is given by W. V. King (pp. 16-27) ; a review of Rocky Mountain spotted fever 

 eradicative work conducted by tbe U. S. Public Healtb Service in the Bitter 

 Root Valley, Montana, is presented by L. D. Fricks (pp. 28-31) ; and a sum- 

 mary of a Report to tbe Montana State Board of Entomology Concerning Fly

Report of the entomologist, R. H. Van ZwALuwENEtoRG (Porto Rico Sta. 

 Rpt. 1914, pp. 31-35). — The author briefly reports on the occurrence of insects 

 in Porto Rico from October 16, 1913. 



The principal work of the past year has been with enemies of coffee and 

 coffee shade trees, including tbe coffee leaf miner {Leucoptera coffeella) ; a shot- 

 hole borer, Xylehorus sp., which works in guama and guava ; an undetermined 

 pink coccus, attended by Myrmelachista ambigua ramtilorum on the branches 

 of guamfi ; and a flannel moth, Megalopyge Jcrugii, abundant on guamd. The 

 coffee leaf miner is said to be parasitized by two chalcidids, Chrysocharis livida 

 and Zagrammosoma muUUineata. M. krugii is very commonly parasitized by 

 Chalcis ovata and an undetermined tachinid. Micrococcus nigrofasciens, the 

 cause of a disease of May beetles, is said to be native to Porto Rican soils and 

 apparently widespread. A brown "woolly bear" caterpillar, Ecpantheria 

 eridanus, was fairly common on orange trees in the Mayaguez district. The 

 small sweet potato weevil (Euscepes (Cryptorhynchits) Mtatce) made its ap- 

 pearance in tbe station planting during the winter months. Silk oak trees 

 (GreviUea roMsta) are sometimes severely attacked by the fringed scale 

 (Asterolecanium pustulans). 



Tenth annual report of the state entomologist and plant pathologist for 

 1914, G. M. Bentley {Ann. Rpt. State Ent. and Plant Path. Tenn., 10 {19U), 

 pp. 92, figs. 28). — ^This is the usual annual report upon nursery inspection and 

 other work (B. S. R., 31, p. 248). Two species of strawberry-root lice (Aphis 

 forhesi and Macrosiphum fragariw) have been found to be destructive in Ten- 

 nessee, one or the other having been found in 25 of the 96 counties of the 

 State. Descriptive and biological notes are given of the two pests. 



Injurious insects and other animals observed in Ireland during the year 

 1913, G. H. Carpenter (Econ. Proc. Roy. Dublin Soc, 2 (1914), No. 9, pp. 142- 

 160, pi. 1, figs. 8). — This, the author's usual annual report (E. S. R., 29, p. 

 555), deals briefly with the occurrence of the more important insect pests in 

 Ireland during the year. Among those mentioned are the frit fly (Oscinis frit), 

 the migratory apple aphid (Aphis fitchii), the giant willow aphid (Lachnus 

 viminalis), the ox warble (Hypoderma bovis), etc. The author records the 

 extraction of a fourth stage or mature larva of H. bovis fi-om the back of a 

 horse. 



[Reports of the entomologist of Southern Rhodesia], R. W. Jack (Rpt. Dir.

 annual reports deal with the occurrence of and work with the more important 

 insect pests in Southern Rhodesia. 



[Insect pests in Mauritius], D. d'Emmerez de Chaemoy (In Summary of 

 Investigations Made During the Period July 1 to November 30, 1914. Mauritius: 

 Dept. Agr., 1914, PP- 3, 4)- — This report for the period following that previously 

 noted (E. S. R., 32, p. 449) presents brief notes on the insects of siiecial impor- 

 tance. 



The pink sugar-cane borer (Scsamia nonagrioides) is said to show remarkable 

 partiality to maize in the deposition of its egg ; thus the larvse may be readily 

 destroyed upon a large scale by the use of maize as a trap crop. The eggs of 

 this pest are said to be parasitized by Ceraphron beneficiens. The artichoke 

 moth (Porbe bjcrkandrella) was particularly prevalent during the period under
