downvvards; then follow two corrugations without spines, and 

 hcreaf ter tlic same arrangement is repeated ; thèse segments are 

 eacli devided into four corrugations and the spines are placed on 

 thc two middle oncs; on the first abdominal segment and on the 

 mcso'and metathoracal segments thèse are six spines on each on 

 onc corrugation, and on the first abdominal segment also three 

 at the side. At the postcrior eud the bod)' terminâtes bclow with a 

 somewhat cushion-shapcd part, and abovc it is a cavity in which 

 the brown postcrior spiracles lie close togcthcr, but not on auy 

 procsss; each spiracle shows three slits; tlic anterior spiracles arc 

 small, phîoed above tlie prothoracal segment on each side. The larva 

 is gresn with a yellow or whitish-yellow line along the dorsum and 

 a narrower and somctimes less distinct linc along each side. Thc 

 pupa is elongated ovatc, broad and rounded in front, not much 

 tapering behind ; it bas the same spines or hairs as the larva; the 

 postcrior end is bent a little downwards and abovc it are the pos- 

 tcrior spiracles in the same cavity as in thc larva. The pupa is at 

 first green, later on it becomes more brown and more pellucid, 

 and the enclosed fly is then distinctly seen through the puparium. 

 The length of the pupa is about 9 mm. The pupa rests attached 

 with the posterior end to some leaf or stalk, but Martelli records 

 that at time of pupation the larva leaves the plant and goes 2-3 

 cm. into the earth and pupates there. According to Martelli the 

 eggs arc elliptical in shape, 1.13-1.26 mm. .long, of milk-wliitc 

 colour, with the shcll ornameuted; they are deposited singly on 

 leaves with Anhids; the same author gives interesting notes about 

 the copulation and tells that the fcmale flies with thc nuile on the 

 dorsum to a secure place; he gives the duration of thc copulation 

 as about three hours."
