tarsi a little incrassate, the apical ventral seement is truncate, but distinctly 
produced in the middle and thus slightly sinuate on each side. In the female the 
epipleuree are simple, and the last ventral segment has a much produced middle 
lobe, and the portion on each side of this is nearly truncate.

This species is as long as L. luridus, but is quite different in form being very 
much broader in front and comparatively little convex. The base of the thorax in 
the middle is very little acuminate ; the hind tarsi are very broad. The male 
tarsi are not much incrassate, but their clothing beneath is more largely developed 
than usual, the palettes of the under surface being quite conspicuous, and placed on 
clongate hairs, and form four transverse series; the apical ventral segment is 
much abbreviate, the hind margin rather deeply sinuate on each side, and very 
broadly rounded in the middle, The female I have not seen.

139. Laccophilus luridus, Schaum, M.C.—Late ovalis, apice latius rotundatus, sat 
nitidus, testaceus, elytris vix obscurioribus, immaculatis. Long. 54, lat. 3} m.m. 
The male has the front and middle tarsi a good deal incrassate ; the apical ventral 
segment is truncate, but a little produced in the middle and sinuate on each side ; 
in the female the central lobe of this segment is elongate, and its hind margin is 
very slightly reflexed. The broad form, large size, and almost completely immacu- 
late elytra, make this species distinguishable! at a glance.

i have seen but a single female of this very distinct species, the sculpture of it 
resembles that of Laccophilus undatus, (No. 123) the prosternal process is however 
elongate in the present species : the apical ventral segment is truncate and but little 
produced in the middle.

the locality of this species is correct. 595.
