rounded ; eyes with their inner margins oblique as usual; tarsi longer; 

 body not cuneiform 1 1 



Hind coxae but slightly dilated within, their posterior edge thence transverse 

 to the sides of the body; eyes parallel within; antero-terminal fossae 

 of the outer antennal joints large and irregular, the joints also with a 

 small lateral fossa in addition; body subcuneate in form 13 



II — Pronotum more closely punctate or depressed along the median line; 

 elytra roughly sculptured, more or less prolonged at tip, not or scarcely 

 serrate at the sides posteriorly; antennae inserted in larger depressions 

 under more or less pronounced oblique elevations of the front. Hol- 

 arctic regions. [Type Buprestis cenea Linn.] Dicerca 



Pronotum subelevated and impunctate along the median line; elytra less 

 roughly sculptured and usually with more distinct striation 12 



1 2 — Antennae inserted under oblique prominences somewhat as in Dicerca; 

 elytra more or less feebly produced at tip, not or scarcely serrulate at 

 the sides, the apices truncate or sinuate and generally bispinulose; 

 surface with sombre coloration. Holarctic regions. [Type Buprestis 

 variolosa Payk.] Poecilonota 



Antennae inserted in exposed foramina, the supra-antennal ridges obsolete; 

 elytra not produced at tip, feebly serrulate at the sides posteriorly, the 

 apices more or less truncate and multispiculose; integuments with vivid 

 metallic coloration. Europe. [Type Buprestis festivalArm.]. *Lampra 



13 — Antennae inserted in small frontal foramina, very short and compact; 

 pronotum feebly impressed medially toward base, otherwise almost 

 evenly convex ; scutellum small; elytra subevenly cribrate and with very 

 faint subconvex smoother lines, the sides serrate posteriorly and at the 

 narrowly rounded apex, which is not at all produced; tarsi very short. 

 Sonoran regions. [Type Halecia gentilis Horn] Anataxis 



14 — Scutellum small as usual but distinct and normal 15 



Scutellum obsolete; elytra without striation 16 



15 — Antennae inserted in small foramina under very small, feeble and 

 inconspicuous ridges, short, compact, the joints nearly as in Dicerca 

 but more convex and with dense sensitive pores beneath, the sensory 

 fossae intero-terminal, distinct and circular, the last joint with a strong 

 terminal process as in Gyascutus; body small, subcylindric, the eyes 

 widely separated, with their inner margins but slightly converging up 

 ward; prothorax subparallel and broadly rounded at the sides, faintly 

 impressed along a part of the median line; legs slender; tarsi short; 

 hind coxae dilated internally as usual; first ventral suture distinct, 

 rectilinear throughout; elytra feebly serrulate at the sides and finely 



striato-punctate. California. [Type N. cupreofusca n. sp.] 



Nanularia 



Antennae inserted in very small and widely separated foramina, which have 

 their upper edges horizontally acute but not ridged, very slender, the 

 outer joints elongate and much as in Buprestis, sparsely punctate, 

 more closely and subrugulosely beneath, with very small rounded intero-
