Laredo to Ringgold Barracks. Mr. Schott. The arrangement of Buprestidae 

 is at present in such confusion, that I am unable, by the books, to determine the 

 proper reference of this species. Generic characters of much importance in this 

 family have been lost sight of in the arrangements proposed, and a thorough re- 

 vision is necessary. This particular species has for generic characters : clypeus 

 broadly but regularly emarginate ; the antennae inserted under a strongly elevated 

 line which runs obliquely towards the emargination of the clypeus ; the labrum 

 emarginate; the mentum rounded anteriorly; the scutel small, transverse and 

 rounded : coxal plates much but gradually dilated internally : rnesosternum di- 

 vided, with the portions entirely connate with the metasternum : palpi almost 

 cylindrical, with subequal joints : anus very slightly emarginate : tarsi with the 

 joints 1 4 broadly lobed, the lobe of the fourth joint rounded : the basal joint of 

 the posterior tarsi very little longer than the second: the mandible are thick, 

 short and obtuse. 



Buprestis a m b i e n s, laete viridis, aenescens, elongatus minus convexus, capite 

 valde rujjosoet punctato, oculis mediocribus, thorace latitudine breviore punctato 

 lateribus rotundatis, flavo-marginatis, basi fere recte truncata, fovea ad medium 

 alteraque utrinque ad angulos notata, elytris basi coniunctim subemarginatis, hu- 

 meris acutis, lateribus flavo-marginatis, parallelis a dodrante angustatis, apice 

 truncatis, sat profunde striato-punctatis, interstitiis paulo convexis, parce punc- 

 tulatis. Long. *68. 



Frontera (Rio Grande), Mr. Clarke. Although having very much the form of 

 Anthaxia, this species differs considerably in its generic characters ; the an- 

 tennre palpi and feet are unfortunately wanting, but the following marks will 

 enable the genus to be recognized : 



The antennae are near the eyes, (which are moderate in size) and are inserted 

 on the front : behind the insertion is a deep fovea, at the bottom of which is a 

 round shining tubercle* (as in Dicerca) ; the clypeus is very broadly emarginate 

 in the arc of a circle, (labrum wanting) ; the mandibles are short, thick and ob- 

 liquely truncate; the mentum is broaci and rounded anteriorly; the rnesosternum 

 firmly connate with the metasternum; the posterior coxal plates with the poste- 

 rior outline concave so as to form an internal tooth; anus not emarginate ; scutel 

 very small, subtriangular. 



The yellow margin of the thorax is posteriorly separated from the disc by an 

 impressed line : the yellow of the elytra is slightly dilated behind the humerus 

 nd again about the middle. 



Phaenops m i r a nd u s, niger, aenescens subtiliter dense punctulatus, capite 

 guttis 5 politis, circulo positis, thorace guttis 4 anticis (intermediis maioribus) 

 alteraque utrinque pone medium, lineaque dorsali postica nitidis Icevigatis ; ely- 

 tris margine basique tenuiter rubris, lineiscue fiavis decussatis oinatis.

Fort Union, New Mexico, Major Sibley. This beautiful species is nearly of 

 the same form as our common black P. longipes, but is less acute posterior- 

 ly : the yellow lines of the elytra are arranged so as to include the following 

 spots : a large common triangular one at the scutel, separated from the base by 

 the red margin ; an elongated lateral spot extending from behind the humerus to 

 two-fifths the length: a large common rhomboidal spot on the suture, extending 

 from the second to the fourth fifth of the length : immediately opposite the ex- 

 ternal angle of the rhomboid, a small submarginal black dot , finally a large api- 

 cal blotch ; separated from the rhomboid by a narrow yellow line, and from the 

 margin by the red marginal line above mentioned. The yellow stripes which 

 bound the anterior faces of the rhomboid are considerably broader than the 



*Is this an ocellus, or a tympanum ?
