The catalpa midge, II. A. (Iossaku {Ohio »S7«. Bui. 1!)7, pit. 13, fiyn. 9). — 

 Termiiiiil buds, leaves, and pods of the varieties of catalpa found in Ohio are 

 said to lie considerably injured l>y the attaclcs of Vccidomyia catnlpw. Hundreds 

 of spots were often found on sinjjle leaves and larjj;e fruiting trees so badly 

 attaelvetl that from one-third 1o one-li.ilf of the leaves died from the injuries. 

 The adults appear in May and in .Time larvje are found in abundance on the 

 leaves and in the terminal buds. The larvae emerge in abont 24 hours after 

 tlie eggs are deposited. In niidsuninier from 3 to 4 weeks appear to be 

 required for the completion of the life cycle. The larvae are fed upon by lace 

 wings and jiarasitized by the chalcid Zatropi.H ctitdljjw. As the larvje drop to 

 the ground ;uid pupate near the surface of the soil, it is recommended that 

 jilowing be done in the late fall or early spring and that cultivation be carried 

 on through the sununer. The application of kainit l)eneath the trees or the 

 drenching of the soil in early spring with kerosene emulsion (1 to 10) is also 

 reconnnended. 



The importation of Tetrastichus xanthomelsenae, L. O. Howard (Jour. Econ. 

 But., 1 (IHOS), No. 5, pp. 28{-289, fl<j. 1). — The author presents an account of 

 the biological observations made by Marchal on an egg parasite which has 

 api)arently stopped the ravages of the elm-leaf beetle in France. This parasite 

 <'P. .rdiUJiotnchriKt) was introduced from France in April, 1^08, and bred at 

 the gipsy-moth laboratory at Melrose Highlands, Mass., by W. F. Fiske, of the 

 Bureau of Entomology of this Department, under the author's direction. The 

 breeding notes are here presented. Adult parasites have been liberated in two 

 localities near Boston, Mass., at New Brunswick, N. J., and at Washington, D. C. 



Notes on maple mites, P. ,1. I'akrott (Jour. Econ. Ent., 1 (It)OS), No. -5, 

 pp. 311-3 IS). — Fifteen species of mites that thrive on maples have been 

 recognized, including the two Old World sitecies PhyUocoptcs fiiimnatipin and 

 O.rj/plcuritcs' .scrratUK, which are recorded for the first time in this country. 

 Descriptions are presented of the fusiform maple gall (P. arcris-crumcna 

 [Eriopliifcs accricola]), and the bladder maple gall ( /'. \E. (piddriprs]). the 

 two connnon and widely distributed species on the hard ;ind soft maples. 



A mosquito which breeds in salt and fresh water, C. S. Banks (Philippine 

 Jour. Sri., li. Mrd. ,SVi., 3 (19()H), No. J,, i)p. 33r)~339, pis. 2, maps 3).— The 

 author reports the results of an investigation made of an epidemic of iestivo- 

 autunuial malaria in the mountain province of Lepanto-Bontoc. Adults of 

 Ml/zdiin/id ludlonii were found at Boutoc in dwellings and the larvie, pre- 

 viously known to develop only in sea water, were found breeding in the 

 greatest abundance in rivers and streams of the vicinity. The water in that 

 region, which is strongly impregnated with lime, is said to contain a high 

 percentage of aluminum sulphate. 



While larva' of an undetei-inined culicine were found associated with those 

 of .1/. luiUoirii no other spcn-ies of Anoi)helina' wa,s found. This is considered 

 the first record of a sitecies of mosquito developing naturally in botli salt and 

 fresh wjiter. 



The author concludes that altitude (up to l.HOO meters) has no appreciable 

 influence upnii tlie development of .1/. ludlowii and that there is little hope of 

 ridding a coniniunity like Cervantes of this insect owing to the peculiar topo- 

 graphical features.

The house mosquito, a city, town, and village problem, .T. B. Smith (Nnr 

 Jrrscii Stiis. Hul. 21(1. pp. 3-21, pis. 2. fiys. 7). — The woi'k done on the salt 

 marshes of New Jersey since 1U04 is said to have itructically eliminated the
