dorso ante medium conspicue condensatis, spatio obscura ita 

 formata retrorsum triangulariter in medio producto et postea 

 a squamis pallida cinereis valde distincto ; funiculi sat 

 robusti articulo 1° quam 2"^ duplo longiori, ceteris brevibus, 

 ultimis transversis ; clava bi-evi lata.

 ?hujus speciei maris rostro quam prothorax manifeste 

 longiori, gracili, leviter arcuato ; anteunis paullo ante rostri 

 medium insertis. Femin^ rostro quam prothorax manifeste 

 longiori, gracili, leviter arcuato ; antenuis parum ante rostri 

 medium insertis. 

 I am not quite sure of the specific identity of the two speci- 

 mens before me, owing to their sexual differences being very slight 

 as compared with those of other species of Emplesis, and yet 

 sufficient to forbid their being regarded as both of one sex of the 

 same species, — their rostra scarcely differing inter se except in the 

 antennae being inserted in one very little, and in the other much, 

 in front of the middle. Their agreement in somewhat peculiar 

 markings and in an unusually short robust antennal club, how- 

 ever, is strongly opposed to the idea of their representing two 

 species. Their general characters are exceedingly close to those 

 of B. notafa, &c., but they are very differently marked. Regarding 

 the ferruginous scales as forming the groundwork of the pattern, 

 the dark scales are arranged on the prothorax much as in U. 

 notata, but on the elytra they occupy nearly the whole of the 

 anterior half, becoming more definedly dark hindward till the 

 hind-edge of this darker portion is not far short of being black, 

 and is triangularly produced hindward about the suture to some- 

 what behind the middle, where it is in strong contrast to the 

 paler scales which are at their palest immediately behind it. 

 There are also some dark patches variegating the apical portion. 

 S. Australia ; near Adelaide. 



The following tabulation will assist the identification of the 

 described species of this genus.

 in front of the anterior coxee.
