Several weevils injuring orchids are dealt with in this paper and 

 descriptions are given of the following new species : Acythopeus 

 gilvonotatus, found among Phillipine orchids in Washington greenhouses 

 and on Phalmnopsis in New Jersey ; Eucactophagus iveissi, taken ia 

 orchid houses in New Jersey ; and E. biocellalus from a single specimen, 

 received from the Canal Zone, Panama.

The new species of Tachinids here described, which are parasitic upon 

 adult Coleoptera, include Eleodiphaga cajfreyi, gen. et sp. no v., from 

 adult? of Eleodes extricata, Say, in New Mexico, and E. obsoleta. Say in 

 Arizona ; Eleodiphaga poUinosa, reared from an adult of Eleodes 

 hispilabrus, Say, in New Mexico ; and Biomyia eleodivora, described 

 from one individual reared from an adult of Eleodes tricostata, Say, 

 in Nebraska. 



Hall (W. B.). Notes on the Immature Stages of Hemitaxonus 

 multicinctus, Rohwer. — Proc. Entom. Soc, Washington, B.C., xix, 

 no. 1-4 ; March, June, September, December, 1917 ; p. 28. 

 [Received 22nd October 1918.] 



The sawfiy, Hemitaxonus midticinctus, Rohwer, is recorded from 

 cultivated ferns, Athyrium thelypteroides, in Ohio. The eggs are laid 

 late in May on the upper side of the leaf, incubation varying from 50 

 to 60 hours. In rearing cages the feeding stage of the larvae occupied 

 11 to 12 days. There is only one annual generation. It seems 

 probable that this species is only partly controlled by hellebore. 

 The house WTen, Troglodytes domesticus, is an active enemy of the 

 larvae.

 Seeds of Amelanchier. — Proc. Entom. Soc, Washington, B.C., xix, 

 no. 1-4 ; March, June, September, December, 1917 ; pp. 79-86,

The discovery of two species of Chalcid developing in the seeds of 

 the shad bush {Amelanchier canadensis) was recorded by the author 

 in 1914 ; since then, a number of infested berries have been collected 

 and examined. Descriptions are given of the two species reared from 

 the berries, both of which are new to science. Megastigmus 

 amelanchieris, sp. n., described from seeds collected in West Virginia 

 and in Pennsylvania, oviposits in late May and early June, the egg 

 probably being deposited -v^dthin the tissue of the seed. The larva
