eyes ; maxillary palpi obscure. Head, thoracic, and abdominal append- 

 ages as in type. Only a very narrow slip of the first femur is seen between 

 the maxillae and first legs. Antennae slightly longer than body. There 

 is a small dorso-lateral ridge on all abdominal segments. The meso- and 

 meta-thoracic dorsal setae are long and slender, and directed upwards 

 and outwards ; only the dorsal setae found on segments 1 and 2 ; they 

 exist on all the other abdominal segments except the last, and are 

 directed caudally ; the dorso-lateral setae in segments 3, 4, and 5 are 

 characteristic, being extremely long and slender, those on segment 3 being 

 the longest and as long as the width of the body at this part ; they are 

 all mounted on prominent tubercules at the cephalic end of the lateral 

 ridges, and project upwards and outwards. The dorso-lateral setae on 

 segments 6, 7, and 8 have a similar position, but are small and directed 

 caudally ; there is a minute lateral seta ventral to and below the spiracle 

 close against the outer or dorsal margins' of the wing, and is found in 

 segments 3-7 inclusive. All other particulars as in type. Tenth abdominal 



segment bi-digitate.

Dehiscence. 



A transverse split along the epicranial suture frees the frontal head- 

 piece, with its cephalic plate, antennae, labial palpi, and maxillae, all in 

 one piece, and this is forced forward, but retained in its lower extremity 

 by loose slips ; the first and second legs form a separate piece on either 

 side, but are retained more or less in position ; a mid-dorsal splitting cleaves 

 the vertex, prothorax, and upper two-thirds of the mesothorax.
