Descriptions of Larvae and Pupae. 



The following descriptions are based primarily on preserved 

 specimens (in spirit); but a few notes on the living larvae have been 

 incorporated with them. 



Pseudoptynx, sp. 



LaYva{-^\. Vjfigs. 1—3 and 14, and text-fig. A), — Length (exclud- 

 ing jaws 4 mm.) about 12 mm. Head cordate, flattened dorso-ven- 

 trally, somewhat broader than long, widest opposite the middle of the 

 deep posterior sinus. Ocular tubercles (text-fig. A) not very promi- 

 nent, somewhat flattened dorso-ventrally, each bearing six black 

 ocelH all on the dorsal surface. Antennae scarcely reaching to the 

 tip of the ocular peduncle, slightly swollen at the tip. Mandibles

long, perfectly straight as far as the second and longest tooth, then 

 strongly curved inwards to the tip ; third tooth longer than first. 

 Thorax flat : prothorax much narrower than head, broader than 

 long, freely articulated with head and mesothorax. Mesothorax 

 much broader than the head, bearing two pairs of lateral lobes each 

 fringed with hairs — the anterior very large, bent back at an angle in 

 the middle and slightly forwards again close to the tip, the poster- 

 ior smaller, slenderer, and approximately straight. Metathorax 

 broader than mesothorax and fused to it and to the abdomen ; lateral 

 lobes as in mesothorax but smaller, the anterior one not so strongly 

 bent. Abdomen broad and flat ; each segment except the last (9th) 

 broader than long, and produced laterally to form a pair of processes 

 fringed with hairs ; last segment longer than broad, narrower be- 

 hind than in front, truncate posteriorly, without lateral processes,
