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. Laccophilus Uobensis, 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. 31, lat. 2i 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 seo-ment 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 

 alonof the suture.

134. Laccophilus elegans, n. sp. — Ovalis, parum elongatus, subdepressus, 

 nitidissimus, testaceus, elytris nigricantibus, signaturis magnis testaceis. Long. 4, 



lat. 2^ m.m. 



The yellow marks on the wing cases are in this species large and definite, there 

 is a laro-e 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. Ill), from the Antilles ; it is remarkable
