About the size of X. tcrminatum, but of totally different 

 colour, and with the head larger and differently shaped. 

 Antenniu yellow, about as long as head and thorax, 

 formed much as in L. tenninatum, but slightly stouter, 

 the penultimate joints a little shorter ; 3rd joint distinctly 

 longer than 2nd. Head about as broad as the thorax, the 

 hinder angles not rounded, the front part sparingly and 

 rather coarsely punctured ; the disc shining and impunc- 

 tate ; the hind angles densely and finely pimctiu-ed. 

 Thorax subquadrate, straight at the sides, quite as long 

 as broad, a little narrower than the elytra ; a broad line 

 along the middle impunctate ; the sides moderately 

 coarsely and not closely punctured ; the medial ])unctures 

 at the hind part separated from the others by a nan-ow, 

 smooth space. Elyti-a rather longer than the thorax, 

 finely and not closely punctured, the punctures indistinctly 

 an'anged in lines. Hind body with the basal segments 

 ])itchy, the hind part reddish-yellow, A'ery finely punctured. 

 Legs yellow. 



In the male the 6th segment of the hind bodj beneath 

 has a longitudinal impression along the middle ; its hind 

 margin is broadly but very shallowly emarginate, the 

 emargination limited on each side by a slight projection ; 

 the 7th segment has a rather broad and deep notch, the 

 front part of which is rounded, and not notched. 



Tapajos ; one specimen, <? . 



9. Latlirohium proximum, n. sp. Rufo-testaceum, niti- 

 dulum, parallelum, abdomine piceo, apice rufo-testaceo ; 

 capite angulis posterioribus dense subtilitcr punctatis, 

 disco \vQ\'\ ; prothorace lateribus crcbre punctato, linea lata 

 impunctata. Long. coip. 3 lin. 



ISIas : abdomine segmento 7° ventrali apice sat pro- 

 funde exciso ; segmento 6° late impresso (impressionis 

 apice impunctato), margine posteriore leviter emarginato. 



Extremely close to X. rvfulum, and differing only as 

 follows : the antenna? are rather longer, the 3rd joint 

 considerably longer than the 2nd, the thorax is more 

 closely punctured : and in the male the 6th segment of 

 the hind body beneath has a broader, ill-defined impres- 

 sion, at the extremity of Avhich is a triangular impunctate
