Dascillus cervinus as a marshy meadow pest, W. Hebold (Centbl. Balct. 

 [etc.}, 2. AU., 33 (1912), No. 17-19, pp. 438-U2, pl. 1, figs. 6).— The larva oi 

 this beetle is reported to have been the source of injury to meadows in the 

 southern part of the Province of Posen. 



A new enemy of the coconut palm, G. Herschee and L. Millot {Abs. in 

 Internat. Inst. Agr. [Rotne], Bid. Bur. Agr. Intel, and Plant Diseases, 2 {1911), 

 No. 6, pp. 1552-1554). — ^A small nocturnal beetle of the genus Hylecoetus, the 

 larva of which bores in the trunk, is reported to be a serious enemy of the 

 coconut palm all along the northwestern coast of Madagascar. 



A grove of deformed trees, R. J. Teeey (Science, n. ser., 35 (1912), No. 905, 

 p. 115). — A grove of 400 or 500 small persimmon trees in St. Louis County, Mo., 

 is said to have suffered from the ravages of beetles (Oncideres cingulata), 

 limbs of young and old trees varying in diameter from 5 to 15 mm. (from 0.2 

 to 0.6 in.) being girdled and the ends falling to the ground. The girdling is 

 said to be done mainly in September and October. 



" There is no tree in the grove that does not present crooked trunk and limbs. 

 The deformities in some cases are extreme. Most of the trees are as a conse- 

 quence dwarfed, although able to make some advance in growth." 



On an enemy of the coffee tree, L. Dupobt (Bui. Econ. Indo-Chine, n. ser., 

 U (1911), No. 90, pp. 392-397, fig. 1).—An account of Xyleborus coffew and its 

 injury to Coffea robusta in Indo-China.

 Afric. [Brussels], 1 (1912), No. 3, pp. S36-3J,6, pl. 1, figs, ii).— Twelve species 

 are here dealt with, namely, Diamerus flci, Phlceotribus puncticolUs, Stephano- 

 deres congonus n. sp., S. hevece n. sp., Hypothenemus tuherculosus n. sp., Cryp- 

 tarthrum walkeri, Xyleborus afflnis, X. ambasius n. sp., X. camerunus, X. cogna-

A new enemy of the Douglas fir (Pseudotsuga douglasii), M. de Koning 

 (Abs. in Internat. Inst. Agr. [Rome], Bui. Bur. Agr. Intel, and Plant Diseases, 

 2 (1911), No. 6, p. 155-'f). — The beetle Strophnsomus obesus is said to have de- 

 stroyed the annual shoots of Douglas fir in the Province of North Brabant, 

 Netherlands, young trees being most severely injured. Gradually the dead 

 branches lose their needles and nothing remains but dry wood. Careful ob- 

 servation shows that the bark at their base has been eaten away. As the 

 injured branches live on for some time, the sap which oozes out sometimes 

 forms a thickening just above the wound.
