ened, but finely fluted and minutely crenulated. Three marginal de- 

 pressions and radiating dorsal patches as described below in the pupa. 



Pupa-case very pale yellow, or greyish ; dorsum very slightly con- 

 vex ; form roundly elliptical or subcircular ; length about one-twentieth 

 in. as a rule, but reaching one-fifteenth in. The enclosed pupa is con- 

 spicuous dorsally, dark brown, the segments fairly distinct ; on turning 

 over the case the rudimentary- feet may be made out rather confusedly, 

 and the antennae more faintly. Dorsum of the case marked with radiat- 

 ing stria?, more clear than those of the larva : these striae are most con- 

 spicuous near the margin, which is not at all thickened, but marked with 

 narrow but deep channels dividing it into broad segments. At three 

 points in the margin there are small concave depressions, one on each side 

 opposite the rostrum, and one at the abdominal extremity. Correspond- 

 ing with these, on the dorsum, are three very faint radiating dotted 

 patches : when viewed by transmitted light, these patches are seen to be 

 formed of a lace-like pattern, with small, irregular cells, and at their 

 extremity they end in a circular orifice deeply crenulated ; the anterior 

 pair extend from the rostrum to the margin, the posterior one from the 

 vasiform orifice to the margin. Vasiform orifice with straight anterior 

 edge, sides and end regularly convex ; operculum nearly covering the 

 orifice, and of similar form ; lingula short, almost regularly cylindrical, 

 scarcely extending beyond the operculum. There is no marginal fringe, 

 nor are there any dorsal or marginal hairs. 



Adult form unknown. 



Hah, In India, on Eugenise jambolaw. My specimens were sent 

 by Dr. Alcock, Superintendent of the Indian Museum, Calcutta. From 

 the great numbers on the leaves it would seem that the insect is injuri- 

 ous. They came from Poona. 



A short description of this insect was sent by me to Dr. Alcock for 

 insertion in " Indian Museum Notes j" but I have included it again here 

 in order to note the distinctions which separate it, firstly, from A. euge- 

 nise, var. aurantii, next described, and secondly, from A. citri (Ashmead), 

 Riley and Howard, Insect Life, 1893, p. 219. As to the first my descrip- 

 tions and figures will suffice. From A. citri the species differs in the 

 entire absence of marginal and dorsal hairs in the larva and in the three 

 radiating lace- work patches, of which no mention is made by Riley and 

 Howard, but which are conspicuous characters of A. eugenise. 



This insect and its variety, with A. citri, A. melicyti, and others, may 

 be placed in a series of which A. proletella, Linn., may be taken as the 

 type.
