near their outer extremity ; their tarsi have the hind margins of 

 the joints externally slightly lobed beneath, and are terminated by 

 two claws. The elongated palpi, when viewed in one direction, 

 show an evident emargination at their slightly truncate extremity. 



Three species are from Chili, one from Buenos Ayres, and one 

 from Australia and New Zealand. 



2341. L. lanceolatus. (Sharp; Aquatic Coleop., p. 602.) 

 Ovalis elpngatus, aurantiaco-testaceus, vertice late, prothorace 

 anterius et posterius in inedio, elytris vittis elongatis nigris ; elytris 

 subtiliter undulatim strigosulis, punctis seriatis conspicuis, apice 

 subtruncatis ; prosterno in medio anterius sub-prominulo, vix rotun- 

 dato. 



Long., lOfrnni. ; lat., 5mm. 



The male has the basal joints of the front tarsi a good deal 

 dilated and moderately compressed, and furnished beneath with 

 rather long hairs and rows of distinct palettes ; their claws are 

 rather long and unequal, the anterior one being very slender, while 

 the posterior is stouter and thickened from the apex to the base, and 

 near the base has a sharp projecting tooth ; the middle tarsi are 

 incrassate and strongly compressed, and furnished beneath with 

 long hairs and palettes. The apical ventral segment in this sex is 

 deeply strigose 011 its apical portion, while in the female these 

 striae are quite obsolete. There is also a very slight sexual difference 

 in the sculpture of the elytra, the female being slightly less shining, 

 and having the sculpture near the shoulders forming more or less 

 distinct, obliquely transverse, elongated scratches.

Rygmodus (Gen., p. 79). 



2342. R. limbatus, n.s. Oblong -oval, shining, head and 

 thorax nearly black, the sides of the latter broadly rufescent ; 

 elytra nigro-cyaneous, with red margins ; tibiae red, femora slightly 

 paler. 



This species is most nearly allied to E. femoratus. The thorax 

 is nearly twice as broad as it is long, very gradually narrowed 

 towards the point, the sides are broadly explanate, and the punctua- 

 tion is more distinct than it is in B. femoratus. The elytra are like 

 those of that species, rather broad, with rather deep and distinctly 

 punctured striae; the margins, however, are quite red; the interstices 

 have fine numerous punctures. There is no well-marked contrast in 

 coloration between the femora and tibiae. The front margin of the 

 head is only indistinctly raised. 



Length, 3-| ; breadth, If lines.

 J?. modestus which were sent by Mr. A. T. Cavell.
