vated in the middle, are likewise black, with irre- 

 gular bands formed of yellow confluent spots ; two 

 of these spots, one on the shoulder of each elytron, 

 and another at the apex, are reddish ; the surface is 

 marked w r ith dark impressed points, which form ir- 

 regular lines anteriorly. The under side and legs 

 are black. The markings vary much, in some in- 

 stances the black bands on the elytra being almost 

 obliterated. 



SPHENISCUS EROTYLOIDES, 



PLATE XXIX. Fig. 6. 

 Kirby, Linn. Trans, xii. pi. 22, fig. 4. 



This genus was established by Mr Kirby on an 

 insect from Brazil, very closely related to Helops. 

 The head and thorax are black and shining, the latter 

 sparingly punctured. The elytra are very gibbous 

 in the centre, marked w r ith punctured lines, of a 

 pale-yellow colour spotted with black, and having a 

 broad band over the middle, and the apex black. 

 The under side and legs are likewise black. The 

 figure of this insect has been accidentally placed 

 among the tetramerous insects, but it belongs to the 

 heteromerous section, as will be seen from the num- 

 ber of joints in the tarsi.
