ments, and beyond tlaem this ground-colour imperceptibly is changed 

 to a faint flesh-colour, in some instances a very pale tint of drab ; the 

 small dark brown and shining tubercular dots, each furnished with a 

 fine hair, are ranged on either side of the back iu twos forming in 

 line along the sub-dorsal region, those on the front of the thirteenth 

 segment are large and squarish ; the anal plate is of the same dark 

 brown colour and rather heart-shaped ; a single row of dark brown 

 dots is along the side and othei'S are beneath ; on either side of the 

 second segment is a largish black-brown shield-like glossy spot in 

 front of the spiracles ; another, similar, occurs on the outside of each 

 anal leg, the ocellated spot on either side of the third and twelfth 

 segments is black with white centre ; the skin generally is soft, smooth 

 and glistening : some individuals show a faint purplish-brown dorsal 

 line, while others have only a faint darkness sliding to and fro beneath 

 the skin of the seventh aud eighth segments. 



AVhen full-fed the larva envelopes itself in a pearly-greyish oval 

 cocoon of silk about 8 mm. long by 3 in diameter, smooth within but 

 thickly covered outside with grains of frass spun together and situated 

 generally in some excavated portion of the pod it has fed in. 



The pupa is from 5| to 6 mm. in length and is of an ordinary 

 form, with prominent eye-pieces and longish wing-covers ; the tip of 

 the abdomen ending in an excessively small round thorny boss ; its 

 colour darkish bronzy-brown and shining.

NOTES ON CEETAIN MICRO-LEPIDOPTEEA. 



BY ARTHUR G. BUTLER, F.L.S., F.Z.S., &c. 



Finding it necessary to go through Professor Zeller's paper on 

 "Exotische Microlepidoptera " in the "Horse Societatis Entomologicse 

 Rossicae " for 1877, before attempting to do anything further with an 

 American collection in my hands, I was enabled to recognise several 

 synonyms which I think it important to put on record. 



The genus Donacoscaptes is very closely allied to, if not identical 

 with, Walker's genM% Ertzica from Java (Lep. Het. Suppl., v, p. 17GS): 

 if identical, "Walker's name will take priority. 



Argyria ohliqueUa, Zeller, is my Argyria Candida, which it will 

 supersede : both are described from Japan. 



Melissohlaptes gularis, Zeller, is my M. tenehrosus, which it will 

 supersede : both are from Japan. 



Anchoteles perforatana, Zeller, ia Walker's JJzeda torquetana from 

 Hio Janeiro (Lep. Het., xxviii, p. 443), of which it will be a synonym.
