thickest at the basal third, and terminated by four articulated 

 spines, one of which is much longer than trie others. A tuft 

 of hair issues from a tubercle at about half its length from 

 base. Details of the head structure are shown at figures 3, 4, 

 5, 6 and 7, and all these are drawn from a cast larval skin. 

 The antennae (figure 4) are consequently a little stouter than 

 normal, and the maxillary structures at 6 rather more widely 

 spread. The mandible at 5 and mentum at 7 are accurate. 

 The hair of maxillary fans is simple. 



The thorax is angular, wider than long, color white with a 

 median black portion becoming wide anteriorly. Abdomen 

 blackish except segments 7 and 8, which are white. Anal 

 segment and siphon black. The siphon is just about twice as 

 long as wide, is a little dilated before the middle, and has the 

 valves a little dilated, so as to flare the tip. Figure 2 is more 

 accurate as to proportion ; figure 8 is from a cast skin and, 

 being flattened out, is a little broader than natural. The anal 

 gills are long and slender, pointed at tip, without obvious tra- 

 chese. The two rows of spines on the siphon consist of seven 

 each, essentially like figure 10, though there is a little varia- 

 tion. The patch on the eighth segment consists' of five scales 

 on each side, shaped as in figure 9 and arranged as shown in 

 figure 8. 



So characteristic is this larva in appearance that it would 

 seem to be difficult to mistake it. The pupa has not been 

 studied.

Male Antenna? brown, of a slightly orange tinge. Thorax and body 

 rich dark brown. Fore wings the same, slightly lighter. Basal line 

 white, wiJe, angulated, inclosing a brown base. This line may lie clear 

 and clean, or it may be produced on the veins as white lines extending 

 from it across to the median white band. Again the white veins may be 

 only two in number, forming a white > of which the apex touches the 

 angle of the line while the ends cross the median space and touch the 

 median white band, the upper one just in contact with the ocellus. A
