314 On Aquatic Carnivorous Coleoptera or Dytiscide. 
This is the smallest species of the genus. The elytra are dark without trace of 
‘yroration or flexuous lines, and show a band near the base, and another a little 
beyond the middle yellowish, this latter being pretty widely interrupted at the 
suture, the apex is also pale, and there is a small pale spot on the lateral margin 
between the two fasciz. 
I do not know the male; and of the female I have seen but one individual (which 
has lost its head), this has the last ventral segment truncate, and with a very slight 
projection in the middle of the hind margin ; on each side of this it is distinctly 
oblique, but there is no sinuation. Though the species has some resemblance of 
colour to L. quadrimaculatus, it is much smaller, and the apical ventral segment 
in the female is of a different shape.

167. Laccophilus cingulatus, n. sp.—Ovalis, subdepressus, sat latus, pernitidus, 
testaceus, prothorace anterius et posterius in medio, abdomine pectoreque infus- 
catis; elytris fuscis, fascia sub-basali fere integra pallida, colore fusco lineis valde 
flexuosis angustissimis diviso. Long. 34, lat. 14 m.m. 
The dark marks of the elytra in this species are so extended as to make the 
elytra appear entirely dark, the irregular pale marks which separate the dark lines 
being very reduced; on the other hand the pale fascia near the base is remarkably 
definite and conspicuous. The male has the front and middle tarsi but little incrassate, 
the apical ventral segment is a little produced in the middle so as to be oblique, but 
not sinuate on each side.

168. Laccophilus basalis, Motsch. M. C.—Ovalis, subdepressus, pernitidus, testa- 
ceus, elytris fusco-suffusis, colore fusco lineis valde flexuosis diviso, et ante apicem 
plus minusve interrupto et desinente, fascia sub-basali fere integra pallida. 
Long 3, lat. 1s m.m. 
This species bears a great resemblance to L. cingulatus, but the thorax is 
without dark marks, and the underside is pale, and the dark marks of the elytra 
are not so entire on the apical portion, for besides the very conspicuous pale band 
near the base, there is an interruption of the dark colour before the apex so as to 
form a very broken pale band, and the dark colour does not extend quite to the 
apex. The male has the front and middle tarsi but little incrassate, and the 
apical ventral segment is a little produced in the middle so as to be oblique but 
not sinuate on each side; the female appears to me to have the apical segment 
entire, and simply curved at the sides so as to be without sinuation, but the only 
individual I have seen of this sex is in such bad condition that I cannot speak
