I at first thought this insect was a variety of L. virgi- 

 nalis, Gr., but, on going through this group of Limneria, 

 a closer examination proves that it is distinct ; the 

 female appears to he undescribed. I received several 

 specimens bred from Gracilaria stigmatella by Mr. W. 

 H. B. Fletcher. I have also seen specimens bred by 

 Mr. G. Elisha from the same host, and I have taken it 

 myself at Wimbledon and in the neighbourhood of 

 Norwich. It differs from L. virginalis in its smaller size, 

 and in having the hind femora generally more or less 

 fuscous at the base and apex, the front coxae of the 

 female and front and middle coxae of male yellow ; the 

 post-petiole is slender, rather longer than wide, in 

 virginalis it is subquadrate with distinctly projecting 

 spiracles ; the supero-medial area of the metathorax is 

 long and narrow, in the other species it is transverse.

This very distinct Limneria has been taken in the neigh- 

 bourhood of Shere by Dr. Capron, and I have also taken 

 it in Norfolk. In colour it resembles L. diformis, and like 

 it has the transverse anal nervure divided ; the meta- 

 thorax is almost without superior areee, having only a 

 transverse ridge distinct ; the 3rd segment of the abdo- 

 men is transverse, and the aculeus about one-half the 

 length of the abdomen.

Dr. Capron sent me, last year, a Limneria, taken at 

 Shere, which I have little doubt is this species. It is 

 in colour like L. difformis ; the transverse anal nervure 

 is divided ; the areae of the metathorax distinct, five in
