narrowed in/front and behind ; the reticulation of the elytra is even more indistinct, 
but there are some very fine punctures visible, especially near the suture towards 
the extremity : the infuscation and variegation of the elytra is excessively reduced, 
and is only to be perceived by expanding them. Notwithstanding its near approach 
to Dysticus obscurus, (No. 130), I feel pretty sure that this is a distinct species.

132. Laceophilus kobensis, Sharp, Tr. Ent. Soc. Lond. 1873, p. 53.—Ovalis, 
minus elongatus, sat convexus, nitidus, testaceus, antennis palpisque apicibus 
angustissime infuscatis, elytris sat distincte fusco-variegatis; prothorace basi in medio 
minus breviter producto. Long. 34, lat. 24 m.m. 
The male has the front and middle tarsi much incrassate. The species is 
extremely closely allied to the two preceding, but the smaller size and shorter form 
make it easy to be distinguished from them.

33. Laccophilus sordidus, n. sp.—Ovalis, convexus, sordide testaceus, fere 
unicolor, antennis testaceis ; prothorace basi in medio elongato, acuto ; elytris sub- 
tiliter sed evidenter reticulatis, stria suturali punctorum. Long. 5, lat. vix. 3 m.m. 
The male has the front and middle tarsi distinctly a little incrassate ; the last 
ventral segment is simple and entire in each sex, slightly longer in the male than 
in the female. 
The two individuals before me are in bad condition, and perhaps darker in colour 
than is natural; there is no trace of any markings, and the species should be 
readily identified by its moderately large size and obscure colour, by the simple 
structure of the last segment in each sex, the very acutely angled base of the thorax, 
and by the reticulation of the elytra, and the obscure series of impressed punctures 
along the suture.

The yellow marks on the wing cases are in this species large and definite, there 
is a large irregular transverse yellow band very close to the base, a yellow spot 
on the lateral margin about the middle, another large irregular transverse band in 
front of the apex, and the apex itself is also pale. The species bears much 
resemblance to Laccophilus bifasciatus (No. 111), from the Antilles ; itis remarkable
