208 C. B. HARDENBEEG. 



declivous^ slightly concave transversely. Mesothorax massive, 

 slightly convex dorsally; metathorax longer than the 1st 

 abdominal segment. Abd. segments 1 to 4 smooth, without 

 spines ; 5 to 8 with a short, transverse, dorsal row of small 

 spines at the anterior edge. Cremaster rudimentary, con- 

 sisting of a pair of minute, blunt, conical hooks. 



Female Pupa. — Length 7 mm., width 2-5 mm., greatest 

 Avidth at 6th abdominal segment. Head and thorax of pupa 

 membranous, with only a very slight amount of chitinisation 

 on the dorsal aspect of the thoracic segments. First abdo- 

 minal segment membranous over its anterior half; other 

 segments normally chitinised (text-fig. 19, r). Colour of 

 heavily chitinised parts (i.e. dorsal aspect of abdominal 

 segments and all parts from posterior half of 5th abdominal 

 segment caudally) black; remainder of chitinised parts Hay's 

 brown (XXIX), dorsal aspect of membranous part cinnamon 

 (XXIX), spiracles and leg-scars cinnamon (XXX). Surface 

 matte. Dorsal aspect of abdominal segments transversely 

 striate, less pronounced on 6th segment and posteriorly. 

 Anterior, membranous part very much wrinkled, so that no 

 <Ietails can be made out. 



Adult Female. — Apterous, vermiform. Length 7 mm. 

 Head deflected, concealed by prothorax, retractile (text- 

 fig. 19, g). Head subquadrate ; pigment spots (eyes) elongate, 

 triangular; buccal opening transverse, oval. On each side of 

 this the head is prolonged into a short, conical prong, those 

 of the two sides being slightly divergent. Prothorax large, 

 anterior part deflected; spiracles large, prominent. Thoracic 

 segments chitinised on dorsal and lateral aspect only, ventral 

 aspect membranous. Thoracic legs rudimentary, represented 

 by two small membranous protuberances, those on the 3rd 

 segment the largest and connected by a common base. 

 Remainder of body membranous, transparent, sparsely covered 

 with scale-like hairs. Ovipositor short, truncate, conical, 

 membranous, apparently without supporting chitinous rods. 

 Oolour of body amber yellow (XVI), chitinised parts (exposed 

 portion) deep chrome (HI).
