In his Appendix Distant states that the difference between Lacco- 

 frephes maculatus (Fab.) and Laccotrephes griseus (Guer.) is that the 

 anterior area of the prosternum in the former is entirely straight and 

 non-tuberculous, while in the latter this area has a strong acute tubercle. 

 I have examined several specimens in the collection of the Zoological 

 Survey of India including one from Lobha and find that the tubercle is 

 present in all of them and there is no specimen, agreeing in size with 

 L. griseus, which is without this acute tubercle. L. maculatus, therefore, 

 does not appear to be represented in this collection.
