Atraclomorpha hedeli, Boliv., appears once a year, in July, and the 

 winter is passed in the egg-stage. The adults and nymphs attack 

 the leaves where beets are grown near weeds. LachnosLerna diom' 

 fhalia, Bates, appears as an adult in June, passing the winter as a 

 larva. The beetles hve just beneath the earth and eat the foliage at 

 niglit. The larvae attack the young roots. Eggs are laid half an 

 inch deep and pupation takes place 1-2 inches below the surface. 

 Bolijcoris haccarutn, L., appears twice a year, in May and in June, 

 and the winter is passed as an adult. The nymplis suck the leaf and 

 flower-buds. 



A beneficial Carabid beetle, Calosoma cJdnense, Kirby, is also des- 

 cribed, several cases having been observed of its preying on Noctuid 

 larvae attacking beet. It has probably one annual generation, and 

 hibernates in the larval stage.

 as the Host of the Pediculoides Mite]. — Sangyo Shimjw (Journal

Although it is recognised that the silkworm pupa is the most favoured 

 host of the parasitic mite, Pediculoides, this is dependent upon the 

 maturity of the pupa. The authors' experiments showed that para- 

 sitism by the mite is only readily elYected up to the fourth day after 

 pupation by the silkworm. This may chiefly be due to the fact that 

 the silkworm pupa is by this time far more strongly chitinized, and 

 the mites are incapable of finding their way into the host's body.

In all, 38 new species are described, belonging to 8 genera, 3 of which 

 are new. The majority (25) belong to the genus Eriophjes ; 4 to 

 Phyllocoptes ; 2 each to Epitrimerus, Tegonotus, and Oxypleurites. 

 For the remaining 3 species the genera Phytoptochetus and Cecidodectes 

 of the subfamily Eriophyinae and Diptilomiopus (Phyllocoptinae) 

 have been erected. Eriophyes gastrotrichus, sp. n., is recorded from 

 sweet potato {Ipomoea batatas). Keys to the species of Eriophyes and 

 Phyllocoptes are given. There are also two lists, one of the gaUs and 

 their producers, arranged according to plant orders, and another of 

 the mites concerned.

The title indicates the subject-matter of this paper which concludes 

 with a key to the species dealt with.
