from them for the purposes of elassifieation. He divides the 
insects forming tliis group into two groups (families) denomi- 
nated Buprestes and Elateres, the MelaMcs and Eucnemidce of 
authors being included in the latter. 
The characters given for these two primary groups are as 
follows : — 
I. Buprestes. Epimera mesothoracica inter episterna et humeros ely- 
trorum ad epimera prothoracis ascendentia et cum iis articulata. Prosternum 
mucrone saltatorio nullo^, mesosterno receptum. Segmenta ventralia duo 
priora concreta. Procursus ventrales laterales epimera metathoracica attin- 
gentes, spiracula metathoracica in segmento mediali sita extrorsum cingentes ; 
procursus ventralis medius inter coxas posticas ad mesosternum usque pro- 
cedens. Mandibulm tetragonsey crassse, cochleariformes. Alee in longitu- 
dinem plicatee. Pedes ambulatorii, trochanteribus posticis simplicibus, tarsis 
pulvillatis. Oculi oblongi. 
Tracheae vesiculosin. Glandulee salivates in capite sitee, filiformes, fasci- 
culato-ramosee. Ventricuhis chylificus bicornis, parte postica in spiram con- 
voluta. Vasa malpighiana terna, apice intestine affixa. Eolliculi testicu- 
lorum scroto inclusi, gracillimi, longissimi, apice cpnjunctim in spiram con- 
torti j vesiculee seminales binee. Receptaculum seminis feminee simplex^ 
glandula appendiculari nulla. Systoma nervorum : ganglion mesothoracis 
cum ganglio metathoracis concretumj ganglia abdominalia quinque, duo 
priora in thorace sita; ganglion abdominale primum a ganglio metathoracico 
discretum. — W ood-boring. 
II. Elateres. Epimera mesothoracica epimera prothoracis non at- 
tingontia, articulo cum prothorace non conjuncta. Prosternum aut supra 
sub apicem mucrone arniatum saltatorio, aut in mucronem saltatorium sen- 
sim transiens. Mesosternum fovea profunda mucronem excipiens. Procursus 
ventrales epimera metathoracica non attingentes ; spiracula metathoracica ex-» 
trorsum libera, inter epimera et procursus ventrales sita ; procursus ventralis 
medius brevis, ad metasternum vix procedens. Mandibulae triquetrse, formi- 
cate, apicem versus extenitate. Ale in longitudinem et transverse plicate. 
Pedes cursorii, trochanteribus posticis fulcientibus. Oculi rotundati. 
Trachee vesiciilis carentes. Glandule salivales proprie nulle. Ventri- 
culus chylificus simplex, subrectus. Vasa malpighiana bina, apice libera. 
Eolliculi testiculorum scroto carentes, oblongi vel globosi; vesicule semi- 
nales 'terne, structura maxime varmntes. Receptaculum seminis femine 
structura valde varians, sepissime duplex aut multiplex, glandula appendi- 
culari magna, sepissime ramosa. Systema nervosum : ganglia thoracica 
discreta ; ganglia abdominalia octo, duo priora in thorace sita ; ganglion ab- 
dominale primum ganglio metathoracis applicatuni. — Normally carnivorous. 
The Bupvestes include the tribes Antliaxiim (genera Chry- 
sohothris, Metanophilaj and Anthaxid), Bupr^stini {Buprestis, 
Chalcophoraj and Ancylochira) , and Agrilini (Agrilus, Trachys, 
and Aphanisticus ) . 
The Elateres are divided into two sections, of which the first, 
including the tribes Melasini {Melam and Xylobius) and Eu- 
cnemidini [Eucnemis, Microrhagus^ and Throscus), approaches 
the Buprestes in some characters, such as the absence of fimbrise
