NOTES ON LACHNOSTERNA. 



to find those of the more common species. Nor do we know liow lon{ 

 they remain in the larva stare — more than one year certainly, possibl 

 three. Will not our coleopterological friends try and work out some 

 of these problems .' There are plenty of them. 



EXPLANATION OF PLATES XLVII1-LX. 



The figures are consecutively numbered, but not regularly arrangec 

 on the plates. In each case the number of the figure corresponds to th( 

 number of the species in the text, and each group of figures refers tc 

 the same species. The lettered figures throughout have the same 

 meaning: a, claspers of male from front or above; b, right clasper ; c 

 leftclasper; tf, female organs. These are always subdettered as fol 

 lows: /, inferior plates; s, superior plates; p, pubic process. Other 

 special letterings are explained as they occur. Missing numbers repre 

 sent the numbers of species not studied.
