Description of the Larva of Eupithecia linanata. — Short and stumpy, slightly 

 tapering towards the head. When young bright yellow, with blackish dorsal spots. 

 When full-fed yellowish green, with a series of large dull olive or rust-coloured dorsal 

 spots or bars, running the whole length, and bordered on either side by a dusky olive 

 line. Head nearly black. Belly dusky. Spiracles black. Body sprinkled with short 

 whitish hairs, and here and there studded with black tubercles. The dorsal markings 

 are frequently very indistinct, and sometimes wanting altogether, aud the larva is one 

 uniform yellowish green. Feeds in August and September on the flowers and seeds 

 of the common wild snap-dragon {Linaria vulgaris). It is uncertain in its appearance, 

 being one year exceedingly abundant and the next very scarce. The pupa, which 

 is enclosed in an earthen cocoon, has the abdomen reddish yellow, tip blood 

 red, thorax and wing cases olive. The perfect insect appears in May. In very hot 

 seasons it is sometimes double brooded. — H. Harpur Crewe ; Medstead, Alton, Hants,

Description of the Larva of Eupithecia subfulvata. — Long, tapering but slightly 

 towards the head. Reddish brown, with a series of dusky olive oval dorsal spots, con- 

 fluent towards the head and tail, and connected and intersected by a central dorsal 

 line, paler in colour than the spots. Spiracular line white. Subdorsal lines black, 

 interrupted. Back thickly studded with minute white tubercles, and less thickly with 

 whitish hairs. Belly whitish, with a central purplish line running the whole length. 

 Feeds in September and October on the flowers and seeds of yarrow {Achillcea mille- 

 folium). Pupa enclosed in an earthen cocoon ; uniform, orange red, thorax and wing 

 cases paler than abdomen. Tip of latter blood-red. Long, rather slender and tapering. 

 Abdominal divisions deep red. W^ing-cases much furrowed. The perfect insect 

 appears in June and July. I prefer retaining the name E, subfulvata, as the foregoing 

 description was taken from larvae reared from eggs of this so-called variety of E. suc- 

 centuriala. I shall continue to believe that the two insects are distinct species till 

 some person breeds one from the egg of the other. I never heard that this has been 

 done. The exhibition of a long series of varieties running one into the other proves 

 nothing at all. It has never been my good fortune to be in a locality where E. succen- 

 turiata occurred, so that I have never been able to try the experiment. I shall feel 

 deeply indebted to any gentleman who is in the habit of taking this insect if he will 

 send me a few eggs or a living female. — Id. 



Drawings of the Genus Eupithecia. — I am at present drawing and colouring from 

 Nature, in the ' Manual,' the Genus Eupithecia. The following species I do not possess, 

 E. consignata, E. pernotata, E. egenaria, E. pusillata,* E. irriguata, E, indigata* and E. 

 expallidata. Those marked with a star I have only poor specimens of. If any col- 

 lector would be so obliging as to lend me a specimen of these species, for the purpose 

 above named, I should feel very much indebted to him. The utmost care shall be 

 taken, and postage of course paid both ways.—/. Greene ; Cuhley Rectory, Doveridge,

Larva of Caradrina cubicularis in Wheat-ricks. — After reading M. Guenee's de- 

 scription of the habits of the larva of Apamea basilinea (Noctneliles, vol. i. p. 205) I 

 thought I should have no difficulty in obtaining the perfect insect, which, although 

 pronounced by the ' Manual ' to be " common everywhere," is not, according to my 

 experience, so common here. I accordingly sought among corn-ricks and on barn 

 floors for the larvae. In the winter of last year, and early in the spring of this year, I 

 was present at the removal of several corn-ricks from the field to the barn, and as the
