about a week after deposition. The larva has four moults, and 

 becomes mature in from two to three weeks. The reddish pupa 

 is suspended by the end of its abdomen from a leaf. The beetle 

 hibernates as an adidt, and becomes active from the end of April to 

 the beginning of May. The adults of the next generation appear in 

 the middle of June, and after this, the generations become quite 

 irregular and two or three broods may occur before hibernation takes 

 place. 



It is infested by two parasitic flies ; one attacks the hibernating 

 adults, the larva appearing in March or April and soon pupating, and 

 the adult fly emerging at the end of May ; the other infests the pupa, 

 and the fly appears in June. Possibly this species has several genera- 

 tions in a year.

The author describes the specific differences displayed in the 

 prothoracic shields of the larvae of six species of Cerambycids, viz. : — 

 Apriona nigicoUis, Chevr., Melanauster chinensis, Forst., Chreonoma 

 fortunei, Thorns., Oberea japonica, Thunb., Xylotrechus pyrrhoderus, 

 Bot., and Thyestes gebleri, Fald. He also states that though Oberea 

 japonica has been thought to be an important apple-tree borer in 

 Japan, the damage it does should really be attributed to Apriona 

 rugicollis, which also attacks mulberries.

The author has discovered on the mulberry-tree a new gall-making 

 Cecidomyid, which is here described as Diplosis morivorella. The 

 galls are greenish, plum-shaped, of a length of 5-9 mm. and are found 

 in groups at the base of new buds or on the stalks of the basal leaves 

 of young shoots. The larvae usually appear at the end of May and 

 pupate at the beginning or middle of June within the gall. The 

 adults appear from the middle of June to the beginning of July and 

 oviposit in the buds ; they live about a week after emergence. From 

 two to twenty eggs are laid by a fly in a single bud. Infested buds 

 may fail to develop, but as it is the basal, and not the apical ones 

 that are attacked, the total injury may not be serious.
