136 REVISION OP THE GENUS LAMPRIMA OP LATREILLE, 



projecting downwards on each side of the labrum. The palpi are 

 normal. The maxillje and labium are enveloped in yellow haii', 

 but do not appear to be at all corneous. The raentam is of a 

 metallic green, strongly punctate, and of a transverse triangular 

 form. The thorax is quadrangular, a little broader than the 

 length, a little narrower at the apex than at the base, bisinuate on 

 both, a rounded angular dilatation with a depression on the sides 

 behind the middle, the entire lateral margin crenulated with 

 about fifteen short, strong, blunt teeth, and a number of small 

 dense punctures in the median line. The colour of the thorax is 

 of a deader metallic hue than the rest of the body. The scutellura 

 is of a rounded triangular form, with a few small punctures. The 

 elytra are more than twice the length of the thorax, about the 

 width, at the base, of the thorax and narrowing a little to the apex ; 

 the colour is very brilliant, the greenish-gold of the sides changing 

 into a coppery hue in the middle. Each elytron has a very distinct 

 sub-apical callus, and is marked by a number of large shallow 

 variolose punctures, disposed thinly in irregular I'ows, with densely 

 punctate recurved margins. The under surface is of the same 

 colour and. brilliancy as the upper. The prosternum shows in a 

 narrow keel between the fore legs, the mesosternum is shortly 

 pointed and concave on its anterior face ; these with the metas- 

 ternum and sides of the abdominal segments are clothed with a 

 yellowish pubescence. The thighs are of the colour of the body, 

 and of moderate size ; the tibiae and tarsi are black or piceous- 

 black ; the fore tibise are broad and armed externally with seven 

 teeth ; the other tibiae have two teeth near the middle on the outer 

 side ; the tarsi are rather shorter than the tibiae. 



Length, 17 lines.

This large and beautiful species might well form the type of a 

 new genus ; the triangular mentum, strongly crenulated thorax ; 

 and entirely peculiar puncturation of the ely tx'a, seem to constitute 

 almost generic characters. But in the absence of a male s]iecimen, 

 which may probably prove to be still more peculiar, it would be 

 premature to attempt to make a genus for its reception.
