mucronate and broadly rounded. The male has the last ventral 

 segment transvex'selj excavated posteriorly. All the ventral 

 segments in both sexes are punctured, and there are traces of 

 whitish spots on the middle and sides of each.

 This species closely resembles T. cosiaius, Mastersii, and 

 impressicollis, but may be readily distinguished from the whole 

 of them by the short, distinct, very oblique ridges near the base 

 of the rostrum, and the strongly mucronate elytra. The sexes 

 scarcely differ. 



Talaurinus mdrtcatus. 



Oblongo-ellipticus niger confertim cinei'eo-squamosus albo- 



vittatus, rostro lato bicarinato carinis subparallelis, thorace 



tuberculato tuberculis parvus dorso sublasvi lateribus medio 



ampliato, elytris albo-squamosis seriatim punctatis granulatis 



bifariam tuberculatis tuberculis nitidis validis conicis.

This insect approaches T. incanescens. The head and rostrum 



are broad, short, and flat, the ridges of the latter being almost 



parallel. The thorax is rather thickly covered with small 



hemispherical tubercles, excepting in the middle where there is 



a broadish space without any. The elytra are punctured and 



granulated in regular series, and have also on each two rows 



of large, sharp, glossy tubercles, numbering about seven in 



the inner, and eight in the outer row. In the specimen before 



me there are besides two tubercles on one elytron, and one on 



the other between the inner row and the suture. All the granules
