only 2 are of prime importance in the Pliilippines. " Throughout the Philip- 

 pine Archipelago, and in fact in all southern Asia and the Malaysian regions, 

 the uang, or rhinocerous beetle (Oryctes rhinoceros) causes a tremendous 

 amount of damage. . . . The red weevil (RhynchopJioras ferrugineus) is the 

 second most destructive insect attacking coconuts in the Philippines." 



The enemies and diseases of the coffee tree in East Africa, H. Morstatt 

 {Pfianzcr, 8 (1912), Bciheft 2, />/>. V+87, pis. ;//).— The first part of this paper 

 (pp. 1-74) is devoted to a discussion of the various animal enemies of the coffee 

 tree, of which the insects make up the greater part. 



Forest entomology in the United States, K. Escheeich (Natunc. Ztschr. 

 Forst u. Lcvmlw., 10 (1912), No. 9, pp. J,33-U6, figs. //).— This is a review of 

 the work carried on by the forest insect division of the Bureau of Entomology 

 of this Department, and includes a list of the more important writings on the 

 subject by A. D. Hopkins. 



Tetriginfe (Acridiinae) in the Agricultural Research. Institute, Pusa, 

 Bihar, with descriptions of new species, J. L. Hancock (Mem. Dept. Agr. 

 India, Ent. Ser., 4 (1912), No. 2, pp. 131-160). — Some 24 species are described 

 as new in this paper. 



A new pest to maize, C. French, Jr. (Jour. Dept. Agr. Victoria, 10 (1912), 

 No. 7, pp. .'foO, Ifol, figs. 2). — The harlequin fruit bug (Dindymus versicolor) is 

 reported to have been the source of injury to com at Omeo, Gippsland. The 

 injury is caused by sucking the juice from the kernels at the end of the cob. 



A note on acid-fast bacilli in head lice (Pediculus capitis), G. W. McCoy 

 and M. T. Clegg (Pub. Health and Mar. Hosp. Scrv. U. 8., Pub. Health Rpts., 

 27 (1912), No. 36, pp. 1^/64, l.'i65). — In recent work in connection with the study 

 of the possibility of the transmission of leprosy by animal parasites, the authors 

 have found a large number of acid-fast bacilli in smears made from 2 lice 

 (P. capitis) taken from an advanced case of nodular leprosy. In morphology, 

 grouping, and tinctorial characteristics, the organisms found in these insects 

 were indistinguishable from the leprosy bacillus. 



Leafhoppers affecting cereals, grasses, and forage crops, H. Osborn ( U. 8. 

 Dept. Agr.. Bur. Ent. Bui. 108, pp. 123, pis. .',, figs. 29).— This bulletin is based 

 upon investigations made in the field, on farms and ranges, under natural 

 conditions in various parts of the United States, and deals particularly with 

 those species affecting the cultivated crops. 



On gi'asses and grains the attack is more commonly noticed in the form of 

 wilted or discolored blotches on the leaves or stems. The author believes that 

 the condition known as " silver top," a whitening of the entire upi^er part of stem 

 and head, is at times, in blue grass particularly, caused by leafhopper attacli. 

 The puncturing of the tissue and pumping of the plant juices result in more or 

 less loss and drain on the plant, the importance of the attack depending upon 

 the abundance of the insects. "All of the crops belonging to the grass family and 

 most of those in general cultivation belonging to the legumes are infested by one 

 or another, often by many, species of the leafhoppers. The abundance and cor- 

 responding injury vary greatly with these crops for different parts of the 

 country and under different cultural conditions, as also with different seasons. 

 . . . For the wheat, oats, rye, and barley crops the most important species 

 are, in the North and Northwest, Cicadula 6-nntata and Athysanus cxitiosus, 

 and in the South A. exitiosus and Drwculacephala reticulata. For the grass 

 crop, including timothy, brome grass, and blue grass, the most important species 

 are Deltocephalus inimdcvs, D. affinis, D. configuratus, Dr(rculacephala molUpcs, 

 and Phlepsius irroratus. For clover, alsike, alfalfa, soy beans, and leguminous 

 crops the most important are Agallia sangudnolenta and Empoasca mali. The
