562 EXPERIMENT STATION EECORD. 



ical aud descriptive notes on O. tarandi. The pupal period of a larva squeezed 

 out in May from a reindeer received at the Dublin Zoological Gardens was 

 found to be about 6 weeks. 



A note on the preservation of bamboos from the attacks of the bamboo 

 beetle or shot-borer, E. P. Stebbing {{Indian Forest Dept.] Pamplilet 15, 

 Forest Zool. Her. 2, 1910, pp. IS, pis. 2).— A report of experiments with 

 Dinoderus minutus. 



Technical papers on miscellaneous forest insects. — II. The genotypes of 

 the sawfiies and woodwasps, or the superfamily Tenthredinoidea, S. A. 

 RoHWER {V. 8. Dept. Agr., Bur. Ent. Bui. 20, pt. 2, tech. ser., pp. 69-109).— In 

 this paper the author presents an alphabetical catalogue of the generic names 

 used in the Tenthredinoidea, which includes the name of the author, original 

 reference, type species, and authority for the type. An index to the genotypes 

 follows. He then discusses the synonymy of certain genera and the work of 

 W. H. Ashmead on the Tenthredinoidea, including an alphabetical list of the 

 genera of this superfamily that were described by Ashmead, with the deter- 

 mined synonymy, a bibliography of this author's more important writings on 

 the group, and descriptions of his genera and si)ecies. 



In the preparation of this paper studies were made of the types of described 

 genera and species in the principal collections of Europe. 



Additions and corrections to the g'enotypes of the sawflies and wood- 

 wasps, or the superfamily Tenthredinoidea, >S. A. Rohwer {Ent. News, 22 

 {1911), No. 5, pp. 218, 219). — Additions to the bulletin above noted. 



A contribution to the knowledge of the galls of Java, W. and J. Van 

 Leeuwen-Reijnvaan {Rec. Trav. Bot. N^erJand., 6 {1909), pp. 67-98, pi. 1, 

 figs. 6; Ann. Jard. Bot. Buitenzorg, 2. ser., 8 {1910), pt. 2, pp. 119-183, pis. 8).— 

 The first paper deals with the anatomy and development of the gall on 

 Erythrina Uthospcrmn made by Agromysa erythrinw. The second paper takes 

 up the development of several galls made by mites. 



Gametogenesis of the gall fly, Neuroterus lenticularis, I, L. Doncaster 

 {Proc. Roy. 8oc. [London], Ser. B., 82 {1910), No. B- 553, pp. 88-113, pis. 3).— 

 The summer (bisexual) generation of this cynipid was originally described as 

 Spatliegaster haccarum. The galls from which the spring (agamic) generation 

 emerge are lenticular growths found on the underside of oak leaves in October. 

 From these galls the flies hatch out early in April. Since in each case ob- 

 served only one sex emerged from the balls produced by one fly, although the 

 numbers were small, the author thinks it is justifiable to conclude that every 

 fly of the agamic generation produces eggs of only one sex. Cases of this kind 

 are said to be known in the Aphididss and in Rotifers but not hitherto, so 

 far as known, in the Hymenoptera. 



Concerning the morphology of Trypanosoma franki, P. Knuth {Ztschr. 

 Infektionskrank. u. Hyg. Haustiere, 6 {1909), No. 1, pp. 39-f,5, fig. i).— The 

 author concludes that morphologically T. franki is most closely related to 

 T. theileri. 



The development of Trypanosoma lewisi outside the vertebrate host, N. H. 

 SWELLENGREBEL and C. STRICKLAND {Parasitology, 3 {1910), No. 3, pp. 360-389, 

 figs. 21 ) . — " From the results of our experiments we may conclude that the 

 development of T. lewisi outside the invertebrate host is not confined to one 

 species or genus, but may take place at least in the rat louse [Hwmatopinus 

 spinulosus] and the rat flea [Geratophyllus fasciatus], and also (though per- 

 haps more incompletely) in the bedbug. We see further that development 

 needs not always to be combined with longevity in the invertebrate host, but 

 that sometimes life without development may be longer than with it (behavior 

 in the tick [OrnitJiodoros mouhata] compared to that in the louse).
