with his description entirely, and is clearly not the species 

 regarded by MacLachlan as elegans. S. elegans of Stephens is 

 the larger form, with the veins entirely dark fuscous, as stated 

 in his description ('111. Brit. Ent.,' Mand. vi, p. 113, 1836), and 

 is therefore synonymous with striatellus, Klap. Other specimens 

 of the same species were labelled by Stephens as marshami and 

 bechvithii respectively. 



Having determined the larger species as elegans, Steph., it is 

 now necessary to find a name for the smaller form, and I think 

 we shall be safe in accepting Morton's suggestion and adopting 

 the designation of S. pygmaeus, Eambur. Eambur's description 

 (' Ins. Nevropt.,' p. 442, 1842) leaves the species somewhat ill- 

 defined, but Brauer's later diagnosis (' Neuropt. Austr.,' p. 56, 

 1857) admits of no doubt, at all events, as to his conception of 

 Eambur's species. ->_n'. 



The following comparison is adapted from Morton, an^ ampiy 

 serves to separate the two species under consideration : 



Face dark shining piceous ; dorsum of thorax also 

 brown ; neuration of fore wings entirely fuscous witho? 

 ruptions, these wings heavily marked to the wing base, bi 

 more or less radiate, especially those proximal to the midcu. 

 of gradate veinlets, those in the distal part of the wing much bro. 

 up into irregular dots ; gradate veinlets usually heavily shaded. 

 Larger darker species. 



elegans, Stephens (= striatellus, Klap.). 



Face and dorsum of thorax yellowish ; neuration of fore wings 

 with pale dotted interruptions ; dark markings on outer half of fore 

 wings mostly placed opposite each other on either side of the dark 

 portions of the longitudinal veins. A pale space at the base of these 

 wings in which the veins are rather indistinct, the transverse vein- 

 lets being hardly visible. Paler smaller species.

ON THE EAELIEE STAGES OF CACOECIA 

 CRATAEGANA, HUBN. N 



By W. G. Sheldon, F.Z.S., F.E.S. 



In the month of June, 1917, searching for larvae and pupse 

 of Peronea boscana on elm at Brockenhurst, I found a pupa 

 spun up in an elm leaf which produced a male specimen of 

 Cacoecia crataegana, generally supposed to be attached to oak. 

 Three years later, at the same period of the year, I beat out of 

 elm at Brockenhurst several very large, dark olive green, almost
