consisting of from 45 to 50 such hairs; nearer the base and closer 

 to the median Hne are small hair-bearing areas with one large and 

 one small hair, the larger being the more proximad, the other lying 

 outside it. Segment 4 is hidden by the leg-pads but the hairs are 

 present. 



Tergites with four small tubercles on the dorsal side of the 8th 

 segment, the more caudal pair being the larger, the cephalic pair a 

 little smaller. Segments 1 to 7 (Plate II, Fig. 8), with six groups 

 of hairs arranged as follows: A cephalic group near the lateral 

 margin of the chitinized portion of the segment, consisting of two 

 hairs; directly caudad of this group near the caudal margin of the 

 segment, a second group of two hairs; proximad and very slightly 

 cephalad of this latter group is a third group consisting of a large 

 inner hair and a smaller outer one. 



Segments 2 to 7 have the fleshy wrinkled pleural region rather 

 extensive, one small hair immediately caudad of the spiracle. Eighth 

 segment with a few scattered hairs near the caudal margin, these 

 hairs being ventral, two pairs; lateral, one pair; subdorsal, about 

 three pairs. Ninth segment with the tergal lobes rather conspicuous, 

 directed sharply dorsad, the extreme tip a chitinized tooth (Plate 

 II, Fig. 5). 



Length : From crest to the tip of the abdomen, 9.2 mm. 



Dextro-sinistral width at the wing-pads : About 1.6 mm. 



Length of the breathing-horn: 1 mm.
