The fumigation of nursery stock, B. W. Doutii.A.ss (Ind. Htatc Ent. Jiiil. 2, 

 mi. !), ji(js. ,i\. — I)uriii,tr tlu> simiiuor of 1!)()7 over oO nurseries in Indiaim were 

 found infested with the S:in Jose scale. The author describes a funiijiation 

 house of concrete that was built for a nursery man at a total cost of less than 

 ,$100. I'hotographs are jjiven of the house while under construction and after 

 completion. 



Attention is called to the I'act that the formula j,nven for fumi,i.'ation Is based 

 niton the chemically pure potassium cyanid and not ujion the connnercial brand, 

 which averaiies less than HO iter cent pure. Examinations made of samples of 

 ixttassium cyanid obtained from inirseries over the State where fumigation is 

 carried on show that as a rule the article sold by the averaj^e drujiiiist is of the 

 connnercial grade. 



Directions are given by the author for the fumigation of stock and by W. C. 

 Keed for the fumigation of buds and scions. 



Descriptions of some new species and a new genus of American mosquitoes, 

 II. C. DvAK and F. Knai; i Sinitli-sii. Mixc. Collect., 52, No. 1813, pp. 2.')3-.i(i6. 

 ////. I). — The genus Dianamesus based upon the new species D. spanimi which 

 was collected in the Canal Zone, I'anama, is described as new to science. Thirty- 

 five species belonging to the genera Aedes, Bancroftia, Cnlex, Deinocerites, 

 Wyeomyia, and Limatns are also described as new. 



Mosquito comment, II. O. Dyab and F. Knab {Canad. Ent., .'/l {1909), No.S, 

 pp. 101, 102). — Culcx tnichycampa from the Canal Zone. Panama, and Acdes 

 sunsoni from Baufif, Alberta, Canada, are described as new. 



On the larval and pupal stages of Anopheles maculipennis, A. 1 mms 

 ( I'f. /, Jour. Hug. [C(i)iihrid(/c\, 7 ( 19(17). Xo. 2. pp. 291-318, pis. 2 : lit. uni- 



sltohnni. 1 (1908), No. 2, pp. 103-133. pis. 2).— The author presents a . ^tailed 

 description of the internal structure of the larva and pupa of this mosquito. A 

 Itibliography is appended to each part. 



Biology of Philippine Culicidoe, C. S. Banks {Philippine Jour, tici., A. Gen. 

 ScL, 3 (1908), No. 4, pp. 285-258, pis. 10). — Studies were made on the life his- 

 tory and habits of Worcestcria grata, Dcsvoidya jola'nsis, ^tegomyia persistans, 

 .s'. satnurensis, Huleccctomyia pseiidota'niatu, the tilaria moscpiito {Cnlex fati- 

 gans), Banksinella luteolateralis, Mansonia annnlifera, and .1/. uniforniis. The 

 larvje of W. grata are said to destroy enormous numbers of those of otlier 

 species. It is the authoi-'s opinion that Mansonia uniforniis plays a role in the 

 transmission of dengue fever as important as does Cnlex fatigans. 



New Philippine mosquitoes, C. S. Luni.ow (Canad. lUil., 'it (1909), No. 3, 

 p. 97). — A new species of mosquito collected at Parang, Mindanao. P. I., is 

 described as Oculiomyia fuller!. 



Millions and mosquitoes, II. A. P.Ai.r.ou (Imp. Depl. Agr. West Indies 

 I'ainplilet 55, 1908, pp. Id. fig. I ; West Indian liul., 9 (1909), No. }, pp. 382-390, 

 figs. '/). — An account is given of a species of small fish {(lirardinus 2i(Vciloides), 

 commoidy known as million, which largely assists in keeping some species of 

 nios(iuitoes in check through feeding upon the eggs. larv;e. and pup;e. This fish 

 has recently been introduced into SI. Kitts-Nevis, Antigua, Jamaica, St. Vin- 

 cent, St. Lucia, and Guayaciuil. and also into British (Juiana, Colon, and Bolivar. 



A note upon the possibility of the mosquito acting in the transmission 

 of leprosy, W. II. Bkinckkkiioi'I- ( Waxhini/ton, D. ('.: I'uh. lle<tltU ami Mar. 

 Ilosp. Herr. U. N., 1908, pp. 22-2'/) . — The author has found Cnlex pipiens to 

 defecate during the process of blood sucking in a way very similar to Myzoniyi<i 

 ludloirii as observed by I'.anks. Such a haltit makes it mechanically possible 

 for mosquitoes to carry lepra bacilli from lepers to well persons and highly
