sulca- 
tis. Long. -64. 
Mas segmento ultimo ventrali rectangulariter inciso, dente emarginationis brevi lato recte truncato, tiblis in- 
termediis rectis. Sexus altera latet. 
One specimen from Brooklyn, New York, given me by Mr. J. Akhurst. Differs remark- 
ably from all other species known to me; the sculpture of the elytra is exactly as in D. 
lurida.

leevi notato, medio parce punctato, sulco dorsali subinterrupto, elytris punctatis, striis versus suturam et apicem 
punctatis, interstitiis internis levibus nigro variegatis, ad apicem sensim attenuatis bidentatis, parum prolongatis.

Massachusetts to Florida. Readily distinguished from all others but the two next, by 
the freedom from any conspicuous elevations, and by the thorax being narrowed from the
