[Long. 3-|-4, lat. 1-i lines. 

 The subdiaphanous lateral margins of the prothorax are 

 margined within by a fine interrupted black line, which is pro- 

 bably liable to be wanting. The setiferous punctures of the 3rd 

 elytral interstice are very inconspicuous and difficult to discern, 

 except by their setpe. This species bears a reaiarkable superficial 

 resemblance to the Cistelid, Apellatus nodicornis, Blackb.

Dystrichothorax sloanei, sp.nov. 



PrfBcedenti affinis ; minor ; totus rufo-ferrugineus (elytrorum 

 singulorum disco toto plus minusve infuscato excepto) ; 

 prothoracis lateribus ab angulis anticis usque ad basin rotun- 

 datim nee sinuatim divergentibus ; elytrorum interstitiis 

 paullo magis convexis. [Long. 3-3|, lat. li lines (vix). 



Of very different superficial appearance from the preceding 

 owing to its different colouring, but otherwise scarcely differing 

 ■except in the few character.s specified above. The principal 

 difference lies in the absence of sinuation in the sides of the pro- 

 thorax behind the middle, which makes the segment appear of a 

 bell-shape (its base being its widest part, whereas in D. biculor the 

 prothorax is distinctly wider about the middle than across the 

 base) ; in both species the subdiaphanous lateral margins become 

 gradually wider hindward, but more strongly in sloanei than in 

 bicolor.
