172. Laccophilus cognatus, n. sp. — Ovalis, parum convexus, nitidus, testaceo- 

 rufus, elytris lineis flexuosis fuscis integris, sed valde irregularibus. Long. 4, lat. 

 2i m.m. 



This species is similar iii colour to L. solutus, but is difterent 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-rutus, 

 elytris lineis sat latis, undulatis, fere integris, fuscis. Lorg. 4, lat. 2i m.m. 



The lines on the elytra in this species are distinguishable as distinct waved lines, 

 or rather as moderMtely thick lines with waved edges, these undulations ot 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 1 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.

174. Laccophilus addendus, n. sp. — Ovalis, minus convexus, nitidus, testaceus, 

 prothorace anterius et posterius in medio sub-infuscato, elytris fusco-irroratis, 

 irrorationibus ad basin insequaliter desinentil)us. 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 irregular 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 mai'gin 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 Bouvouloir's collection is a larger male individual, with the irrorations 

 of the elytra smaller and move 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.
