 were typical Reds. Those Reds were paired, and in 1908 the brood (a small one) 

 produced 25 per cent, of the yellow form ; (c) Camptogramma fluviata, a varied 

 series bred from ova laid by a ? taken at Eastbourne ; and (d) a yellow aberration 

 of Noctua rubi from Yorkshire. Dr. F. A. Dixey, a number of Central and South 

 American butterflies belonging to sis different subfamilies, but all showing the same 

 obvious character of a diagonal reddish band on a general dark surface. He stated, 

 in reference to some general remarks by Mr. W. J. Kaye on a previous occasion, that 

 although there was no direct geographical continuity between the areas of distribu- 

 tion of several of the species shown, there appeared to be sufficient connection of an 

 indirect kind to warrant the supposition that the whole constituted an assemblage 

 of mimetic character.

SELANDRIADES (continued) ERIOCAMPA and P(ECILOSOMA. 

 BY THE EEV. P. D. MORICE, M.A., F.E.S. 



Four genera besides those already discussed in these pages 

 complete the list of our Selandriads. These are Eriocampa, Hig., 

 Pcecilosoma (originally called Poecilo.stoma, Dhlb.), Emphytus, Klug, 

 and Taxonus, Htg. In all the humeral area is crossed by an oblique 

 nervure. 



Eriocampa, Htg. 



Of this genus as re-defined by Konow we have only one recorded 

 species, the well-known ovata, L. In Mr. Cameron's Monograph six 

 other species appear under the name Eriocampa, but these have been 

 removed by Konow from the Selandriads to the lloplocampids, and 

 I have already dealt with them as such under the name Eriocampoides, 

 Kuw., in No. 17 of these papers (Eat. Mo. Mag., Jan., 1907). 



E. ovata $ is an extremely common and easily re ognised insect. 

 It is something like a highly magnified Tomostethus dubius — black and 

 shining with blood-red pro- and mesonotum ; but the humeral area in
