an abundant sending of this species taken at Manila on an unknown 

 tree, and finally the same insect was received June 21, 1912, from 

 D. B. Mackie, Manila, Philippine Islands, on Murraya exotica. The 

 type lot is that forwarded by Mr. Compere, 



Egg.— Size 0.165 by 0.096 mm.; color yellowish; without reticu- 

 lations, stalk attached at larger end (fig. 1). 



Larva, first instar (fig. 2). — Size 0.165 by 0.258 mm.; shape 

 elHptical; color, by transmitted light, light brown. Margin with 

 usually 17 pairs of fine hairs situated on tubercles, of which the first 

 and third caudal pairs, as well as the third cephalic pair, are longer 

 than the others. Dorsal area with three pairs of stout short spines: 

 One pair near the cephalic extremity between the eye spots, one pair 

 at about the middle of the case and one pair cephalad of the vasiform 

 orifice. Vasiform orifice (fig. 3) broad, triangular, with the anterior 

 margin straight; operculum not half the length of the orifice, leaving 

 the setose lingula exposed; size of orifice 0.027 by 0.024 mm. 

 Antennae (fig. 20) composed apparently of four segments, the proxi- 

 mal irregular and large. The others narrow, cylindric, with the distal 

 one very acute and placed at an angle from the others. 



Larva, second instar (fig. 4). — Size 0.357 by 0.27 mm.; shape 

 elUptical; color by transmitted light brown; margin with a series of 

 about 15 pairs of spines, which are thick, short, and spear shaped 

 (fig. 8). The caudal margin has a pair of rather long spine-like hairs 

 The margin itself (fig. 7) is all around divided into a number of areas 

 by irregular divisions extending a slight distance mesad ; dorsal area 

 with three pairs of spines similar to those present in the first instar, 

 and also with a series of minute subdorsal pores, as well as a few other 

 scattered ones. The area around vasiform orifice slightly indicated 

 in this instar. Orifice itself (fig. 5) somewhat triangular, measuring 

 0.065 by 0.039 mm. Operculum similar in shape and extenchng a 

 little over two-thirds the distance to the caudal extremity of the 

 orifice. The inner membrane of the orifice below the operculum and 

 lingula appears sculptured, with reticulate, circular, or irregular 

 markings. Lingula (fig. 6) narrow; not swollen at the tip, part of 

 which is seen below the operculum and which is setose and armed with 

 a pair of rather long spine-like hairs. 



Pupa case (fig. 9).— Size 1.088 by 0.788 mm.; shape ellip- 

 tical; color very dark brown by transmitted fight, with the sutures 

 separating the abdominal segments and a fine markuig off the mar- 

 ginal fiuted area lighter. Eye spots transparent, with their broadest 

 part caudad. Dorsum of case completely covered with layer of wax, 

 though the body segments are evident. From the submarginal 

 area arises a short square-trimmed fringe of wax of same color as on 

 dorsum, which extends out over margin of case. From marginal 

 wax tubes arises a rather fight fringe all around of grayish wax fila-
