pone medium exaratis, interstitiis uniseriatim subtilius punctatis. Long. 

 10 mm. 



One specimen, Arizona, Dr. Coues. This species resembles A. variegata 

 in the marking of the elytra, and general form of the body, but differs 

 essentially in the form and excavations of the thorax ; the sides are consider- 

 ably rounded, less oblique than in A. c o n n e x a, less suddenly and less 

 strongly incurved at the hind angles ; the transverse submarginal crest of the 

 last ventral segment is very short, almost as in A. o rna ta. 



AGRILUS Sol. 



A. Couesii, viridisenens, capite nitido, fortiter punctato, fronte bitu- 

 berculato, vertice transversiin valde excavato, thorace obscuro, rugose punc- 

 tato, costis elevatis duabus politis, snlco dorsali maximo lateribusque oblique 

 excavatis, his albo pubescentibus. lateribus fere rectis angulis posticis cari- 

 natis ; elytris confertim punctatis, sutura costaque utrinque dorsali fere ad 

 apicem extensa, elevatis laevibus obscuris, suleo subsuturali breviter cinereo- 

 pubescente, spatiis duabus laevibus nitidis versus apicem ornato, apice parce 

 spinosis ; subtus maculis argenteo-pubescentibus variegatus. Long. 11 mm. 



One specimen, Arizona. It gives me pleasure to commemorate the valued 

 labors of Dr. Coues in Arizona by dedicating to him this beautiful species. It 

 is of a more tropical form than any other in my collection, and is easily recog- 

 nized by the characters given above ; the two spots in ths elytral sulcus unite 

 the elevated suture and the discoidal costa ; one is at the end of the latter, and 

 the other a little anterior. The scutellum is of the usual form, but is deeply 

 excavated and punctured in the middle, and not transversely carinate ; the 

 ungues are armed with a large tooth, which is not acute at tip. This species 

 is to be placed as a distinct group, before A. bilineatus. (Vide Lee. Trans. 

 Am. Phil. Soc. xi. 242.) 



A. c unens, linearis, postice angustior, aeneus, opacus, capite convexo, 

 confertim punctato, vix canaliculato, thorace latitudine baud breviore, lateri- 

 bus fere rectis, postice paulo angustato, angulis posticis longe carinatis, disco 

 confertim punctato et transversim rugoso, medio obtuse canaliculato, lateri- 

 bus anguste depressis ; elytris versus suturam longitudinaliter impressis, ab 

 humeris sensim angustatis, apice serratis et singulatim rotundatis, confertim 

 sequaliter granulatis : subtus aeneus nitidus, subtiliter punctatus, abdomine 

 antice late canaliculato. Long. 5 ram. 



Texas ; one specimen in the collection of Mr. Ulke. This species belongs 

 to the division having the claws distant, and armed with a broad, not very 

 prominent tooth. 



XENORHIPIS Lee. (n. g. Buprestidse.) 



X. Brendeli, aeneoater, opacus, capite thoraceque reticulatim punctatis, 

 hoc quadrato, subtilius canaliculato, ante medium transversim irapresso, ely- 

 tris granulis elevatis asperatis, margine praecipue postice serrulatis, plaga ba- 

 sali pallida ornatis. Long. 5 mm. 



One specimen, Peoiia, Illinois; collected by Dr. E. Brendel and communi- 

 cated to me by Mr. H Ulke. 



This new genus has the general form and sculpture of Anthaxia, but differs 

 from that as from all other Buprestidse by the antennae being pec'inate. 



Body elongate, dull black, with a brassy tinge ; head and thorax sculptured 

 with shallow reticulations (as in Anthaxia); the former convex, with a broad 

 medial furrow; antennae longer than head and thorax, black, 11-jointed, first 

 joint obconical, second and following about equal in length, produced exter- 

 nally into a long process, which is near the base in the second joint, but gra- 

 dually changes its position until it becomes apical in the tenth joint ; eleventh 

 joint similar in length and form to the ramus of the tenth joint. Thorax 

 quadrate, wider than its length, with the angles acute ; slightly convex,
