Ttrniocawpa opima: These ova have been sent to me several 

 times wild laid, in April and May, and always in a large irregular 

 cluster near the tip of a young shoot of Salix repens, superimposed 

 in places to a depth of 3 or 4, so as to fill up the interstices 

 between the leaves ; probably 200 or 300 eggs in a batch is quite a 

 usual number. In shape and sculpture they are similar to those 

 of T.(iothica, but smaller, being only -SSmm. in diameter and -Somm. 

 high ; and in those I have examined the average number of vertical 

 ribs has been rather less, that ^is to say 44. I have not seen any 

 in a freshly laid state, but when mature, the colour is pale purplish, 

 and later dark slatey grey. 



Taniocampa (/racilis I have found very frequently in early 

 May, always tucked away on a dead knapweed head, and though 

 very few may be apparent superficially, quite a large number 

 will be found if the seed vessel is carefully pulled to pieces. 

 The moths seem to prefer those plants which are standing in 

 rides and open spaces in woods. The egg is globular, flattened, 

 and somewhat shiny. Shell thin, and very faintly sculptured 

 on the upper half with about 50 vertical ribs. The base is 

 smooth or nearly so. In colour, it is white when newly laid, 

 and pale yellow or brownish later, turning dark as usual before 

 hatching. Diameter, -Gmm., and height •4mm. 



Culyimiia affinis. — Two eggs laid on the bark of a small elm- 

 twig, parti}' superimposed, and with no suggestion of being hidden 

 away in any sort of crevice, produced this species. Pale lemon- 

 yellow in colour, upright, and with 36 vertical ribs. The 

 sculpturing is rather shallow. In shape they were nearly spherical, 

 but rather flattened below. Diameter -Somm., height •45mm. 



Cirtiuedia jcevampelina. — These ova, so far as I am aware, are 

 laid singly at the base of a winter bud of ash ; sometimes two on a 

 twig, and occasionally on the bud itself. They are invariably 

 partially covered with parental hair-scales. The ovum is upright, 

 hemispherical, rather flattened, and has bold and well-defined 

 sculpture. This takes the form of 21 vertical ribs, of which ten 

 stop just over the shoulder, so to speak, and the remainder are 

 carried up to the micropyle. Between these ribs are numerous 

 lateral rungs. The colour is at first pale yellowish-white, 

 becoming deep purplish-brown when matured. They appear to 

 hatch just before Christmas. Diameter -TSmm., and height •4mm. 



Cinhia citrcufo oviposits singly on twigs of lime towards the end 

 of the branches, and usually on a leaf-scar just below a bud; 

 sometimes two or three on a twig. There they remain throughout
