morning and evening, one from December 13 until February 13, sliowing an 

 increase in weight of 55 lbs., wbile the second showed an increase of 49 lbs. 

 from December 22 to February 12. This was during the driest months of the 

 year. . . . 



"The coffee planters particularly have become interested in the raising of 

 bees, not only for the honey but because bees are very useful in pollenizing 

 coffee in seasons when there is a great amount of rain during bloom. The 

 pollen in the coffee is carried by the winds from flower to flower, but, if there 

 is much rain, very little bloom is set as only the dry pollen is carried by wind; 

 during rainy periods the bees visit the flowers and distribute the pollen in 

 their honey gathering. Coffee plantations also afford excellent fields for bees 

 to work in as honey is obtained from the coffee shade as well as from the 

 coffee itself." 



In this circular the apparatus required for bee keeping is described and 

 directions given for the handling of bees and honey, together with brief ac- 

 counts of the principal honey plants and insect pests and diseases. It is stated 

 that bee moths are found on the island but only attack weakened colonies. 



Observations on the parasitism of Isaria farinosa, with, special reference 

 to the larch. sawfl.y (Nematus erichsonii), H. T. GiJssow {Proc. and Trans. 

 Roy, Soc. Canada, 3. sen, 4 {1910), Sect. IV, pp. 95-99).— The experiments 

 here reported show that this fungus (/. farinosa) is truly parasitic on larch 

 sawfly cocoons. 



" The fungus /. farinosa is capable of vegetating saprophytically for a con- 

 siderable length of time, provided sufficient moisture is available. The condi- 

 tions under which this mode of life was observed were close to natural condi- 

 tions. Owing to this saprophytic mode of life there remains little doubt that 

 the pupating larvae of the larch sawfly infect themselves when taking to the 

 ground for pupation." 



Experiments conducted confirm other observations in indicating that the 

 disease may be artificially introduced after the cocoon has been spun. 



Descriptions of new Hymenoptera, J. C. Crawford {Proc. U. S. Nat. Mus,, 

 39 {1911), pp. 617-623, figs. 3). — This paper presents descriptiojis of new para- 

 sites, together with 2 new species of bees. The parasites described as new are 

 Trichomalus apanteloctenus, reared from an Apanteles on ~Naraga diffusa in 

 Japan ; Dipachy stigma cushmani, which is the type of a new genus, bred from 

 Stephanoderes sp. at Tallulah, La.; Winnemana argei, which represents a new 

 genus, reared from the eggs of Arge sp. at Plummers Island, Md. ; Euplectrus 

 fukaii, reared from N. diffusa in Japan; E. Icocbelei from Japan, host unknown; 

 E. kmcanw. bred from Parnara guttatus in Japan; Elachertus Jiyphantriae, 

 reared from Hyphantria cunea at Cuero, Tex.; and Cratotechus Jioplitis from 

 Japan, host not given. The author also records Pleurotropis atamiensis as 

 reared in Japan from N. diffusa and probably a secondary parasite on Euplectrus 

 fukaii, and Trichogramma japomcicm as reared from the eggs of Chilo simplex 

 in Japan. 



Japanese sawfl.ies in th.e collection of tlie United States National Museum, 

 S. A. RoHWEK {Proc. TJ. 8. Nat. Mus., 39 {1911), pp. 99-120) .—Four genera, 

 1 subgenus, 24 species, and 2 subspecies are here described as new. 



On the Hymenoptera of the Georgetown Museum, British Guiana, P. Cam- 

 ebon {Timehri, Brit. Guiana, n. ser., 1 {1911), No. f, pp. 153-186). — This paper 

 includes descriptions of numerous new species of parasitic Hymenoptera of the 

 families Ichneumonidte, Pimplidse, and Ophionidse, 



Tick control in relation to the Rocky Mountain spotted fever, R. A. Cooley
