After the last molt the larva feeds for about three weeks, 

 during which time it grows very rapidly. It then ceases 

 feeding, burrows a little distance below the surface of the 

 ground and makes a small chamber. The bodv shorten-

 and is accomplished in the same way as the molting in the 

 previou- -tages. In several instances the larva- have molted 

 three times before pupating. 



ri'/m. (Plate 5, Figs. 1, 3.) Eighteen mm. long, 6.4 

 mm. wide at the lirst abdominal segment. Oblong, some- 

 what elliptical and flattened. General color of the body 

 pale amber. Head medium, somewhat flattened in front 

 and strongly depressed beneath the thoracic segments. 

 Kyes prominent, seal brown in color. Antenme and month 

 parts free, translucent. Prothorax broader than long, con- 

 siderably narrowed behind ; meso-thorax emarginate in

front and two-thirds as long as the meta-thorax ; all sepa- 

 rated by well-defined sutures. Wing-covers translucent 

 and extending beyond the third abdominal segment. Ab-

dominal .segments nine in number, the sides of the body 

 protruding beyond the dorsal portions. The lateral edges 

 of abdominal segments two to six are produced to a blunt 

 point, within which is a. slight depression. Penultimate 

 segment slightly depressed; last segment greatly depre-sed 

 beneath the body, and bearing on the posterior margin a pair 

 of small anal stylets. Each of the first iive abdominal seg- 

 ments bears a narrow brush of erect brown hairs, which ex- 

 tends two-thirds of the distance across the segment (not 

 shown in Fig. 1). 'Fhe nine pairs of spiracle- are light 

 chestnut brown, and are situated in the >ame relative posi- 

 tion a- those of the larva; they. -ire larger, however, and 

 elliptical in outline, t!i<>-e on the meta-thorax being the 

 large-t. Legs free, lran-lucci:t ami nearly surrounded by 

 the wing-covers. 



Unfortunately all the larv:e reared to pupa- died before

 spent in tin- stage.
