attacks of which occur in the evening after a shower, is the most dreaded. The 

 so-called tarantula spider (Avicvlaria ovioularia) attacks the colony alter 

 nightfall. 



New genera and species of Encyrtinre from California parasitic in mealy- 

 bug's, P. II. Timhkui.akk (I nir. Cal. Pub*. Ent., / (1918), No. 8, pp. 3.',7-367, 

 figa. 7). — Three new genera and six new species an- described by the author, 

 namely, AcerophaQUS fasciipcnnis n. sp., reared from early larval stages of 

 Pscudococcus crairii at Uplands; .1. paUidus n. sp., reared from p. gerbasanUB, 

 Sespe Canon; Stemmatoeterea <ii>t<rus n. g. and n. sp., reared from /'. timber- 

 lukci from Millbrae; Paeudococcobiua fwnipenn&8 n. sp., reared from /». aoloni 

 at Uplands; Pseudococcobius clauseni n. sp., reared from Eriutn sp. on cactus 

 at Riverside; and Tanaomastix claripennia n. sp., reared from P. rgcmi at Pasa- 

 dena. The genus Cirrhencyrtus is erected lor l'svudococcobius chrhorni Tim- 

 berlake and Tanaomastix for ParaleptomaaHx abnormia Girault. 



An interesting habit of a wax moth parasite, S. A. Graham (Ann. Ent. 

 Nor. Amer., 11 (1918), No. 2, pp. 175-180. pi. 1. Jigs. 2).— This is a report of 

 studies of the pteromalid parasite Dibrachya Cli8i0campce, heretofore recorded 

 as a parasite of the forest tent caterpillar, and now recorded for the first time 

 as a parasite of the bee moth (Qalleria meUonella). 



During the course of investigations at the Minnesota Experiment Station the 

 author reared this parasite from the bee moth in large numbers. Its ovipositor 

 i^ thrust into the larva of the bee moth repeatedly and, when in the course of 

 6 to 24 hours the larva thus stabbed becomes sluggish and finally dies, eggs are 

 deposited on the surface of the body, usually in the wrinkles in the skin. In 

 from 3 to 7 days the larva? hatch out and fasten themselves to the body of 

 the host, where they feed from 2 to 4 weeks and even longer. From 14 to 25 

 days are required for the completion of the pupal stage, the life cycle from egg 

 to adult varying from 31 to 59 days. 



Notes on a new mite attacking valley cottonwood, P. J. O'Gara (J^ur. 

 Boon, lint., 11 (1918), No. 5, p. J^30, pi. 1). — The author records the occurrence 

 of what may prove to be a new species of Eriophyes on poplar (Populus wis- 

 lizeni) in the vicinity of El Paso, Tex. 



Studies on the iguana tick, Amblyomma dissimile. in Panama, L. H. 

 Dunn (Jour. Parasitology, 5 (1918), No. 1, pp. 1-10). — This is a report of bio- 

 logical studies of A. dissimile in the Canal Zone. 



The biology of Amblyomma dissimile, with an account of its power of re- 

 producing parthenogenetically, G. E. Bodkin (Parasitology, 11 (1918). No. 1, 

 pp. 10-17, pis. 2, fig. 1). — A report of studies conducted by the Government 

 economic biologist of British Guiana. 



On the life cycle of the fowl cestode, Davainea cesticillus, J. E. Ackkrt 

 (Jour. I'arasitology, 5 (1918), No. 1, pp. Jfl-lfS. pi. 1). — Working at the Kansas 

 Experiment Station, the author has demonstrated experimentally that D. cesti- 

 cillus may be transmitted by the house fly. 



FOODS— HUMAN NUTRITION. 



Place of milk and vegetables in the diet, H. C. Shekman (Awcr. Med., «. 

 8er., IS (1918), No. 6, pp. 361-369, figs. 5).— This article aims to teach a higher 

 appreciation of milk and vegetables as food, pointing out that both are rich in 

 calcium and green vegetables also in fat-soluble A. The author suggests as a 

 general guide that as much money should be spent for milk as for meat, ami 

 that as much might well be spent for fruit and vegetables together as for 

 meat.
