162 EXPERIMENT STATION RECOED. - [Vol.37 



The plants seem to be attacked at various i >ints. Sometimes the root stock 

 is bored, or again the fruit stalk is hollowed out and collapses. A favorite 

 place of attack is the junction of the fruit and stalk, when the larva proceeds 

 into the fruit and riddles it, or the heart may be attacked before the pineapple 

 has shot above the leaves. 



Another weevil occurring in pineapples, namely, M. sericeus, appears to be 

 secondary, it being attracted from the surrounding bananas by the decaying 

 pines killed by M. ritchiei. 



Pineapples: New weevil injury in Above Rocks District {Jour. Jamaica 

 Ayr. Soc, 20 (1916), No. 8. pp. 316-SlS). — This paper gives an account of the 

 injury to pineapples caused by Metamasitts ritchiei above noted. 



The pineapple black weevil, W. Newell (Quart. Bui. Plant Bd. Fla., 1 

 (1917), No. 2. pp. .',7-50. fig. 1). — A brief account of the pe.st (Metamasius 

 ritchiei) above noted in which the author calls attention to the danger of in- 

 troducing it into Florida. 



Diseases of the honeybee, L. Bahb (Meddel. K. Yet. og Landbohojskoles 

 Serumlah., No. 57 (1915), pp. 109, pis. 2, figs. 6).— Following an account of the 

 bacteria which normally occur in the hive, the author gives summarized ac- 

 counts of the various diseases, etc., of the honeybee. 



The habit of leaf oviposition among the parasitic Hymenoptera. H. S. 

 Smith (Science, n. ser., J,.', (1916), No. 1U8, pp. 925, 926).— The observations 

 here reported relate to Perilampus hyalinus, a hyi^orparasite of the fall web- 

 worm, and are in continuation of those previously noted (E. S. R., 27. p. 2G1). 



In connection with observations of this species, which was occasionally reared 

 at Sacramento, Cal.. from Chrysopa cocoons, the author secured several adult 

 female Perilampus hovering about oleanders infostetl with .Aphis nerii and fe<l 

 upon by Chrysopa. The author has found that the eggs are deposited on the 

 leaf, thus establishing beyond doubt the habit of leaf oviposition among para- 

 sitic Hymenoptera. The eggs are numerous, one female having deposited 52 in 

 a single day. They hatch in from seven to ten days, and the first-stage larva, 

 which is of the planidium type, is active at first, crawling rapidly about, but 

 later attaches itself to the leaf by the caudal end, then standing out at right 

 angles to the surface, where it awaits the approach of the Chrysopa larva, to 

 which it attaches. 



A new genus of omphaline Eulophidae from North America, A. A. Girault 

 (Entomologist, 49 (1916), No. 6J,2, pp. 21,9, 250). — Mirnmphalomyia pcrilam- 

 poidea n. g. and n. sp. is described from Arizona. 



The North American species of Habrocytus (chalcid flies), A. A. Girault 

 (Canad. Ent., ^9 1917), No. 5, pp. 178-1S2). — A table based upon the females 

 is given of ten species of Habrocytus recognized as occurring in the United 

 States, and six species and one variety are described as new. 



Notes on coccid-infesting Chalcidoidea, I, .1. Waterston (Bui. Ent. Research, 

 7 (1916), No. 2, pp. 1,37-1. i^i, figs. .S). — Dirersinernis silvcstrii reared from 

 Lecanium riridc on coffee in Mauritius and Coccophagus acanthosccles from the 

 body of Ecrunium .sp., Sing:ip<iro, Straits Sottlonients, are described as new. 



Search for melon fly parasites, D. T. Fuli^way (Haunii. Forester and Agr., 

 IS (1916), No. 8, pp. S0,3-,S06). — The author reports upon a trip made to Singa- 

 pore, Java, and India in search of para.sites of the melon fly. The parasite 

 discovered, Opins fletchcri, was found to occur in all three localities, partic- 

 ularly in India, from whence it has been introduced by the author into the 

 Hawaiian Islands. 



During the course of several months spent in the Philippine I.slands rearing 

 the parasites, the author's attention was called to the heavy parasitism of the
