B.—e. 
12. D. asperata, cinereo-zenea, fronte late concava, carina transversa inter antennas signata, thorace latitudine 
sesqui breviore, lateribus antice rotundatis, postice parallelis, rade punctato, ineequali, vittis quatuor (externis an- 
gustis) nitidis leevibus, sulco dorsali plaga levi interrupto, parte postica profundiore, elytris dense punctatis, striis 
punctis fortioribus notatis, interstitiis plagis paucis oblongis nigris notatis, postice oblique angustatis, vix prolongatis, 
bidentatis. Long. -62—70.

2Buprestis americana Herbst, Kafer, 9, 107, tab. 148, fig. 3. 
Middle and Southern States, rare. The tip of the abdomen of the male is truncate 
and emarginate, and the middle tibie are armed internally with a large tooth. The fe- 
male has the tip of the abdomen tridentate, and the middle tooth rounded at tip. 
This species was first well described by Dr. Melsheimer; Laporte and Gory’s figure and 
description are as usual very poor. The description by Herbst is somewhat indefinite, 
and it is difficult to know whether it should refer to this or to D. chrysea of the division C. 
Tn addition to the characters given in the diagnosis I may mention that the head is 
transversely elevated between the eyes; the occiput has two smooth elevations; the ex- 
ternal smooth vittee of the thorax are narrow, but entire, the dorsal channel is punctured, 
and is interrupted by an elongate smooth elevation, behind which it is deeper than in 
front. The pectoral groove is very deep in the male, shallow in the female, and the an- 
tepectus is hairy in both sexes.

13. D. tenebrosa, cinereo-enea, vel obscure venea, thorace latitudine plus duplo latiore, lateribus dilatatis, 
antice rotundatis postice sinuatis, rude punctato, postice utrinque late excavato, callis utrinque apicalibus et basali- 
bus levibus nitidis, sulco dorsali profundo costis levibus definito, medio subinterrupto, elytris dense punctatis, 
interstitiis alternis spatiis oblongis elevatis nitidis variegatis, ad apicem prolongatis integris. Long. -57—-75. 
Mas pectore late sulcato villoso, tibiis intermediis dente interno acuto armatis, sezmento ventrali ultimo truncato- 
emarginato. 
Femina pectore subglabro minus sulcato, segmento ventrali ultimo tridentato, dente intermedio obtuso, incisuris 
minutis definito. i 
Buprestis (Stenuris) tenebrosa Kirby, Fauna Bor. Am. 195. 
Abundant at Lake Superior; according to Kirby found in Lat. 65° and in the Rocky 
Mountains. The suture in this and in all the following species is elevated. In addition to 
the characters given in the diagnosis, it may be mentioned that the under surface is copper 
coloured, coarsely and densely punctured on the sides, abdomen and prosternum, less 
densely on the metasternum and middle of the first segment of the abdomen: the divided 
portions of the mesosternum are coarsely, and tolerably densely punctured. The outer 
costz of the thorax are interrupted so as to form on each side an apical and basal cal-
