The mature larva found in the gall is about 7 to 8 mm. long and 

 1.9 mm. broad. Tts color is whitish to pale yellow, occasionally 

 light pinkish. Its body is thinly covered with hairs which are 

 slightly brownish, especially on the head and abdomen. The legs 

 are not much elongated. They look like blunt, lobular, fleshy pro- 

 jections. The dorsum of both thorax and abdomen has its surface 

 somewhat wrinkled. On the sides are found two rows of lobes of 

 the skin, extending from the prothorax to the abdominal end. Now 

 the forked abdominal end is horny in structure. The mandibles are 

 large, pointed at the tips and broadened at the base. The labrum 

 is very small compared with other parts of the mouth. The other 

 parts are not so much chitinized as the mandibles. The maxillary 

 palpi, galea, stipes, ligula, etc., are thin and light brown in color 

 (Fig. 5, Plate II). 



Pupa. — At the beginning of pupation the body of the animal is 

 soft and the pupal skin is perfectly white. Neither similar to the 

 larva nor to the adult, the mouth-parts of the pupa have the maxillae 

 much longer than the mandibles. Except the tips of the mandibles, 

 which are slightly chitinized, the entire mouth-parts are soft. The 

 antennae are placed latero-dorsad and their segments are not very 

 distinctly visible. The compound eyes have been developed within 

 the pupal skin. Both elytra and inner wings are hollow, sheath- 

 like, more or less convex-flattened and gradually narrow up towards 

 their tips. The legs have been developed in their full length and 

 the hind ones are placed crosswise on the ventral side. The abdo- 

 men has transformed to the general shape of that of the adult 

 within the transparent skin (Fig. 4, Plate II). 



When the pupa is getting old its color becomes darker, 

 especially on its head. The elytra and the inner wings now are 

 placed latero-ventrad. The eyes, antennas, mouth-parts, legs, and 

 the elongated tail-like abdomen are brownish black, like those of 

 the adult. 



Data on occurrence, season, etc. — The beetle has its larval stage 

 much longer than either the adult or the pupal. The first occur- 

 rence of the larva just hatched out from an egg on the surface of
