about the middle <>f June and pair at the end of the month and die oft' during the 

 summer. An account is given of the internal anatomy of Embia eurichii. TheEinbiidse 

 are regarded as interrelated neither with Termitidse nor Perlidse; nor flo the 

 authors think they have any relation with Psocidse. According to Grassi they should 

 be rankeil as a special suborder parallel with Orthoptera sensu stride under the 

 order Orthoptera. On the other hand the translator of Grassi's papers (which 

 appeared in the original language in 1888-89) regards them as occupying an inter- 

 mediate position between Thysanura and cursorial Orthoptera. 



On Cuterebra emasculator with descriptions of several allied species, D. W. 

 CNmjuillett (Canad. Ertt., 81 (1898), No. l,pp. 9-11). — Five new species are described. 

 They are distinguished by the abdomen being wholly polished, without powder, and 

 with black pleural hairs (Cuterebra tenebrosa); by the same features except the pleu- 

 ral hairs, which are mostly yellow, there being only a small patch of black ones in 

 the male (C. nitida); by the same characters as the last except the black patch of 

 hairs, which is absent I C. polita \: by the abdomen being partly opaque pollinose and 

 by a cluster of black hairs above the center of the pleura, the rest being yellowing 

 (C. lepivora I; and by the same characters as the last except the black hairs, which 

 are absent (C. latifrons). Fitch's type (specimen of C. emasculator) is stated to be 

 identical with C. fontinella of Clark.

The production of sound by beetles, S. Schenkling (Illus. Wchnschr. Ent., 2 

 (1897), No. 18, pp. 973-280, figs. 10). — The various methods of producing sounds are 

 popularly discussed. Considerable space is given to stridulation in the different

"Watering bees — a trough for the purpose, J. C. Cokey (Amer. Bee Jour., 37 

 (1S97), No. 8, p. 115, fig. 1). — For use in the more or less arid regions of the West, where 

 bees must go a long ways for water, the author's device seems excellent. It consists 

 of a large trough made of a sheet of No. 22 galvanized iron 36 by 84 in. with the side 

 turned up 5 in. high, so as to form a kind of immense dripping pau with a capacity 

 of about 30 gal. In this a lath or cleated float, occupying the whole area, is placed, 

 and pipe connection made with a source of water supply. 



Mating queens— how it may be controlled, L. A. ASPINWALL (Amer. Bee Jour.. 

 37 (1897), No. 26, pp. 302. 403 ; from Beekeepers' 13 cine for January, 1S97). — Where one 

 has thoroughbred bees at home, the clipping of the wings of the virgin queen so as 

 to lessen somewhat her powers of flight is recommended. 



Comb foundation — is its use profitable? S. A. Deacon (Amer. Bee Jour., 37 

 (1897), No. 37, pp. 579,580).— -The author argues that the advantages claimed for 

 foundation do not equal its cost. The only advantage that he is able to see is the 

 exclusion of drone cells. It does not, as was once thought, take 20 lbs. of honey to
