10V)2 EXPERIMENT STATION RECORD. 



Jiys. 116). — 111 this rejiort tlie atitlior given an account of tlie species of the family 

 Ceranibycida' found in Arniorica, with notes on their distribution. 



Flour beetle (Tribolium confusum) [Jour. Bd. Ayr. \_London'], 11 {ID04), No. 2, 

 pj). lOU, 110). — Tlie habits of this l)eetle are briefly noted. The most effective 

 remedy in controlling it is bisulphid of carbon, and directions are given for api)lying 

 this treatment. 



A natural history of tlie British, lepidoptera, IV, J. W. Tutt {London: Swan, 

 Sonnenache'm <k Co., l'M4, pp. XyiI-\- 535, j>ls. 3). — This constitutes a continuation of 

 the author's elaborate monographic work on the British lepidoptera, and conoludes 

 the account of the superfamily Sphingides. The various observations made Ijy the 

 author concerning the life history of the species considered in the volunje are recorded 

 with the usual detail. In the preface the author discusses certain problems connected 

 with the reform of the nomenclature of lepidoi>tera. The volume is provided with 

 an index and also Avith a general index io the four volumes already puljlished. 



Experiments in 1893, 1894, and 1896 upon the color relation between 

 lepidopterous larvse and their surroundings, E. B. Poultox [Trans. Ent. Soc. 

 London, 1903, pit. 3, pp. 311-374, ph- 3). — The author carried on an elaborate series 

 of experiments to determine the relation between the color of insects and their 

 environment, especially ujjon Odoniopera hidentata and Gastrojxichu quercifolia. The 

 behavior and color changes of the larvae through their various stages are minutely 

 described. It was found that the effect of dark surroundings upon the early stages 

 was very marked. The influence of a dark environment even for one molting stage 

 was manifested in a decided change of color. 



The economic status of the Fulgoridse, H. Osborn [Proc. Soc. Prom. Agr. Set., 

 1904, pp. 32-36). — Data are presented on the feeding habits and economic importance 

 of these insects. It appears that thus far little work has been done along this line. 

 Especial reference is made to the injurious attacks of Liburnia campestris, L. lutulenta, 

 and cane leaf-hopper in Hawaii. 



Notes on the nests of bees of the genus Trigona, C. O. Waterhouse ( Trans. 

 Ent. Soc. London, 1903, pt. l,iyp. 133-136,2)1. 1, figs. 3). — The method of the construc- 

 tion of nests by this genus of bees is described in detail with notes on the differences 

 observed in the nests of different species. 



The suppression and control of the buffalo gnats in the valley of the lower 

 Mississippi River, F. M. Webster [Proc. Soc. Prom. Agr. ScL, 1904, p>P- 53-72, 

 figs. 7). — Previously noted from another source (E. S. R., 15, p. 545). 



A new method of combating Atta sexdens and other ants injurious to 

 cultivated plants, A. Hempel [Bol. Agr. Sao Paulo, 5. ser., 1904, No. 2, p}p. 72- 

 74). — Brief directions are given regarding the use of parasitic fungi in the control of 

 injurious ants and other insect pests. 



The spinning habits of the North American Attaci, F. M. Webster {Canad. 

 Ent, 36 {1904), No. 5, pp. 133, 134). — During the past 25 years the author has 

 observed the position of the cocoons of Samia cecropia and related species. The 

 downy woodpecker destroys the insects by puncturing the cocoons and feeding upon 

 the contents. Some species of insects belonging to the group under discussion have 

 apparently changed the location of the cocoons so that they are not so conspicuous, 

 and thus avoid destruction by birds. 



The nutrition of the bee moth, N. Sieber and S. Metalnikow {Arch. PJiysiol. 

 IPfii'iger], 102 {1904), No. 5-6, pp. 269-286) .—The feeding habits of the bee moth 

 were studied for the purpose of determining the actual materials eaten by this insect, 

 and their relative nutritive importance. It was found during this study that bees- 

 wax must be considered as an important and necessary part of the diet of bee 

 moth in order that this insect may thrive and multiply. Extracts were made from 

 the digestive tract of the insect for the purpose of gaining more exact data concern- 

 ing the digestive ferments in this pest.
