172. Laccophilus cognatus, n. sp.—Ovalis, parum convexus, nitidus, testaceo- 
rufus, elytris lineis flexuosis fuscis integris, sed valde irregularibus. Long. 4, lat. 
2¢ m.m. 2 
This species is similar in colour to L. solutus, but is different in form, the head 
being narrower; the marks on the elytra are very distinct, excessively irregular, 
and cover the whole surface except the lateral margin. The male has the front 
and middle tarsi moderately incrassate ; the apical ventral segment is much sinuate 
on each side at the hind margin so that the middle forms a prominent lobe: the 
female I have not seen.

173. Laccophilus religatus, n. sp.—Ovalis, subdepressus, nitidus, testaceo-rufus, 
elytris lincis sat latis, undulatis, fere integris, fuscis. Long. 4, lat. 2¢ m.m. 
The lines on the elytra in this species are distinguishable as distin ct waved lines, 
or rather as moderately thick lines with waved edges, these undulations of the 
margins being in some places so great as almost to form connections between the 
different lines. The male has the front and middle tarsi a good deal incrassate : 
it has the last ventral segment truncate, and not produced in the middle ; in the 
only specimen I have seen there is a rather deep emargination or notch on the 
right side of the hind margin, but there is only very little trace of such a notch on 
the left side.

i74. Laccophilus addendus, n. sp.—Ovalis, minus convexus, nitidus, testaceus, 
prothorace anterius et posterius in medio sub-infuscato, elytris fusco-irroratis, 
irrorationibus ad basin inzequaliter desinentibus. Long. 4, lat. 24 m.m. 
The marks on the elytra are in this species so broken up as to have the 
appearance of irrorations, some of these irrorations extend in an uregular linear 
manner to the base, while others of them are abbreviated, there is thus formed an 
indefinite, broken pale fascia at the base. In the female the hind margin of the 
apical ventral segment forms in the middle a broad, short, rounded lobe, and is 
sinuate on each side so that the lateral angles are distinctly prominent. 
In M. de Bonvouloir’s collection is a larger male individual, with the irrorations 
of the elytra smaller and more numerous, which may perhaps be a variety of this 
species, it has the front and middle tarsi much incrassate: and the hind margin of 
the apical ventral segment is a good deal prolonged in the middle and sinuate on 
each side.
