308 On Aquatic Carnivorous Coleoptera or Dytiscide. 
elytra are suffused leaves, besides the fascia near the base, some small obscure 
variable marks behind the middle pale, and the dark colour scarcely reaches the 
epipleure. The male has the front and middle tarsi but little incrassate; and has 
the apical ventral segment subtruncate, with a slight acuminate projection in the 
middle; in the female this projection is more acute and longer, and the hind 
margin is rather oblique on each side, and close to the side is rather deeply sinuate. 
I have seen but one pair of the species, in rather bad condition.

In this species the lines of the elytra are straight lines with irregular edges, and 
are not interrupted so as to give rise to any appearance of transverse pale bands ; 
the lines towards the sides are, however, more or less broken up into irregular 
irrorations. The yellow interstices are irregular being greatly broken up by the 
black marks especially near the extremity. In the male the front and muddle tarsi 
are distinctly incrassate; and the apical ventral segment is truncate, and but 
slightly sinuate on each side; in the female it is deeply sinuate on each side, so 
that the middle part forms a very broad lobe. The species seems to be very 
variable in the dark lines of the elytra which are sometimes very black and 
approximate, though always distinctly separated, while in other cases they are so 
diluted as to appear merely lines of irrorations.

151. Laccophilus complicatus, n. sp.—Ovalis, sat latus et convexus, nitidus, 
testaceus, elytris lineis undulatis, haud interruptisnigris. Long. 45, lat. vix 23 m.m. 
In this species there is a small infuscation of the anterior and posterior margins 
of the thorax in the middle ; the lines of the elytra are very waved, and are evenly 
distributed, those near the suture not approaching in their character to straight 
lines; by this it is easily distinguished from the closely allied Laccophilus cyclopis, 
the ventral segments are more or less infuscate. In the male the front and middle 
tarsi are much incrassate, and the apical ventral segment is truncate but the 
middle part is evidently produced, so that the hind margin is distinctly oblique 
on each side ; in the female the middle part is more produced so that it forms a 
broad short lobe.
