APPENDIX. 225 



referred to by Shuckard, I find it registered with the locality 

 Massachusetts; a second example is without a register number; 

 a third specimen, without a ticket of locality, from the Stephen- 

 sian Collection, is a distinct species, although closely resembling 

 T.femorata. 



Page 53. MYRMICA L^EVIGATA. This species proves to be 

 distinct from the M. pallidula of Nylander. I have received 

 specimens of the large and small workers of M. l&vigata ; they 

 were discovered in a hot-house by Mr. E. Parfitt, at Exeter; 

 the species is undoubtedly identical with (Ecophthora pusllla of 

 Heer, the House-ant of Madeira. The large worker of M. pal- 

 lidula differs from the same form of M. pusilla in having the 

 sides of the head nearly parallel ; in Heer's species, the sides of 

 the head are gradually narrowed to the base of the mandibles. 

 The small worker of the latter species has the head conspicuously 

 narrowed before and behind the eyes ; in M. pallidula it is very 

 slightly so. 



Page 89. LARRA ANATHEMA. In the British Museum Col- 

 lection there are four specimens of this insect ; two were for- 

 merly in that of James Francis Stephens, Esq.; none of them 

 have any ticket of locality attached, nor can I find any reference 

 to them" in the Museum registers.
